Probiotics are microorganisms, usually bacteria, used in certain foods as dietary supplements. The word "probiotics" is of Greek origin, meaning "for life."
History
Russian physiologist Elie Metchnikoff (1845-1916) is credited with establishing the concept of probiotics as the first person in history to suggest that eating bacteria could be beneficial to health. Metchnikoff based his theory on the diet of Bulgarians who ate fermented dairy products like yogurt.
Research
In 1907, Metchnikoff theorized that bacteria in fermented dairy products could cleanse the large intestine and contribute to prolonging life. Decades after Metchnikoff, microbiological and clinical research have backed up his theories and studies.
Availability
Probiotics are either already present in foods or can be added to them. Foods that contain probiotics include yogurt, fermented and unfermented milk, and soy beverages.
Uses
Probiotics are mainly used to assist in strengthening the immune system. They do this by killing microorganisms that cause disease.
Significance
Although probiotics have been around for thousands of years, it was not until the 20th century that most people were aware of its benefits. According to the National Institutes of Health, spending on probiotic supplements in the United States nearly tripled from 1994 to 2003.
