These two essential and complementary minerals are found together in milk, and in a ratio beneficial to the absorption and utilization of the two elements. Calcium is needed for regular muscle function as well as for strong bones. Phosphorus is involved in nearly all metabolic functions, including heart and muscle contraction, the digestive processes, and the transfer of cellular energy. What we don’t need are the excess fats contained in whole--milk products. Ninety --nine percent fat--free milk provides a good compromise: a small amount of fat to aid nutrient absorption especially of the fat--soluble vitamins A and D, usually added to milk.
