Prebiotic Fiber: Fuel for Your Friendly Gut Bacteria
Prebiotic fibers act as a special food source for beneficial bacteria living in your gut. Unlike regular fiber, prebiotics are fermented by these microbes, helping them thrive and support a healthy balance in your digestive system. Naturally found in foods like onions, garlic, bananas, and chicory root, prebiotic fiber is often added to supplements to nurture your body’s own helpful bacteria.
