[ Rich Murray comments: As a medical layman volunteer information
activist for aspartame and related toxicity issues since January 1999,
I note with appreciation the remarkable exponential progress on all
fronts, including a rapidly emerging consensus about the primary
importance of all toxicity challenges for our world.
This lengthy review features in detail two quite different, revolutionary
contributions, from Canada, and England and China.
It is indicative of our times that the CL Nie et al. study, 2007
appears in a free, open access journal-- indeed,
as all life and death information must.
Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a
30-page review as 3 pages a decade ago -- and such reviews
are archived forever in multiple collections, open via global search
engines to a billion Net citizens.
Perforce, and increasingly happily, all societal entities will have to
operate by high and shared voluntary universal standards
for the common good. ]

(2007) Formic Acid, a Novel Metabolite of Chronic Ethanol
Abuse, Causes Neurotoxicity, Which Is Prevented by Folic Acid
Alcoholism: Clinical and Experimental Research 31 (12), 2114-2120.
doi:10.1111/j.1530-0277.2007.00541.x
Abstract
Background:
Methanol is endogenously formed in the brain and is present as a
congener in most alcoholic beverages.
Because ethanol is preferentially metabolized over methanol (MeOH)
by alcohol dehydrogenase, it is not surprising that MeOH
accumulates in the alcohol-abusing population.
This suggests that the alcohol-drinking population will have higher
levels of MeOH's neurotoxic metabolite, formic acid (FA).
FA elimination is mediated by folic acid.
Neurotoxicity is a common result of chronic alcoholism.
This study shows for the first time that FA,
found in chronic alcoholics, is neurotoxic
and this toxicity can be mitigated by folic acid administration.
Objective:
To determine if FA levels are higher in the alcohol-drinking
population and to assess its neurotoxicity in organotypic
hippocampal rat brain slice cultures.
Methods:
Serum and CSF FA was measured in samples from both ethanol
abusing and control patients, who presented to a hospital emergency
department. [ CSF = Cerebral Spinal Fluid ]
FA's neurotoxicity and its reversibility by folic acid were assessed
using organotypic rat brain hippocampal slice cultures using clinically
relevant concentrations.
Results:
Serum FA levels in the alcoholics
(mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls
(mean ± SE: 0.154 +- 0.009 mmol/l, n = 82) (p < n =" 20),">0.15 mmol/l in CSF of 3 of the 4 alcoholic cases.
Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours
to the rat brain slice cultures caused neuronal death as measured by
propidium iodide staining.
When folic acid (1 umol/l) was added with the FA,
neuronal death was prevented. [ umol = micromole ]
Conclusions:
Formic acid may be a significant factor in the neurotoxicity of
ethanol abuse.
This neurotoxicity can be mitigated by folic acid administration
at a clinically relevant dose.
Key Words:

NEUROTOXICITY AND BRAIN damage are common
concomitants findings of chronic alcoholism
(Carlen and Wilkinson, 1987; Carlen et al., 1981; Harper,
2007).
The cause of ethanol-induced neurotoxicity is still unclear.
We present here a novel hypothesis for neurotoxicity:
increased formic acid (FA) levels produced from methanol
(MeOH), whose catabolism is blocked by ethanol.
Axelrod and Daly (1965) demonstrated the endogenous formation
of MeOH from S-adenosylmethionine (SAM) in the pituitary
glands of humans and various other mammalian species.
Presence of MeOH in the breath of human subjects was
reported by Ericksen and Kulkarni (1963).
Most alcoholic beverages also have a small amount of MeOH
as a congener (Sprung et al., 1988).
As ethanol (EtOH) has a higher affinity for
alcohol dehydrogenase (ADH) than MeOH,
EtOH is preferentially metabolized (Mani et al., 1970).
As a result, MeOH accumulation from endogenously produced
MeOH, and/or, that consumed as part of an alcoholic beverage,
has been reported in concentrations up to 2 mmol/l in heavy
drinkers (Majchrowicz and Mendelson, 1971).
Toxicity resulting from MeOH consumption is extensively
documented in both humans and animals and has been
attributed to its metabolite, FA (Benton and Calhoun, 1952;
Roe, 1946, 1955; Wood, 1912; Wood and Buller, 1904).
The rate of formate oxidation and elimination is dependent on
adequate levels of hepatic folic acid, particularly hepatic
tetrahydrofolate (THF)
(Johlin et al., 1987; Tephly and McMartin, 1974).
Significantly higher formate levels were obtained when
folate-deficient animals were exposed to MeOH as compared
with folate-sufficient animals (Lee et al., 1994;
McMartin et al., 1975; Noker et al., 1980).
To understand ethanol's toxicity, one must consider FA
produced from MeOH, and its elimination mediated by folic acid.
We postulate that in the chronically drinking patient,
we will find higher levels of FA than in the nondrinking population,
and that formate is neurotoxic.
We also hypothesize that treatment with folic acid, which is a
critical factor in the catabolism of FA, can prevent or
diminish FA neurotoxicity.
METHODS
Patient Samples
During our study period of 4 months, 23 patients whose serum
showed the presence of both ethanol and trace amounts
(<2 n =" 82)" n =" 20)" n =" 7" nm =" nanometer" p =" NS" nd =" not" control =" no" acid =" 1" p =" NS"> *OH + Fe,3+ + OH,-
HCO2,- + *OH --> *CO2,- + H2O
*CO2,- + O2 --> CO2 + *O2,-
Chance has shown that formate can be metabolized by the
catalase-peroxidative system (Chance, 1950).
When anti-oxidants are depleted, increased ROS are formed
(Treichel et al., 2004).
Formic acid-induced cell damage has been attributed
to the generation of the cytotoxic ROS species.
FA disrupts mitochondrial electron transport and energy production
by inhibiting cytochrome oxidase activity (Nicholls, 1975, 1976;
Sharpe et al., 1982)
and causes cell death by increased production of cytotoxic ROS
secondary to the blockade of the electron transport chain
(Reed and Savage, 1995).
Formyl group (CHO) is transferred to THF
resulting in the formation of carbon dioxide and water
Makar et al., 1990; Medinsky et al., 1997).
Our organotypic brain slice studies suggest that there is a
dose and time relationship between FA and neuronal cell death.
FA levels achieved in the blood of the alcohol drinking
population can cause neuronal cell death.
The FA concentrations we used in our studies are representative
and were achieved in 2 of the 4 patients in whom we had sequential
samples.
It is remarkable that neuronal cell death could be prevented
by folic acid, although the mechanism of this protection is unknown.
There is a large body of literature relating folic acid deficiency
to neural tube defect, but, there are no references
relating low levels of FA to neurotoxicity.
There are a few studies relating FA and mitochondrial inhibition,
with MeOH intoxication and retinal damage
(Seme et al., 1999, 2001).
Another study demonstrated toxic effects of high concentrations
of formate in dissociated primary mouse neural cell cultures
(Dorman et al., 1993).
The concentration of formate that resulted
in 50% lactate dehydrogenase leakage after an 8-hour incubation
was estimated to be 45 mmol/l.
The total intracellular ATP concentration was significantly
decreased following either 20 or 40 mmol/l FA
exposure for 8 hour.
This is consistent with the hypothesis that FA may inhibit
mitochondrial function resulting in decreased intracellular ATP
and formate-induced neurotoxicity.
Using organotypic hippocampal slices, which preserve neuronal
circuitry and are easily accessible for experimental manipulations
(Stoppini et al., 1991),
our group has previously shown that
free radical overproduction in hippocampal pyramidal neurons
during ischemia/reoxygenation
depended on the activation of glutamate receptors,
and was associated with elevations of intracellular calcium.
Mitochondria are thought to be the principal source of
glutamate-mediated, calcium-dependent free radical production
in cultured cortical neurons
(Dugan et al., 1995; Reynolds and Hastings, 1995).
Although we did not investigate FA levels below 1 mmol/l,
it is conceivable that a continuous exposure to low,
but, above normal levels (>0.15 mmol/l), may also be cytotoxic
and may be part of the pathology of alcohol-related
organ damage (Jiang et al., 2003)
including the fetal alcohol spectrum disorder.
CONCLUSION
Our studies, for the first time, have shown that MeOH from
endogenous sources and from congeners present in alcoholic
beverages can lead to FA concentrations that are neurotoxic.
Therapeutic intervention with folic acid could be a significant
treatment modality in preventing FA mediated cytotoxicity,
especially neurotoxicity, in alcoholics.

Brief Summary:
Methanol in small amounts is present along with ethanol in beverage
alcohol.
[Murray: and about the same amounts from aspartame diet sodas]
The body's natural enzymes preferentially metabolize ethanol while
methanol breaks down into highly neurotoxic Formic Acid.
Use of high levels of Folic Acid was found to inhibit brain damage
caused by the methanol.
The use of Folic Acid during pregnancy has been recommended
for several years to prevent neural tube defects.
However, this study indicates that even higher levels of Folic Acid
can be very beneficial to the developing baby, particularly where
alcohol exposure is a factor.
Folic Acid is mandated as an additive to all flour sold in Canada.
The debate has begun on its required addition to all beverage
alcohol to help mitigate damage caused to both infants and adults.

Abstract
Methanol is produced endogenously in the pituitary glands of humans
and is present as a congener in almost all alcoholic beverages.
Ethanol and methanol are both bio-transformed by alcohol
dehydrogenase; however, ethanol has greater affinity for the enzyme.
Since ethanol is preferentially metabolized by the enzyme, it is not
surprising that trace amounts of methanol, most likely originating from
both sources, have been reported in the blood of people
who drink alcohol.
Toxicity resulting from methanol is very well documented
in both humans and animals and is attributed to its toxic metabolite
formic acid.
To understand ethanol toxicity
and Fetal Alcohol Spectrum Disorders, it is important to consider
methanol and its metabolite, formic acid, as
potential contributors to the toxic effects of alcohol.
Accumulation of methanol suggests that alcohol-drinking
population should have higher than baseline levels of formic acid.
Our preliminary studies do indeed show this.
Chronic low-level exposure to methanol has been suggested to
impair human visual functions.
Formic acid is known to be toxic to the optic nerve.
Ophthalmological abnormalities are a common finding in children
whose mothers used alcohol during pregnancy.
Formic acid, a low molecular weight substance, either crosses the
placenta or may be formed in-situ from the water soluble methanol
that crosses the placenta.
Embryo toxicity from formic acid has been reported
in an animal model.
To assess neurotoxicity we applied low doses of formic acid
to rat brain hippocampal slice cultures.
We observed neuronal death with a time and dose response.
Formic acid requires folic acid as a cofactor for its elimination.
Animal studies have shown that when folate levels are low, the
elimination of formic acid is slower and formate levels are elevated.
When folic acid was added along with the formic acid
to the brain slice cultures, neuronal death was prevented.
Therefore, folate deficient chronic drinkers may be at higher risk of
organ damage.
Women who are folic acid deficient and consume alcohol may have
higher levels of formic acid and should they become pregnant,
their fetus may be at risk.
To our knowledge low level chronic exposure to formic acid and its
relationship to folic acid in men or women who drink alcohol has
never been studied.
Our hypothesis is that the continuous exposure to low levels of
formic acid is toxic to the fetus and may be part of the etiology of
Fetal Alcohol Spectrum Disorders.

eyelid contact dermatitis by formaldehyde from aspartame,
AM Hill & DV Belsito, Nov 2003: Murray 4.4.4 rmforall [150 KB]
[ Extracts ]
McMartin, KE et al 1979, put 3,000 mg/kg methanol in the
stomachs of small monkeys and, 18 hours later found accumulation
of formate in liver, kidney, optic nerve, cerebrum, and midbrain
in 2 of three monkeys.
Biochemical Pharmcacology 1979: 28; 645-649.
Lack of a role for formaldehyde in methanol poisoning in the monkey.

K.E. McMartin and T.R. Tephly, authors of many pro-aspartame
studies, in Biochemical Pharmacology (1979) remarked,
"It is now generally accepted
that the toxicity of methanol is due to the formation of toxic
metabolites, either formaldehyde or formic acid."
They put damage doses of methanol into the stomachs
of three monkeys,
and, using insensitive tests, found no formaldehyde in many tissues --
except for a single datum in the midbrain,
1.5 times their detection limit.
They did report widespread accumulation of formic acid
in five tissues.
The use of inadequate tests is common in industry research that is
funded to claim the safety of profitable toxins.
Since then, industry scientists have been very wary of doing studies
on primates, which all too easily show the dangers to humans.
"Abstract [ not given in PubMed ]:
[ My briefer comments are in square brackets. ]
Methanol was administered [ by nasogastric tube ] either to untreated
cynomolgus monkeys [ 2-3.5 kg ] or to a folate-deficient cynomolgus
monkey which exhibits exceptional sensitivity to the toxic effects of
methanol.
Marked formic acid accumulation in the blood and in body fluids and
tissues was observed.
No formaldehyde accumulation was observed in the blood and no
formaldehyde was detected in the urine, cerebrospinal fluid, vitreous
humor, liver, kidney, optic nerve, and brain in these monkeys at a
time when marked metabolic acidosis and other characteristics of
methanol poisoning were observed.
Following intravenous infusion into the monkey, formaldehyde was
rapidly eliminated from the blood with a half-life of about 1.5 min
and formic acid levels promptly increased in the blood.
Since formic acid accumulation accounted for the metabolic acidosis
and since ocular toxicity essentially identical to that produced in
methanol poisoning has been described after formate treatment,
the predominant role of formic acid as the major metabolic agent
for methanol toxicity is certified.
Also, results suggest that formaldehyde is not a major factor in the
toxic syndrome produced by methanol in the monkey."
"It is now generally accepted that the toxicity of methanol is due to
the formation of toxic metabolites (1,2),
either formaldehyde or formic acid."
So, this is an acute toxicity study, with little relevance for chronic
long-term, low-level exposure.
Monkeys, like people, are susceptible to methanol toxicity.
This team cites their six previous methanol in monkey studies,
from 1975 to 1977.
The report is difficult to understand, since the three monkeys were
treated differently, and different assays were used.
For the methanol sensitive, folate-deficient monkey A, the assay
used was the chromatropic acid method,
with a detection limit of .025 mmol/L.
None of the five tissues showed any formaldehyde with this assay,
except the midbrain, 0.14 mmol/kg wet weight tissue
[ units converted from their 0.14 micromole/gm -- just
1.5 times the detection limit of .09 mmol/kg wet tissue weight
(given on p. 648).
[ Since 1 kg of water is 1 L, 1 mmol/kg is equivalent to 1 mmol/L. ]
Meanwhile, in the methanol sensitive, folate-deficient monkey A,
the blood formate level rose by 18 hours from 0.18 to 10.02 mEq/L.
[ I assume that a mEq is equivalent to a mmol -- let me know
if I'm wrong. ]
The formate detection limits for the assays were not given
in this report.
The formate level in the vitreous humor of the eye of monkey A
was 7.90 mEq/L.
It is well known that formate is extremely damaging to the eye.
For unexplained reasons, formate levels in the five tissues and
cerebrospinal fluid were not measured in the methanol sensitive,
folate-deficient monkey A.,
in the cerebrospinal fluid of monkey B,
or in the optic nerve of monkey C.
Formaldehyde was not measured in the optic nerve of Monkey A.
The kidney formate level for monkey B was 6.33
and for C was only 0.44,
with no comment or explanation given.
The experiment seems arbitrary, capricious, and erratic.
For monkey A, after 18 hours, the urine formaldehyde level was
below detection level, while urine formate was 115.80 mEq/L -- so
much of the formaldehyde had been converted into formic acid,
another cumulative, potent toxin.
"In the presence of high formate values and definitive evidence of
toxicity in methanol-poisoned monkeys, no measurable formaldehyde
was found in the body tissues that were tested."
It is reasonable to surmise that more sensitive assays would have found
formaldehyde and formate bound to and reacted with a variety of cellular
substances in all tissues -- just as the 1998 Trocho study confirmed.
(Appendix E)
Monkeys B and C were normal, not extra vulnerable to methanol,
and were given 3,000 mg/kg methanol, and samples taken at 18 hr.
Formaldehyde was detected only in the blood of Monkey B,
while formate was found in 8 and 10, respectively,
of the 10 fluid and tissue samples in Monkeys B and C.
For instance, the lowest value of formate, except for zero-time blood,
for each monkey was in the midbrain, 2.16 mmol/kg for Monkey B
(24 times the detection limit for the chromatropic acid method)
and 1.02 mmol/kg (1.3 times the detection for the dimedon method)
for Monkey C.
This shows accumulation of formate in liver, kidney, optic nerve,
cerebrum, and midbrain.
"Thus, whereas one can associate formate intimately with ocular
toxicity in the monkey, no association of formaldehyde with ocular
toxicity can be made at this time.
It is not possible to completely eliminate formaldehyde as a toxic
intermediate because formaldehyde could be formed slowly within
cells and interfere with normal cellular function without ever obtaining
levels that were detectable in body fluids..."

