Fiber and Inflammatory Bowel Diseases (Ulcerative Colitis and Crohn’s Disease)

Inflammatory bowel disease (IBD) refers to that group of conditions in which inflammation involves the small or large intestine or both. In common usage, IBD is restricted to those conditions whose etiology is unknown and generally includes Crohn’s disease (CD) and ulcerative colitis (UC). As with many other intestinal conditions of undetermined or uncertain etiology, dietary factors, including fiber, have been proposed to play an important role in pathogenesis.
