Gut Health Defined by Digestive System Function and Microbiome Role
Gut health is characterized by the normal operation of the digestive system, which encompasses the interconnected organs and processes responsible for food breakdown, nutrient absorption, and waste elimination. This intricate system begins with chewing and saliva, progressing through the stomach and small intestine where digestive enzymes facilitate further breakdown. The small intestine is crucial for nutrient absorption into the bloodstream or lymphatic system. A key component of gut health is the gut microbiome, a diverse community of microorganisms, primarily found in the large intestine. This microbiome interacts with diet, influences nutrient utilization, immune function, metabolism, and the gut-brain connection. Maintaining a varied and balanced diet rich in plant foods and fiber is considered a practical nutritional foundation for supporting digestive wellness and the gut microbiome. Fermented foods, such as yogurt and kefir, can also contribute to a diverse diet, though the types and amounts of li...
