It’s Alive! Yogurt's Health Secret is Live Bacterial Cultures

“Cow’s milk yogurt is packed with calcium, protein and Vitamin D,” says Althea Zincowski, a spokesperson for the American Dietetic Association. People who are allergic to milk products, or very lactose intolerant, can try a non-milk soy-based yogurt. Most, but not all of the lactose (natural milk sugar) in yogurt is digested by beneficial bacteria, so the majority of lactose-intolerant people can eat yogurt unless they are very sensitive. For a more exotic flavor or animal alternative to cow’s milk, there are also goat’s milk and sheep’s milk yogurts.
