Hi Jessicah, here is what I know about the autoimmune diet. There are several books which describe variants of it. The eating style is based on the paleolithic diet, which is basically eating foods developed before agriculture. A year ago, I found a complementary practice with a doctor who specialized in nutritional medicine. The basis of the diet is meats, fruits and vegetables. The theory is that the body is “stressed” by digesting certain foods. People who practice this type of diet avoid simple carbohydrates (sugars) and complex proteins (plant proteins, as well as dairy proteins). Books that can help you understand the theory are “Breaking the Vicious Cycle” by Elaine Gottschall, and “The Anti Inflammation Diet and Recipe Book” by Jessica Black. The South Beach Diet is a very close approximation to this concept, and easy to follow. Basically, stay away from anything premade (hope you enjoy cooking from scratch). After struggling to recover for 18 months from a “mild case”, my recovery in the last year has been amazing. I will never go back to my old way of eating. Good Luck!
