You've probably heard about probiotics, but do you know what they are? The World Health Organization says probiotics are tiny living organisms such as bacteria, viruses, and fungi. You cannot see them, but they are said to provide health benefits.
Here's one example of friendly bacteria. Yogurt usually contains a specific type of bacteria that aids in digestion. Some people even eat yogurt to replace the friendly bacteria in the gut that are killed by taking antibiotics. People who have the condition called lactose intolerance take supplements that contain probiotics. The probiotics help them digest the sugars in milk, cheese, and ice cream without getting a stomach ache or cramping.
Researchers are also exploring ways that friendly bacteria can be used to treat diarrhea, prevent urinary infections, and ease the symptoms of irritable bowel syndrome, according to the National Center for Complementary and Alternative Medicine.
Even though research continues, there is still limited evidence to support the use of probiotics. NCCAM recommends that you talk with your doctor about the use of any product containing probiotics. The quality of probiotic products can vary in potency and purity, and side effects can range from mild (bloating) to serious (infection). |