The toxicity of methanol.
Tephly TR.
Department of Pharmacology, University of Iowa, Iowa City 52242.
"Abstract:
Methanol toxicity in humans and monkeys is characterized by a latent
period of many hours followed by a metabolic acidosis
and ocular toxicity.
This is not observed in most lower animals.
The metabolic acidosis and blindness is apparently due to
formic acid accumulation in humans and monkeys,
a feature not seen in lower animals.
The accumulation of formate is due to a deficiency in formate
metabolism which is, in turn, related, in part,
to low hepatic tetrahydrofolate (H4 folate).
An excellent correlation between hepatic H4 folate and
formate oxidation rates has been shown within and across species.
Thus, humans and monkeys possess low hepatic H4 folate levels,
low rates of formate oxidation and accumulation of formate
after methanol.
Formate, itself, produces blindness in monkeys in the absence of
metabolic acidosis.
In addition to low hepatic H4 folate concentrations, monkeys and
humans also have low hepatic 10-formyl H4 folate dehydrogenase
levels, the enzyme which is the ultimate catalyst for conversion of
formate to carbon dioxide.
This review presents the basis for the role of folic acid-dependent
reactions in the regulation of methanol toxicity.

Abstract
Recent studies have shown that neurodegeneration is closely
related to misfolding and aggregation of neuronal tau.
Our previous results show that neuronal tau aggregates in
formaldehyde solution and that aggregated tau induces apoptosis
of SH-SY5Y and hippocampal cells.
In the present study, based on atomic force microscopy (AFM)
observation, we have found that formaldehyde at low concentrations
induces tau polymerization whilst acetaldehyde does not.
Neuronal tau misfolds and aggregates into globular-like polymers
in 0.01 - 0.1% formaldehyde solutions.
Apart from globular-like aggregation, no fibril-like polymerization
was observed when the protein was incubated with formaldehyde
for 15 days.
SDS-PAGE results also exhibit tau polymerizing in the presence
of formaldehyde.
Under the same experimental conditions, polymerization of bovine
serum albumin (BSA) or a-synuclein was not markedly detected.
Kinetic study shows that tau significantly misfolds and polymerizes
in 60 minutes in 0.1% formaldehyde solution.
However, presence of 10% methanol prevents protein tau from
polymerization.
This suggests that formaldehyde polymerization is involved in tau
aggregation.
Such aggregation process is probably linked to the tau's special
"worm-like" structure, which leaves the e-amino groups of Lys
and thiol groups of Cys exposed to the exterior.
Such a structure can easily bond to formaldehyde molecules
in vitro and in vivo.
Polymerizing of formaldehyde itself results in aggregation of
protein tau.
Immunocytochemistry and thioflavin S staining of both endogenous
and exogenous tau in the presence of formaldehyde at low
concentrations in the cell culture have shown that formaldehyde can
induce tau into amyloid-like aggregates in vivo during apoptosis.
The significant protein tau aggregation induced by formaldehyde
and the severe toxicity of the aggregated tau to neural cells may
suggest that toxicity of methanol and formaldehyde ingestion is
related to tau misfolding and aggregation.

Introduction
Neuronal tau is an important protein in promoting and stabilizing the
microtubule system involved in cellular transport
and neuronal morphogenesis.
The tau molecule can be subdivided into an amino-terminal domain
that projects from the microtubule surface and a carboxy-terminal
microtubule-binding domain.
The discovery that incubation of bacterially expressed human tau
with sulphated glycosaminoglycans leads to bulk assembly of tau
filaments [1], making it possible to obtain structural information [2].
By using circular dichroism measurement, Schweer et al. have found
that protein tau lacks secondary structures and is considered in a
"worm-like" conformation with a high flexibility [3].
Therefore, the side-chains of amino acids such as Lys, Cys, Thr
and Ser are mostly exposed and vulnerable to chemical modification.
Recently, many laboratories have found that misfolding and
aggregation of protein tau are involved in neurodegeneration
[2], [4] - [6].
Protein tau has been found as the major component of paired
helical filaments in neurofibrillary tangles in the brains of Alzheimer's
patients, where abnormal hyper-phosphorylation induces tau to
misfold and form the paired helical filaments,
depositing in the cytoplasm of neurons [7] - [10].
Recently, a great deal of evidence has demonstrated that oxidation
and glycation stresses are key causal factors of neuronal degenerative
diseases [11] - [13].
Both of them inevitably produce a variety of unsaturated carbonyls
as intermediates, like malondialdehyde and 4-hydroxynonenal,
which usually cause carbonyl-amino crosslinking and lead to
accumulation of irreversible changes (like lipofuscin) related to
various neurodegenerative diseases in particular [14] - [16].
Such carbonyl stress-related reactions (carbonylation) can form
unstable and reversible 1:1 amino-carbonyl (Shiff's base)
compounds at an early stage of protein modification [16], [17].
Carbonylation binds and blocks a-/e- amino groups,
and results in changes in charge and conformation of a protein.
In order to investigate the relationship between carbonylation and
protein tau misfolding, the basic and simplest carbonyl compound
formaldehyde [18] has come into our attention.
Formaldehyde is a common environmental agent found in paint, cloth,
exhaust gas and many other medicinal and industrial products [19].
Formaldehyde exposure leads to formation of DNA/protein
crosslinks, a major mechanism of DNA damage.
The DNA/protein crosslinks have been used as a measure of dose
in drug delivery [20].
Formaldehyde, as a crosslinking agent, also reacts with thiol and
amino groups, leading to protein polymerization [21], [22].
Furthermore, methanol ingestion is an important public health
concern because of the selective actions of its toxic metabolites,
formaldehyde and formic acid, on the retina, the optic nerves
and the central nervous system (CNS) [23].
Illicit consumption of industrial methylated spirits can cause severe
and even fatal illness [24].
In the liver and retina, methanol is oxidized by alcohol
dehydrogenase, resulting in formaldehyde.
In semicarbazide-sensitive amine oxidase (SSAO)-mediated
pathogenesis of Alzheimer's disease, formaldehyde interacts
with B-amyloids and produces irreversibly cross-linked neurotoxic
amyloid-like complexes [21], [22], [25].
We have examined the role of formaldehyde
in misfolding of protein tau [26].
In particular, we investigated the toxicity of formaldehyde-induced
tau aggregates on human neuroblastoma cells (SH-SY5Y cell line)
and rat hippocampal cells [27].
The results showed that low concentrations (0.01 - 0.1%) of
formaldehyde are sufficient to induce formation of amyloid-like tau
aggregates, which can induce apoptosis of both SH-SY5Y
and hippocampal cells.
This may be significant to understand the mechanism of chronic
damage caused by methanol toxicity
and formaldehyde stress [18], [28].
However, we have still not known the mechanism of protein tau
aggregation in the presence of formaldehyde at low concentrations.
The present study concerns the characteristic of misfolding and
polymerization of extracellular and intracellular neuronal tau induced
by formaldehyde at low concentrations.....
Discussion
Clinical lethal dose of formaldehyde
Why did we investigate tau misfolding in the presence of
formaldehyde at low concentrations (0.01 - 0.1%)?
Methanol and ethanol are metabolized to formaldehyde and
acetaldehyde respectively in our hepatocytes
and some neural cells [36], [37].
Both formaldehyde and acetaldehyde can go through the
blood-brain barrier and cause some lesions to CNS,
especially our visual system [38].
Clinically, the lethal dose of formaldehyde for human beings is
about 0.08% in the circulation [39].
We have shown in the present study that formaldehyde can
significantly induce tau aggregation and polymerization at
concentrations even lower than 0.08%,
the clinical dose of toxicosis.
The same low concentration of formaldehyde did not induce
polymerization of BSA though theoretically it will cause any
protein to polymerize if the concentration is high enough.
On the other hand, although it is known that acetaldehyde is
acutely toxic and would covalently bind to proteins and other
macromolecules [40], in our AFM and SDS-PAGE studies
we did not observe tau polymerization caused by acetaldehyde at
the concentration range that we studied (0.1 - 1%)......
Tau aggregation relating to methanol and formaldehyde toxicity
Methanol is an ocular toxicant, which causes visual dysfunction and
often leads to blindness after acute exposure.
However, physiological and biochemical changes responsible
for the toxicity have not yet been well understood [28].
According to a recent report, humans are uniquely sensitive to the
toxicity of methanol, as they have limited capacity to oxidize and
detoxify formic acid.
Thus, the toxicity of methanol in humans is characterized by formic
acidaemia, metabolic acidosis, blindness or serious visual impairment,
mild central nervous system depression
and even death [23], [27], [28].
However, methanol toxicosis induces progressive complications
to CNS.
It is hard to explain the progressively chronic damage by local
accumulation of formic acid alone.
Therefore, the potential effect of formaldehyde on protein
misfolding may be significant, although formaldehyde remains
in the human body for only a short time.
In semicarbazide-sensitive amine oxidase (SSAO)-mediate
pathogenesis of Alzheimer's disease, formaldehyde interacts with
B-amyloids and produces irreversibly cross-linked neurotoxic
amyloid-like complexes [21], [22], [25].
Our studies showed that formaldehyde induced neuronal tau
to aggregate.
The amyloid-like tau induces apoptosis of SY5Y
and hippocampal cells [27].
In fact, chemically, formaldehyde reacts with thiol and
amino groups instantly,
resulting in subsequent misfolding of neuronal tau (Figure 11).
This suggests that amyloid-like tau is involved in methanol toxicosis,
especially the damage of neurons and the resulted complications
after exposure to formaldehyde.
Although there have been many studies on methanol and
formaldehyde intoxication [23], [24], none of them has addressed
the contribution of protein misfolding to the pathological mechanism,
in particular the effect of formaldehyde on protein conformation
and polymerization.
Interestingly, neurofibrillary tangles have been found in brains of
chronic alcoholics possessing neuropathological signs
of thiamine-deficiency [40], [47].
This suggests that tau misfolding may be involved in the
alcohol-induced pathological pathway.
Khlistunova and his colleagues found that neuronal tau repeat domain
could aggregate in vivo and was toxic to neuronal cells.
The degree of tau aggregation and toxicity depends on the propensity
of the B-structure [2], [48].
In the present study, we have demonstrated that amyloid-like
intracellular tau aggregates could induce cell apoptosis, a similar result
as that obtained for extracellular amyloid or a-synuclein [49] -- [51].
This suggests that an enriched B-sheet structure is important to
amyloid-like protein aggregation and neurotoxicity.
In our experiments, a low concentration of formaldehyde induced
both extracellular and intracellular tau proteins to aggregate into
cell-toxic amyloid-like granular aggregates [27].
It appears to provide a new mechanism for triggers of tauopathies
in the formaldehyde toxicosis.....

Formaldehyde concentration was assessed in the brain,
cerebrospinal liquor, arterial and venous blood of intact animals
and following its intraarterial injections.
It is concluded that formaldehyde is capable of penetrating
through the blood-brain barrier, with the degree of permeability

This lengthy review features in detail two quite different, revolutionary

It is indicative of our times that the CL Nie et al. study, 2007

Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a

(2007) Formic Acid, a Novel Metabolite of Chronic Ethanol
Abuse, Causes Neurotoxicity, Which Is Prevented by Folic Acid
Alcoholism: Clinical and Experimental Research 31 (12), 2114-2120.
doi:10.1111/j.1530-0277.2007.00541.x
Abstract
Background:
Methanol is endogenously formed in the brain and is present as a
congener in most alcoholic beverages.
Because ethanol is preferentially metabolized over methanol (MeOH)
by alcohol dehydrogenase, it is not surprising that MeOH
accumulates in the alcohol-abusing population.
This suggests that the alcohol-drinking population will have higher
levels of MeOH's neurotoxic metabolite, formic acid (FA).
FA elimination is mediated by folic acid.
Neurotoxicity is a common result of chronic alcoholism.
This study shows for the first time that FA,
found in chronic alcoholics, is neurotoxic
and this toxicity can be mitigated by folic acid administration.
Objective:
To determine if FA levels are higher in the alcohol-drinking
population and to assess its neurotoxicity in organotypic
hippocampal rat brain slice cultures.
Methods:
Serum and CSF FA was measured in samples from both ethanol
abusing and control patients, who presented to a hospital emergency
department. [ CSF = Cerebral Spinal Fluid ]
FA's neurotoxicity and its reversibility by folic acid were assessed
using organotypic rat brain hippocampal slice cultures using clinically
relevant concentrations.
Results:
Serum FA levels in the alcoholics
(mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls
(mean ± SE: 0.154 +- 0.009 mmol/l, n = 82) (p < n =" 20),">0.15 mmol/l in CSF of 3 of the 4 alcoholic cases.
Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours
to the rat brain slice cultures caused neuronal death as measured by
propidium iodide staining.
When folic acid (1 umol/l) was added with the FA,
neuronal death was prevented. [ umol = micromole ]
Conclusions:
Formic acid may be a significant factor in the neurotoxicity of
ethanol abuse.
This neurotoxicity can be mitigated by folic acid administration
at a clinically relevant dose.

