I've heard alot about the artificial sweetener used in thousands of products "Aspartame" has been said to cause cancers, brain lesions, lowering I.Q., as well as quite a slew of other serious health problems. I've been drinking diet soda for quite a few years now, I don't know if I am greatly increasing my chances of developing certain cancers in my future. I switched from regular soda to diet soda in hopes that I would lose weight, which I did. Another toxin in cola products is the chemical "Benzene", which is well known to damage cells and cause cancer. Is Aspartame really as dangerous as some people claim it is?
