Well I have known this for a long time. Just take good look at Aspartame but in the past Donald Rumpsfield got Aspartame out on the market. Your even better off eating regular sugar by the handfuls than having aspartame in your system. And just think it is in most gum that kids chew. But you don't hear about Aspartame being banned even though kids eat tons of it and can make them obese and sick and even cause diabetes. Where is the FDA on that?
A good solution to Aspartame is adding Stevia to these diet drinks instead of Aspartame or don't drink soda at all. I know some companies are going to Stevia instead. If something is made in a lab like Aspartame its best not to trust it.
