Dairy refers to milk and any part of milk that comes from cows and other mammals. So to be dairy-free, a product must have no milk and no part of milk. Lactose, on the other hand, is merely an ingredient in milk, or a part of milk. It is the sugar component of dairy products. So a product that is dairy-free will not have lactose in it.
Lactose is the sugar in milk and casein is the protein. Casein-free foods may still contain lactose. An individual with a milk allergy who would react to casein must learn to read labels on nearly everything. The word non-dairy does not mean the product is a casein-free food. Other terms listed on a label that indicate it contains casein may be milk proteins, milk solids, caseinates, fortified proteins, and curd. Finding casein-free foods to incorporate into the diet takes some research and learning.
