Probiotics History: Background Information
The root of the word probiotic comes from the Greek word pro, meaning “promoting” and biotic, meaning “life.” The name probiotic is said to mean “for life”: pro + bios = “for life”. The beginning of the probiotics concept is credited to Nobel Prize recipient Eli Metchnikoff. In the year 1907, Eli put forward 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”. Probiotics in Spanish are called probióticos
What does the US Food and Drug Administration(FDA) say or recommend on probiotics?
FDA neither have a governing definition of probiotics nor a central office that is solely allocated to handle probiotics.
In the year 2005, Julienne Vaillancourt, a member FDA’s of CBER (Center for Biologics Evaluation and Research) disclosed in a presentation that the term probiotics has no standard definition.
FDA uses alternative terms to define probiotics for regulatory purposes. Live microbes or probiotics, particularly those intended for animals are referred to as direct-fed microbials. Microbes intended for human use are referred to as live biotherapeutics. It is not just in the United States that probiotics lack a legal definition, it is all the same in other countries.
Points to Note:
- A probiotic is not just any microorganism but mostly Bacteria and Yeast
- Never should you confuse probiotics with prebiotics. Prebiotics are complex sugars (such as lactulose, lactitol, a variety of fructo-oligosaccharides and inulin) that are used as fuel by the healthful bacteria to stimulate their growth and activity while suppressing the growth and activity of harmful organisms.
