This chapter examines the gastrointestinal benefits associated with some therapeutic dietary approaches and specific functional foods for digestive health. Elimination diets, including the FODMAP diet, specific carbohydrate diet, 6-food elimination diet, and elemental diets, have all shown specific therapeutic benefit. Each of the various phytochemicals and zoochemicals (protective components from animals) has its unique physiological benefits. They are probiotics, prebiotics, fiber, omega-3 fatty acids and phospholipids, and bioactive peptides. This chapter will review each of these food bioactives in detail, listing the richest food sources and highlighting the effects these foods have on the health of the GI system. The chapter also describes how each bioactive food component supports and maintains the structure and function of the GI system, and provides an overview of how each nutrient targets the pathophysiology of GI disorders and disease. Therapeutic elimination diets, medical foods in GI health, and special dietary considerations are also outlined.
