Digestive or gut health refers to how well the gastrointestinal tract functions, including the stomach, small and large intestines, and related organs such as the liver, pancreas, and gallbladder. It also includes the balance and diversity of the gut microbiota—the community of microorganisms in the digestive system—and the gut’s connections with other parts of the body, including the immune system and brain. Because digestion breaks down food and absorbs nutrients, it plays an important role in overall well-being. Nutrition and health are closely linked, and eating patterns can support the body’s needs and influence the risk or management of chronic conditions, including heart disease and type 2 diabetes. Because many factors shape health, personalized, sustainable nutrition choices—alongside appropriate medical care—can support digestive and overall wellness.
