three independent double-blind experiments on aspartame and headache in
1988, 1993, 1994: Murray 2005.06.04
These links provide detailed summaries of studies in 1988, 1993, and 1994
that are not funded by the aspartame industry, are experimental studies
published in mainstream peer-reviewed journals, and that largely agree with
each other in showing a very high percentage of people with headache and
other typical symptoms for a daily use of aspartame in capsules for test
periods of 1 to 4 weeks.
As far as I know, never in three decades has any study in humans also made
specific biochemical tests to show how the three components, which are
rather independently and freely absorbed via the GI tract, accumulate in and
affect specific cells and tissues in people who display headache and the
other commonly reported symptoms, and who prima facie are in more vulnerable
groups.
So, basically, despite the 786 studies since 1973 listed for aspartame in
PubMed, there is no adequate information on the basic biochemical realities
of the disposition and toxicity of the three components in humans.
To quickly do a few such exhaustive workups on a few people would be
extremely valuable as pilot studies. Perhaps insurance could pay the costs
for diagnostic tests, measurements, and imaging.
In view of the urgency of dealing with long-neglected public heath problems
of largely unknown nature and scope, the results of such pilot studies might
best be put in full detail on the Net, with an open, moderated forum for
civil debate and feedback.
The results would illuminate cases of chronic, long-term exposure to
methanol (formaldehyde, formic acid) from many other sources: medical
education and practice, morticians, dark wines and liquors, tobacco, wood
smoke, vehicle exhaust, new buildings and mobile homes, and degradation by
bacteria in the colon of pectins from fruits and vegetables.

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). If 30% of
the methanol is turned into formaldehyde, the amount of formaldehyde is 18
times the USA EPA limit for daily formaldehyde in drinking water, 2 mg in 2
L water.

They conducted a double-blind study of patients, ages 18-55, who had
a medical diagnosis of classical migraines (normally having 1-3
migraines in 4-weeks), who were not on medications (other than
analgesics), and who suspected that aspartame had a negative effect on
their migraine headaches. The subjects were given 1200 mg daily,
aspartame or placebo, for four weeks, about 17 mg/kg. The placebo
group had no increase in headaches. Approximately half of the subjects
(5 of 11) who took aspartame had a large, statistically significant
(p = 0.02), increase in migraine headache frequency, but not in
intensity or duration, compared to baseline or placebo. Only 11 of
25 subjects completed the program: 8 dropped out, 4 began new
medications, 2 had incomplete records. They were at home.
Since 1/3 of the subjects dropped out, they may have been choosing
to avoid headaches-- were they unpaid? To achieve statistical
signifance with only 11 subjects hints that the incidence rate from
aspartame is very high, about 1/2, for migraine cases who believe
that they are hurt by aspartame.

Eight depressed patients, ages 24-60, and five non-depressed controls,
ages 24-56, employed at the hospital, were given for 7 days either
aspartame or a placebo, and then after a 3 day break, given the
opposite. Each got 2100 mg aspartame daily, 30 mg/kg bodyweight,
equal to 10-12 cans of diet soda daily, about a gallon. Despite the
very small number of subjects, the results were dramatic and
statistically significant. The eight depressed patients reported with
aspartame, compared to placebo, much higher levels of nervousness,
trouble remembering, nausea, depression, temper, and malaise. (For each
symptom, p<0.01) The five normals did not report strong enough
differences between aspartame and placebo to be significant.
Initially, the study was to be on a group of 40, but was halted by the
Institutional Review Board because of severe reactions among 3 of the
depressed patients.
Again, statistical significance with only 8 depressed patients:
"In this study, patients most often began to report significant
symptoms after day 2 or 3." The incidence rate is very high,
indeed, about 1/3. The most common symptoms are entirely typical
of thousands of case histories.

In their introduction, they comment:
"In addition, the FDA had received over 5,000 complaints as of July,
1991 in a passive surveillance system to monitor adverse side effects.
(17) Neurologic problems constitute the primary complaints in these
and several other case series, with headaches accounting for
18 to 45 %,depending on the case series reported. (17-19)"
Subjects, ages 18-57, were recruited who believed they got headaches
from aspartame, but were otherwise mentally and physically healthy.
They were paid $ 15 total, and were at home. Of the 44 subjects, 32
contributed data to the 38-day trials: a week of inert placebo, a week
of either aspartame or placebo, followed by a week of the opposite, and
then this two-week cycle repeated. The daily dose was about 30 mg/kg.
"The proportion of days subjects reported having a headache was
higher during aspartame treatment compared with placebo treatment
(aspartame = 0.33, placebo = 0.24; p = 0.04) (table 5)".
Of the 12 subjects not included in the data, 7 reported adverse
symptoms before withdrawing.
Again, statistical significance with a moderate number of healthy
subjects, willing to be recruited by a newspaper ad, who believed
aspartame hurt them. The number of headaches for each subject
for each treatment week are given: it appears that 4 subjects
had the strongest increase in headaches from the run-in week
or placebo week to their first week on aspartame, jumping from 0 to 5,
1 to 6, 1 to 4, 0 to 5 headaches per week. So, about 4 of the 44
healthy people recruited for the study, who believed aspartame hurt
them, had a stong increase in headaches from the first week of daily
asparame exposure, while 7 reported adverse symptoms before leaving,
a total of 11 out of 44, an incidence ratio of 1/4.
This is sky high, if we consider that, if the incidence ratio for the
about two hundred million users in the USA is 1 of 100, that is 2
million cases. It is plausible that the incidence ratio lies between 1
and 10 out of 100 for continuous daily exposure. These three flames
should have set off alarm bells, with extensive follow-up studies and
much more careful study of thousands of case histories. But these
little flares were adroitly smothered by thick blankets of industry
funded fluff:
