sentences:  Ralph G. Walton, a psychiatrist at Northeastern Ohio Universities College of Medicine, stated in a self-published 1996 analysis of aspartame research that industry-funded studies found no safety concerns while 84 of 92 independent studies did identify safety concerns.This analysis by Walton was submitted to the television show "60 Minutes" and has been extensively discussed on the Internet.An analysis of Walton's claims showed that Walton left out at least 50 peer-reviewed safety studies from his review of the literature and that most of the research he cites as non-industry funded were actually letters to the editors, case reports, review articles or book chapters rather than published studies.
