formaldehyde & formic acid from methanol in aspartame:
Murray: 12.9.2 rmforall
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, since 11% of aspartame (1,120 mg in 2L diet soda, 5.6 12-oz
cans) is 123 mg methanol (wood alcohol), immediately released into the
body after drinking (unlike the large levels of methanol locked up in
molecules inside many fruits), then quickly transformed into
formaldehyde, which in turn becomes formic acid, both of which in
time become 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.
If 10% of the methanol is retained 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
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.
RTM: ATSDR: EPA limit 1 ppm formaldehyde in drinking water July 1999
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, 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.

BACKGROUND: Fibromyalgia is a common rheumatologic disorder that is
often difficult to treat effectively.
CASE SUMMARY: Four patients diagnosed with fibromyalgia syndrome
for two to 17 years are described.
All had undergone multiple treatment
modalities with limited success. All had complete, or nearly complete,
resolution of their symptoms within months after eliminating monosodium
glutamate (MSG) or MSG plus aspartame from their diet.
All patients were women with multiple comorbidities
prior to elimination of MSG.
All have had recurrence of symptoms whenever MSG is ingested.

They found that about 70% of the radioactive methanol in aspartame put
into the stomachs of 3 to 7 kg monkeys was eliminated within a day 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, much 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 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
"Fruit and vegetables contain pectin with variable methyl ester
content. However, the human has no digestive enzymes for pectin (6, 25)
particularly the pectin esterase required
for its hydrolysis to methanol (26).
Fermentation in the gut may cause disappearance of pectin (6) but the
production of free methanol is not guaranteed by fermentation (3). In
fact, bacteria in the colon probably reduce methanol directly to formic
acid or carbon dioxide (6) (aspartame is completely absorbed before
reaching the colon). Heating of pectins has been shown to cause
virtually no demethoxylation; even temperatures of 120 deg C produced
only traces of methanol (3). Methanol evolved during cooking of high
pectin foods (7) has been accounted for in the volatile fraction during
boiling and is quickly lost to the atmosphere (49).
Entrapment of these volatiles probably accounts for the elevation in
methanol levels of certain fruit and vegetable products
during canning (31, 33)."
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
Formaldehyde has a high reactivity which may be why it
has not been found in humans or other primates during methanol
If formaldehyde is produced from methanol and does have a reasonable
half life within certain cells in the poisoned organism the chronic
toxicological ramifications could be grave.
Formaldehyde is a known
carcinogen (57) producing squamous-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

"...the total amount of methanol absorbed will be approximately
10% of aspartame ingested. An EPA assessment of methanol states
that methanol, 'is considered a cumulative poison due to the low rate
of excretion once it is absorbed. The absorbed methanol is then
slowly converted to formaldehyde...'"
