This book is better out of the 2 acid book I read, as this diet isn't as restrictive as the other book. It provides a logical diet to start with and then continue on, if you want to change your lifestyle. I've heard many good things about this diet, from people with artritic pain (like me) so I thought I'd give it a go! I only followed this diet for a few days, but my skin got a lots clearer, and I didn't get sugar highs and lows all day, so hopefully in the long term my back pain will be helped a bit! If I can last on this diet! No meat, dairy, processed food, coffee.. or even worse... alcohol!
