Q: Although Jax presents the gluten free lifestyle with a great attitude, anyone serious about the diet knows that it isn't this easy. The hard info that Jax gives in this book is outright wrong and could be very dangerous to some one new to the diet. She needs to loose the casual approach and get real about being truly gluten free.
A:
Negative
