People with inflammatory bowel disease, or IBD, often say that specific foods make their symptoms better or worse, but there is no good scientific evidence to support a specific diet. In this study, nearly 7,000 patients with Crohn's disease or ulcerative completed a survey about the their diet and IBD symptoms. Yogurt and rice were most often reported to improve symptoms. Vegetables, fruit, spicy foods, fried foods, milk, red meat, soda, popcorn, dairy, alcohol, high fiber foods, fatty foods, seeds, coffee and beans were most frequently reported to worsen symptoms. In general, patients with ulcerative colitis ate more fruit, vegetables, beans and popcorn than patients with Crohn's disease. Crohn's disease patients with an ostomy tended to eat more cheese, sweetened beverages, milk, pizza and processed meats than Crohn's disease without an ostomy.
