The dairy group includes foods that are made from milk. Milk is a good source of calcium. This is a nutrient that builds strong bones. Dairy foods also provide potassium, vitamins A and D, and protein.
If you're lactose-intolerant, it may help to use lactose-reduced, or lactose-free, dairy products.
If you're don't drink milk or eat dairy products, be sure to get your calcium from leafy greens, such as spinach, kale, or collard greens, and from calcium-fortified foods, such as orange juice and soy products.
