Prebiotics are nondigestible substances like dietary insoluble fibers etc. that act as food for the gut microbiota. Essentially, prebiotics stimulate growth or activity of certain healthy bacteria that live in your body.They act like fertilizers that stimulate the growth of healthy bacteria in the gut.
Prebiotics are found in many fruits and vegetables, especially those that contain complex carbohydrates, such as fiber and resistant starch. These carbs aren't digestible by your body, so they pass through the digestive system to become food for the bacteria and other microbes.
Benefits of prebiotics
One of the biggest advantages of prebiotic supplements is that they are highly stable, being unaffected either by temperature or long-term storage.
Prebiotics are also resistant to the body's enzymes and gastric acids, which means that they are not destroyed, digested, or absorbed as they travel through your digestive system unlike many probiotics. Prebiotics reach the colon intact and unaltered.
Consequently, they can be added to almost every type of food, drink, or supplement without compromising their effectiveness.
