This is a book of rabid propaganda to scare people into eating raw, and buying over priced items at the authors' web based business.
If, you are interested in raw foodism, and want a workable set of books that can give you an introduction, and road map into the world of raw foodism, please read Norman Walker's series of books on the subject. They are, while not backed up by "hard science", very good at helping the reader along this path.
This book is opinion based, scientifically lacking. In fact, I believe someday, science will prove the validity of the raw food diet. But it won't happen by the evidence presented in this book.
