If you know absolutely nothing about health and don't like a lot of jargon, this book is for you. Diaz takes complicated scientific concepts and explains it very clearly and directly. She also spins it in a very positive way leaving you feeling lighter and happier, like that positive friend you keep around because she always makes you feel better.

If you do have some knowledge about nutrition and health, this might not be for you. It will feel a lot like she's dumbing it down. This is very basic stuff, even if it is presented in such a positive way. If you want in-depth knowledge this is not the book for you.

If you want something that makes you feel better about making healthier choices instead of feeling like you're doing everything wrong, I recommend giving "The Body Book" a shot.
