Prebiotics and probiotics are both beneficial to our health, but they are different in many ways. Prebiotics are a type of dietary fiber that feeds the beneficial bacteria in our gut, while probiotics are living microorganisms that provide health benefits when consumed. Prebiotics are found naturally in certain foods, while probiotics must be consumed in supplement form or through fermented foods like yogurt and kefir. Prebiotics are not broken down in the digestive system, so they pass through the body undigested and help feed beneficial bacteria. Probiotics, on the other hand, are broken down in the digestive system and may provide health benefits such as improved digestion and improved immune system function.
