A potential game changer of a study was done at Seattle Children's Hospital and published in the Journal of Clinical Gastroenterology in December of 2016. The study tested the Specific Carbohydrate Diet (SCD Diet) in pediatric patients with crohn's disease and/or ulcerative colitis. With nothing other than dietary changes, at the end of the 12 week study, 8 of the 10 participants were apparently in clinical remission. The diet also had a significantly positive impact on microbial balance in the stool (it reduced harmful bacteria). The SCD Diet is quite restrictive in that it does not allow most starches, sugars, and dairy (some exceptions), but it does allow things like most meats, eggs, vegetables, fruits, home made yogurt, and honey. If you have intestinal bowel disease, consider discussing this diet with your Doctor.
