Aspartame - is that a vegetable?

This is a link to a good Q. and A. column in the Globe and Mail focussed on answering the public's health questions. The answer to the question "Is Aspartame Harmful?" is measured. One the one hand, two researchers with ties to the artificial sweetener industry have recently published studies saying there's nothing wrong with it. On the other, a doctor's recent study (he has no ties to the sweetener industry) did find links between aspartame consumption and neurological disorders.

Common sense should make us naturally skeptical of consuming items that are not foods we'd consume in the wild; for example: sugar and other sweeteners, salt, alcohol, manufactured fats like margarine, drugs, or tobacco. Yet because we like, even crave, these non-foods, we keep finding ways to rationalise that they are, in fact, safe. It's very important to be curious and cautious about consuming non-foods and to continue to study them, while acknowledging that food studies are very hard to quantify. Subjects are not locked in rooms for months on end and fed a strict diet, and most of the facts gleaned from these studies come from the subjects self-reporting most of what they ate and drank throughout the study period.

Roll the dice if you like, but I'm not gambling on my health or my that of my family. We are given only one body for our entire lifetime and I'd like to keep mine in optimal condition, by avoiding potential impurities as much as possible.
