" Aspartame, used in most diet drinks, is sold as NutraSweet and Equal.Through the years, it has been blamed for a host of conditions, including brain tumors, seizures, birth defects, multiple sclerosis and lupus, though there's no evidence to back up these claims. Some people also report side effects such as headaches, dizziness and indigestion, but no one knows how widespread they are. The only proven risk is to the small number of people with conditions, such as advanced liver disease, that cause problems metabolizing phenylalanine, an amino acid in aspartame. They are the targets of required warning labels."
