There is no magic or universally accepted diet in Crohn’s disease. There is no need to restrict any types of food in patients with Crohn’s disease. Patients should maintain adequate fluid intake, as well as adequate intake of protein and other nutrients. Obviously patients should avoid high fiber if they are experiencing symptoms of bowel obstruction such as postprandial abdominal pain or vomiting or dilated loops on x-ray studies or evidence of thickening of small bowel on scans. Otherwise high fiber is the way to go. Patients should maintain adequate oral intake so that dehydration will not be a problem.
