Not sure if the links will work but I will give it a try.
Interesting article with Aspartame info: http://www.foodandhealing.com/articles/article-aspartame.htm

Seriously, look up Aspartame+research, you will find a multitude of hits.
Lots of good information to be had. Other interesting topics, Sucrolose (Splenda) which although appears to be a lesser evil still not good, confounding research for those interested... high fructose corn syrup (in sooo much of our commercially produced foods).
All of this being the foundation of why sugar (in small amounts) is the best bet. I would rather eat less than subject my body to the chemicals we have had added to so much of our diets since I was very young. The more I read and research the more angry it makes me.
