Aspartame


Aspartame is the technical name for the brand names, NutraSweet, Equal, Spoonful, and Equal-Measure. Aspartame was discovered by accident in 1965, when James Schlatter, a chemist of G.D. Searle Company was testing an anti-ulcer drug. Aspartame was approved for dry goods in 1981 and for carbonated beverages in 1983. (Actually, it was originally approved for dry goods on July 26, 1974, but objections filed by neuroscience researcher Dr. John W. Olney and Consumer attorney James Turner in August 1974 as well as investigations of G.D. Searle's research practices caused the FDA to put approval of aspartame on hold). In 1985, Monsanto purchased G.D. Searle and made Searle Pharmaceuticals and The NutraSweet Company separate subsidiaries.
Aspartame is, by far, the most dangerous substance on the market that is added to foods. Aspartame accounts for over 75 percent of the adverse reactions to food additives reported to the U.S. Food and Drug Administration (FDA). Many of these reactions are very serious including seizures and death as recently disclosed in a February 1994 Department of Health and Human Services report.

Parkinson's Disease
Alzheimer's
Lymphoma
Birth defects
Fibromyalgia
Diabetes


Aspartame is made up of three chemicals, aspartic acid, phenylalanine, and methanol. The book, "Prescription for Nutritional Healing" by James and Phyllis Balch lists aspartame under the category of "Chemical Poison." As you shall see, that is exactly what it is. Aspartic Acid (40% of aspartame) & Glutamic acid (99% of MSG) ------------------------------------------------------------- Dr. Russell L. Blaylock, a professor of Neurosurgery at the Medical University of Mississippi, recently published a book thoroughly detailing the damage that is caused by the ingestion of excessive aspartic acid from aspartame and glutamic acid from MSG. Dr. Blaylock uses almost 500 scientific references to prove how excess free excitatory amino acids such as aspartic acid and glutamic acid in our food supply are causing serious chronic neurological disorders and a myriad of other acute symptoms.
[3] Summary of How Glutamate and Aspartate Cause Damage --------------------------------------------------- Aspartate and glutamate act as neurotransmitters in the brain by facilitating the transmittion of information from neuron to neuron. Too much aspartate or glutamate in the brain kills certain neurons by allowing the influx of too much calcium into the cells. This influx triggers excessive amounts of free radicals which kill the cells. The neural cell damage that can be caused by excessive aspartate and glutamate is why they are referred to as "excitotoxins." They "excite" or stimulate the neural cells to death. Aspartic acid is an amino acid. Taken in its free form (unbound to proteins) it significantly raises the blood plasma level of aspartate and glutamate. The excess aspartate and glutamate in the blood plasma shortly after ingesting aspartame or products with free glutamic acid (glutamate precursor) leads to a high level of those neurotransmitters in certain areas of the brain. The blood brain barrier (BBB) which normally protects the brain from excess glutamate and aspartate as well as toxins 1) is not fully developed during childhood, 2) does not fully protect all areas of the brain, 3) is damaged by numerous chronic and acute conditions, and 4) allows seepage of excess glutamate and aspartate into the brain even when intact. The excess glutamate and aspartate slowly begin to destroy neurons. The large majority (75%+) of neural cells in a particular area of the brain are killed before any clinical symptoms of a chronic illness are noticed. A few of the many chronic illnesses that have been shown to be contributed to by long-term exposure excitatory amino acid damage include:

MS
ALS
Memory Loss
Hormonal Problems
Hearing Loss
Epilepsy
Alzheimer's Disease
Parkinson's Disease
Hypoglycemia
AIDS Dementia
Brain Lessions
Neuroendocrine Disorders

The risk to infants, children, pregnant women, the elderly, and persons with certain chronic health problems from excitotoxins are great. Even the Federation of American Societies For Experimental Biology (FASEB), which usually understates problems and mimmicks the FDA party-line, recently stated in a review that "it is prudent to avoid the use of dietary supplements of L-glutamic acid by pregnant women, infants, and children. The Existence of evidence of potential endocrine responses, i.e., elevated cortisol and prolactin, and differential responses between males and females, would also suggest a neuroendocrine link and that supplemental L-glutamic acid should be avoided by women of childbearing age and individuals with affective disorders."
[4] Aspartic acid from aspartame has the same deleterious effects on the body as glutamic acid. The exact mechanism of acute reactions to excess free glutamate and aspartate is currently being debated. As reported to the FDA, those reactions include
[5]:

Headaches/Migraines
Nausea
Abdominal Pains
Fatigue (blocks sufficient glucose entry into brain)
Sleep Problems
Vision Problems
Anxiety attacks
Depression
Asthma/Chest Tightness


