I don't know how much you know about all the fraud involving aspartame, the reason FDA asked for an indictment against G. D. Searle, but I'm giving you some information of the goings on from Mission Possible Holland: http://www.aspartaam.nl/ artikelen_eng/histfaq.php You will note it says the list of pivotal studies were protected. Later it was released. Barbara Alexander Mullarkey, a columnist for the Wednesday Journal of Oak Park, Illinois, and author of Bittersweet Aspartame: A Diet Delusion , wrote the FDA for a list of the pivotal studies that approved aspartame. A letter from Dr. Rudolph Harris of the FDA [10] included SC 18862, a 52 Week Oral Toxicity Study in the Infant Monkey . Seven were fed aspartame, five had grand mal seizures, and one died. The FDA report of 92 symptoms lists four types of seizures.
