[If aspartame only causes a 1% incidence of headache, then]

Probability of no event = 0.99.

Do it twice and the probability of it NOT happening the first time AND
it NOT happening the second time is 0.99 * 0.99 or 0.9801. Etc., etc.

The probability of nothing happening after 35 trials is

0.99 ^ 35 = 0.7034. [RM: So, there is a 70% chance of missing it in 35
trials, if it has a 1% chance of occurence each trial. In 70 trials,
there is 0.99 ^ 70 = .495 = 50% chance of missing it.]

The probability of of it happening one or more times is

1 - 0.7034 = 0.2966

In order to have a 95% probability of observing an event that has a 1%
chance of occurring, 298 trials are required. That is, the
probability of the event not happening in any trial [at all in the
whole series of 298 trials] is 0.99 ^ 298 = 0.05.

You do have to use the more complete form of the binomial distribution
if you want to calculate things like the probability the event occurs
exactly 1 time. The form I used above, P ^ n, is the correct form
for the event always occurring or never occurring.

Since the probability of harm not occurring is 0.99, and we want to
determine the number n for which the probability of harm not occurring
in a group of n aspartame users is <0.500, we have

0.99 ^ n ~= 0.500 or n ~= log(0.500)/log(0.99) which ~= 69.

So the aspartame consumer group must contain at least 69 people.

To have a 95% chance that at least one has been harmed (a 5% chance that

nobody was), we have n ~= log(0.05)/log(0.99) ~= 298.

Below I am forwarding an interesting off-list comment on my post of
yesterday:

From: AndyCutler@...
Date: Wed, 5 May 1999 17:34:20 EDT

In a message dated 99-05-05 06:30:54 EDT, you write:

>Of course, and this is probably the reason why smallish,

Even assuming that the study population has an equal incidence of the
problem in question (college students are great since they tend to be
healthier-- med students even more so), to have half a chance of
finding something that has a 1% incidence,
which is HUGE by public health standards,
you have to use 69 subjects. Very few studies are that
big-- and how many studies of 69 or more subjects have you seen that
didn't exclude one or more of them for some undefined reason?

[Murray: So, if aspartame harms only 1 of 100 people who use it, then
in order to have a 50% chance of showing it, we would have to compare
69 users vs 69 non-users-- then there would be a 50% chance that the
user group will have the 1 person harmed. That isn't great science,
especially considering that there is a large background incidence of
headaches.]

You need to use 229 subjects to have a 90% chance of finding that 1%
incidence problem.

[So, to have a 90% chance of showing it is a non-chance effect, we
would have to compare 229 users vs 229 non-users-- then there would
be a 90% chance that the user group would have the 1 person harmed.
In other words, there would be only a 10% chance that the non-user
group might have the the 1 person harmed, if aspartame is actually
harmful. This is far more users than most double-blind tests of
aspartame, which use 12 to 50 subjects.]

You need to use 298 subjects to have a 95% chance of finding that 1%
incidence problem-- and "95% confidence" is the usual level of
certainty medical research bozos cite in deciding whether to pay
attention to a problem. Thus no study on aspartame containing less
than 298 subjects (without any leaving the study) is valid for
asserting that less than 1% of the population is having adverse effects
from it.

[About 200 million use aspartame in the USA. A 1% incidence of harm
means 2 million cases. So, there has never been any experimental test
of aspartame toxicity that eliminates the possibility that there are
about 2 million people harmed in the USA, with reported symptoms
ranging from headaches to seizures to brain tumors.]

You need 458 subjects to have a 99% chance of finding that 1% incidence
problem.

You want 95% confidence for a 0.1% problem? E. g. that something like
5-10 thousand Swedes will fall over dead from drinking the stuff? That
takes a study enrolling 2994 people ALL OF WHOM are accounted for as
results at the end. Lots of universities aren't BIG enough to get that
many students to enroll in a study like this!

