Here are some references for the aspartame controversy

References from Humphries 2007 edit

This paper might not be WP:RS because the author relies so heavily on non-WP:RS sources, repeating incorrect information (that DKP is a derivative of methanol, for example) and distorts the sense of some WP:RS sources. At first, I thought the paper was a carefully constructed fabric of hypotheses suggested for further testing, and figured I was having trouble following it because I am not an expert in the field. But now I wonder if the arguments have some internal inconsistancies and just don't make as much sense I would have though they ought to make. I wish an expert would review this review.
