I read about how diet soda is so bad for you but none of these articles cite any real studies showing the negative side effects. Most of these studies state that you body turns the "Aspartame" into formaldehyde and also into acetone and how bad this is for you. Well, your body produces these in a number of different processes and in such small quantities that it causes no harm. Now I'm not saying that you should drink acetone or formaldehyde, but the quantities you produce from "Aspartame" doesn't seem to be enough to matter. Can anyone show me a real study with evidence to back up the diet soda being "bad".
