Excerpt from Why and How to Use MilkMilk and its products are indispensable to the growth of the child and to the health of the adult. For these, there is no substitute. For the infant, milk is a perfect food, for the growing child, milk and the products of the dairy are essential foods, and for adults, they are the most important foods.Food is not merely something to chew. It must furnish material for the growth and repair of the body, material for body heat and energy, and material for use by the body as regulating substances. Milk fulfils all these requirements. It contains protein, from which the body builds new cells and repairs worn-out tissues. It contains fat and sugar, which serve as a source of heat and energy for muscular activity, and contains mineral matter which has a regulatory effect and which enters into the composition of the body, especially the bones and teeth.Not only does milk supply these demands, but it contains also the essential food factors, or vitamines, - Fat-soluble A, Water-soluble B, and Water-soluble C, without which normal growth is impossible and without which the health of the adult cannot be maintained.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
