The Gut-Friendly Shopping List

These foods are backed by research for microbiome support:

• Legumes (lentils, beans, chickpeas) — among the richest sources of prebiotic fiber, producing abundant SCFAs
• Alliums (garlic, onions, leeks) — contain inulin, a prebiotic that specifically feeds Bifidobacteria
• Whole grains (oats, barley, rye) — their beta-glucan fiber nourishes diverse bacterial populations
• Fermented foods (yogurt, kefir, kimchi, sauerkraut) — deliver live bacteria plus the substrates they feed on.