One common complaint of persons suffering from the effect of aspartame is memory loss. Ironically, in 1987, G.D. Searle, the manufacturer of aspartame, undertook a search for a drug to combat memory loss caused by excititory amino acid damage. Dr. Blaylock is one of many scientists and physicians who are concerned about excititory amino acid damage caused by ingestion of aspartame and MSG. A few of the many experts who have spoken out against the damage being caused by aspartate and glutamate include: - Adrienne Samuels, Ph.D. -- an experimental Psychologist specializing in research design. - John W. Olney, MD -- a Professor in the Department of Psychiatry, School of Medicine, Washington University. He is a Neuroscientist and researcher, and one of the world's foremost authorities on excitotoxins. (He informed Searle in 1971 that aspartic acid caused holes in the brain of mice.) - Francis J. Waickman, MD -- a recipient of the Rinkel and Forman Awards and Board certified in Pediatrics, Allergy and Immunology. - John R. Hain, MD -- Board Certified Forensic Pathologist - H.J. Roberts, MD, FACP, FCCP -- Diabetic Specialist, Who's Who in American, The World, Science and Technology, and selected by a national medical publication as "The Best Doctor in the U.S." - John Samuels -- Compiled a listed of scientific research sufficient to show the dangers of ingesting excess free glutamic and aspartic acid. ... and many more. Phenylalanine (50% of aspartame) ------------------------------- Phenylalanine is an amino acid normally found in the brain. Persons with the genetic disorder, phenylketonuria (PKU) cannot metabolize phenylalanine. This leads to dangerously high levels of phenylalanine in the brain (sometimes lethal). It has been shown that ingesting aspartame, especially along with carbohydrates can lead to excess levels of phenylalanine in the brain even in persons who do not have PKU. This is not just a theory, as many people who have eaten large amounts of aspartame over a long period of time and do not have PKU have been shown to have excessive levels of phenylalanine in the blood. Excessive levels of phenylalanine in the brain can cause the levels of seratonin in the brain to decrease, leading to emotional disorders such as depression. It was shown in human testing that phenylalanine levels of the blood were increased significantly in human subjects who chronically used aspartame.
[6] Even a single use of aspartame raised the blood phenylalanine levels. In his testimony before the U.S. Congress, Dr. Louis J. Elsas showed that high blood phenylalanine can be concentrated in parts of the brain, and is especially dangerous for infants and fetuses. He also showed that phenylalanine is metabolised much more effeciently by rodents than by humans.
[7] One account of a case of extremely high phenylalanine levels caused by aspartame was recently published the the "Wednesday Journal" in an article entitled "An Aspartame Nightmare." John Cook began drinking 6 to 8 diet drinks every day. His symptoms started out as memory loss and frequent headaches. He began to crave more aspartame-sweetened drinks. His condition deteriorated so much that he experienced wide mood swings and violent rages. Even though he did not suffer from PKU, a blood test revealed a phenylalanine level of 80 mg/dl. He also showed abnormal brain function and brain damage. After he kicked his aspartame habit, his symptoms improved dramatically.
[8] As Dr. Blaylock points out in his book, early studies measuring phenylalanine buildup in the brain were flawed. Investigators who measured specific brain regions and not the average throughout the brain notice significant rises in phenylalanine levels. Specifically the hypothalamus, medulla oblongata, and corpus striatum areas of the brain had the largest increases in phenylalanine. Dr. Blaylock goes on to point out that excessive buildup of phenylalanine in the brain can cause schizophrenia or make one more susceptible to seizures. Therefore, long-term, excessive use of aspartame may provided a boost to sales of seratonin reuptake inhibitors such as Prozac and drugs to control schizophrenia and seizures. Methanol (aka wood alcohol/poison) (10% of aspartame) ----------------------------------------------------- Methanol/wood alcohol is a deadly poison. Some people may remember methanol as 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.
[9] Symptoms from methanol poisoning include headaches, ear buzzing, dizziness, nausea, gastrointestinal disturbances, weakness, vertigo, chills, memory lapses, numbness and shooting pains in the extremities, behavioral disturbances, and neuritis. The most well knowm problems from methanol poisoning are vision problems including misty vision, progressive contraction of visual fields, blurring of vision, obscuration of vision, retinal damage, and blindness. Formaldehye is a known carcinogen, causes retinal damage, interferes with DNA replication, causes birth defects.
[10] 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."
[11] He was so concerned about the unresolved safety issues that he filed suit with the FDA requesting a hearing to address these issues. He asked the FDA to "slow down on this soft drink issue long enough to answer some of the important questions. It's not fair that you are leaving the full burden of proof on the few of us who are concerned and have such limited resources. You must remember that you are the American public's last defense. Once you allow usage (of aspartame) there is literally nothing I or my colleagues can do to reverse the course. Aspartame will then join saccharin, the sulfiting agents, and God knows how many other questionable compounds enjoined to insult the human constitution with governmental approval."
[10] Shortly thereafter, the Commissioner of the FDA, Arthur Hull Hayes, Jr., approved the use of aspartame in carbonated beverages and then left for a position with G.D. Searle's Public Relations firm.
[11] It has been pointed out that some fruit juices and alcoholic beverages contain small amounts of methanol. It is important to remember, however, that methanol never appears alone. In every case, ethanol is present, usually in much higher amounts. Ethanol is an antidote for methanol toxicity in humans.
[9] The troops of Desert Storm were "treated" to large amounts of aspartame-sweetened beverages which had been heated to over 86 F in the Saudi Arabian sun. Many of them returned home with numerous disorders similar to what has been seen in persons who have been chemically poisoned by formaldehyde. The free methanol in the beverages may have been a contributing factor in these illnesses. 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 F (30 C).

