I read "The Body's Many Cries for Water" by Dr. Batmanghelidj recently. I borrowed it from a library, but you can get a free pdf online at

There's a lot of ranting and complaining about the American Medical Association dismissing his theories. He was an immigrant from Iran who came to the U.S. after being released from prison for his support of the Shah - he treated fellow prisoners with water because medication was not available. Maybe that made him less able to understand why he was being frozen out.
I think sometimes people are ahead of their time, and he may be, but he probably harmed the chances of his theory being accepted by writing many, many letters to the AMA and the NIH and criticizing them for not believing him.
It reminds me of the skepticism about probiotics that has only recently started reversing. I read that the medical acceptance of probiotics was harmed by the fact that there was a booming business being done by alternative health practitioners. In the eyes of the medical establishment, that tainted the concept for a long time and probably kept valid research from being done.
I am glad for the healthy skepticism I read on this forum, combined with open-mindedness and realism about the limits of current knowledge! But we will have to be careful. One good thing, I think, is there's not commercialism and no saleable diet that might brand us as a group of faddists.
