Dairy foods contain high-quality protein. Milk has all the essential amino acids, so it's as good as meat or fish as a source of protein. One 8-ounce glass of milk or an ounce of cheese provides 8 grams of protein. Fat-free milk is one of the leanest protein sources available.
A small amount of milk protein, when combined with vegetable protein, markedly boosts the nutritional quality of vegetable protein.
Milk is a superb source of riboflavin, a B vitamin necessary to convert food into energy. An eight ounce glass of milk or a cup of yogurt provides 25 percent of your daily needs for this nutrient.
Milk, yogurt and cheese are our body's best sources of calcium. One 8-ounce cup of milk provides 30 percent of your daily requirement, and it is more readily absorbed than calcium from other sources. Calcium helps build bone mass and maintain bone density. Because of this, it is an important food in preventing osteoporosis.
Milk provides vitamin D, a nutrient essential for optimal absorption of calcium and bone mineralization. An 8-ounce glass gives you 25 percent of the recommended daily intake.
Milk is a great fluid for after exercise. It has water for hydration, calcium and electrolytes like potassium and sodium to replace what's lost in sweat, carbohydrate to replace energy in muscle, and protein to speed recovery.
