Probiotics was derived from Greek which literally means “for life”. The term was first coined in 1965 to depict substances produced by a certain microorganism to stimulate the growth of another microorganism. Current definition of probiotics was made by Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO), referring to “living microorganisms which when administered in adequate amounts confer a health benefit to the host”. To quality as a probiotic, four characteristics must be found in a microorganism: reside in human body, survive after ingestion, benefit the host, and is safely consumed. Gastrointestinal (GI) tract is the most common place for probiotics to live, but there are several other locations, such as mouth, vagina, urinary tract, skin and lungs, suitable for some probiotics. https://probiotic.creative...