Per - maybe you should share this with your list? Putting some numbers
to it often makes things more obvious. <end of forwarded message>
Per Dalen <per.dalen@...>

[More comments by Rich Murray] Think of all the things that can go
wrong in the typical double-blind study, in which neither the
subjects, often intelligent, rambunctious young healthy college
students, nor the scientists are supposed to know which pill is the
drug and which is the inert placebo. For one thing, the subjects are
constantly exposed to aspartame in things like yogurt, chewing gum,
and many medicines. All the subject has to do is to open or bite
the capsule to find if it is inert or not, or just notice if he feels
something from the pill or not. If he finds that he is taking the
aspartame, and gets a headache, and happens to be getting, say $ 50 a
day for the study, and the scientist seems to look grumpy when he tells
about the headache, then the subject is motivated to pretend to take
the aspartame, to pretend he doesn't get headaches,
and to take aspirin every day.
One subject like that is enough to invalidate the chance of
proving with 95% confidence, with 298 subjects exposed to aspartame,
that aspartame has a 1 in 100 incidence of harm. How much do you
trust college students? And what about the scientists? Are they going
to report results that put a quick end to their lavish funding by
industry? Is the industry going to publish any negative findings?
Isn't the industry going to praise, publish, and fund the teams that
get the desired results?
So all the furor for decades, testing aspartame
and a host of other things with elaborate double-blind experimental
studies is only proving that fundamental law of society: money talks.]

Neuroepidemiology 1993;12(3):179-94
Epidemiology of migraine.
Silberstein SD, Lipton RB
Comprehensive Headache Center, Germantown Hospital and Medical Center,
Philadelphia, Pa.
Migraine epidemiology presents methodological challenges, partially
simplified by the use of the new International Headache Society (IHS)
Classification. Most previously published migraine studies were
clinic-based, which introduces bias since less than 5% of migraineurs
consult specialists. A series of population-based studies of migraine
prevalence and incidence, based on the new operational IHS criteria,
are now available and are reviewed,
along with the migraine personality, comorbid psychiatric
conditions and neuropsychological impairment.
Migraine headaches are now divided into those with aura (classic
migraine) and those without aura (common migraine). Headache occurs in
about 91% of men and 96% of women, migraine occurs in about 6% of men
and 18% of women (one-year prevalence). Migraine is most common in the
third decade of life and in lower socioeconomic groups.
It is associated with an increased prevalence of depression and panic
attacks. PMID: 8272178, UI: 94097472

This raises more fundamental issues. If headache occurs in 91% of men
and 96% of woman at least once a year, especially in the many subjects
who are college-age, then, as is common knowledge, there is a great
background incidence of headaches, making it even more dicey to test
for the effects of aspartame, if the incidence of headache is 1% for
aspartame users. Some of the studies here merely count together the
percent of all subjects who report some headaches during up to 6 months
of daily aspartame use, without reporting the actual total of headaches
and the distribution in time of headaches for each subject. In most
toxic processes, some people are far more vulnerable than others, and
this vulnerability can change, decreasing due to developing tolerance,
increasing if the toxin is cumulative. It is a public relations ploy,
not science for the common welfare, to not present the actual specific
raw data, and not give an adaquate analysis of whether certain subjects
have the most symptoms, which symptoms cluster together, and which
symptoms increase with time, along with foolproof tests that the test
subjects are actually taking their doses, whether the subjects were
actually avoiding aspartame in their daily diets, whether use of
pain medications like aspirin increased, and, very fundamentally,
ensuring that a complete symptom check list was recorded every day--
all failings in an often-cited study by Leon et al in 1989. But, first
we review three studies that support one another in displaying the
striking reality of high incidence of aspartame toxicity.

Headache 1988 Feb;28(1):10-4
The effect of aspartame on migraine headache.

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.

