If you’ve struggled with stubborn digestion issues, unexplained weight gain, or low energy, your gut microbiome may be out of balance. The good news? It’s fixable with the right microbiome meal plan.
This step-by-step 30-day meal plan makes it effortless to fuel your gut with the right foods. Result? Better digestion, natural weight balance, and a stronger immune system.
Core Principles of a Healthy Microbiome Diet

All gut microbiome meal plans focus on (mainly) one thing: to nourish the beneficial bacteria and support what they do best to keep your digestive system healthy. Such diets emphasize the following:
- Diverse fiber-rich foods (such as resistant starch and inulin) from whole grains, legumes, and vegetables
- Fermented staples like yogurt, kefir, kimchi, etc., for probiotics
- Prebiotic foods include bananas, onions, garlic, and asparagus, among others.
- Polyphenol-rich plant foods like berries, green tea, and cocoa
- Avoid highly processed foods, trans fat, added sugars, and artificial sweeteners
- Avoid taking excessive antibiotics (Learn more about their effect on News Medical)
