This book is a little deceptive in its description. It is really just a long brochure. while it does have information it is more like a "summary" of the bigger books and plan. Of course it suggested that I take out lots of the foods I like and advised me to eat foods I can't eat for various reasons. It had information that I already knew (like dairy products cause an increase of mucus production). I'd say that it's value is more that of a "novelty" than a real source of information.
Like the other "Eat Right 4 Your Blood Type" book that I posted, I didn't really read this one either. I have flipped through it and this one looks like a more shortened version explaining what is okay to eat and things like that. It is very small and compact and could easily be carried with you on a daily basis.
