Lactose is a sugar present in cow's milk. Not everyone can digest milk sugar; these people are known as lactose intolerant. For a Lactose intolerant person, it is important to know how much lactose is in a food. Many lactose intolerant people can actually tolerate a small amount of lactose without discomfort. Some common ingredients, like whey, are high in lactose but may not be immediately recognized as a milk product.
