Common IBS Trigger Foods

Foods High in Insoluble Fiber

Some people are sensitive to foods that are very high in insoluble fiber, specifically wheat bran, high-fiber breakfast cereals, specially formulated high-fiber breads, and whole wheat pasta. Other people are extremely sensitive and react to foods with moderate amounts of insoluble fiber, such as whole grain breads and crackers, wheat germ, popcorn, bulgur, quinoa, millet, amaranth, and whole nuts and seeds.