Safety of long-term large doses of aspartame

Safety of long-term administration of 75 mg/kg of aspartame per day was
evaluated with the use of a randomized, double-blind,
placebo-controlled, parallel-group design in 108 male and female
volunteers aged 18 to 62 years. Subjects received either aspartame or
placebo in capsule form three times daily for 24 weeks. No persistent
changes over time were noted in either group in vital signs; body
weight; results of standard laboratory tests; fasting blood levels of
aspartame's constituent amino acids (aspartic acid and phenylalanine),
other amino acids, and methanol; or blood formate levels and 24-hour
urinary excretion of formate. There also were no statistically
significant differences between groups in the number of subjects
experiencing symptoms or in the number of symptoms per subject. These
results further document the safety of the long-term consumption of
aspartame at doses equivalent to the amount of aspartame in
approximately 10 L of beverage per day.

Summary of Aspartame Methanol/Formaldehyde Toxicity
"These are indeed extremely high levels for adducts of formaldehyde, a
substance responsible for chronic deleterious effects that has also
been considered carcinogenic....
"It is concluded that aspartame consumption may constitute a hazard
because of its contribution to the formation of formaldehyde adducts."
(Trocho 1998)

"It was a very interesting paper, that demonstrates that formaldehyde
formation from aspartame ingestion is very common and does indeed
accumulate within the cell, reacting with cellular proteins (mostly
enzymes) and DNA (both mitochondrial and nuclear). The fact that it
accumulates with each dose, indicates grave consequences among those
who consume diet drinks and foodstuffs on a daily basis." (Blaylock
1998)

Methanol from aspartame is released in the small intestine when the
methyl group of aspartame encounters the enzyme chymotrypsin (Stegink
1984, page 143). A relatively small amount of aspartame (e.g., one can
of soda ingested by a child) can significantly increase plasma methanol
levels (Davoli 1986a).

Clinically, chronic, low-level exposure to methanol has been seen to
cause headaches, dizziness, nausea, ear buzzing, GI distiurbances,
weakness, vertigo, chills, memory lapses, numbness & shooting pains,
behavioral disturbances, neuritis, misty vision, vision tunneling,
blurring of vision, conjunctivitis, insomnia, vision loss, depression,
heart problems (including disease of the heart muscle), and pancreatic
inflammation (Kavet 1990, Monte 1984, Posner 1975).

The methanol from aspartame is converted to formaldehyde and then
formic acid (DHHS 1993, Liesivuori 1991), although some of the
formaldehyde appears to accumulate in the body as discussed above.
Chronic formaldehyde exposure at very low doses
has been shown to cause immune system and
nervous system changes and damage as well as headaches,
general poor health, irreversible genetic damage, and a number of other
serious health problems (Fujimaki 1992, He 1998, John 1994, Liu 1993,
Main 1983, Molhave 1986, National Research Council 1981, Shaham 1996,
Srivastava 1992, Vojdani 1992, Wantke 1996). One experiment
(Wantke 1996) showed that chronic exposure to formaldehyde caused
systemic health problems (i.e., poor health) in children at an air
concentration of only 0.043 - 0.070 parts per million!

Obviously, chronic exposure to an extremely small amount of
formaldehyde is to be avoided.
Even if formaldehyde adducts did not build up in the
body from aspartame use, the regular exposure to excess levels of
formaldehyde would still be a major concern to independent scientists
and physicians familiar with the aspartame toxicity issue.

In addition to chronic formaldehyde poisoning, the excitotoxic
amino acid derived from aspartame will almost certainly worsen the
damage caused by the formladehyde. Synergistic effects from aspartame
metabolites are rarely, if ever, mentioned by the manufacturer.
Aspartame breaks down into a free-form (unbound to protein) excitotoxic
amino acid which is quickly absorbed (as long as it is not given in
slowly dissolving capsules) and can raise the blood plasma levels of
this excitotoxin (Stegink 1987). It is well known that free-form
excitotoxins can cause irreversible damage to brain cells
(in areas such as the retina, hypothalamus, etc.)
in rodents and primates (Olney 1972, Olney 1980,
Blaylock 1994, Lipton 1994). In order to remove excess,
cell-destroying excitotoxic amino acids from extracellular space, glial
cells surround the neuron and supply them with energy (Blaylock 1994,
page 39, Lipton 1994). This takes large amounts of ATP. However,
formate, a formaldehyde metabolite, is an ATP inhibitor
(Liesivuori 1991). Eells (1996b) points out that excitatory amino acid
toxicity may be the "mediators of retinal damage secondary to formate
induced energy depletion in methanol-intoxication." The synergistic
effects from the combination of a chronic formaldehyde exposure from
aspartame along with a free-form excitotoxic amino acid is extremely
worrisome.

