Probiotics, which means "for life," refers to friendly bacteria that can have health benefits for the body and which aid in fighting harmful bacteria. There are many different types of probiotics, with different strains having a variety of uses.

History

Russian scientist and Nobel Prize recipient Ilya Metchnikoff was the first to note the positive role this bacteria could play in the body, although the term "probiotics" was not coined until 1953.

Digestion

Probiotics are commonly known for their aid in digestion, including treating diarrhea, fighting irritable bowel syndrome and improving colitis. Managing lactose intolerance is another common use for probiotics.

Cardiovascular

Recent research has shown some benefits from probiotics in lowering cholesterol and blood pressure, along with preventing heart disease.

Cancer

According to a report by the World Health Organization, some evidence shows that probiotics may play a role in preventing certain types of cancer.

Prevention

Probiotics are useful for many types of ailments. But they are also recommended to healthy individuals for their ability to keep the bacteria inside the body balanced and help in the prevention of certain diseases.

Supplements

Probiotics can be found in certain dairy products, including yogurts and soy milk. Supplements with probiotics included in them are also available in capsules, powder or tablets.
