Probiotic foods contain live beneficial bacteria that improve gut health (e.g., yogurt, kefir, sauerkraut), while Prebiotic foods are high-fiber, non-digestible carbs that feed those bacteria (e.g., garlic, onions, bananas, oats). Combining both, such as yogurt with bananas, best supports a healthy microbiome

We get our first gut bacteria when we’re born. Breast milk gives babies healthy bacteria. Food helps add more good bacteria to our gut. We also get bacteria from people and places around us. Some gut bacteria have been with humans for a very long time.
