Dietary habits that contribute to a healthy gut microbiome include consuming diverse, fiber-rich foods. Foods high in prebiotics, like whole grains, fruits, and vegetables, encourage the growth of beneficial gut bacteria. Probiotics from fermented foods such as yogurt, kimchi, and sauerkraut also play a crucial role in promoting a balanced microbiome. Avoiding excessive sugar and processed foods further supports gut health. A well-rounded diet not only nourishes gut bacteria but also strengthens the immune system and enhances digestive function, leading to overall well-being.