NEUROTOXICITY AND BRAIN damage are common
concomitants findings of chronic alcoholism
(Carlen and Wilkinson, 1987; Carlen et al., 1981; Harper,
2007).
The cause of ethanol-induced neurotoxicity is still unclear.
We present here a novel hypothesis for neurotoxicity:
increased formic acid (FA) levels produced from methanol
(MeOH), whose catabolism is blocked by ethanol.
Axelrod and Daly (1965) demonstrated the endogenous formation
of MeOH from S-adenosylmethionine (SAM) in the pituitary
glands of humans and various other mammalian species.
Presence of MeOH in the breath of human subjects was
reported by Ericksen and Kulkarni (1963).
Most alcoholic beverages also have a small amount of MeOH
as a congener (Sprung et al., 1988).
As ethanol (EtOH) has a higher affinity for
alcohol dehydrogenase (ADH) than MeOH,
EtOH is preferentially metabolized (Mani et al., 1970).
As a result, MeOH accumulation from endogenously produced
MeOH, and/or, that consumed as part of an alcoholic beverage,
has been reported in concentrations up to 2 mmol/l in heavy
drinkers (Majchrowicz and Mendelson, 1971).
Toxicity resulting from MeOH consumption is extensively
documented in both humans and animals and has been
attributed to its metabolite, FA (Benton and Calhoun, 1952;
Roe, 1946, 1955; Wood, 1912; Wood and Buller, 1904).
The rate of formate oxidation and elimination is dependent on
adequate levels of hepatic folic acid, particularly hepatic
tetrahydrofolate (THF)
(Johlin et al., 1987; Tephly and McMartin, 1974).
Significantly higher formate levels were obtained when
folate-deficient animals were exposed to MeOH as compared
with folate-sufficient animals (Lee et al., 1994;
McMartin et al., 1975; Noker et al., 1980).
To understand ethanol's toxicity, one must consider FA
produced from MeOH, and its elimination mediated by folic acid.
We postulate that in the chronically drinking patient,
we will find higher levels of FA than in the nondrinking population,
and that formate is neurotoxic.
We also hypothesize that treatment with folic acid, which is a
critical factor in the catabolism of FA, can prevent or
diminish FA neurotoxicity.
METHODS
Patient Samples
During our study period of 4 months, 23 patients whose serum
showed the presence of both ethanol and trace amounts
(<2 n =" 82)" n =" 20)" n =" 7" nm =" nanometer" p =" NS" nd =" not" control =" no" acid =" 1" p =" NS"> *OH + Fe,3+ + OH,-
HCO2,- + *OH --> *CO2,- + H2O
*CO2,- + O2 --> CO2 + *O2,-
Chance has shown that formate can be metabolized by the
catalase-peroxidative system (Chance, 1950).
When anti-oxidants are depleted, increased ROS are formed
(Treichel et al., 2004).
Formic acid-induced cell damage has been attributed
to the generation of the cytotoxic ROS species.
FA disrupts mitochondrial electron transport and energy production
by inhibiting cytochrome oxidase activity (Nicholls, 1975, 1976;
Sharpe et al., 1982)
and causes cell death by increased production of cytotoxic ROS
secondary to the blockade of the electron transport chain
(Reed and Savage, 1995).
Formyl group (CHO) is transferred to THF
resulting in the formation of carbon dioxide and water
Makar et al., 1990; Medinsky et al., 1997).
Our organotypic brain slice studies suggest that there is a
dose and time relationship between FA and neuronal cell death.
FA levels achieved in the blood of the alcohol drinking
population can cause neuronal cell death.
The FA concentrations we used in our studies are representative
and were achieved in 2 of the 4 patients in whom we had sequential
samples.
It is remarkable that neuronal cell death could be prevented
by folic acid, although the mechanism of this protection is unknown.
There is a large body of literature relating folic acid deficiency
to neural tube defect, but, there are no references
relating low levels of FA to neurotoxicity.
There are a few studies relating FA and mitochondrial inhibition,
with MeOH intoxication and retinal damage
(Seme et al., 1999, 2001).
Another study demonstrated toxic effects of high concentrations
of formate in dissociated primary mouse neural cell cultures
(Dorman et al., 1993).
The concentration of formate that resulted
in 50% lactate dehydrogenase leakage after an 8-hour incubation
was estimated to be 45 mmol/l.
The total intracellular ATP concentration was significantly
decreased following either 20 or 40 mmol/l FA
exposure for 8 hour.
This is consistent with the hypothesis that FA may inhibit
mitochondrial function resulting in decreased intracellular ATP
and formate-induced neurotoxicity.
Using organotypic hippocampal slices, which preserve neuronal
circuitry and are easily accessible for experimental manipulations
(Stoppini et al., 1991),
our group has previously shown that
free radical overproduction in hippocampal pyramidal neurons
during ischemia/reoxygenation
depended on the activation of glutamate receptors,
and was associated with elevations of intracellular calcium.
Mitochondria are thought to be the principal source of
glutamate-mediated, calcium-dependent free radical production
in cultured cortical neurons
(Dugan et al., 1995; Reynolds and Hastings, 1995).
Although we did not investigate FA levels below 1 mmol/l,
it is conceivable that a continuous exposure to low,
but, above normal levels (>0.15 mmol/l), may also be cytotoxic
and may be part of the pathology of alcohol-related
organ damage (Jiang et al., 2003)
including the fetal alcohol spectrum disorder.
CONCLUSION
Our studies, for the first time, have shown that MeOH from
endogenous sources and from congeners present in alcoholic
beverages can lead to FA concentrations that are neurotoxic.
Therapeutic intervention with folic acid could be a significant
treatment modality in preventing FA mediated cytotoxicity,
especially neurotoxicity, in alcoholics.

Brief Summary:
Methanol in small amounts is present along with ethanol in beverage
alcohol.
[Murray: and about the same amounts from aspartame diet sodas]
The body's natural enzymes preferentially metabolize ethanol while
methanol breaks down into highly neurotoxic Formic Acid.
Use of high levels of Folic Acid was found to inhibit brain damage
caused by the methanol.
The use of Folic Acid during pregnancy has been recommended
for several years to prevent neural tube defects.
However, this study indicates that even higher levels of Folic Acid
can be very beneficial to the developing baby, particularly where
alcohol exposure is a factor.
Folic Acid is mandated as an additive to all flour sold in Canada.
The debate has begun on its required addition to all beverage
alcohol to help mitigate damage caused to both infants and adults.
Formic Acid in the Drinking patient and the expectant mother

Abstract
Methanol is produced endogenously in the pituitary glands of humans
and is present as a congener in almost all alcoholic beverages.
Ethanol and methanol are both bio-transformed by alcohol
dehydrogenase; however, ethanol has greater affinity for the enzyme.
Since ethanol is preferentially metabolized by the enzyme, it is not
surprising that trace amounts of methanol, most likely originating from
both sources, have been reported in the blood of people
who drink alcohol.
Toxicity resulting from methanol is very well documented
in both humans and animals and is attributed to its toxic metabolite
formic acid.
To understand ethanol toxicity
and Fetal Alcohol Spectrum Disorders, it is important to consider
methanol and its metabolite, formic acid, as
potential contributors to the toxic effects of alcohol.
Accumulation of methanol suggests that alcohol-drinking
population should have higher than baseline levels of formic acid.
Our preliminary studies do indeed show this.
Chronic low-level exposure to methanol has been suggested to
impair human visual functions.
Formic acid is known to be toxic to the optic nerve.
Ophthalmological abnormalities are a common finding in children
whose mothers used alcohol during pregnancy.
Formic acid, a low molecular weight substance, either crosses the
placenta or may be formed in-situ from the water soluble methanol
that crosses the placenta.
Embryo toxicity from formic acid has been reported
in an animal model.
To assess neurotoxicity we applied low doses of formic acid
to rat brain hippocampal slice cultures.
We observed neuronal death with a time and dose response.
Formic acid requires folic acid as a cofactor for its elimination.
Animal studies have shown that when folate levels are low, the
elimination of formic acid is slower and formate levels are elevated.
When folic acid was added along with the formic acid
to the brain slice cultures, neuronal death was prevented.
Therefore, folate deficient chronic drinkers may be at higher risk of
organ damage.
Women who are folic acid deficient and consume alcohol may have
higher levels of formic acid and should they become pregnant,
their fetus may be at risk.
To our knowledge low level chronic exposure to formic acid and its
relationship to folic acid in men or women who drink alcohol has
never been studied.
Our hypothesis is that the continuous exposure to low levels of
formic acid is toxic to the fetus and may be part of the etiology of
Fetal Alcohol Spectrum Disorders.

eyelid contact dermatitis by formaldehyde from aspartame,
AM Hill & DV Belsito, Nov 2003: Murray 4.4.4 rmforall [150 KB]
[ Extracts ]
McMartin, KE et al 1979, put 3,000 mg/kg methanol in the
stomachs of small monkeys and, 18 hours later found accumulation
of formate in liver, kidney, optic nerve, cerebrum, and midbrain
in 2 of three monkeys.
Biochemical Pharmcacology 1979: 28; 645-649.
Lack of a role for formaldehyde in methanol poisoning in the monkey.

and Thomas R. Tephly kmcmar@lsuhsc.edu;

K.E. McMartin and T.R. Tephly, authors of many pro-aspartame
studies, in Biochemical Pharmacology (1979) remarked,
"It is now generally accepted
that the toxicity of methanol is due to the formation of toxic
metabolites, either formaldehyde or formic acid."
They put damage doses of methanol into the stomachs
of three monkeys,
and, using insensitive tests, found no formaldehyde in many tissues --
except for a single datum in the midbrain,
1.5 times their detection limit.
They did report widespread accumulation of formic acid
in five tissues.
The use of inadequate tests is common in industry research that is
funded to claim the safety of profitable toxins.
Since then, industry scientists have been very wary of doing studies
on primates, which all too easily show the dangers to humans.
"Abstract [ not given in PubMed ]:
[ My briefer comments are in square brackets. ]
Methanol was administered [ by nasogastric tube ] either to untreated
cynomolgus monkeys [ 2-3.5 kg ] or to a folate-deficient cynomolgus
monkey which exhibits exceptional sensitivity to the toxic effects of
methanol.
Marked formic acid accumulation in the blood and in body fluids and
tissues was observed.
No formaldehyde accumulation was observed in the blood and no
formaldehyde was detected in the urine, cerebrospinal fluid, vitreous
humor, liver, kidney, optic nerve, and brain in these monkeys at a
time when marked metabolic acidosis and other characteristics of
methanol poisoning were observed.
Following intravenous infusion into the monkey, formaldehyde was
rapidly eliminated from the blood with a half-life of about 1.5 min
and formic acid levels promptly increased in the blood.
Since formic acid accumulation accounted for the metabolic acidosis
and since ocular toxicity essentially identical to that produced in
methanol poisoning has been described after formate treatment,
the predominant role of formic acid as the major metabolic agent
for methanol toxicity is certified.
Also, results suggest that formaldehyde is not a major factor in the
toxic syndrome produced by methanol in the monkey."
"It is now generally accepted that the toxicity of methanol is due to
the formation of toxic metabolites (1,2),
either formaldehyde or formic acid."
So, this is an acute toxicity study, with little relevance for chronic
long-term, low-level exposure.
Monkeys, like people, are susceptible to methanol toxicity.
This team cites their six previous methanol in monkey studies,
from 1975 to 1977.
The report is difficult to understand, since the three monkeys were
treated differently, and different assays were used.
For the methanol sensitive, folate-deficient monkey A, the assay
used was the chromatropic acid method,
with a detection limit of .025 mmol/L.
None of the five tissues showed any formaldehyde with this assay,
except the midbrain, 0.14 mmol/kg wet weight tissue
[ units converted from their 0.14 micromole/gm -- just
1.5 times the detection limit of .09 mmol/kg wet tissue weight
(given on p. 648).
[ Since 1 kg of water is 1 L, 1 mmol/kg is equivalent to 1 mmol/L. ]
Meanwhile, in the methanol sensitive, folate-deficient monkey A,
the blood formate level rose by 18 hours from 0.18 to 10.02 mEq/L.
[ I assume that a mEq is equivalent to a mmol -- let me know
if I'm wrong. ]
The formate detection limits for the assays were not given
in this report.
The formate level in the vitreous humor of the eye of monkey A
was 7.90 mEq/L.
It is well known that formate is extremely damaging to the eye.
For unexplained reasons, formate levels in the five tissues and
cerebrospinal fluid were not measured in the methanol sensitive,
folate-deficient monkey A.,
in the cerebrospinal fluid of monkey B,
or in the optic nerve of monkey C.
Formaldehyde was not measured in the optic nerve of Monkey A.
The kidney formate level for monkey B was 6.33
and for C was only 0.44,
with no comment or explanation given.
The experiment seems arbitrary, capricious, and erratic.
For monkey A, after 18 hours, the urine formaldehyde level was
below detection level, while urine formate was 115.80 mEq/L -- so
much of the formaldehyde had been converted into formic acid,
another cumulative, potent toxin.
"In the presence of high formate values and definitive evidence of
toxicity in methanol-poisoned monkeys, no measurable formaldehyde
was found in the body tissues that were tested."
It is reasonable to surmise that more sensitive assays would have found
formaldehyde and formate bound to and reacted with a variety of cellular
substances in all tissues -- just as the 1998 Trocho study confirmed.
(Appendix E)
Monkeys B and C were normal, not extra vulnerable to methanol,
and were given 3,000 mg/kg methanol, and samples taken at 18 hr.
Formaldehyde was detected only in the blood of Monkey B,
while formate was found in 8 and 10, respectively,
of the 10 fluid and tissue samples in Monkeys B and C.
For instance, the lowest value of formate, except for zero-time blood,
for each monkey was in the midbrain, 2.16 mmol/kg for Monkey B
(24 times the detection limit for the chromatropic acid method)
and 1.02 mmol/kg (1.3 times the detection for the dimedon method)
for Monkey C.
This shows accumulation of formate in liver, kidney, optic nerve,
cerebrum, and midbrain.
"Thus, whereas one can associate formate intimately with ocular
toxicity in the monkey, no association of formaldehyde with ocular
toxicity can be made at this time.
It is not possible to completely eliminate formaldehyde as a toxic
intermediate because formaldehyde could be formed slowly within
cells and interfere with normal cellular function without ever obtaining
levels that were detectable in body fluids..."

The toxicity of methanol.
Tephly TR.
Department of Pharmacology, University of Iowa, Iowa City 52242.
"Abstract:
Methanol toxicity in humans and monkeys is characterized by a latent
period of many hours followed by a metabolic acidosis
and ocular toxicity.
This is not observed in most lower animals.
The metabolic acidosis and blindness is apparently due to
formic acid accumulation in humans and monkeys,
a feature not seen in lower animals.
The accumulation of formate is due to a deficiency in formate
metabolism which is, in turn, related, in part,
to low hepatic tetrahydrofolate (H4 folate).
An excellent correlation between hepatic H4 folate and
formate oxidation rates has been shown within and across species.
Thus, humans and monkeys possess low hepatic H4 folate levels,
low rates of formate oxidation and accumulation of formate
after methanol.
Formate, itself, produces blindness in monkeys in the absence of
metabolic acidosis.
In addition to low hepatic H4 folate concentrations, monkeys and
humans also have low hepatic 10-formyl H4 folate dehydrogenase
levels, the enzyme which is the ultimate catalyst for conversion of
formate to carbon dioxide.
This review presents the basis for the role of folic acid-dependent
reactions in the regulation of methanol toxicity.

" Recent studies have shown that neurodegeneration

" Both formaldehyde and acetaldehyde can go through the
blood-brain barrier and cause some lesions to CNS,
especially our visual system [38].
Clinically, the lethal dose of formaldehyde for human beings is
about 0.08% in the circulation [39].
We have shown in the present study that formaldehyde can
significantly induce tau aggregation and polymerization at
concentrations even lower than 0.08%,
the clinical dose of toxicosis. "
" Formaldehyde exposure leads to formation of DNA/protein
crosslinks, a major mechanism of DNA damage.
The DNA/protein crosslinks have been used as a measure
of dose in drug delivery [20].
Formaldehyde, as a crosslinking agent, also reacts with
thiol and amino groups, leading to protein polymerization [21], [22].
Furthermore, methanol ingestion is an important public health
concern because of the selective actions of its toxic metabolites,
formaldehyde and formic acid, on the retina, the optic nerves
and the central nervous system (CNS) [23].
Illicit consumption of industrial methylated spirits can cause severe
and even fatal illness [24].
In the liver and retina, methanol is oxidized by alcohol
dehydrogenase, resulting in formaldehyde.
In semicarbazide-sensitive amine oxidase (SSAO)-mediated
pathogenesis of Alzheimer's disease, formaldehyde interacts
with B-amyloids and produces irreversibly cross-linked neurotoxic
amyloid-like complexes [21], [22], [25].
We have examined the role of formaldehyde in misfolding
of protein tau [26].
In particular, we investigated the toxicity of formaldehyde-induced
tau aggregates on human neuroblastoma cells (SH-SY5Y cell line)
and rat hippocampal cells [27].
The results showed that low concentrations (0.01 - 0.1%) of
formaldehyde are sufficient to induce formation of amyloid-like tau
aggregates, which can induce apoptosis of both SH-SY5Y
and hippocampal cells.
This may be significant to understand the mechanism of chronic
damage caused by methanol toxicity
and formaldehyde stress [18], [28].
However, we have still not known the mechanism of protein tau
aggregation in the presence of formaldehyde at low concentrations.
The present study concerns the characteristic of misfolding and
polymerization of extracellular and intracellular neuronal tau induced
by formaldehyde at low concentrations. "

Abstract
Recent studies have shown that neurodegeneration is closely
related to misfolding and aggregation of neuronal tau.
Our previous results show that neuronal tau aggregates in
formaldehyde solution and that aggregated tau induces apoptosis
of SH-SY5Y and hippocampal cells.
In the present study, based on atomic force microscopy (AFM)
observation, we have found that formaldehyde at low concentrations
induces tau polymerization whilst acetaldehyde does not.
Neuronal tau misfolds and aggregates into globular-like polymers
in 0.01 - 0.1% formaldehyde solutions.
Apart from globular-like aggregation, no fibril-like polymerization
was observed when the protein was incubated with formaldehyde
for 15 days.
SDS-PAGE results also exhibit tau polymerizing in the presence
of formaldehyde.
Under the same experimental conditions, polymerization of bovine
serum albumin (BSA) or a-synuclein was not markedly detected.
Kinetic study shows that tau significantly misfolds and polymerizes
in 60 minutes in 0.1% formaldehyde solution.
However, presence of 10% methanol prevents protein tau from
polymerization.
This suggests that formaldehyde polymerization is involved in tau
aggregation.
Such aggregation process is probably linked to the tau's special
"worm-like" structure, which leaves the e-amino groups of Lys
and thiol groups of Cys exposed to the exterior.
Such a structure can easily bond to formaldehyde molecules
in vitro and in vivo.
Polymerizing of formaldehyde itself results in aggregation of
protein tau.
Immunocytochemistry and thioflavin S staining of both endogenous
and exogenous tau in the presence of formaldehyde at low
concentrations in the cell culture have shown that formaldehyde can
induce tau into amyloid-like aggregates in vivo during apoptosis.
The significant protein tau aggregation induced by formaldehyde
and the severe toxicity of the aggregated tau to neural cells may
suggest that toxicity of methanol and formaldehyde ingestion is
related to tau misfolding and aggregation.

