Probiotics are microorganisms that are believed to provide health benefits when consumed.[1] The term probiotic is currently used to name ingested microorganisms associated with beneficial effects to humans and other animals.[2] Introduction of the concept is generally attributed to Nobel Prize recipient Élie Metchnikoff, who in 1907 suggested that "the dependence of the intestinal microbes on the food makes it possible to adopt measures to modify the flora in our bodies and to replace the harmful microbes by useful microbes".[
