Begin by adding resistant starch to your meals. Cooked-and-cooled potatoes, green bananas or parboiled rice deliver starch that resists digestion in the small intestine and reaches the colon intact. There, it feeds beneficial bacteria and helps produce short-chain fatty acids that reinforce the intestinal barrier and calm inflammation. Next, explore polyphenol-rich plants. Berries, dark chocolate (70% cacao or higher), green tea and colorful spices such as cinnamon and cloves provide antioxidants. Gut microbes thrive on these compounds, converting them into metabolites that support heart health, insulin sensitivity and balanced bacterial populations. Don’t overlook hydration and chewing.
