For anyone else reading this, feel free to ignore this person's post. If there's a good case to be made that aspartame is harmful, this isn't it. Few of these studies are germane to typical human exposure, and typical exposure levels aren't strongly correlated with large increases in risk.

For the author, try reading some of these papers. Also don't bother linking to press releases or newspaper articles, you're just wasting other people's time. You probably want to skip the animal studies too. Go for no more than three links, preferably meta-studies -- at least if your intention is to be taken for something other than a crank.
