The first thing which impressed me in this book is that everything that I love eating was included in my blood type, except...bread. I was trying to understand a small health problem that I had, and this book showed me what it is: wheat intolerance! When I stopped eating whatever contained wheat my problem was solved. You can really improve your health condition and your immune system by learning what is blood type friendly and what you should avoid. As mentioned in the book, many people suffer from intolerance to a particular food but they don't know it because it could be something they eat daily, like in my case wheat, bread. As a result you always have a problem and you can't find what causes it. It has a full range of recipes which you can follow, combinations of foods, in order to prepare your meals easily, it shows you how to arrange your kitchen and your shopping blood type friendly. Excellent book
