Your gut is home to a vibrant ecosystem of 38 trillion organisms, known as the microbiome. Think of it as a “zoo” in your bowel, filled with bacteria, yeast, and other tiny organisms that influence everything from digestion to mood. The key to gut health lies in nourishing the right bacteria with a diverse, fiber-rich diet. By incorporating more plants, practicing good hand hygiene, and making gradual dietary changes, you can create a thriving microbiome that supports digestion, immunity, and even mental well-being.
