The Specific Carbohydrate Diet is a nutritional regimen used to treat a variety of chronic and auto-immune disorders including Crohn's Disease, Celiac Sprue, Ulcerative Colitis, Diverticulitis, Celiac Disease, Autism and Cystic Fibrosis. Commonly compared to the Atkins Diet and other low-carbohydrate approaches, the SCD eliminates all starches, processed sugars, and complex carbohydrates. Popularized by Elaine Gottschall's book Breaking the Vicious Cycle, the diet is specifically designed to alleviate signs and symptoms of many of these chronic conditions. However, Gottschall makes it clear that if one is thinking about following the diet, one must do so with what she calls "fanatical adherence," meaning that it should be followed to the letter for best results.
