Dangers of Aspartame

In 1965, a researcher at G.D. Searle pharmaceutical company inadvertently discovered the artificial sweetener aspartame while working on an anti-ulcer medication. It was discovered that the sweetener was about 150X sweeter than an equal amount of sugar. Over the next decade, the research staff at the G.D. Searle Company conducted a series of studies in an effort to get the product approved by the FDA.

Over all this consisted of about 11 different studies. In 1974 aspartame was approved for use only in dry foods. Its approval was based on these studies. Yet, even before these studies were being presented to the FDA, the pharmaceutical giant was under investigation for improprieties associated with several of its other drugs.

During this investigation, Dr. Adrian Gross was place in charge of examining these studies and Jerome Bressler was assigned to examine three of the studies. This investigation included a through examination of the pathology laboratory used in the tests, interviews with the scientists and technicians involved and a careful analytic review of the studies themselves.

In a letter to Senator Howard Metzenbaum, Dr. Gross discussed many of their findings in this investigation. He pointed out that at the heart of the regulatory process was the ability of the FDA to "rely upon the integrity of the basic safety data submitted" to the FDA. Further, he says, "Our investigation clearly demonstrates that, in the case of G.D. Searle Company, we have no basis for such reliance now."
He then pinpoints why he had reached this conclusion, when he states:

"Through our efforts, we have uncovered serious deficiencies in Searle's operations and practices which undermine the basis for reliance on Searle's integrity in conducting high quality animal research to accurately determine or characterize the toxic potential of its products."

Dr. Gross expressed his disdain at the way teratology experiments were conducted. These are critical tests with any new drug because it determines possible dangers to unborn children when their mothers are exposed to the product during pregnancy. He found that technicians responsible for the tests had no formal training in teratology or toxicology. In fact, they were given some books by the company and trained themselves for 3 months.

Of most concern was the way the carcinogenicity tests were conducted. These are tests to see if the product could cause cancer. According to the law, any product intended as a food product cannot have demonstrated cancer-causing ability at a dose 100X that commonly consumed.

Even though the tests were poorly conducted they did demonstrate that aspartame was associated with a dramatic, dose-dependent, increase in a variety of brain tumors-mainly astrocytomas-the type commonly seen in humans. This means that the higher the dose of aspartame the more tumors that were found.

The most appalling findings were by Dr. Bressler's investigation group. They found that in several instances malignant tumors were classified as benign and that in others, tumors were removed from rats and tissue slides and reported as normal.

Dr. John Olney, a neuropathologist and neuroscientist, pointed out to FDA investigators that aspartame contained at least two distinct components that could harm the brain-diketopiperizine and aspartic acid. The former is a suspected carcinogen and the latter an excitatory amino acid. As a world expert on excitotoxicity, a process where amino acids such as aspartic acid and glutamic acid causes brain cells to be excited to death, he understood the real danger to babies and small children. His laboratory studies had demonstrated that high dose aspartame could cause the very same brain injury as other excitotoxins.
