Aspartame was not approved until 1981, in dry foods. For over eight years the FDA refused to approve it because of the seizures and brain tumors this drug produced in lab animals. The FDA continued to refuse to approve it until President Reagan took office (a friend of Searle) and fired the FDA Commissioner who wouldn't approve it. Dr. Arthur Hull Hayes was appointed as commissioner. Even then there was so much opposition to approval that a Board of Inquiry was set up. The Board said: "Do not approve aspartame". Dr. Hayes OVERRULED his own Board of Inquiry. Shortly after Commissioner Arthur Hull Hayes, Jr., approved the use of aspartame in carbonated beverages, he left for a position with G.D. Searle's Public Relations firm. In a 1993 act that can only be described as "unconscionable", the FDA approved aspartame as an ingredient in numerous food items that would always be heated to above 86°degrees F (30°Degrees C). Much worse, on June 27th, 1996, without public notice, the FDA removed all restrictions from aspartame allowing it to be used in everything, including all heated and baked goods. In February of 1994, the U.S Department of Health and Human Services released the listing of adverse reactions reported to the FDA (DHHA 1994). Aspartame accounted for more than 75% of all adverse reactions reported to the FDA's Adverse Reaction Monitoring System (ARMS). That does not even account for the people who never report their problems to the FDA because they are unaware that Aspartame may be at fault.
When it comes to long-term damage aspartame appears to cause slow, silent damage in those unfortunate enough to not have immediate reactions and a reason to avoid it. It may take one year, five years, 10 years, or 40 years, but it seems to cause some reversible and some irreversible changes in health over long-term use.
METHANOL (AKA WOOD ALCOHOL/POISON) (10% OF ASPARTAME) Methanol/wood alcohol is a deadly poison. People may recall that methanol was the poison that has caused some "skid row" alcoholics to end up blind or dead. Methanol is gradually released in the small intestine when the methyl group of aspartame encounter the enzyme chymotrypsin. The absorption of methanol into the body is sped up considerably when free methanol is ingested. Free methanol is created from aspartame when it is heated to above 86 Fahrenheit (30 Centigrade). This would occur when aspartame-containing product is improperly stored or when it is heated (e.g., as part of a "food" product such as Jello). Methanol breaks down into formic acid and formaldehyde in the body. Formaldehyde is a deadly neurotoxin. An EPA assessment of methanol states 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." The recommend a limit of consumption of 7.8 mg/day. A one-liter (approx. 1 quart) aspartame-sweetened beverage contains about 56 mg of methanol. Heavy users of aspartame-containing products consume as much as 250 mg of methanol daily or 32 times the EPA limit. The most well known problems from methanol poisoning are vision problems. Formaldehyde is a known carcinogen, causes retinal damage, interferes with DNA replication, and causes birth defects. Due to the lack of a couple of key enzymes, humans are many times more sensitive to the toxic effects of methanol than animals. Therefore, tests of aspartame or methanol on animals do not accurately reflect the danger for humans. As pointed out by Dr Woodrow C. Monte, Director of the Food Science and Nutrition Laboratory at Arizona State University, "There are no human or mammalian studies to evaluate the possible mutagenic, teratogenic, or carcinogenic effects of chronic administration of methyl alcohol."
