I hope the two previous reviewers know what they are talking about because when I flipped through this book I got really depressed and overwhelmed. I'm a type A, as is my daughter and the book made it sound like I was doomed ... the very blood flowing through my veins was killing me -- I was destined to get cancer. To prevent this, according to the book, I can eat fruits and vegetables but no cheese or any dairy (except things like goats milk) no meat or chicken, only a few types of fish, and no pepper among other things. I should avoid seltzer water, club soda and vinegar, but coffee, soy sauce and wine are beneficial. The whole thing was so overwhelming for me. The last reviewer (assuming his facts were accurate) put it into a better perspective. As far as I can see in the book there's no indication of how much more apt an A type was to get cancer. Reading it, I got the impression that me and others unlucky enough to be born with the flawed type A blood were all going to get cancer and what's more, are much less likely to survive it. Maybe people with better blood types will enjoy this book more.