Introduction
Neuronal tau is an important protein in promoting and stabilizing the
microtubule system involved in cellular transport
and neuronal morphogenesis.
The tau molecule can be subdivided into an amino-terminal domain
that projects from the microtubule surface and a carboxy-terminal
microtubule-binding domain.
The discovery that incubation of bacterially expressed human tau
with sulphated glycosaminoglycans leads to bulk assembly of tau
filaments [1], making it possible to obtain structural information [2].
By using circular dichroism measurement, Schweer et al. have found
that protein tau lacks secondary structures and is considered in a
"worm-like" conformation with a high flexibility [3].
Therefore, the side-chains of amino acids such as Lys, Cys, Thr
and Ser are mostly exposed and vulnerable to chemical modification.
Recently, many laboratories have found that misfolding and
aggregation of protein tau are involved in neurodegeneration
[2], [4] - [6].
Protein tau has been found as the major component of paired
helical filaments in neurofibrillary tangles in the brains of Alzheimer's
patients, where abnormal hyper-phosphorylation induces tau to
misfold and form the paired helical filaments,
depositing in the cytoplasm of neurons [7] - [10].
Recently, a great deal of evidence has demonstrated that oxidation
and glycation stresses are key causal factors of neuronal degenerative
diseases [11] - [13].
Both of them inevitably produce a variety of unsaturated carbonyls
as intermediates, like malondialdehyde and 4-hydroxynonenal,
which usually cause carbonyl-amino crosslinking and lead to
accumulation of irreversible changes (like lipofuscin) related to
various neurodegenerative diseases in particular [14] - [16].
Such carbonyl stress-related reactions (carbonylation) can form
unstable and reversible 1:1 amino-carbonyl (Shiff's base)
compounds at an early stage of protein modification [16], [17].
Carbonylation binds and blocks a-/e- amino groups,
and results in changes in charge and conformation of a protein.
In order to investigate the relationship between carbonylation and
protein tau misfolding, the basic and simplest carbonyl compound
formaldehyde [18] has come into our attention.
Formaldehyde is a common environmental agent found in paint, cloth,
exhaust gas and many other medicinal and industrial products [19].
Formaldehyde exposure leads to formation of DNA/protein
crosslinks, a major mechanism of DNA damage.
The DNA/protein crosslinks have been used as a measure of dose
in drug delivery [20].
Formaldehyde, as a crosslinking agent, also reacts with thiol and
amino groups, leading to protein polymerization [21], [22].
Furthermore, methanol ingestion is an important public health
concern because of the selective actions of its toxic metabolites,
formaldehyde and formic acid, on the retina, the optic nerves
and the central nervous system (CNS) [23].
Illicit consumption of industrial methylated spirits can cause severe
and even fatal illness [24].
In the liver and retina, methanol is oxidized by alcohol
dehydrogenase, resulting in formaldehyde.
In semicarbazide-sensitive amine oxidase (SSAO)-mediated
pathogenesis of Alzheimer's disease, formaldehyde interacts
with B-amyloids and produces irreversibly cross-linked neurotoxic
amyloid-like complexes [21], [22], [25].
We have examined the role of formaldehyde
in misfolding of protein tau [26].
In particular, we investigated the toxicity of formaldehyde-induced
tau aggregates on human neuroblastoma cells (SH-SY5Y cell line)
and rat hippocampal cells [27].
The results showed that low concentrations (0.01 - 0.1%) of
formaldehyde are sufficient to induce formation of amyloid-like tau
aggregates, which can induce apoptosis of both SH-SY5Y
and hippocampal cells.
This may be significant to understand the mechanism of chronic
damage caused by methanol toxicity
and formaldehyde stress [18], [28].
However, we have still not known the mechanism of protein tau
aggregation in the presence of formaldehyde at low concentrations.
The present study concerns the characteristic of misfolding and
polymerization of extracellular and intracellular neuronal tau induced
by formaldehyde at low concentrations.....
Discussion
Clinical lethal dose of formaldehyde
Why did we investigate tau misfolding in the presence of
formaldehyde at low concentrations (0.01 - 0.1%)?
Methanol and ethanol are metabolized to formaldehyde and
acetaldehyde respectively in our hepatocytes
and some neural cells [36], [37].
Both formaldehyde and acetaldehyde can go through the
blood-brain barrier and cause some lesions to CNS,
especially our visual system [38].
Clinically, the lethal dose of formaldehyde for human beings is
about 0.08% in the circulation [39].
We have shown in the present study that formaldehyde can
significantly induce tau aggregation and polymerization at
concentrations even lower than 0.08%,
the clinical dose of toxicosis.
The same low concentration of formaldehyde did not induce
polymerization of BSA though theoretically it will cause any
protein to polymerize if the concentration is high enough.
On the other hand, although it is known that acetaldehyde is
acutely toxic and would covalently bind to proteins and other
macromolecules [40], in our AFM and SDS-PAGE studies
we did not observe tau polymerization caused by acetaldehyde at
the concentration range that we studied (0.1 - 1%)......
Tau aggregation relating to methanol and formaldehyde toxicity
Methanol is an ocular toxicant, which causes visual dysfunction and
often leads to blindness after acute exposure.
However, physiological and biochemical changes responsible
for the toxicity have not yet been well understood [28].
According to a recent report, humans are uniquely sensitive to the
toxicity of methanol, as they have limited capacity to oxidize and
detoxify formic acid.
Thus, the toxicity of methanol in humans is characterized by formic
acidaemia, metabolic acidosis, blindness or serious visual impairment,
mild central nervous system depression
and even death [23], [27], [28].
However, methanol toxicosis induces progressive complications
to CNS.
It is hard to explain the progressively chronic damage by local
accumulation of formic acid alone.
Therefore, the potential effect of formaldehyde on protein
misfolding may be significant, although formaldehyde remains
in the human body for only a short time.
In semicarbazide-sensitive amine oxidase (SSAO)-mediate
pathogenesis of Alzheimer's disease, formaldehyde interacts with
B-amyloids and produces irreversibly cross-linked neurotoxic
amyloid-like complexes [21], [22], [25].
Our studies showed that formaldehyde induced neuronal tau
to aggregate.
The amyloid-like tau induces apoptosis of SY5Y
and hippocampal cells [27].
In fact, chemically, formaldehyde reacts with thiol and
amino groups instantly,
resulting in subsequent misfolding of neuronal tau (Figure 11).
This suggests that amyloid-like tau is involved in methanol toxicosis,
especially the damage of neurons and the resulted complications
after exposure to formaldehyde.
Although there have been many studies on methanol and
formaldehyde intoxication [23], [24], none of them has addressed
the contribution of protein misfolding to the pathological mechanism,
in particular the effect of formaldehyde on protein conformation
and polymerization.
Interestingly, neurofibrillary tangles have been found in brains of
chronic alcoholics possessing neuropathological signs
of thiamine-deficiency [40], [47].
This suggests that tau misfolding may be involved in the
alcohol-induced pathological pathway.
Khlistunova and his colleagues found that neuronal tau repeat domain
could aggregate in vivo and was toxic to neuronal cells.
The degree of tau aggregation and toxicity depends on the propensity
of the B-structure [2], [48].
In the present study, we have demonstrated that amyloid-like
intracellular tau aggregates could induce cell apoptosis, a similar result
as that obtained for extracellular amyloid or a-synuclein [49] -- [51].
This suggests that an enriched B-sheet structure is important to
amyloid-like protein aggregation and neurotoxicity.
In our experiments, a low concentration of formaldehyde induced
both extracellular and intracellular tau proteins to aggregate into
cell-toxic amyloid-like granular aggregates [27].
It appears to provide a new mechanism for triggers of tauopathies
in the formaldehyde toxicosis.....

Formaldehyde concentration was assessed in the brain,

It is concluded that formaldehyde is capable of penetrating
through the blood-brain barrier, with the degree of permeability
depending on blood formaldehyde concentration.
The distribution of formaldehyde in the blood-brain-cerebrospinal

Hawaii House of Representatives H.C.R. No. 132,
Twenty-fourth Legislature,
State of Hawaii -- House Concurrent Resolution
Requesting the Director of Health to form a work group to explore
the need to ban or better label products containing the artificial
sweetener aspartame.
WHEREAS, discovered in 1965, aspartame was first approved in the
United States in 1981 and is one of the most widely used artificial
sweeteners; and
WHEREAS, when metabolized by the body, aspartame is broken
down into two common amino acids, aspartic acid and phenylalanine,
and a small amount of a third substance, methanol; and
[ Note: the aspartame molecule becomes equal numbers of aspartic
acid, phenylalanine, and methanol molecules (which although light weight,
are more chemically active by far, being turned quickly into nearly the
same number of molecules of formaldehyde and then formic acid,
enough to have toxic effects in every cell in the body by binding with
and impairing DNA, RNA, and protein molecules. ]
WHEREAS, these three substances occur in similar or greater amounts
in common foods; and
[ Note: methanol and formaldehyde are also supplied by dark wines
and liquors (the major cause of "morning after" hangovers), tobacco and
wood smoke, fumes from faulty furnaces, heaters and stoves, many fruits
and vegetables (when heated in canning, fermented, or degraded by
colonic bacteria), mobile homes and RVs, particleboard, new buildings
new cars, carpets, drapes, and furniture, mortuaries, medical training
and research, many cleaners and disinfectants, many personal care
products ranging from leather to hair dyes, and more, including many
Asian foods. ]
WHEREAS, aspartame continues to be the subject of strong public
controversy regarding its safety; and
WHEREAS, some studies have recommended further investigation into
the possible connection between aspartame and diseases such as brain
tumors, brain lesions, and lymphoma; and
[ Note: the range of symptoms also includes headache, fatigue, poor
memory, irritability, lassitude, mania, anxiety, depression, "brain fog",
insomnia, dizziness, many body pains and muscle cramps, restless legs,
interstitial cystitis, eye and vision problems, tinnitus, dry eyes and
mouth,
skin rashes, diarrhea or constipation, partial paralysis (often confused as
MS), ideopathic seizures, weight gain or loss, blood sugar swings,
craving and addiction, impaired fertility and pregnancy, "spontaneous"
abortion, premature birth, low birth weight, birth defects, sudden infant
death syndrome, autism, and early diabetes -- this dazzling litany of
outcomes is the natural result of chronic, long-term, low-level exposure
to formaldehyde and formic acid. Naturally, there are countless
interactions with other drugs and toxins, as well as major and complex
individual genetic variations.
Cheap, safe folic acid protects against formaldehyde toxicity in most
people. ]
WHEREAS, some human and animal studies have found adverse effects
and some have found no adverse effects; and [ Note: almost all industry
and vested interest funded research claims no evidence of problems,
while the opposite is found by independent teams. ]
WHEREAS, while there have been a number of studies on the effects
of aspartame on people, there is a great deal of argument by both
proponents and opponents on the methods used in the testing and
whether accurate representations of the consequences of average
consumption by people have been achieved by these studies; and
Note: a major need is to focus on the effects for long-term heavy users,
above 6 12-oz cans daily diet drink, from vulnerable groups like fetus,
infants, kids, teens, students, difficult critical jobs like police, pilots,
military, and nuclear plant operators, pregnant women, seniors, obese,
diabetic, depressed, violent criminal, cancer, and, especially,
over-worked PR agents lavishly funded to defend aspartame as,
"the most tested food additive in history".
WHEREAS, the Internet has become a tool for many to spread and
promote the opinion they adhere to as fact whether it is that aspartame
is a neurotoxin derived from toxic sludge or it is a harmless product
enabling a healthy lifestyle; and
WHEREAS, while many may find that the simple answer to the
problem is to not purchase or use any product containing aspartame
in it, there are those who maintain that some products do not
specifically list aspartame as an ingredient, rather it is hidden under
the label of "natural flavors"; now, therefore,
BE IT RESOLVED by the House of Representatives of the
Twenty-fourth Legislature of the State of Hawaii, Regular Session
of 2008, the Senate concurring, that the Director of Health is
requested to form a work group to explore the need to ban or

appointed by the Speaker of the House of Representatives;
(2) One member of the Senate
appointed by the President of the Senate;
(3) The Director of Health or the director's designee;

[ Rich Murray comments: As a medical layman volunteer information
activist for aspartame and related toxicity issues since January 1999,
I note with appreciation the remarkable exponential progress on all
fronts, including a rapidly emerging consensus about the primary
importance of all toxicity challenges for our world.
This lengthy review features in detail two quite different, revolutionary
contributions, from Canada, and England and China.
It is indicative of our times that the CL Nie et al. study, 2007
appears in a free, open access journal-- indeed,
as all life and death information must.
Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a
30-page review as 3 pages a decade ago -- and such reviews
are archived forever in multiple collections, open via global search
engines to a billion Net citizens.
Perforce, and increasingly happily, all societal entities will have to
operate by high and shared voluntary universal standards
for the common good. ]

Abstract
Background:
Methanol is endogenously formed in the brain and is present as a
congener in most alcoholic beverages.
Because ethanol is preferentially metabolized over methanol (MeOH)
by alcohol dehydrogenase, it is not surprising that MeOH
accumulates in the alcohol-abusing population.
This suggests that the alcohol-drinking population will have higher
levels of MeOH's neurotoxic metabolite, formic acid (FA).
FA elimination is mediated by folic acid.
Neurotoxicity is a common result of chronic alcoholism.
This study shows for the first time that FA,
found in chronic alcoholics, is neurotoxic
and this toxicity can be mitigated by folic acid administration.
Objective:
To determine if FA levels are higher in the alcohol-drinking
population and to assess its neurotoxicity in organotypic
hippocampal rat brain slice cultures.
Methods:
Serum and CSF FA was measured in samples from both ethanol
abusing and control patients, who presented to a hospital emergency
department. [ CSF = Cerebral Spinal Fluid ]
FA's neurotoxicity and its reversibility by folic acid were assessed
using organotypic rat brain hippocampal slice cultures using clinically
relevant concentrations.
Results:
Serum FA levels in the alcoholics
(mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls
(mean ± SE: 0.154 +- 0.009 mmol/l, n = 82) (p < n =" 20),">0.15 mmol/l in CSF of 3 of the 4 alcoholic cases.
Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours
to the rat brain slice cultures caused neuronal death as measured by
propidium iodide staining.
When folic acid (1 umol/l) was added with the FA,
neuronal death was prevented. [ umol = micromole ]
Conclusions:
Formic acid may be a significant factor in the neurotoxicity of
ethanol abuse.
This neurotoxicity can be mitigated by folic acid administration
at a clinically relevant dose.

