A courageous and straightforward account of fluoride and the politics of fluoridation by one who was in the thick of the scientific and political battles for over a quarter of a century. Yiamouyiannis, a Ph.D. in biochemistry, documents with about 50 pages of references a very readable explanation of how fluoride upsets the body's collagen metabolism, causing damage to bones, teeth, connective tissue, arteries and skin; how it damages DNA and upsets the body's ability to repair its DNA, with tumors and cancer as a result; and how it damages enzymes and proteins, upsets the immune system, and causes autoimmune diseases. He thoroughly refutes the idea that fluoride is beneficial in preventing tooth decay, and that it has a useful function in human nutrition. It is, in fact, a toxic pollutant generated by many industries, such as the manufacturing of aluminum, phosphate fertilizer, steel, nuclear materials and fuels, ceramics, brick, glass, concrete, to name a few. These folks have turned a profit by disposing of this poison in our water supplies. Yiamouyiannis lays out the long, ugly, and outrageous history. He is a lot more even-tempered in his presentation than you will probably be after reading his book. A must-read for anyone contemplating the issue of water fluoridation, and wanting to do so from a factual basis.
