Query: Opinions not Cures

I was very diappointed with this book. It was more the Authors opinion. Throughout the book he referenced his website(that cost addditional money to get the information) as well as his bashing the FDA and medical Doctors. Basically, he shares to eliminate toxins and eat pure to stay healthy. He doesn't offer any cures back by any studies and never refrences any studies. One thing he does refrernce is he had a "severe Mitral Valve Prolapse" he refers to as being a severe heart problem. 1 in a 100 people have this condition. I'm one of them. It is common and treated very easily. I think he is a man out to make money on something he knows little about. I would not buy this book.