Hawaii House of Representatives H.C.R. No. 132,
Twenty-fourth Legislature,
State of Hawaii -- House Concurrent Resolution
Requesting the Director of Health to form a work group to explore
the need to ban or better label products containing the artificial
sweetener aspartame.
WHEREAS, discovered in 1965, aspartame was first approved in the
United States in 1981 and is one of the most widely used artificial
sweeteners; and
WHEREAS, when metabolized by the body, aspartame is broken
down into two common amino acids, aspartic acid and phenylalanine,
and a small amount of a third substance, methanol; and
[ Note: the aspartame molecule becomes equal numbers of aspartic
acid, phenylalanine, and methanol molecules (which although light weight,
are more chemically active by far, being turned quickly into nearly the
same number of molecules of formaldehyde and then formic acid,
enough to have toxic effects in every cell in the body by binding with
and impairing DNA, RNA, and protein molecules. ]
WHEREAS, these three substances occur in similar or greater amounts
in common foods; and
[ Note: methanol and formaldehyde are also supplied by dark wines
and liquors (the major cause of "morning after" hangovers), tobacco and
wood smoke, fumes from faulty furnaces, heaters and stoves, many fruits
and vegetables (when heated in canning, fermented, or degraded by
colonic bacteria), mobile homes and RVs, particleboard, new buildings
new cars, carpets, drapes, and furniture, mortuaries, medical training
and research, many cleaners and disinfectants, many personal care
products ranging from leather to hair dyes, and more, including many
Asian foods. ]
WHEREAS, aspartame continues to be the subject of strong public
controversy regarding its safety; and
WHEREAS, some studies have recommended further investigation into
the possible connection between aspartame and diseases such as brain
tumors, brain lesions, and lymphoma; and
[ Note: the range of symptoms also includes headache, fatigue, poor
memory, irritability, lassitude, mania, anxiety, depression, "brain fog",
insomnia, dizziness, many body pains and muscle cramps, restless legs,
interstitial cystitis, eye and vision problems, tinnitus, dry eyes and
mouth,
skin rashes, diarrhea or constipation, partial paralysis (often confused as
MS), ideopathic seizures, weight gain or loss, blood sugar swings,
craving and addiction, impaired fertility and pregnancy, "spontaneous"
abortion, premature birth, low birth weight, birth defects, sudden infant
death syndrome, autism, and early diabetes -- this dazzling litany of
outcomes is the natural result of chronic, long-term, low-level exposure
to formaldehyde and formic acid. Naturally, there are countless
interactions with other drugs and toxins, as well as major and complex
individual genetic variations.
Cheap, safe folic acid protects against formaldehyde toxicity in most
people. ]
WHEREAS, some human and animal studies have found adverse effects
and some have found no adverse effects; and [ Note: almost all industry
and vested interest funded research claims no evidence of problems,
while the opposite is found by independent teams. ]
WHEREAS, while there have been a number of studies on the effects
of aspartame on people, there is a great deal of argument by both
proponents and opponents on the methods used in the testing and
whether accurate representations of the consequences of average
consumption by people have been achieved by these studies; and
Note: a major need is to focus on the effects for long-term heavy users,
above 6 12-oz cans daily diet drink, from vulnerable groups like fetus,
infants, kids, teens, students, difficult critical jobs like police, pilots,
military, and nuclear plant operators, pregnant women, seniors, obese,
diabetic, depressed, violent criminal, cancer, and, especially,
over-worked PR agents lavishly funded to defend aspartame as,
"the most tested food additive in history".
WHEREAS, the Internet has become a tool for many to spread and
promote the opinion they adhere to as fact whether it is that aspartame
is a neurotoxin derived from toxic sludge or it is a harmless product
enabling a healthy lifestyle; and
WHEREAS, while many may find that the simple answer to the
problem is to not purchase or use any product containing aspartame
in it, there are those who maintain that some products do not
specifically list aspartame as an ingredient, rather it is hidden under
the label of "natural flavors"; now, therefore,
BE IT RESOLVED by the House of Representatives of the
Twenty-fourth Legislature of the State of Hawaii, Regular Session
of 2008, the Senate concurring, that the Director of Health is
requested to form a work group to explore the need to ban or
improve labeling for products containing the artificial sweetener
aspartame; and
BE IT FURTHER RESOLVED the members of the work group
should include:
(1) One member from the House of Representatives
appointed by the Speaker of the House of Representatives;
(2) One member of the Senate
appointed by the President of the Senate;
(3) The Director of Health or the director's designee;
(4) The President of the Calorie Control Council or the President's
designee; and [ the preminent aspartame lobby ]
(5) The President and Chief Executive Officer

(6) The President of the Hawaii Society of Naturopathic Physicians or a

(7) The Founder of Mission Possible International or a designee; and
(8) Two consumers appointed by the Director of Health; and
BE IT FURTHER RESOLVED the work group is requested to submit
a report of its findings, as well as any suggested legislation, to the
Legislature no later than 20 days prior to the convening of the
Regular Session of 2010; and

[ Rich Murray comments: As a medical layman volunteer information
activist for aspartame and related toxicity issues since January 1999,
I note with appreciation the remarkable exponential progress on all
fronts, including a rapidly emerging consensus about the primary
importance of all toxicity challenges for our world.
This lengthy review features in detail two quite different, revolutionary
contributions, from Canada, and England and China.
It is indicative of our times that the CL Nie et al. study, 2007
appears in a free, open access journal-- indeed,
as all life and death information must.
Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a
30-page review as 3 pages a decade ago -- and such reviews
are archived forever in multiple collections, open via global search
engines to a billion Net citizens.
Perforce, and increasingly happily, all societal entities will have to
operate by high and shared voluntary universal standards
for the common good. ]

Hawaii Senate Committee Will Consider Resolution on Aspartame
By Stephen Fox, 3/13/2008 10:49:31 AM
There is now a Hawaii Senate Resolution,
authored by Sen. Suzanne Chun Oakland, which requests the
Department of Health and National Academy of Sciences
to review existing reports and studies related to aspartame,
by funding source.
It resolves that given the enormous amount of evidence
that has been compiled concerning the neurodegenerative harm
it can cause, that the U.S. Food and Drug Administration
is requested to rescind approval of aspartame immediately
on a phase-out basis over six months to one year.
We are very pleased to note that this is the strongest legislative
document concerning aspartame ever presented anywhere
in the world.
On March 12, another resolution, HCR132, introduced by Rep.
Josh Green, M.D., Chairman of the House Committee on Health,
was approved by its first committee (Health),
and moves on to the next (Consumer Protection and Commerce).
This would set up a work group to explore the need to ban
or improve labeling containing aspartame.
It was again opposed by Dr. Chiyome Fukino, M.D.,
Director of the Health Department,
an appointee of Republican Governor Linda Lingle,
who opposed the House Bill to ban aspartame on the flawed basis
of an Ajinomoto-funded review study;
Ajinomoto is the world's largest manufacturer of Aspartame,
and another proven neurotoxic food additive,
Monosodium Glutamate.
Betty Martini, D. Hum, sent Dr. Fukino a detailed rebuttal
to this study, showing the links to Ajinomoto
and flawed industry research.
Dr. Fukino's opposition today, March 12 was surprisingly opposed
by Rep. Green, M.D., the only physician in the entire Hawaii
Legislature, in view of him having 'deferred' a prior bill to ban
aspartame outright, by statute.
Here is the rebuttal to the Ajinomoto Study, written by Mark Gold,
Founder, Aspartame Toxicity Information Center, New Hampshire:
http://www.holisticmed.com/aspartame/burdock/
Aspartame and Manufacturer-Funded Scientific Reviews
This flawed Ajinomoto-funded report,
which has been touted far and wide by aspartame manufacturers
and corporate hacks and lobbyists, shows how far the world's
largest aspartame manufacturer will go to deceive the public.
However, today, there is no doubt that Ajinomoto's
Board of Directors as well as the Board of Directors of
Coca Cola, Pepsi, Wrigley's Gum, and Merisant
(manufacturer of Equal) are extremely worried about these
late-breaking developments in Hawaii, which should also
encourage consumer protection activists all over the world
to contact their legislators and parliamentarians, asking them
to introduce similar legislation and Resolutions.
We cordially thank Senator Chun Oakland and Representative
Josh Green, M.D., for advancing our consumer protection initiative
as far as they have.
Text of Senate Resolution:
http://www.capitol.hawaii.gov/session2008/bills/SCR191_.pdf
Requesting the Hawaii Department of Health and
the National Academy of Sciences to review existing reports
and studies related to Aspartame, and Requesting the United States
Food and Drug Administration to Rescind Approval for
United States Markets,
carried by Hawaii Senator Suzanne Chun Oakland
Whereas, aspartame was originally developed as a drug to treat
peptic ulcers; and
Whereas, manufacturers state that aspartame is made up of
forty per cent aspartic acid, fifty percent phenylalanine,
and ten per cent methanol; and
Whereas, aspartic acid is a nonessential amino acid
that is used by the body to initiate apoptosis or cell death
in aging cells,
and that excess aspartic acid from aspartame consumption causes
apoptosis in health cells that can destroy healthy tissue,
especially in the brain; and
Whereas, phenylalanine is an essential amino acid found naturally
in protein but when isolated becomes neurotoxic, lowers the seizure
threshold, depletes serotonin -- triggering psychiatric and behavioral
problems -- and interacts with depressants and other drugs; and
Whereas, methanol is a severe metabolic poison classified as a
narcotic that converts to formaldehyde and formic acid,
and can embalm living tissue and damage DNA; and
Whereas, aspartame metabolites include formaldehyde,
a 'class A' carcinogen, and diketopiperazine, a brain tumor agent,
and formic acid, and
Whereas, in 1974, the United States Food and Drug Administration
approved aspartame as an artificial sweetener,
but asked its manufacturer Searle to hold back from selling it on the
market until further tests could be made with regards to its safety;
and
Whereas, scientific data revealed that there was a problem with
aspartame safety date and the United States Food and Drug
Administration withdrew its approval; and
Whereas, in 1975, the United States Food and Drug
Administration initiated an investigation into Searle's laboratory
practices and discovered fraud in scientific experiments as well as
manipulated data giving favorable results proving aspartame
to be safe; and
Whereas, the results of this investigation are included in
what is called 'The Bressler Report' by Jerome Bressler; and
[ http://dorway.com/dorwblog/?page_id=56

Whereas, in 1980, Dr. John Olney submitted scientific data to a
United States Food and Drug Administration Public Board of Inquiry
showing that aspartic acid, the excitotoxic ingredient in aspartame,
caused holes in the brains of mice; and
Whereas, Dr. John Olney stated that it warranted special emphasis
that excitotoxins act by an acute but silent mechanism, requiring
only a single exposure for CVO neurons to be quietly destroyed,
that clearly Searle failed to establish the safety of their product,
aspartame, for use in children's food, and that all age comparative
data support the following conclusions:
(1) orally administered excitotoxins destroy CVO neurons
at any age;
(2) immature animals are most vulnerable; and
(3) the toxic threshold increases only gradually between birth and
adulthood; and
Whereas, in 1980, the Public Board of Inquiry unanimously
voted against aspartame approval, but was overruled by a new
United States Food and Drug Administration Commissioner,
Dr. Arthur Hull Hayes, against the advice of Food and Drug
Administration scientific personnel and advisers; and
Whereas, the United States Food and Drug Administration
approved aspartame use in sodas, despite the fact that the
National Soft Drink Association argued vehemently against
aspartame in these quotes from their protest:
[ With their original name, The National Soft Drink Association, they
condemned aspartame on July 28, 1983 in a detailed critique:
http://dorway.com/dorwblog/?page_id=60 ]
* (1) "The present record does not contain data which
demonstrate that the use of APM in soft drinks will not result in the
adulteration of the beverages under Section 402(a)(3) of the
FDC Act 21 U.S.S. 342 (a)(3),
which provides that a food is adulterated if it contains, in whole
or in part, 'a decomposed substance
or it is otherwise unfit for food'�)";
(2) "An important decomposition product of aspartame,
aspartic acid, cannot be detected at all using TLC"�;
(3) "�G.D. Searle and Company has not demonstrated to a reasonable
certainty that the use of aspartame in soft drinks, without quantitative limitations, will not adversely affect human health as a result of the changes such use is likely to cause in brain chemistry and under certain reasonably anticipated conditions of use"; and
(4) "Specifically, Searle has not met its burdens under section
409 'to demonstrate that aspartame is safe and functional for use
in soft drinks.' Collectively, the extensive deficiencies in the stability studies conducted by Searle to demonstrate that aspartame and its degradation products are safe in soft drinks intended to be sold in the United States, render those studies inadequate and unreliable."�
Senate Congressional Record, May 7, 1985, S5507-5511: and
Whereas, the United States Food and Drug Administration
has compiled a list of ninety-two symptoms attributed to aspartame
consumption including four types of seizures, coma, and death; and
Whereas, the Ramazzini Studies by the European Foundation for Oncology in Italy conducted exhaustive studies over three years with thousands of rats, and proved aspartame to be a multipotential carcinogen, thus confirming the United States Food and Drug Administration's original findings;
and
Whereas, the United States Food and Drug Administration
admitted that aspartame caused cancer over two decades ago,
when the Administration's toxicologist, Dr. Adrian Gross, told
Congress at least one of Searle's studies:
"has established beyond any reasonable doubt that aspartame is
capable of inducing brain tumors in experimental animals and that
this predisposition of it is of extremely high significance". In view
of these indications that the cancer causing potential of aspartame
is a matter that had been established way beyond any reasonable
doubt, one can ask: What is the reason for the apparent refusal
by the FDA to invoke for this food additive the so-called Delaney
amendment to the Food, Drug, and Cosmetic act?
Given the cancer causing potential of aspartame, how would the
FDA justify its position that it views a certain amount of aspartame
as constituting an allowable daily intake or 'safe' level of it?
Is that position in effect not equivalent to setting a 'tolerance'
for this food additive and thus a violation of that law?
And if the FDA itself elects to violate the law,
who is left to protect the health of the public?"�
Congressional Record, August 1, 1985, SID835: 131: and
Whereas, aspartame is linked to sudden death, multiple sclerosis,
lupus, and many neurodegenerative diseases, as cited in may medical
texts, most notably: Aspartame Disease: An Ignored Epidemic,
by H.J. Roberts, M.D., and
Excitotoxins: the Taste that Kills, By Russell Blaylock, M.D., and
Whereas, on November 3, 1987, Dr. Louis Elsas told Congress:
"I am a pediatrician, a Professor of Pediatrics at Emory
and have spent twenty-five years in the biomedical sciences,
trying to prevent mental retardation and birth defect caused by excess
phenylalanine, and therein lies my basic concern, that aspartame is
in fact a well known neurotoxin and teratogen which, in some as yet
undefined dose, will irreversibly in the developing child or fetal brain, produce adverse effects." and
Whereas, there are tens of thousands of case histories and anecdotal
accounts from victims of aspartame poisoning who have come forward to make their case histories known; now, therefore,
BE IT RESOLVED by the Senate of the Twenty-Fourth Legislature
of the State of Hawaii, Regular Session of 2008,
the House of Representatives concurring,
that the Department of Health is requested to create,
within their existing budget,
an evidentiary repository accessible to the public for patients and
physicians to submit of the next year their cases involving victims
of aspartame poisoning; and
BE IT FURTHER RESOLVED that the Director of Health
is requested to report to the Legislature on the status of the
evidentiary repository during periodic interim meetings
with the Chairs of the Hawaii State Senate Committees
n Health and Human Services and Public Housing,
the House of Representatives Committees on Health and
Human Services and Housing, and the state Attorney General; and
BE IT FURTHER RESOLVED that the Department of Health
is requested to review all existing reports, studies, experiments,
and related literature on aspartame, including clinical studies,
differentiating each study by its funding source,
and submit a report to the Legislature no later than twenty days
prior to the convening of the 2008 Regular Session; and
BE IT FURTHER RESOLVED that the
Nation Academy of Sciences is requested to review all existing
reports, studies, experiments, and related literature on aspartame,
including clinical studies, differentiating each study by its funding
source, and that, if funding is required to undertake this extended
evaluation, that the appropriate funding be sought from various
foundations and from Congress; and
BE IT FURTHER RESOLVED that given the enormous amount of
evidence that has been compiled concerning the neurodegenerative
harm it can cause,
that the United States Food and Drug Administration is requested
to rescind approval of aspartame immediately
on a phase-out basis over six months to one year; and
BE IT FURTHER RESOLVED that certified copies of this Resolution
be transmitted to the members of Hawaii's Congressional Delegation,
the Commissioner of the
United States Food and Drug Administration,
the Executive Director of the National Academy of Sciences,
the Director of Health,
the Director of Human Services,
the Attorney General,
and the Director of Commerce and Consumer Affairs.

