Medical researchers are finding that one of the keys to good health could be living in our guts – specifically, in the world of bacteria that live in our digestive tracts. Researchers are discovering that this “good” bacteria helps not only to stimulate digestive health, but may stimulate a healthy immune system.

It is the "bad bacteria" that cause disease. "Good bacteria" called probiotics work with the body’s immune system to keep the bad microbes at bay by crowding them out. In the symbiotic relationship between good and bad microbes, recent research has uncovered the importance of these good bacteria. “The good bacteria – and this is where probiotics come in – keep the bad microbes in small numbers. But they also stimulate the immune system and improve our digestive function.