It appears that methanol is converted to formate in the eye
(Eells 1996a, Garner 1995, Kini 1961). Eells (1996a) showed that
chronic, low-level methanol exposure in rats led to formate
accumulation in the retina of the eye.
More details about chronic Methanol /Formaldehyde
poisoning from aspartame can be found on the
Internet at http://www.holisticmed.com/aspartame/aspfaq.html.

How did the manufacturer convince scientists and physicians that it is
"safe" to be exposed regularly to low levels of an exceptionally toxic
poison? Answer: Deceptive research and deceptive statements!

Hiding the Blood Plasma Methanol Increase From Aspartame Ingestion
On February 22, 1984, the acting FDA Commissioner, Mark Novitch stated
(Federal Register 1984):

"... aspartame showed no detectable levels of methanol in the
blood of human subjects following
the ingestion of aspartame at 34 mg/kg...."

The American Medical Association repeated this statement one year later
(AMA 1985). This statement was repeated in American Family Physician in
1989 (Yost 1989). Shaywitz (1994) stated that there was no detectable
levels of methanol in the blood after aspartame administration.
Puthrasingam (1996) stated that methanol from aspartame is

"undetectable in peripheral blood or even in portal blood."

All of these statements were very convincing... and very wrong! The
statements were based on aspartame industry research which used an
outdated plasma methanol measuring test (Baker 1969).
The test they used had a limited of methanol detection of 4 mg/l.
However, Cook (1991)
measured an average baseline (unexposed) methanol level of ~0.6 mg/l.
Others (Davoli 1986, d'Alessandro 1994, Osterloh 1996) have measured an
average baseline methanol level of close to 1 mg/l. This means that a
person's methanol levels would have to rise 350% to 600% before an
increase would have been noticed by the industry researchers using this
outdated test! An increase of less than 350% to 600% appeared as no
increase at all!

Probably only a handful of people in the world would have noticed that
by using a plasma methanol measuring test with limits of 4 mg/l, they
avoided seeing an methanol level increase -- even though there was a
large increase. Below are some of the experiments which used the
inappropriate methanol measuring technique.

Stegink 1990 8 hourly doses

lower limit of their methanol test.

Hertelendy 1993 15 mg/kg 4 mg/l ...

Shaywitz 1993 34 mg/kg 4 mg/l ...

Shaywitz 1994 34 mg/kg 4 mg/l ...

Note: 10 mg/kg is approximately a one liter bottle of diet soda for a
60 kg adult and 1.5 cans of diet soda for a 30 kg child. Children with
aspartame freely-available can ingest between 27 mg/kg - 77 mg/kg
(Frey 1976) and adult dieters have been shown to ingest between 8 mg/kg
and 36 mg/kg (Porikos 1984).

In 1986, Davoli (1986a) published a study which showed that 6 mg/kg
to 8.7 mg/kg of aspartame could significantly raise the plasma methanol
levels. The methanol levels nearly doubled in some cases. While
there were some logical errors in Davoli's conclusion
(discussed below), the study proved that
by using a reasonable methanol testing method,
plasma methanol levels will increase from a relatively low dose of
aspartame ingestion. The methanol measuring technique used by Davoli
was published in 1985 (Davoli 1986b) and was sensitive to 0.012 mg/l.

Other researchers have used sensitive plasma methanol measurement
techniques. d'Alessandro (1994) measured plasma methanol levels in
humans well below 1 mg/l. Cook (1991) used a methanol test developed in
1981 to measure methanol plasma methanol levels in humans below
0.5 mg/l.

What did industry scientists know or should have known?

1.They knew and admited that their methanol testing procedure developed
in 1969 was not sensitive enough to detect the large increases of
plasma methanol levels when aspartame was given at doses of 34 mg/kg
(Stegink 1984b).