[ Rich Murray comments: As a medical layman volunteer information
activist for aspartame and related toxicity issues since January 1999,
I note with appreciation the remarkable exponential progress on all
fronts, including a rapidly emerging consensus about the primary
importance of all toxicity challenges for our world.
This lengthy review features in detail two quite different, revolutionary
contributions, from Canada, and England and China.
It is indicative of our times that the CL Nie et al. study, 2007
appears in a free, open access journal -- indeed, as all life and
death information must.
Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a
30-page review as 3 pages a decade ago -- and such reviews
are archived forever in multiple collections, open via global search
engines to a billion Net citizens.
Perforce, and increasingly happily, all societal entities will have to
operate by high and shared voluntary universal standards
for the common good. ]

(2007) Formic Acid, a Novel Metabolite of Chronic Ethanol
Abuse, Causes Neurotoxicity, Which Is Prevented by Folic Acid
Alcoholism: Clinical and Experimental Research 31 (12), 2114-2120.
doi:10.1111/j.1530-0277.2007.00541.x
Abstract
Background:
Methanol is endogenously formed in the brain and is present as a
congener in most alcoholic beverages.
Because ethanol is preferentially metabolized over methanol (MeOH)
by alcohol dehydrogenase, it is not surprising that MeOH
accumulates in the alcohol-abusing population.
This suggests that the alcohol-drinking population will have higher
levels of MeOH's neurotoxic metabolite, formic acid (FA).
FA elimination is mediated by folic acid.
Neurotoxicity is a common result of chronic alcoholism.
This study shows for the first time that FA,
found in chronic alcoholics, is neurotoxic
and this toxicity can be mitigated by folic acid administration.
Objective:
To determine if FA levels are higher in the alcohol-drinking
population and to assess its neurotoxicity in organotypic
hippocampal rat brain slice cultures.
Methods:
Serum and CSF FA was measured in samples from both ethanol
abusing and control patients, who presented to a hospital emergency
department. [ CSF = Cerebral Spinal Fluid ]
FA's neurotoxicity and its reversibility by folic acid were assessed
using organotypic rat brain hippocampal slice cultures using clinically
relevant concentrations.
Results:
Serum FA levels in the alcoholics
(mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls
(mean ± SE: 0.154 +- 0.009 mmol/l, n = 82) (p < 0.0002).
FA was not detected in the controls' CSF (n = 20),
whereas it was >0.15 mmol/l in CSF of 3 of the 4 alcoholic cases.
Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours
to the rat brain slice cultures caused neuronal death as measured by
propidium iodide staining.
When folic acid (1 umol/l) was added with the FA,
neuronal death was prevented. [ umol = micromole ]
Conclusions:
Formic acid may be a significant factor in the neurotoxicity of
ethanol abuse.
This neurotoxicity can be mitigated by folic acid administration
at a clinically relevant dose.
Key Words:
Formic Acid, Folic Acid, Methanol, Neurotoxicity, Alcoholism.

"But the one-third who ate the most fried food increased their risk
by 25 percent, compared with the one-third who ate the least, and
surprisingly, the risk of developing metabolic syndrome was 34
percent higher among those who drank one can of diet soda a day
compared with those who drank none.
"This is interesting," said Lyn M. Steffen, an associate professor of
epidemiology at the University of Minnesota and a co-author of the
paper, which was posted online in the journal Circulation on Jan. 22.
"Why is it happening? Is it some kind of chemical in the diet soda,
or something about the behavior of diet soda drinkers?""
"The diet soda association was not hypothesized
and deserves further study."

...DMDC decomposes primarily to CO2 and methanol ...
[ Note: Sterilization of bacteria and fungi is a toxic process,
probably due to the inevitable conversion in the body of methanol
into highly toxic formaldehyde and then formic acid. ]
The use of 200 mg DMDC per liter would add 98 mg/L of methanol to wine which
already contains an average of about 140 mg/L from natural sources.

A hangover is characterized by the unpleasant physical and mental
symptoms that occur between 8 and 16 hours after drinking alcohol.
After inducing experimental hangover in normal individuals,
we measured the methanol concentration prior to
and after alcohol consumption
and we assessed the association between the hangover condition
and the blood methanol level.
A total of 18 normal adult males participated in this study.
They did not have any previous histories of psychiatric
or medical disorders.
The blood ethanol concentration prior to the alcohol intake
(2.26+/-2.08) was not significantly different from that
13 hours after the alcohol consumption (3.12+/-2.38).
However, the difference of methanol concentration
between the day of experiment (prior to the alcohol intake)
and the next day (13 hours after the alcohol intake)
was significant (2.62+/-1.33/l vs. 3.88+/-2.10/l, respectively).
A significant positive correlation was observed
between the changes of blood methanol concentration
and hangover subjective scale score increment when covarying
for the changes of blood ethanol level (r=0.498, p<0.05).
This result suggests the possible correlation of methanol
as well as its toxic metabolite to hangover. PMID: 16318957
[ The toxic metabolite of methanol is formaldehyde, which in turn
partially becomes formic acid -- both potent cumulative toxins
that are the actual cause of the toxicity of methanol.]
This study by Jones AW (1987) found next-morning hangover

Fully 11% of aspartame is methanol --
1,120 mg aspartame in 2 L diet soda,
almost six 12-oz cans, gives 123 mg methanol (wood alcohol).

This paper reports the elimination half-life of methanol in human

Experiments were made during the morning after the subjects had
consumed 1000-1500 ml red wine
(9.5 % w/v ethanol, 100 mg/l methanol)
the previous evening. [ 100 to 150 mg methanol ]
The washout of methanol from the body
coincided with the onset of hangover.
The concentrations of ethanol and methanol in blood were
determined indirectly by analysis of end-expired alveolar air.
In the morning when blood-ethanol dropped
below the Km of liver alcohol dehydrogenase (ADH)
of about 100 mg/l (2.2 mM),
the disappearance half-life of ethanol was 21, 22, 18 and 15 min.
in 4 test subjects respectively.
The corresponding elimination half-lives of methanol
were 213, 110, 133 and 142 min. in these same individuals.
The experimental design outlined in this paper can be used
to obtain useful data on elimination kinetics of methanol
in human volunteers without undue ethical limitations.
Circumstantial evidence is presented to link methanol
or its toxic metabolic products, formaldehyde and formic acid,
with the pathogenesis of hangover. PMID: 3588516

formaldehyde in FEMA trailers and other sources (aspartame,
dark wines and liquors, tobacco smoke): Murray 2008.01.30
http://rmforall.blogspot.com/2008_01_01_archive.htm
Wednesday, January 30, 2008
http://groups.yahoo.com/group/aspartameNM/message/1508
The FEMA trailers give about the same amount of formaldehyde
daily as from a quart of dark wine or liquor, or two quarts
(6 12-oz cans) of aspartame diet soda, from their over 1 tenth gram
methanol impurity (one part in 10,000),
which the body quickly makes into formaldehyde -- enough
to be the major cause of "morning after" alcohol hangovers.
Methanol and formaldehyde also result from many fruits and
vegetables, tobacco and wood smoke, heater and vehicle exhaust,
household chemicals and cleaners, cosmetics, and new cars, drapes,
carpets, furniture, particleboard, mobile homes, buildings, leather ...
so all these sources add up and interact
with many other toxic chemicals.
BN Ames and LS Gold, 1998, have presented detailed information
that there is no increase in recent decades for most cancers,
and that common carcinogens do not result in significant exposures
to the average human population.
However, individuals are not average -- each person has a unique genetic
makeup, resulting in a huge range of variation of vulnerability to
specific chemicals, as is well evidenced in the case of methanol,
formaldehyde, and formic acid, especially with regard
to behavioral effects.
Each is subject to very wide ranges of exposure levels.
Many are in especially vulnerable groups, depending on diet, obesity,
sex, exercise, life stress, age from conception to very old, unusually
severe toxic exposures, injuries, and diseases.
It is clear that a variety of multiple chemical sensitivity syndromes do
exist, often with remarkable hypersensitivity.
Methanol, formaldehyde, and formic acid toxicity are unusual, in that
humans are far more vulnerable than any other mammal, as much as ten
to sixty-fold, which complicates the utility of animal data.
The unusally long human life span also increases the role of long-term
chronic low-level exposure.

Abstract:
Adult male rats were given an oral dose of 10 mg/kg aspartame,
14C-labeled in the methanol carbon.
At timed intervals of up to 6 hours, the radioactivity in plasma
and several organs was investigated.
Most of the radioactivity found (>98 % in plasma, >75 % in liver)
was bound to protein.
Label present in liver, plasma and kidney was in the range
of 1-2 % of total radioactivity administered per g or mL,
changing little with time.
Other organs (brown and white adipose tissues, muscle, brain,
cornea and retina) contained levels of label
in the range of 1/12th to 1/10th of that of liver.
In all, the rats retained, 6 hours after administration,
about 5 % of the label, half of it in the liver.
The specific radioactivity of tissue protein, RNA and DNA
was quite uniform.
The protein label was concentrated in amino acids,
different from methionine, and largely coincident
with the result of protein exposure to labeled formaldehyde.
DNA radioactivity was essentially in a single different adduct base,
different from the normal bases present in DNA.
The nature of the tissue label accumulated was, thus,
a direct consequence of formaldehyde binding to tissue structures.
The administration of labeled aspartame to a group of cirrhotic rats
resulted in comparable label retention by tissue components,
which suggests that liver function (or its defect) has little effect
on formaldehyde formation from aspartame
and binding to biological components.
The chronic treatment of a series of rats with 200 mg/kg of
non-labeled aspartame during 10 days results in the accumulation
of even more label when given the radioactive bolus,
suggesting that the amount of formaldehyde adducts
coming from aspartame in tissue proteins and nucleic acids
may be cumulative.
It is concluded that aspartame consumption may constitute
a hazard because of its contribution
to the formation of formaldehyde adducts. PMID: 9714421
[ Extracts ]
"The high label presence in plasma and liver is in agreement with the
carriage of the label from the intestine to the liver via the portal vein.
The high label levels in kidney and, to a minor extent, in brown
adipose tissue and brain are probably a consequence
of their high blood flows (45).
Even in white adipose tissue, the levels of radioactivity found 6 hours
after oral administration were 1/25th those of liver.
Cornea and retina, both tissues known to metabolize actively
methanol (21,28) showed low levels of retained label.
In any case, the binding of methanol-derived carbon to tissue proteins
was widespread, affecting all systems,
fully reaching even sensitive targets such as the brain and retina....
The amount of label recovered in tissue components was quite high
in all the groups, but especially in the NA rats.
In them, the liver alone retained, for a long time, more than 2 % of the
methanol carbon given in a single oral dose of aspartame,
and the rest of the body stored an additional 2 % or more.
These are indeed extremely high levels for adducts of formaldehyde, a
substance responsible of chronic deleterious effects (33), that has also
been considered carcinogenic (34,47).
The repeated occurrence of claims that aspartame
produces headache and other neurological and psychological
secondary effects --
more often than not challenged by careful analysis --
(5, 9, 10, 15, 48)
may eventually find at least a partial explanation in the permanence
of the formaldehyde label,
since formaldehyde intoxication can induce similar effects (49).
The cumulative effects derived from the incorporation of label in the
chronic administration model suggests that regular intake of aspartame
may result in the progressive accumulation of formaldehyde adducts.
It may be further speculated that the formation of adducts can help to
explain the chronic effects aspartame consumption may induce on
sensitive tissues such as brain (6, 9, 19, 50).
In any case, the possible negative effects that the accumulation of
formaldehyde adducts can induce is, obviously, long-term.
The alteration of protein integrity and function may needs some time
to induce substantial effects.
The damage to nucleic acids, mainly to DNA,
may eventually induce cell death and/or mutations.
The results presented suggest that the conversion of aspartame
methanol into formaldehyde adducts in significant amounts in vivo
should to be taken into account because of the widespread utilization
of this sweetener.
Further epidemiological and long-term studies are needed to
determine the extent of the hazard that aspartame consumption
poses for humans."

Dr. Woodrow C. Monte Aspartame: methanol, and the public health.

The methanol from 2 L of diet soda, 5.6 12-oz cans, 20 mg/can, is
112 mg, 10% of the aspartame.
The EPA limit for water is 7.8 mg daily for methanol (wood alcohol),
a deadly cumulative poison.
Many users drink 1-2 L daily.
The reported symptoms are entirely consistent with chronic methanol
toxicity. (Fresh orange juice has 34 mg/L, but, like all juices, has 16
times more ethanol, which strongly protects against methanol.)
"The greater toxicity of methanol to man is deeply rooted in the
limited biochemical pathways available to humans for detoxification.
The loss of uricase (EC 1.7.3.3.),
formyl-tetrahydrofolate synthetase (EC 6.3.4.3.) (42)
and other enzymes (18) during evolution sets man apart from all
laboratory animals including the monkey (42).
There is no generally accepted animal model
for methanol toxicity (42, 59).
Humans suffer "toxic syndrome" (54) at a minimum lethal dose
of <1 gm/kg, much less than that of monkeys, 3-6 g/kg (42, 59).
The minimum lethal dose of methanol
in the rat, rabbit, and dog is 9.5, 7.0 , and 8.0 g/kg, respectively (43);
ethyl alcohol is more toxic than methanol to these test animals (43)."
Recent research [see links at end of post] supports his focus on the
methanol to formaldehyde toxic process:
"The United States Environmental Protection Agency in their
Multimedia Environmental Goals for Environmental Assessment
recommends a minimum acute toxicity concentration
of methanol in drinking water at 3.9 parts per million,
with a recommended limit of consumption below 7.8 mg/day (8).
This report clearly indicates that methanol:
"...is considered a cumulative poison due to the low rate of excretion
once it is absorbed. In the body, methanol is oxidized to formaldehyde
and formic acid; both of these metabolites are toxic." (8)...
Recently the toxic role of formaldehyde (in methanol toxicity) has been
questioned (34).
No skeptic can overlook the fact that, metabolically, formaldehyde
must be formed as an intermediate to formic acid production (54).
Formaldehyde has a high reactivity which may be why it has not been
found in humans or other primates during methanol poisoning (59)....
If formaldehyde is produced from methanol and does have a
reasonable half life within certain cells in the poisoned organism
he chronic toxicological ramifications could be grave.
Formaldehyde is a known carcinogen (57) producing squanous-cell
carcinomas by inhalation exposure in experimental animals (22).
The available epidemiological studies do not provide adequate data
for assessing the carcinogenicity of formaldehyde in man (22, 24, 57).
However, reaction of formaldehyde with deoxyribonucleic acid
(DNA) has resulted in irreversible denaturation that could interfere
with DNA replication and result in mutation (37)..."
It is certain that high levels of aspartame use,
above 2 liters daily for months and years,
must lead to chronic formaldehyde-formic acid toxicity.
Fully 11 % of aspartame is methanol -- 1,120 mg aspartame
in 2 L diet soda, almost six 12-oz cans, gives 123 mg methanol
(wood alcohol). The methanol is immediately released
into the body after drinking .
Within hours, the liver turns much of the methanol into formaldehyde,
and then much of that into formic acid, both of which in time
are partially eliminated as carbon dioxide and water.
However, about 30 % of the methanol remains in the body
as cumulative durable toxic metabolites of formaldehyde
and formic acid -- 37 mg daily,
a gram every month, accumulating in and affecting every tissue.
If only 10 % of the methanol is retained daily as formaldehyde,
that would give 12 mg daily formaldehyde accumulation -- about
60 times more than the 0.2 mg from 10 % retention
of the 2 mg EPA daily limit for formaldehyde in drinking water.
Bear in mind that the EPA limit for formaldehyde in drinking water is
1 ppm, or 2 mg daily for a typical daily consumption of 2 L of water.

