For those who care to read and make up their own mind. Here's the rebuttal by Dr. Campbell, the author of The China Study, to the criticisms of the book. Excerpt:
"My present views on diet and health are based on the consistency of the vast majority of evidence produced by a wide variety of studies. I see three types of evidence that has most influenced my present views. First, there is the research data from our own studies that are summarized in our book. Second, there is the evidence obtained by many other laboratories, a sample of which is summarized in our book. Third, there is, perhaps, the most important evidence of all, the clinical experiences of the practicing physicians who I had come to know, especially those of Drs. John McDougall, Caldwell Esselstyn, Jr., Terry Shintani, Joel Fuhrman and Alan Goldhamer. For me, these medical practitioners, entirely on their own initiative and knowledge, were advising, with impressive success, their patients with the same information that I had come to know from the scientific literature and laboratory. The proof is in the pudding, so to speak. The idea works!"
