Has anyone here read the book "Guess What Came to Dinner"? (Gittleman). The author says that many, if not most, cases of "IBS" are caused by chronic intestinal infection with "bad" types of bacteria, parasites (microscopic forms), and/or yeast(Candida). I keep reading about the increase in food-borne illness (not just E. coli), and am concerned about it. Thanks for your feedback.
