Kefir Tolerated by Lactose-Intolerant Adults

For lactose-intolerant adults, drinking fermented milk can eliminate or drastically reduce symptoms related to lactose intolerance, according to the American Dietetic Association. Researchers believe microbes in this fermented milk -- called kefir -- possess the enzyme necessary to digest lactose. Kefir is slightly more expensive than plain milk. It tastes slightly tart and has the consistency of liquid yogurt.
