Bacteroidetes Food Guide: 7 Gut-Boosting Foods to Nourish Your Microbiome

If you’re aiming to optimize a bacteroidetes food profile, focusing on fiber-rich, diverse plants can make a noticeable difference for your gut. Science supports that Bacteroidetes thrive on complex carbohydrates and resistant starch, so the seven gut-boosting foods below are practical, tasty ways to nourish your microbiome and support this important bacterial group. Pair these choices with a data-driven approach to gut health to see how your diet measures up on real-world metrics. Seven gut-boosting foods to nourish your microbiome include: lentils and other legumes; oats or barley and other whole grains; apples and pears with their pectin; onions, garlic, and leeks for prebiotic inulin; leafy greens and cruciferous vegetables like broccoli and cabbage; berries such as blueberries and raspberries; and fermented foods like sauerkraut or kimchi that add microbial variety while delivering fiber. Each of these foods supports a bacteroidetes food ecosystem by boosting dietary fiber, which fuels beneficial metabolic activity. If you’re unsure how these fit your unique gut, you can explore personalized guidance that accounts for your diet and stool data, rather than relying on one-size-fits-all advice. That’s where InnerBuddies comes in. As a white-label Gut Health Operating System, InnerBuddies powers partner programs and consumer products with a comprehensive suite of microbiome tools. The platform includes a Gut Microbiome Health Index—a score from 0 to 100 built on an exclusive collaboration with EAFIT University in Colombia—to quantify overall gut health. It also tracks Bacteria abundances for a top 40 panel and maps Bacteria functions, labeling each metabolic pathway as positive or negative so you can see how your results compare to a healthy cohort. With Target Group analysis—from Healthy Aging to sports-focused profiles like Endurance and Power Sport—you get deep dives into the pathways that matter for you, plus personalized nutrition and probiotic/prebiotic recommendations tailored to your unique gut microbiome. InnerBuddies also makes it easy to translate insights into action. By integrating 3-day food diaries with stool samples, the system builds practical, individualized nutrition advice that helps you choose bacteroidetes food options that align with your goals. And because InnerBuddies offers both consumer and B2B solutions, you can access the same advanced tools whether you’re shopping for yourself or building a gut health program for customers.
