I would also like to point out the conclusion in the article you linked:
> These 3 studies add to a growing body of evidence on the adverse health effects of soft drinks; however, given the limited and conflicting data available, these findings can at the present time be considered only suggestive, not conclusive, but they warrant further investigation in other prospective studies with data on long-term intake of soft drinks, diet soft drinks, and aspartame
Take that along with the extensive references in the Wikipedia article and you can see why I say the public is asking the food industry to prove a negative. The closest they can come is, "something that contains aspartame seems to be a bit unhealthy, but not always, but sometimes," yet those same people (like you) will say that aspartame itself is the issue. It's just silly.
