Haven't read it, but it sounds interesting.  I would never go back to a completely vegetarian diet, but I can certainly see the benefits for the average American consumer to reduce meat consumption.  We never have meat as the central focus of our meals.  It is always more of the side or an ingredient in a dish.  That is just the way we like to eat.  I have never really gotten on the raw food bandwagon though, although I have no opinion about how good that may or may not be for a person.  As far as the meat thing though, I think humans are designed to be omnivores.  I did a lot of reading about that when I worked in a natural foods store.  I remember reading that only animals that eat a certain amount of meat have incisors I believe it was (don't quote me on that though, LOL).  Our teeth are not like those of animals that are strictly carnivorous, nor like those that eat only plants.
