If you have inflammatory bowel disease (IBD), avoid fried foods and refined carbohydrates, because they prompt your body to produce inflammatory chemicals that can stimulate an allergic response. Avoid dairy products, spicy foods, and fats all of which might aggravate your colon and make your symptoms worse. Try keeping a food/symptom diary to see what foods make you feel better or worse, and adjust your diet accordingly. Cruciferous (cabbage family) vegetables, like cauliflower and broccoli, may make you gassy. Watch out for nuts, seeds, and popcorn, all foods that might irritate your gut.
Eat foods rich in healthy omega-3 fats, such as fish; low-fat proteins, such as chicken with the skin removed or tofu; check with your doctor or nutritionist about eating foods high in soluble fiber, such as oatmeal.