2.They must have been aware that Davoli found methanol levels increase
significantly when aspartame was given
at doses of 6 mg/kg to 8.7 mg/kg. To believe that they
were not aware of this, one has to believe that
none of the researchers choose to or knew how to conduct a simple
Medline database search.

3.They should have known that there were several legitimate plasma
methanol measurement techniques developed since 1969. Given that they
admited their technique was not appropriate for aspartame doses of less
than 34 mg/kg (Stegink 1984b), they should have at least looked to find
an appropriate test.

4.Given that Leon (1989) was aware enough to test for formate levels,
he must have been aware that all of the methanol from aspartame would
have already converted to formaldehyde after a 12-hour fast.

I believe that Monsanto/NutraSweet and the aspartame industry are
clearly taking advantage of physicians and scientists who lack the time
to carefully investigate each number in a study to see if there is
deception. While these actions may not amount to "scientific fraud," it
does amount to an abuse of the scientific method in my opinion.
[end of quote from Gold]

Returning to Leon's study of headaches and other symptoms, the subjects
were every three weeks (+- 1 week) for 24 weeks, given in a clinic
their supply of pills and thorough medical tests,
and interviewed about any symptoms:
"Subjects were asked at each visit about any unusual symptoms
since the previous visit. Elicited symptoms were classified on the
basis of the World Health Organization terminology."
"The coded adverse experiences fell into
72 terms in 14 World Health Organization
(Geneva, Switzerland) organ-systems categories." Of the 108 original
volunteers, 101 completed, 51 placebo, and 50 aspartame. "Of the 108
original subjects, 90 (83%) reported 72 different complaints, grouped
into 14 World Health Organization organ-system categories, during the
course of this 6-month study.
There were a total of 193 symptoms in the aspartame group
and 130 in the placebo group. Most of the reported
symptoms were mild or moderate. There were no visual complaints in
either group or ocular findings on physical examination. The most
common complaints in each group were headaches, upper repiratory tract
symnptoms, and abdominal pain. No consistent pattern of occurrence was
noted in these or any other symptoms, nor were there any statistically
significant differences between groups in number of subjects
experiencing these symptoms or in number of symptoms per subject.
There was no statistically significant differerences in the incidence
of headaches (the most commonly reported complaint) in the aspartame
group compared with the placebo group. Figure 3 shows the frequency of
headaches for each group during the course of the study. The pattern
displayed here of sporadic fluctuations in incidences of headache in
each group was similar to that seen with the other common symptoms."

So, no list of symptoms or daily totals of symptoms for each subject--
just recollections every three weeks, "unusual symptoms", "elicited
symptoms".

Isn't this wonderful? Doesn't that sonorous phrase "World Health
Organization" just lull your jaded synapses into sleep-- but wait,
just how much was never recorded in the first place, in these
interviews of busy students, faculty and staff, every three weeks?
After all, one of the most common case complaints for decades is--
impaired memory!
How well are people going to remember, weeks later,
humiliating episodes of confusion, mind fog, anxiety, depression,
anger, insomnia, or report gradually increasing
fatigue, subtle retreats from activity, academic dissappointments?
And what data there is is not given--
only the reassuring mantra, "no statistically significant
differences", in unreassuring contrast to the stark, dramatic, and
chaotic results of the independent studies, which used lower doses for
far shorter periods. Some subjects must have tossed their capsules in
the can, not their mouths, and collected their pay-- how much, by the
way? Others must have taken up daily doses of aspirin and the like.
The redoubtable Table 3 shows a
decrease from about 8 aspartame subjects with
headaches in the first 3-week period to about 4 in each of the
last four three-week periods: 8, 4, 7, 7, 5, 5, 4, 4 -- this is in
absolute contradiction with the three independent studies.

The placebo subjects actually reported a rise in people with headaches:
4, 2, 6, 7, 1, 5, 6, 11 . The senior authors, Leon and Hunninghake,
are invited to render a public service to science by releasing their
raw data on symptoms.
