Fermented milk is made when bacteria change lactose (the sugar in milk) into lactic acid, which causes the tangy taste.
Fermented milk has calcium, protein, phosphorus, and riboflavin (or vitamin B2) and may improve nutritional status in children.
Bacteria present in fermented milk increase and balance the flora in the gut. These bacteria may decrease stomach problems, improve immunity, and shorten infections.
Fermented dairy foods have less lactose than milk and therefore are commonly used by lactose-intolerant people.
Fermented milk has been studied for allergies, diarrhea, infections in the gut, and improving immune function.
