"Industry conspiracies: Conflicts of interest in the studies performed on
aspartame and the way in which its approval was obtained is an ongoing controversy. Dr. Robert Walton surveyed the studies of aspartame in the peer-reviewed medical literature. He states that of the 166 studies felt to have relevance for questions of human safety, 74 had Nutrasweet industry (those who make aspartame) related funding and 92 were independently funded.
One hundred percent of the research performed by the company who makes aspartame confirmed aspartame's safety, whereas 92% of the independently funded research found problems with consuming aspartame. Other reports of federal employees working for the companies responsible for the testing and distribution of aspartame are cited on all of the sites and books opposing the use of aspartame."
