The digestive tract contains trillions of microorganisms, including bacteria, viruses, and fungi. Together, these organisms form the gut microbiome, which interacts with food, intestinal cells, and the immune system.
What Does the Microbiome Do?
Gut microorganisms help break down certain components of food that human digestive enzymes cannot fully process. They also produce compounds that interact with the intestinal environment and contribute to normal immune function.
Supporting a Healthy Gut
A diverse, fiber-rich diet can support a diverse gut microbiome. Vegetables, fruits, whole grains, legumes, nuts, and seeds provide different types of dietary fiber.
What About Probiotics?
Probiotics are live microorganisms found in certain foods and supplements. Their effects depend on the specific strain and health condition, so probiotic products should not be treated as universally beneficial.
Gut Health Is More Than One Factor
Digestive symptoms can have many causes, including food intolerances, infections, medications, inflammatory conditions, and functional gastrointestinal disorders.
Persistent abdominal pain, blood in the stool, unexplained weight loss, or ongoing digestive problems should be discussed with a healthcare professional.
