He supports many of his arguments weakly and/or anecdotally, so I'm left somewhat unconvinced. However, he freely acknowledges this, adopting the mantra that because his ideas seem like they might work, and because they can't hurt, we may as well try them while we wait for sound evidence (e.g. "Still, I am convinced there is no need to wait for such large-scale results before beginning to include anticancer food in one's diet. It is clearly established that the type of diet I have adopted myself and recommend here does not expose those who follow it to any risks and leads, rather, to health benefits that go far beyond its effect on cancer.")

Personally, I do choose to incorporate a lot of his suggestions for precisely this reason, but I was hoping and expecting that this book would have supported these claims with more substantial evidence.
