Yes I have read it, just in the last few days actually, I have been researching around the subject for about a year and it is the most informative book on dealing with inflammatory and autoimmune conditions I have found. It's a restrictive protocol though,it is based on The Specific Carbohydrate Diet, which was outlined in Breaking The Vicious Cycle which has been used since the 50's at least. Definitley worth your time, I would read Paleolithic Solutions too but I would put reading GAPS and removing grains and dairy at the top of the list.
