Dietary fiber (especially the soluble kind) feeds beneficial gut bacteria, which produce short-chain fatty acids that support colon health. Fermented foods — yogurt, kefir, sauerkraut, kimchi — add live cultures. A varied, plant-rich diet supports the most diverse microbiome. Increase fiber gradually and stay hydrated to avoid discomfort as you add more plants.
