What’s the Difference Between a Prebiotic and a Probiotic?

Probiotics and prebiotics serve very different functions within the body, and prebiotics are actually necessary for probiotics to flourish. But let’s back up a little. Probiotics are known as the good kind of bacteria that live in the gut and are instrumental in the function of digestion. The probiotics in your body work to break down fiber and make it easily digestible to keep things running smoothly. Probiotics can be found in foods like yogurt and sauerkraut or attained through taking probiotic supplements, which experts agree is generally safe to do so for most people. 

Prebiotics, on the other hand, are nondigestible plant fibers that help feed the probiotics in your body. They are a type of fiber and come from heavy-fiber foods, such as whole grains, fruits, and vegetables, and, of course, supplements. When they feed the healthy bacteria in your body, your body can function as it should. Your digestion will work properly and the immune system will be at its peak to help fight off any potential infections. 

Foods that are high in sugar and fat feed the nonhealthy bacteria in your body, which can result in inflammation and digestive discomfort. The best way to make sure your body is functioning as it should? Eat a healthy diet rich in fruits, vegetables, whole grains, healthy fats (such as avocado), and lean protein. 

If you’re concerned that you’re not getting enough pre- and probiotics in your diet, you might want to consider supplements. Although these are safe for most people, it’s always a good idea to chat with your doctor, who can understand if your body will have any negative side effects to the supplements.
