I have been gradually transitioning to a raw-foods diet (I have been vegetarian for a little over two years), so I have been reading a ton of books on the subject. It's a good thing that this was not the first one I read. It's a shame that the authors, while being highly motivated and passionate about a raw-food diet, have chosen to advocate the subject in such an in-your-face, absolutist manner. It's really a turn-off. They have taken stances that are easily supported by documented facts, but instead of supporting them with facts, they choose to make raw-foodism sound like a religion. It's not a religion, it's just a way of eating. I'm sure their approach is a turn-on for some people, so perhaps it's good that a book like this exists for those people who need to hear the message this way.
That said, I'd avoid this book until you've read some more sane and well documented books like Dr. Norman Walker's "Enzyme Nutrition," which is the most scientific and documented of all the literature on the subject. Other good books are Ann Wigmore's wheatgrass book and some of her other books; any of the books by Steve Myerowitz; and the "How I Conquered Cancer Naturally" book. I have also heard that two books called "The Raw Life" and "Blatant Raw-Foodist Propaganda" are good. The Natural Hygiene literature is generally very good as well. Take advantage of all the raw food related web sites out there.
Sorry to diverge from the review, but after getting off coffee, soda, aspartame, refined sugar, and other obvious evils, I have been increasing the raw food in my diet gradually to the point where my diet is 80-95% raw most days. The results have been incredible. I feel amazing (everyone always says that, but it's true) and the pounds are just falling off. I don't feel deprived at all, and eating takes on a new meaning when you can feel the food nourishing your body in a way that cooked food never did. You owe it to yourself to try this, especially if you are infirm or overweight in any way. Take it one step at a time. No need to switch 100% your first day.
