Potential of probiotics in controlling cardiovascular diseases

Sir, The World Health Organization and the Food and Agriculture Organization of the United Nations have defi ned probiotics as “live microorganisms, which, when administered in adequate amounts, confer a health benefi t on the host.” They are also called “friendly bacteria” or “good bacteria.” The concept of probiotics arose at the turn of the 20th century from a hypothesis fi rst proposed by the Noble Prize-winning Russian scientist, Elie Metchnikoff. Most probiotics fall into the group of organisms known as lactic acid-producing bacteria, and are normally consumed in the form of yogurt, fermented milks or other fermented foods.[1,2] The valuable effects of food with added live microbes (probiotics) on human health and, in particular, of milk products, are being increasingly promoted by health professionals, and these probiotics can play an important role in systemic health of the person.
