Veggies are another extremely popular natural food that contains prebiotic. We love veggies because they are so versatile. Veggies can be used in many different meals, as a garnish, as a side dish, or even as the main dish. Raw onions, beans, and chicory root are all very high in how much prebiotic are present in them. We recommend buying these and all you're other veggies at a farmers market as well, or somewhere where there is an organic section. This way you are getting the best possible veggies for yourself. If you want to get a ton of probio lite , try making a shake. Add Greek yogurt, spinach, bananas, and some other fruits and veggies for a great prebiotic shake that will be sure to make your digestive system extremely happy.
