There are literally trillions of bacteria in the gut and changes in the balance of your gut bacteria have been linked to many physiological and psychological health conditions. The health benefits of probiotics and prebiotics are only now just being realized. Probiotics contain live bacteria that can seed the growth of a good bacterial colony in the gut. For probiotics to work, there must be a plentiful supply of food for the good bacteria to feed on. Prebiotics are foods that contain special fibers that good bacteria digest and ferment. If you want to improve your gut and experience the health benefits of prebiotics and probiotics, you should add them both to your diet. A healthy life begins with a healthy gut!
