you are focusing on one individual....did you see Rumsfeld's comments on youtube? Your argument is the same as focusing on Billy Meier as proof that the entire UFO phenomenon is bogus. There are an abundance of natural health professionals including MDs who are against aspartame. The fact that "general medical professionals" dismiss any of these claims doesn't surprise me. They also tend to dismiss the effectiveness of supplements/herbs/alternative therapies that have been used for decades as "quackery" yet continue to prescribe toxic medicines which are ultimately recalled as public health risks a few years (or even sooner) after their introduction. How many of the medical scientists who proclaim aspartame as safe have personally done any studies in their patients?
It's proven simply that in a can of diet soda left in heat near 100 degrees for a period, the aspartame will chemically break down into formaldehyde and other neurotoxins. This has been done and measured. Well guess what? Our bodies are 98.6 degree ovens....some even hotter when diet beverages are consumed on hot days.
I read in a natural journal some years ago about a guy who worked at a plant that makes aspartame...he got accidently covered with the powder without an enviro suit and later died.
But again- hey....feel free to drink as much as you want:)
