Always choose fat-free (skim) or low-fat (1%) dairy products, and try to consume 3 cups total per day. Cheese is also a healthy choice, but only in moderation. Limit your intake to 1.5 ounces of hard cheese per day.
Other good dairy choices are milk and buttermilk. Yogurt is best when it is fat-free or low-fat. Plain yogurt that you stir your own fresh or dried fruit into is better than fruit-flavored yogurts, which can contain added sugars.
Cream cheese, cream, and butter are not healthy dairy products.
