Hi all :) I haven't read the book yet, but I've heard descriptions of the basic idea behind the diet-by-blood-type methodology, and it seems harmless enough. As I see it, the ideas outlined in the book could be a very good starting point for people beginning a journey of discovering what is the best diet for them or a nudge for those who may have gotten themselves into a rut, but no diet out of a book is the be-all and the end-all. Even within blood type groups, there are individual variations and sensitivities in other systems of the body which such seekers will still need to ferret out for themselves. What do you folks think?
