Wheat Belly Review by Julie Jones
Goes through every claim made in the book. A definite must-read before you buy!

Gives great, detailed explanations of studies and principles used throughout the book. Even if you just want to learn how to look at claims critically and don't care much about the book itself, this is a great read.
