Clinical Applications of Probiotics

For some decades now, bacteria known as probiotics have been added to various foods because of their beneficial effects for human health. Examples of foods containing probiotics are yogurt, fermented and unfermented milk, miso, tempeh, soy beverages and some juices. Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics; but certain yeasts and bacilli may also fit the bill. These can also be formulated into drugs and dietary supplements. Probiotics are also called "friendly bacteria" or "good bacteria". They are gaining importance because of the innumerable benefits, e.g. treating lactose intolerance, gastroenterititis infection, allergies, dental caries, inflammatory bowel disease and hypercholesterolemia. With the current focus on disease prevention and the quest for optimal health at all ages, the probiotics potential could reign high. This article discusses the summary of research on the health benefits of probiotics and offers practical information to help health professionals and even the layman.