Diketopiperazine (DKP) ---------------------- DKP is a breakdown product of aspartame. DKP has been implicated in the occurance of brain tumors. Dr. John Olney noticed that DKP, when nitrosated in the gut, produced a compound which was similar to N-nitrosourea, a powerful brain tumor causing chemical. G.D. Searle conducted animal experiments on the safety of DKP. The FDA found numerous experimental errors occured, including "clerical errors, mixed-up animals, animals not getting drugs they were supposed to get, pathological specimens lost because of improper handling," and many other errors.
[12] These sloppy laboratory procedures may explain why both the test and control animals had sixteen times more brain tumors than would be expected in experiments of this length. Here is some breakdown info: Date of 6 Months 36 Months Bottling After After Bottling Bottling Aspartame 550.0 mg 155.34 mg 19.70 mg L-phenylalanine methyl ester 0.0 mg 28.62 mg 13.01 mg DKP 0.0 mg 135.66 mg 173.28 mg L-aspartylphenylalanine 0.0 mg 158.31 mg 189.05 mg L-phenylalanine 0.0 mg 42.22 mg 101.27 mg Reference --------- Tsang, Wing-Sum, et al., 1985. "Determination of Aspartame and Its Breakdown Products in Soft Drinks by Reverse- Phase Chromatography with UV Detection," Journal Agriculture and Food Chemistry, Vol. 33, No. 4, page 734- 738. In an ironic twist, shortly after these experimental errors were discovered, the FDA used guidelines recommened by G.D. Searle to devlop the Industry-wide FDA standards for Good Laboratory Practies.[11] DKP has also been implicated as a cause of uterine polyps and changes in blood cholesterol by FDA Toxicologist Dr. Jacqueline Verrett in her testimony before the U.S. Senate.
[13] ---------------------- The components of aspartame can lead to a wide variety of ailments. Some of these problems occur gradually, others are immediate, acute reactions. There is an enormous population of people who are suffering from symtpoms contributed to by aspartame, yet they have no idea why herbs or drugs are not helping relieve their problems. There are other users of aspartame who *appear* not to be suffering immediate reactions to aspartame. But even these individuals are susceptible to the long-term damage caused by excitatory amino acids, phenylalanine, methanol, and DKP. A *few* of the many disorders that are of particular concern to me include the following. Birth Defects ------------- Dr. Diana Dow Edwards, a researcher was funded by Monsanto to study possible birth defects caused by the ingestion of aspartame. After preliminary data showed damaging information about aspartame, funding for the study was cut off. A Gentetic Pediatrician at Emory University has testified that aspartame is causing birth defects. [7] In the book, "While Waiting: A Prenatal Guidebook" by George R. Verrilli, M.D. and Anne Marie Mueser, it is stated that aspartame is suspected of causing brain damage in sensitive individuals. A fetus may be at risk for these effects...some researchers have suggested that high doses of aspartame may be associated with problems ranging from dizziness and subtle brain changes to mental retardation." Cancer (Brain Cancer) --------------------- In 1981, Satya Dubey, an FDA statistician, stated that the brain tumor data on aspartame was so "worrisome" that he could not recommend approval of NutraSweet.
[14] In a two-year study conducted by the manufacturer of aspartame, twelve of the 320 rates fed a normal diet and aspartame developed brain tumors while none of the control rats had tumors. Five of the 12 tumors were in rats given a low dose of aspartame.
[15] The approval of aspartame was a violation of the Delaney Amendment which was supposed to prevent cancer-causing substances such as Methanol (formaldehye) and DKP from entering our food supply. The late Dr. Adrian Gross, an FDA toxicologist, testified before the U.S. Congress that aspartame was capable of producing brain tumors. This made it illegal for the FDA to set an allowable daily intake at any level. He stated in his testimony that Searle's studies were "to a large extent unreliable" and that "at least one of those studies has established beyond any reasonable doubt that aspartame is capable of inducing brain tumors in experimental animals...." He concluded his testimony by asking, "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? .... And if the FDA itself elects to violate the law, who is left to protect the health of the public?"
[16] In the mid-1970s it was discovered that the manufacturer of aspartame falsified studies in several ways. One of the techniques used was to cut tumors out of test animals and put them back in the study. Another technique used to falsify the studies was to list animals that had actually died as surviving the study. Thus, the data on brain tumors was likely worse than discussed above. In addition, a former employee of the manufacturer of aspartame, Raymond Schroeder told the FDA on July 13, 1977 that the particles of DKP were so large that the rats could dicriminate between the DKP and their normal diet.
