Diet Soda Contains Aspartame

Aspartame is 180 times sweeter than sugar, and some animal research has linked consumption of high amounts of the sweetener to brain tumors and lymphoma in rodents. The FDA maintains that the sweetener is safe, but reported side effects include dizziness, headaches, diarrhea, memory loss, and mood changes. Bottom line: Diet soda does you no good, and it might just be doing you wrong.