This long-term low-level chronic toxic exposure leads to typical
patterns of increasingly severe complex symptoms,
starting with headache, fatigue, joint pain, irritability, memory loss,
rashes, and leading to vision and eye problems, and even seizures.
In many cases there is addiction. Probably there are immune system
disorders, with a hypersensitivity to these toxins and other chemicals.

They found that about 70 % of the radioactive methanol in aspartame
put into the stomachs of 3 to 7 kg monkeys
was eliminated within 8 hours, with little additional elimination,
as carbon dioxide in exhaled air and as water in the urine.
They did not mention that this meant that about 30 % of the methanol
must transform into formaldehyde and then into formic acid,
both of which must remain as toxic products in all parts of the body.
They did not report any studies on the distribution of radioactivity
in body tissues, except that blood plasma proteins after 4 days
held 4 % of the initial methanol.
This study did not monitor long-term use of aspartame.
The low oral dose of aspartame and for methanol
was 0.068 mmol/kg, about 1 part per million [ppm]
of the acute toxicity level of 2,000 mg/kg, 67,000
mmol/kg, used by McMartin (1979).
Two L daily use of diet soda provides 123 mg methanol,
2 mg/kg for a 60 kg person, a dose of 67 mmole/kg,
a thousand times more than the dose in this study.
By eight hours excretion of the dose in air and urine had leveled off at
67.1 +-2.1 % as CO2 in the exhaled air
and 1.57+-0.32 % in the urine, so 68.7 % was excreted,
and 31.3 % was retained.
This data is the average of 4 monkeys.
"...the 14C in the feces was negligible."
"That fraction not so excreted (about 31%) was converted to body
constituents through the one-carbon metabolic pool."
"All radioactivity measurements were counted to +-1 % accuracy..."
This indicates that the results could not be claimed to have a precision of
a tenth of a percent. OK, so this is a nit-pick -- but I believe espousing
spurious accuracy is a sign of scientific insecurity.
The abstract ends, "It was concluded that aspartame was digested to
its three constituents that were then absorbed
as natural constituents of the diet.
Thus, the concept is very subtly insinuated that methanol, as a
constituent of aspartame, is absorbed as a natural constituent
of the diet.
Nowhere in this report are mentioned the dread words,
"formaldehyde" and "formic acid".
Of course, methanol and formaldehyde toxicity studies are highly
relevant to the issue of aspartame toxicity.
[ Aspartame has to be turned into its toxic products,
formaldehyde and formic acid, in the body, before it is toxic,
so some pro-aspartame reseach studies test aspartame outside the
body, and then proclaim that they have proved that it is not toxic. ]

Hawaii Senate Committee Will Consider Resolution on Aspartame
By Stephen Fox, 3/13/2008 10:49:31 AM
There is now a Hawaii Senate Resolution,
authored by Sen. Suzanne Chun Oakland, which requests the
Department of Health and National Academy of Sciences
to review existing reports and studies related to aspartame,
by funding source.
It resolves that given the enormous amount of evidence
that has been compiled concerning the neurodegenerative harm
it can cause, that the U.S. Food and Drug Administration
is requested to rescind approval of aspartame immediately
on a phase-out basis over six months to one year.
We are very pleased to note that this is the strongest legislative
document concerning aspartame ever presented anywhere
in the world.
On March 12, another resolution, HCR132, introduced by Rep.
Josh Green, M.D., Chairman of the House Committee on Health,
was approved by its first committee (Health),
and moves on to the next (Consumer Protection and Commerce).
This would set up a work group to explore the need to ban
or improve labeling containing aspartame.
It was again opposed by Dr. Chiyome Fukino, M.D.,
Director of the Health Department,
an appointee of Republican Governor Linda Lingle,
who opposed the House Bill to ban aspartame on the flawed basis
of an Ajinomoto-funded review study;
Ajinomoto is the world's largest manufacturer of Aspartame,
and another proven neurotoxic food additive,
Monosodium Glutamate.
Betty Martini, D. Hum, sent Dr. Fukino a detailed rebuttal
to this study, showing the links to Ajinomoto
and flawed industry research.
Dr. Fukino's opposition today, March 12 was surprisingly opposed
by Rep. Green, M.D., the only physician in the entire Hawaii
Legislature, in view of him having 'deferred' a prior bill to ban
aspartame outright, by statute.
Here is the rebuttal to the Ajinomoto Study, written by Mark Gold,
Founder, Aspartame Toxicity Information Center, New Hampshire:
http://www.holisticmed.com/aspartame/burdock/
Aspartame and Manufacturer-Funded Scientific Reviews
This flawed Ajinomoto-funded report,
which has been touted far and wide by aspartame manufacturers
and corporate hacks and lobbyists, shows how far the world's
largest aspartame manufacturer will go to deceive the public.
However, today, there is no doubt that Ajinomoto's
Board of Directors as well as the Board of Directors of
Coca Cola, Pepsi, Wrigley's Gum, and Merisant
(manufacturer of Equal) are extremely worried about these
late-breaking developments in Hawaii, which should also
encourage consumer protection activists all over the world
to contact their legislators and parliamentarians, asking them
to introduce similar legislation and Resolutions.
We cordially thank Senator Chun Oakland and Representative
Josh Green, M.D., for advancing our consumer protection initiative
as far as they have.
Text of Senate Resolution:
http://www.capitol.hawaii.gov/session2008/bills/SCR191_.pdf
Requesting the Hawaii Department of Health and
the National Academy of Sciences to review existing reports
and studies related to Aspartame, and Requesting the United States
Food and Drug Administration to Rescind Approval for
United States Markets,
carried by Hawaii Senator Suzanne Chun Oakland
Whereas, aspartame was originally developed as a drug to treat
peptic ulcers; and
Whereas, manufacturers state that aspartame is made up of
forty per cent aspartic acid, fifty percent phenylalanine,
and ten per cent methanol; and
Whereas, aspartic acid is a nonessential amino acid
that is used by the body to initiate apoptosis or cell death
in aging cells,
and that excess aspartic acid from aspartame consumption causes
apoptosis in health cells that can destroy healthy tissue,
especially in the brain; and
Whereas, phenylalanine is an essential amino acid found naturally
in protein but when isolated becomes neurotoxic, lowers the seizure
threshold, depletes serotonin -- triggering psychiatric and behavioral
problems -- and interacts with depressants and other drugs; and
Whereas, methanol is a severe metabolic poison classified as a
narcotic that converts to formaldehyde and formic acid,
and can embalm living tissue and damage DNA; and
Whereas, aspartame metabolites include formaldehyde,
a 'class A' carcinogen, and diketopiperazine, a brain tumor agent,
and formic acid, and
Whereas, in 1974, the United States Food and Drug Administration
approved aspartame as an artificial sweetener,
but asked its manufacturer Searle to hold back from selling it on the
market until further tests could be made with regards to its safety;
and
Whereas, scientific data revealed that there was a problem with
aspartame safety date and the United States Food and Drug
Administration withdrew its approval; and
Whereas, in 1975, the United States Food and Drug
Administration initiated an investigation into Searle's laboratory
practices and discovered fraud in scientific experiments as well as
manipulated data giving favorable results proving aspartame
to be safe; and
Whereas, the results of this investigation are included in
what is called 'The Bressler Report' by Jerome Bressler; and

Whereas, in 1980, Dr. John Olney submitted scientific data to a
United States Food and Drug Administration Public Board of Inquiry
showing that aspartic acid, the excitotoxic ingredient in aspartame,
caused holes in the brains of mice; and
Whereas, Dr. John Olney stated that it warranted special emphasis
that excitotoxins act by an acute but silent mechanism, requiring
only a single exposure for CVO neurons to be quietly destroyed,
that clearly Searle failed to establish the safety of their product,
aspartame, for use in children's food, and that all age comparative
data support the following conclusions:
(1) orally administered excitotoxins destroy CVO neurons
at any age;
(2) immature animals are most vulnerable; and
(3) the toxic threshold increases only gradually between birth and
adulthood; and
Whereas, in 1980, the Public Board of Inquiry unanimously
voted against aspartame approval, but was overruled by a new
United States Food and Drug Administration Commissioner,
Dr. Arthur Hull Hayes, against the advice of Food and Drug
Administration scientific personnel and advisers; and
Whereas, the United States Food and Drug Administration
approved aspartame use in sodas, despite the fact that the
National Soft Drink Association argued vehemently against
aspartame in these quotes from their protest:
[ With their original name, The National Soft Drink Association, they
condemned aspartame on July 28, 1983 in a detailed critique:
http://dorway.com/dorwblog/?page_id=60 ]
* (1) "The present record does not contain data which
demonstrate that the use of APM in soft drinks will not result in the
adulteration of the beverages under Section 402(a)(3) of the
FDC Act 21 U.S.S. 342 (a)(3),
which provides that a food is adulterated if it contains, in whole
or in part, 'a decomposed substance
or it is otherwise unfit for food'�)";
(2) "An important decomposition product of aspartame,
aspartic acid, cannot be detected at all using TLC"�;
(3) "�G.D. Searle and Company has not demonstrated to a reasonable
certainty that the use of aspartame in soft drinks, without quantitative limitations, will not adversely affect human health as a result of the changes such use is likely to cause in brain chemistry and under certain reasonably anticipated conditions of use"; and
(4) "Specifically, Searle has not met its burdens under section
409 'to demonstrate that aspartame is safe and functional for use
in soft drinks.' Collectively, the extensive deficiencies in the stability studies conducted by Searle to demonstrate that aspartame and its degradation products are safe in soft drinks intended to be sold in the United States, render those studies inadequate and unreliable."�
Senate Congressional Record, May 7, 1985, S5507-5511: and
Whereas, the United States Food and Drug Administration
has compiled a list of ninety-two symptoms attributed to aspartame
consumption including four types of seizures, coma, and death; and
Whereas, the Ramazzini Studies by the European Foundation for Oncology in Italy conducted exhaustive studies over three years with thousands of rats, and proved aspartame to be a multipotential carcinogen, thus confirming the United States Food and Drug Administration's original findings;
and
Whereas, the United States Food and Drug Administration
admitted that aspartame caused cancer over two decades ago,
when the Administration's toxicologist, Dr. Adrian Gross, told
Congress at least one of Searle's studies:
"has established beyond any reasonable doubt that aspartame is
capable of inducing brain tumors in experimental animals and that
this predisposition of it is of extremely high significance". In view
of these indications that the cancer causing potential of aspartame
is a matter that had been established way beyond any reasonable
doubt, one can ask: What is the reason for the apparent refusal
by the FDA to invoke for this food additive the so-called Delaney
amendment to the Food, Drug, and Cosmetic act?
Given the cancer causing potential of aspartame, how would the
FDA justify its position that it views a certain amount of aspartame
as constituting an allowable daily intake or 'safe' level of it?
Is that position in effect not equivalent to setting a 'tolerance'
for this food additive and thus a violation of that law?
And if the FDA itself elects to violate the law,
who is left to protect the health of the public?"�
Congressional Record, August 1, 1985, SID835: 131: and
Whereas, aspartame is linked to sudden death, multiple sclerosis,
lupus, and many neurodegenerative diseases, as cited in may medical
texts, most notably: Aspartame Disease: An Ignored Epidemic,
by H.J. Roberts, M.D., and
Excitotoxins: the Taste that Kills, By Russell Blaylock, M.D., and
Whereas, on November 3, 1987, Dr. Louis Elsas told Congress:
"I am a pediatrician, a Professor of Pediatrics at Emory
and have spent twenty-five years in the biomedical sciences,
trying to prevent mental retardation and birth defect caused by excess
phenylalanine, and therein lies my basic concern, that aspartame is
in fact a well known neurotoxin and teratogen which, in some as yet
undefined dose, will irreversibly in the developing child or fetal brain, produce adverse effects." and
Whereas, there are tens of thousands of case histories and anecdotal
accounts from victims of aspartame poisoning who have come forward to make their case histories known; now, therefore,
BE IT RESOLVED by the Senate of the Twenty-Fourth Legislature
of the State of Hawaii, Regular Session of 2008,
the House of Representatives concurring,
that the Department of Health is requested to create,
within their existing budget,
an evidentiary repository accessible to the public for patients and
physicians to submit of the next year their cases involving victims
of aspartame poisoning; and
BE IT FURTHER RESOLVED that the Director of Health
is requested to report to the Legislature on the status of the
evidentiary repository during periodic interim meetings
with the Chairs of the Hawaii State Senate Committees
n Health and Human Services and Public Housing,
the House of Representatives Committees on Health and
Human Services and Housing, and the state Attorney General; and
BE IT FURTHER RESOLVED that the Department of Health
is requested to review all existing reports, studies, experiments,
and related literature on aspartame, including clinical studies,
differentiating each study by its funding source,
and submit a report to the Legislature no later than twenty days
prior to the convening of the 2008 Regular Session; and
BE IT FURTHER RESOLVED that the
Nation Academy of Sciences is requested to review all existing
reports, studies, experiments, and related literature on aspartame,
including clinical studies, differentiating each study by its funding
source, and that, if funding is required to undertake this extended
evaluation, that the appropriate funding be sought from various
foundations and from Congress; and
BE IT FURTHER RESOLVED that given the enormous amount of
evidence that has been compiled concerning the neurodegenerative
harm it can cause,
that the United States Food and Drug Administration is requested
to rescind approval of aspartame immediately
on a phase-out basis over six months to one year; and
BE IT FURTHER RESOLVED that certified copies of this Resolution
be transmitted to the members of Hawaii's Congressional Delegation,
the Commissioner of the
United States Food and Drug Administration,
the Executive Director of the National Academy of Sciences,

[ Rich Murray comments: As a medical layman volunteer information
activist for aspartame and related toxicity issues since January 1999,
I note with appreciation the remarkable exponential progress on all
fronts, including a rapidly emerging consensus about the primary
importance of all toxicity challenges for our world.
This lengthy review features in detail two quite different, revolutionary
contributions, from Canada, and England and China.
It is indicative of our times that the CL Nie et al. study, 2007
appears in a free, open access journal -- indeed, as all life and
death information must.
Following rather vigorously, indeed blindly, the imperatives of
single-minded, profit-driven capitalist competition -- manipulating
adroitly research, education, media, citizens, governments -- many
great global corporations have inevitably created results that
oppose the common good. Alcohol and tobacco are well known.
Realistically, any further manipulations can only lead to inevitable
and even sudden corporate meltdowns, in the context of an
unfettered, cooperative, democratic global information forum,
the Internet.
Now, it is as easy and cheap to compose and instantly post a

are archived forever in multiple collections, open via global search

(2007) Formic Acid, a Novel Metabolite of Chronic Ethanol
Abuse, Causes Neurotoxicity, Which Is Prevented by Folic Acid
Alcoholism: Clinical and Experimental Research 31 (12), 2114-2120.
doi:10.1111/j.1530-0277.2007.00541.x
Abstract
Background:
Methanol is endogenously formed in the brain and is present as a
congener in most alcoholic beverages.
Because ethanol is preferentially metabolized over methanol (MeOH)
by alcohol dehydrogenase, it is not surprising that MeOH
accumulates in the alcohol-abusing population.
This suggests that the alcohol-drinking population will have higher
levels of MeOH's neurotoxic metabolite, formic acid (FA).
FA elimination is mediated by folic acid.
Neurotoxicity is a common result of chronic alcoholism.
This study shows for the first time that FA,
found in chronic alcoholics, is neurotoxic
and this toxicity can be mitigated by folic acid administration.
Objective:
To determine if FA levels are higher in the alcohol-drinking
population and to assess its neurotoxicity in organotypic
hippocampal rat brain slice cultures.
Methods:
Serum and CSF FA was measured in samples from both ethanol
abusing and control patients, who presented to a hospital emergency
department. [ CSF = Cerebral Spinal Fluid ]
FA's neurotoxicity and its reversibility by folic acid were assessed
using organotypic rat brain hippocampal slice cultures using clinically
relevant concentrations.
Results:
Serum FA levels in the alcoholics
(mean ± SE: 0.416 +- 0.093 mmol/l, n = 23)
were significantly higher than in controls
(mean ± SE: 0.154 +- 0.009 mmol/l, n = 82) (p < 0.0002).
FA was not detected in the controls' CSF (n = 20),
whereas it was >0.15 mmol/l in CSF of 3 of the 4 alcoholic cases.
Low doses of FA from 1 to 5 mmol/l added for 24, 48 or 72 hours
to the rat brain slice cultures caused neuronal death as measured by
propidium iodide staining.
When folic acid (1 umol/l) was added with the FA,
neuronal death was prevented. [ umol = micromole ]
Conclusions:
Formic acid may be a significant factor in the neurotoxicity of
ethanol abuse.
This neurotoxicity can be mitigated by folic acid administration
at a clinically relevant dose.
Key Words:
Formic Acid, Folic Acid, Methanol, Neurotoxicity, Alcoholism.

