Prebiotics is a general term to refer to chemicals that induce the growth or activity of microorganisms (e.g., bacteria and fungi) that contribute to the well-being of their host. The most common example is in the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome.
Probiotics are food products that contain enough live bacteria to change the composition of the consumer's gut bacteria, and have the potential for health benefits, the AAP says.
