Yogurt contains active bacterial cultures that "eat" the milk sugar (lactose), making yogurt a great dairy product for those people who have a milk intolerance.

Rather than being caused by an overenthusiastic immune system, milk intolerance, for example, results from a lack of the enzyme the body needs to break down lactose, the main sugar in milk.

Lactose intolerance is the inability to digest lactose, the sugar found in milk.
