nutritious foods

Executive Summary Except in cases of milk allergy (an uncommon problem), cows' milk and its products are acceptable, nutritious foods for persons one year of age and older. Milk and dairy products are good sources of high-quality protein and several vitamins, and they are the best food source of the mineral calcium, a nutrient often not plentiful enough in the American diet. It is difficult to obtain an adequate supply of calcium from non-dairy sources, and it requires heavy reliance on foods not favored by most Americans.
