Prebiotics Versus Probiotics: The Difference

Prebiotics

Probiotics
Probiotics are live microbes. See probiotics explained.
Food sources
Onions, garlic, bananas, oats and beans offer prebiotic fibers. Yogurt and kefir contain live cultures.
Side effects
Large amounts of prebiotic fiber can cause gas and bloating. Increase slowly.
