Prebiotics are types of dietary fiber that feed the friendly bacteria in your gut while Probiotics are live bacteria and yeasts that are good for you, especially your digestive system.
However, prebiotics should not be confused with probiotics. The types of fiber that the human body cannot digest serve as food for probiotics which are tiny living microorganisms, including bacteria and yeast. Both prebiotics and probiotics may support helpful bacteria and other organisms in the gut.
List of Healthy Probiotic Foods You Should Eat:
