Cut out any of your usual triggers. You may want to avoid beans, whole-grain or multigrain breads, fruits, vegetables like cabbage or broccoli, and fatty or fried foods. Peel vegetables and fruits before you eat them; it may help. In addition to safe foods like bananas, rice, applesauce, and toast, you need protein, too, like chicken, ground beef, or tofu. It will keep your strength up and help you heal. Alcohol, caffeinated drinks, and juices may upset your stomach.
