Gut health has become a hot topic, with shelves stocked full of kombucha, probiotic snacks, and prebiotic sodas promising digestive and stronger immunity. But what does science actually say about these trends, and how can people support their gut naturally?
The gut typically refers to the stomach and intestines, which host trillions of helpful bacteria that digest food, support immunity, and even influence mood. Probiotics are live beneficial bacteria found in foods like yogurt, kefir, kimchi, and sauerkraut, while prebiotics are types of fiber that feed those bacteria. The best way to support your gut is to focus on a balanced, fiber-rich diet, adequate hydration, and limit highly processed foods. It’s important to include both soluble fiber, found in oats, beans, and fruits, and insoluble fiber, found in whole grains, nuts, and vegetables. Soluble fiber helps feed gut bacteria and regulate digestion, while insoluble fiber supports regular bowel movements.
But what about all of the products claiming to support gut health? While some of these products may have some benefits, the evidence is very limited. Probiotic beverages may contain live bacteria, but the strains and quantities are often insufficient to produce meaningful effects. Prebiotic beverages usually don’t contain a significant amount of fiber.
Many of these products are also high in sugar, which can counteract gut health benefits. Research shows that excess sugar can encourage the growth of bacteria linked to inflammation, while reducing the types that help protect the gut lining and keep the immune system in balance. Powdered greens supplements can be helpful for those who struggle to eat enough fruits and vegetables; however, they aren’t more effective than simply eating whole foods.
While probiotic drinks and snacks can be enjoyable and potentially helpful, the foundation of gut health comes from everyday dietary choices rather than trendy products.
