An individual with ulcerative colitis should avoid caffeine, alcohol, spicy foods, dairy products and any other foods that seem to worsen the condition, according to Mayo Clinic. High-fiber and high-fat foods may also need to be avoided.
Since ulcerative colitis changes over time, an individual’s diet may need to change as well, explains WebMD. Recording each food eaten in a food diary can help an individual keep track of specific foods that seem to be problematic or beneficial. Varying preparation techniques may also contribute to different results from the same food.
In general, an individual with ulcerative colitis should eat a well-balanced diet with plenty of fresh produce, whole grains and protein, notes WebMD. Additional foods that may need to be avoided are refined sugar, carbonated drinks, foods with sulfur or sulfate, meat and foods containing sorbitol.
Additional diet practices that can help an individual with ulcerative colitis include drinking plenty of healthy fluids, eating small meals and consulting a dietitian, states Mayo Clinic. Individuals may take vitamin supplements at the direction of a doctor if nutrients are lacking in the diet or are not being absorbed properly. Avoiding stress is also important because it can worsen symptoms or trigger flare-ups. Ways an individual can reduce stress include exercise, breathing exercises, biofeedback and regular relaxation.