...DMDC decomposes primarily to CO2 and methanol ...
[ Note: Sterilization of bacteria and fungi is a toxic process,
probably due to the inevitable conversion in the body of methanol
into highly toxic formaldehyde and then formic acid. ]
The use of 200 mg DMDC per liter would add 98 mg/L of methanol to wine which
already contains an average of about 140 mg/L from natural sources.

A hangover is characterized by the unpleasant physical and mental
symptoms that occur between 8 and 16 hours after drinking alcohol.
After inducing experimental hangover in normal individuals,
we measured the methanol concentration prior to
and after alcohol consumption
and we assessed the association between the hangover condition
and the blood methanol level.
A total of 18 normal adult males participated in this study.
They did not have any previous histories of psychiatric
or medical disorders.
The blood ethanol concentration prior to the alcohol intake
(2.26+/-2.08) was not significantly different from that
13 hours after the alcohol consumption (3.12+/-2.38).
However, the difference of methanol concentration
between the day of experiment (prior to the alcohol intake)
and the next day (13 hours after the alcohol intake)
was significant (2.62+/-1.33/l vs. 3.88+/-2.10/l, respectively).
A significant positive correlation was observed
between the changes of blood methanol concentration
and hangover subjective scale score increment when covarying
for the changes of blood ethanol level (r=0.498, p<0.05).
This result suggests the possible correlation of methanol
as well as its toxic metabolite to hangover. PMID: 16318957
[ The toxic metabolite of methanol is formaldehyde, which in turn
partially becomes formic acid -- both potent cumulative toxins
that are the actual cause of the toxicity of methanol.]
This study by Jones AW (1987) found next-morning hangover
from red wine with 100 to 150 mg methanol
(9.5 % w/v ethanol, 100 mg/l methanol, 0.01 %).
Fully 11% of aspartame is methanol --
1,120 mg aspartame in 2 L diet soda,
almost six 12-oz cans, gives 123 mg methanol (wood alcohol).

Elimination half-life of methanol during hangover.
Jones AW. wayne.jones@RMV.se
Department of Forensic Toxicology,
University Hospital, SE-581 85 Linkoping, Sweden.
This paper reports the elimination half-life of methanol in human
volunteers.
Experiments were made during the morning after the subjects had
consumed 1000-1500 ml red wine
(9.5 % w/v ethanol, 100 mg/l methanol)
the previous evening. [ 100 to 150 mg methanol ]
The washout of methanol from the body
coincided with the onset of hangover.
The concentrations of ethanol and methanol in blood were
determined indirectly by analysis of end-expired alveolar air.
In the morning when blood-ethanol dropped
below the Km of liver alcohol dehydrogenase (ADH)
of about 100 mg/l (2.2 mM),
the disappearance half-life of ethanol was 21, 22, 18 and 15 min.
in 4 test subjects respectively.
The corresponding elimination half-lives of methanol
were 213, 110, 133 and 142 min. in these same individuals.
The experimental design outlined in this paper can be used
to obtain useful data on elimination kinetics of methanol
in human volunteers without undue ethical limitations.
Circumstantial evidence is presented to link methanol
or its toxic metabolic products, formaldehyde and formic acid,
with the pathogenesis of hangover. PMID: 3588516

formaldehyde in FEMA trailers and other sources (aspartame,
dark wines and liquors, tobacco smoke): Murray 2008.01.30
http://rmforall.blogspot.com/2008_01_01_archive.htm
Wednesday, January 30, 2008
http://groups.yahoo.com/group/aspartameNM/message/1508
The FEMA trailers give about the same amount of formaldehyde
daily as from a quart of dark wine or liquor, or two quarts
(6 12-oz cans) of aspartame diet soda, from their over 1 tenth gram
methanol impurity (one part in 10,000),
which the body quickly makes into formaldehyde -- enough
to be the major cause of "morning after" alcohol hangovers.
Methanol and formaldehyde also result from many fruits and
vegetables, tobacco and wood smoke, heater and vehicle exhaust,
household chemicals and cleaners, cosmetics, and new cars, drapes,
carpets, furniture, particleboard, mobile homes, buildings, leather ...
so all these sources add up and interact
with many other toxic chemicals.
BN Ames and LS Gold, 1998, have presented detailed information
that there is no increase in recent decades for most cancers,
and that common carcinogens do not result in significant exposures
to the average human population.
However, individuals are not average -- each person has a unique genetic
makeup, resulting in a huge range of variation of vulnerability to
specific chemicals, as is well evidenced in the case of methanol,
formaldehyde, and formic acid, especially with regard
to behavioral effects.
Each is subject to very wide ranges of exposure levels.
Many are in especially vulnerable groups, depending on diet, obesity,
sex, exercise, life stress, age from conception to very old, unusually
severe toxic exposures, injuries, and diseases.
It is clear that a variety of multiple chemical sensitivity syndromes do
exist, often with remarkable hypersensitivity.
Methanol, formaldehyde, and formic acid toxicity are unusual, in that
humans are far more vulnerable than any other mammal, as much as ten
to sixty-fold, which complicates the utility of animal data.
The unusally long human life span also increases the role of long-term
chronic low-level exposure.

which have a much greater tolerance for aspartame than humans.
So, the corresponding level for humans would be about 1 or 2 mg/kg.

Abstract:
Adult male rats were given an oral dose of 10 mg/kg aspartame,
14C-labeled in the methanol carbon.
At timed intervals of up to 6 hours, the radioactivity in plasma
and several organs was investigated.
Most of the radioactivity found (>98 % in plasma, >75 % in liver)
was bound to protein.
Label present in liver, plasma and kidney was in the range
of 1-2 % of total radioactivity administered per g or mL,
changing little with time.
Other organs (brown and white adipose tissues, muscle, brain,
cornea and retina) contained levels of label
in the range of 1/12th to 1/10th of that of liver.
In all, the rats retained, 6 hours after administration,
about 5 % of the label, half of it in the liver.
The specific radioactivity of tissue protein, RNA and DNA
was quite uniform.
The protein label was concentrated in amino acids,
different from methionine, and largely coincident
with the result of protein exposure to labeled formaldehyde.
DNA radioactivity was essentially in a single different adduct base,
different from the normal bases present in DNA.
The nature of the tissue label accumulated was, thus,
a direct consequence of formaldehyde binding to tissue structures.
The administration of labeled aspartame to a group of cirrhotic rats
resulted in comparable label retention by tissue components,
which suggests that liver function (or its defect) has little effect
on formaldehyde formation from aspartame
and binding to biological components.
The chronic treatment of a series of rats with 200 mg/kg of
non-labeled aspartame during 10 days results in the accumulation
of even more label when given the radioactive bolus,
suggesting that the amount of formaldehyde adducts
coming from aspartame in tissue proteins and nucleic acids
may be cumulative.
It is concluded that aspartame consumption may constitute
a hazard because of its contribution
to the formation of formaldehyde adducts. PMID: 9714421
[ Extracts ]
"The high label presence in plasma and liver is in agreement with the
carriage of the label from the intestine to the liver via the portal vein.
The high label levels in kidney and, to a minor extent, in brown
adipose tissue and brain are probably a consequence
of their high blood flows (45).
Even in white adipose tissue, the levels of radioactivity found 6 hours
after oral administration were 1/25th those of liver.
Cornea and retina, both tissues known to metabolize actively
methanol (21,28) showed low levels of retained label.
In any case, the binding of methanol-derived carbon to tissue proteins
was widespread, affecting all systems,
fully reaching even sensitive targets such as the brain and retina....
The amount of label recovered in tissue components was quite high
in all the groups, but especially in the NA rats.
In them, the liver alone retained, for a long time, more than 2 % of the
methanol carbon given in a single oral dose of aspartame,
and the rest of the body stored an additional 2 % or more.
These are indeed extremely high levels for adducts of formaldehyde, a
substance responsible of chronic deleterious effects (33), that has also
been considered carcinogenic (34,47).
The repeated occurrence of claims that aspartame
produces headache and other neurological and psychological
secondary effects --
more often than not challenged by careful analysis --
(5, 9, 10, 15, 48)
may eventually find at least a partial explanation in the permanence
of the formaldehyde label,
since formaldehyde intoxication can induce similar effects (49).
The cumulative effects derived from the incorporation of label in the
chronic administration model suggests that regular intake of aspartame
may result in the progressive accumulation of formaldehyde adducts.
It may be further speculated that the formation of adducts can help to
explain the chronic effects aspartame consumption may induce on
sensitive tissues such as brain (6, 9, 19, 50).
In any case, the possible negative effects that the accumulation of
formaldehyde adducts can induce is, obviously, long-term.
The alteration of protein integrity and function may needs some time
to induce substantial effects.
The damage to nucleic acids, mainly to DNA,
may eventually induce cell death and/or mutations.
The results presented suggest that the conversion of aspartame
methanol into formaldehyde adducts in significant amounts in vivo
should to be taken into account because of the widespread utilization
of this sweetener.
Further epidemiological and long-term studies are needed to
determine the extent of the hazard that aspartame consumption
poses for humans."

The methanol from 2 L of diet soda, 5.6 12-oz cans, 20 mg/can, is
112 mg, 10% of the aspartame.
The EPA limit for water is 7.8 mg daily for methanol (wood alcohol),
a deadly cumulative poison.
Many users drink 1-2 L daily.
The reported symptoms are entirely consistent with chronic methanol
toxicity. (Fresh orange juice has 34 mg/L, but, like all juices, has 16
times more ethanol, which strongly protects against methanol.)
"The greater toxicity of methanol to man is deeply rooted in the
limited biochemical pathways available to humans for detoxification.
The loss of uricase (EC 1.7.3.3.),
formyl-tetrahydrofolate synthetase (EC 6.3.4.3.) (42)
and other enzymes (18) during evolution sets man apart from all
laboratory animals including the monkey (42).
There is no generally accepted animal model
for methanol toxicity (42, 59).
Humans suffer "toxic syndrome" (54) at a minimum lethal dose
of <1 gm/kg, much less than that of monkeys, 3-6 g/kg (42, 59).
The minimum lethal dose of methanol
in the rat, rabbit, and dog is 9.5, 7.0 , and 8.0 g/kg, respectively (43);
ethyl alcohol is more toxic than methanol to these test animals (43)."
Recent research [see links at end of post] supports his focus on the
methanol to formaldehyde toxic process:
"The United States Environmental Protection Agency in their
Multimedia Environmental Goals for Environmental Assessment
recommends a minimum acute toxicity concentration
of methanol in drinking water at 3.9 parts per million,
with a recommended limit of consumption below 7.8 mg/day (8).
This report clearly indicates that methanol:
"...is considered a cumulative poison due to the low rate of excretion
once it is absorbed. In the body, methanol is oxidized to formaldehyde
and formic acid; both of these metabolites are toxic." (8)...
Recently the toxic role of formaldehyde (in methanol toxicity) has been
questioned (34).
No skeptic can overlook the fact that, metabolically, formaldehyde
must be formed as an intermediate to formic acid production (54).
Formaldehyde has a high reactivity which may be why it has not been
found in humans or other primates during methanol poisoning (59)....
If formaldehyde is produced from methanol and does have a
reasonable half life within certain cells in the poisoned organism
he chronic toxicological ramifications could be grave.
Formaldehyde is a known carcinogen (57) producing squanous-cell
carcinomas by inhalation exposure in experimental animals (22).
The available epidemiological studies do not provide adequate data
for assessing the carcinogenicity of formaldehyde in man (22, 24, 57).
However, reaction of formaldehyde with deoxyribonucleic acid
(DNA) has resulted in irreversible denaturation that could interfere
with DNA replication and result in mutation (37)..."
It is certain that high levels of aspartame use,
above 2 liters daily for months and years,
must lead to chronic formaldehyde-formic acid toxicity.
Fully 11 % of aspartame is methanol -- 1,120 mg aspartame
in 2 L diet soda, almost six 12-oz cans, gives 123 mg methanol
(wood alcohol). The methanol is immediately released
into the body after drinking .
Within hours, the liver turns much of the methanol into formaldehyde,
and then much of that into formic acid, both of which in time
are partially eliminated as carbon dioxide and water.
However, about 30 % of the methanol remains in the body
as cumulative durable toxic metabolites of formaldehyde
and formic acid -- 37 mg daily,
a gram every month, accumulating in and affecting every tissue.
If only 10 % of the methanol is retained daily as formaldehyde,
that would give 12 mg daily formaldehyde accumulation -- about
60 times more than the 0.2 mg from 10 % retention
of the 2 mg EPA daily limit for formaldehyde in drinking water.
Bear in mind that the EPA limit for formaldehyde in drinking water is
1 ppm, or 2 mg daily for a typical daily consumption of 2 L of water.

This long-term low-level chronic toxic exposure leads to typical
patterns of increasingly severe complex symptoms,
starting with headache, fatigue, joint pain, irritability, memory loss,
rashes, and leading to vision and eye problems, and even seizures.
In many cases there is addiction. Probably there are immune system
disorders, with a hypersensitivity to these toxins and other chemicals.

They found that about 70 % of the radioactive methanol in aspartame
put into the stomachs of 3 to 7 kg monkeys
was eliminated within 8 hours, with little additional elimination,
as carbon dioxide in exhaled air and as water in the urine.
They did not mention that this meant that about 30 % of the methanol
must transform into formaldehyde and then into formic acid,
both of which must remain as toxic products in all parts of the body.
They did not report any studies on the distribution of radioactivity
in body tissues, except that blood plasma proteins after 4 days
held 4 % of the initial methanol.
This study did not monitor long-term use of aspartame.
The low oral dose of aspartame and for methanol
was 0.068 mmol/kg, about 1 part per million [ppm]
of the acute toxicity level of 2,000 mg/kg, 67,000
mmol/kg, used by McMartin (1979).
Two L daily use of diet soda provides 123 mg methanol,
2 mg/kg for a 60 kg person, a dose of 67 mmole/kg,
a thousand times more than the dose in this study.
By eight hours excretion of the dose in air and urine had leveled off at
67.1 +-2.1 % as CO2 in the exhaled air
and 1.57+-0.32 % in the urine, so 68.7 % was excreted,
and 31.3 % was retained.
This data is the average of 4 monkeys.
"...the 14C in the feces was negligible."
"That fraction not so excreted (about 31%) was converted to body
constituents through the one-carbon metabolic pool."
"All radioactivity measurements were counted to +-1 % accuracy..."
This indicates that the results could not be claimed to have a precision of
a tenth of a percent. OK, so this is a nit-pick -- but I believe espousing
spurious accuracy is a sign of scientific insecurity.
The abstract ends, "It was concluded that aspartame was digested to
its three constituents that were then absorbed
as natural constituents of the diet.
Thus, the concept is very subtly insinuated that methanol, as a
constituent of aspartame, is absorbed as a natural constituent
of the diet.
Nowhere in this report are mentioned the dread words,
"formaldehyde" and "formic acid".
Of course, methanol and formaldehyde toxicity studies are highly
relevant to the issue of aspartame toxicity.
[ Aspartame has to be turned into its toxic products,
formaldehyde and formic acid, in the body, before it is toxic,
so some pro-aspartame reseach studies test aspartame outside the
body, and then proclaim that they have proved that it is not toxic. ]
