The Meaning of Probiotic
Probiotic is a word that has been around in academia and food research labs for several decades, mainly in Europe and Japan. But it has only been in recent years that the topic has begun to be discussed more widely in most parts of the world by health professionals, groups promoting healthy food and lifestyle, and indeed the general public.
In the past it was not uncommon for most people to understand that all bacteria were bad and harmful, and caused disease. While this is certainly the case with many types of pathogenic microbes such as listeria, clostridium, and salmonella, to name a few, there are also many types of “good” bacteria that may indeed provide health benefits to people who consume them. The most common of these beneficial bacteria belong to the genera of lactobacillus and bifidobacterium.
The word “Probiotic” has its roots from a combination of the Latin word “pro” and the Greek word, “bios”, meaning “for life” or “to promote life”. Although the definition of probiotic has evolved over time, the most readily accepted one is that which has been adopted by the Food and Agriculture Organization and the World Health Organization of the United Nations, which states that probiotics are “live microorganisms, which when administered in adequate amounts, confer a beneficial health effect on the host”. It is understood that these microorganisms comprise of multiple species and sub-species of bacteria, as well as some species of yeast, and that they do not promote or cause disease.
