Many probiotics provide benefits by adjusting the microflora (the natural balance of organisms) in the intestines, or by acting directly with body functions, such as the digestion tract or the immune system. 

And since yogurt comes from milk, consumers will get a dose of animal protein (approximately 9 grams per 6-ounce serving).  Nutrients also found in dairy foods, such as calcium, vitamin B-2, B-12, potassium, and magnesium are present as well. In fact, the benefits of yogurt are so significant that many health-conscious people make it a daily habit.

Researchers around the world have studied the attributes of yogurt which include  boosting the body's immune system, aiding in protein digestion and helping prevent osteoporosis.  Additional research is being conducted to establish a more definitive link between yogurt and the above health benefits.

The live and active cultures found in yogurt also break down lactose in milk. This allows some who are lactose intolerant and who occasionally experience gastrointestinal discomfort to eat yogurt and receive the nutrients contained in the milk product without the side effects of abdominal cramping, bloating and indigestion.  Additional research is being conducted to further these claims.
