Roberts, author of Aspartame Disease: An Ignored Epidemic, who describes his patients' adverse reactions to it; firefighter Janet Starr Hull, who wrote Sweet Poison: How the World's Most Popular Artificial Sweetener Is Killing Us—My Story chronicling her near death experience due to aspartame toxicity and her subsequent fight with drug companies to get it off the market; and even himself, who in his famous eponymous diet eschews the stuff.
