How to Increase Bacteroidetes in Your Gut
How to Increase Bacteroidetes in Your Gut
If you’re wondering how to increase Bacteroidetes in your gut, the most practical first step is to feed them the foods they like: dietary fiber, prebiotics, and a wide variety of plant foods. A diverse, fiber-rich diet may help support Bacteroidetes and overall microbiome balance over time.
In short, focus on legumes, whole grains, vegetables, fruits, resistant starch sources, and fermented foods. These choices do not change the gut overnight, but they can help create a gut environment that supports more beneficial microbial diversity.
Quick answer: how to increase Bacteroidetes in your gut
To support Bacteroidetes, build meals around plant diversity, prebiotic fiber, and minimally processed foods. A steady pattern matters more than a single supplement or “detox” approach. Here is a simple 5-step plan:
- Eat more fiber-rich plant foods at most meals.
- Add prebiotic foods such as onions, garlic, leeks, oats, and bananas.
- Include resistant starch sources like cooled potatoes, cooked-and-cooled rice, and green bananas.
- Choose fermented foods if you tolerate them, such as yogurt, kefir, sauerkraut, or kimchi.
- Keep your routine consistent with hydration, movement, and lower intake of highly processed foods.
What are Bacteroidetes?
Bacteroidetes are a major group of bacteria commonly found in the gut microbiome. They help break down complex carbohydrates and fibers that your body cannot digest on its own. In that way, they play an important role in nutrient processing and microbial balance.

Because they thrive in a diet rich in plant-based fibers, Bacteroidetes are often discussed alongside prebiotics, microbiome diversity, and gut health support.
Foods that increase Bacteroidetes (Bacteroides)
The best way to support Bacteroidetes is through foods that feed beneficial gut microbes. The list below focuses on high-fiber, prebiotic, and fermented options that may help support a healthier gut environment.
- Legumes such as beans, lentils, chickpeas, and peas — rich in fermentable fiber that can help feed gut microbes.
- Whole grains like oats, barley, brown rice, and whole wheat — provide complex carbohydrates and fiber for microbial fermentation.
- Resistant starch sources including cooled potatoes, cooled rice, overnight oats, and green bananas — may support short-chain fatty acid production by gut bacteria.
- Diverse vegetables such as broccoli, Brussels sprouts, carrots, artichokes, onions, leeks, and asparagus — add different fiber types and plant compounds.
- Fruits like apples, pears, berries, and bananas — offer fiber and polyphenols that may support microbiome diversity.
- Fermented foods such as yogurt, kefir, sauerkraut, kimchi, and miso — can support microbial diversity as part of a balanced diet.
- Nuts and seeds including chia, flax, almonds, and walnuts — add fiber and healthy fats that fit a gut-friendly eating pattern.
Why it helps: These foods generally support a more diverse microbiome by providing the substrate that many beneficial bacteria use for growth and fermentation.

What feeds Bacteroides?
If you are asking, “What feeds Bacteroides?” the answer is mainly dietary fiber, prebiotics, and plant diversity. Bacteroides are associated with the breakdown of complex carbohydrates, so foods with fermentable fibers are especially relevant.
Good examples include:
- Oats, barley, and other whole grains
- Beans, lentils, and chickpeas
- Onions, garlic, leeks, and asparagus
- Apples, pears, berries, and bananas
- Cooked-and-cooled potatoes or rice
Rather than relying on one “superfood,” a varied plant-forward diet tends to be the most practical way to support Bacteroidetes and broader microbiome health.
How can I increase my gut bacteria fast?
If you are asking how to increase my gut bacteria fast, the safest answer is to focus on changes that can have a relatively quick dietary impact without overpromising results. Some people notice digestive changes within days to weeks after improving fiber intake, hydration, and meal variety, but microbiome changes are individual and gradual.
Fastest realistic habits to try:
- Increase plant diversity across the week.
- Add one extra serving of legumes or whole grains daily.
- Swap refined snacks for fruit, nuts, or vegetables.
- Include a fermented food if it suits your diet and tolerance.
- Reduce highly processed foods and added sugars where possible.
Consistency matters more than intensity. Small, repeated changes are usually more sustainable for gut health than sudden restrictive diets.

If a microbiome test suggests low Bacteroidetes, it is important to interpret the result carefully. Test results can vary by method, timing, diet, and other factors, so a single reading does not automatically mean there is a health problem.
A diet-first approach is usually the most sensible starting point:
- Increase fiber gradually to avoid discomfort.
- Prioritize plant diversity across the week.
- Use prebiotic foods before considering supplements.
- Include fermented foods if tolerated.
- Speak with a qualified healthcare professional if you have symptoms, a medical condition, or questions about test interpretation.
Supplements or probiotics may be discussed in some cases, but they should be chosen carefully and used with professional guidance when needed.
Probiotics and Bacteroidetes
Probiotics are live microorganisms that may support gut health. However, probiotic products do not specifically “replace” Bacteroidetes, and the effects of any supplement depend on the strain, dose, quality, and the person using it.
What are Bacteroidetes probiotics?
People sometimes use the phrase bacteroidetes probiotics or probiotics bacteroidetes to mean products that may support a healthier microbiome environment. It is best to think about these products as supportive rather than corrective.
How to choose a probiotic
If you are considering a probiotic, look for clearly labeled strains, transparent quality testing, and products with a reason for use that fits your situation. A healthcare professional can help you decide whether a probiotic makes sense for you.

Lifestyle changes that may support Bacteroidetes
Food is the main lever, but a few lifestyle habits can also support gut health and microbial diversity:
- Regular movement: Physical activity is associated with a healthier gut microbiome.
- Stress management: Lowering chronic stress may support digestive comfort and overall well-being.
- Sleep consistency: Regular sleep routines can support healthy daily rhythms in the gut.
- Less ultra-processed food: Reducing highly processed foods may help make room for more fiber-rich choices.
Using microbiome tests to track Bacteroidetes
Microbiome tests can offer a snapshot of your gut bacteria, including Bacteroidetes. They can be useful for learning more about your gut profile and for tracking broad trends over time, but they should not be treated as a diagnostic tool on their own.
How InnerBuddies’ Microbiome Test can help
InnerBuddies’ Microbiome Test can help you better understand your gut profile and identify areas to explore with diet and lifestyle changes.
Understanding your unique gut profile
Everyone’s microbiome is different. Your results may help you see whether you need more fiber, more plant variety, or a more consistent routine to support gut health.
Making personalized changes based on test results
Use microbiome insights as a starting point, not a final answer. The most useful changes are usually simple: more plants, more fiber, more variety, and a steady routine.
