Gut Health 101: Foods That Support Your Microbiome
March 02, 2026 · By Dietitian
Fiber-Rich Foods
Fiber feeds beneficial bacteria. Include whole grains, legumes, vegetables, and fruits. Aim for variety—different fibers support different bacteria.
Fermented Foods
Yogurt, kefir, kimchi, sauerkraut, and fermented vegetables introduce beneficial probiotics. Choose options with live cultures and minimal added sugar.
Prebiotic Foods
Prebiotics feed your good bacteria. Garlic, onions, leeks, asparagus, bananas, and oats are good sources. Include them regularly in your meals.
Polyphenol-Rich Foods
Berries, dark chocolate, green tea, and olive oil contain polyphenols that support gut health. Enjoy them as part of a balanced diet.
Limit Processed Foods
Highly processed foods, excess sugar, and artificial additives can harm your microbiome. Focus on whole, minimally processed foods.
