This book was recommended by our doctor and I started reading it. It goes without saying that a lot of experience and research has gone into this book. This gives a lot of useful insight into the human gastrointestinal system, which is necessary to understand how we can stay healthy. Pros: - Very informative - Concise - Breaks a lot of myths about diet and exercise - Not just tells you what's wrong, but also tells you how you can correct your diet and have a better lifestyle.
