Inflammation, the most common underlying component chronic conditions. It is has ""-itis,"" it is inflammation. If there is pain, there is inflammation. This book is not written for the mainstream population that believes a balanced diet is a PopTart in each hand. HOWEVER: If you are willing to do what it takes to get better, this is a great start. The biggest problem with an anti-inflammatory/elimination diet is knowing how to fix yummy food. There really isn't one book that I have found that addresses all of these restrictions. This book is cost friendly, providing charts of those foods that don't necessarily have to be organic, how to make your own Kefir, Kombucha, Sprouts and Yogurt as well as nut milks and nut butters. It's NOT perfect, likely quite a few typos. Not all of the recipes will be just right, you may have to tweak for your own tastes, ect. But it is a good base and foundation. There is a companion Food Tracking and Stats Journal available for sale. Bon Apetite
