Query: Very good diet book with lots of resources available

I have read this book and have given it as a gift at least 5 times. I have learned a great deal about myself and how I respond to different food and often refer to it as resource guide. I am an A blood type and my husband is an O - it has been interesting to find food combinations that are good for both of us and help us both to manage our weight. I think the most valuable take away from this book are cues you can recognize from your body as you respond to different things you eat. As a scientist, the added scientific/medical detail provided added appeal as well as value as a reference resource.
