The recommended diet for people with chronic ulcerative colitis includes plenty of protein, whole grains and good fats, according to MedicineNet. Some examples of such foods are fish, meat, breads, fruits and vegetables. It is often helpful to avoid caffeine, high-fiber foods, alcohol and refined sugar.
Maintaining a proper diet is one of the most effective methods of treating ulcerative colitis. If a patient does not receive proper nutrition, he can experience dehydration, gastrointestinal problems or anemia. Some patients need dietary supplements such as vitamin B12 to avoid nutritional deficiency, claims MedicineNet. Keeping a food diary can be a helpful way to associate dietary triggers with ulcerative colitis symptoms.
