What Are Prebiotics And How Do they Affect Diets?

Everyone's talking about probiotics these days, but what about prebiotics? Prebiotics are nondigestible carbohydrates that feed the good bacteria in your gut. Prebiotics help probiotics flourish and studies have found that prebiotics reduce the risk of colorectal cancer and could improve bone density. Prebiotics are found in lots of foods, some of which you're probably already eating on a regular basis. They can be found in raw asparagus, bananas, garlic, and onions.
