Dr. Gross, and his massive, thorough report detailing the growth of brain tumors in laboratory rats. This is one of the most thorough and damning documents that exist. If someone is trying to blind you with science, tell them to read this thing, and to comment on it. If they can't, and they still think they are so smart, you know that they are blowing smoke up your you-know-what! http://www.dorway.com/gross.txt

These are Dr. Gross's credentials, by the way - he was the FDA's toxicologist, and he tried to stop them from giving blanket approval to aspartame:

That is how he signed his letter to Senator Howard Metzenbaum, who also tried to stop aspartame from poising us, and this is the text of Dr. Gross's letter, at the following URL. The original letter is, of course, on FDA letterhead stationary and it is a valuable document indeed - http://www.dorway.com/gross3.html

Dr. Roberts's report on brain cancer and brain tumors has 32 separate references - all scientific studies or reports alluding to research and statistical information - http://www.dorway.com/betty/brainc.txt

Dr. Olney on brain tumors. Beginning in the 1970's, before aspartame was ever approved, it was already known that it would cause brain tumors - http://www.dorway.com/betty/allolney.txt

Russell L Blaylock M D, and his report on excitotoxins - mentions brain tumors, along with Lou Gerhig's disease (ALS), and a lot of other brain disorders - http://www.dorway.com/blayart1.txt
