It will help in clarifying the subject to explain in the beginning that a state of good nutrition is not necessarily evidenced by one’s being tall nor by being fat. But it is evidenced by normal size and development; sound teeth and bones; hair and skin of normal color and texture; blood of the normal composition; stable nerves; vigor both mental and physical; normally functioning organs and resistance to disease, and above all that indescribable condition which is summed up as a state of general well-being. That this degree of nutritional stability is not as prevalent in this country as might be desired is disclosed by reports upon findings of the examining boards for army service, over a period of three years and physical examinations of various groups of school children throughout the country. It was found in the first case, that about sixteen per cent. of the apparently normal young men who were inspected for military service, were undernourished in some degree, and according to Dr. Thomas W. Wood, Professor of Physical Education, Columbia University, “Five million children in the United States are suffering from malnutrition.” This army of undernourished children, which represents about one-third of the children of the country, is on the broad highway to ill health, invalidism of various kinds and degrees, instability and inefficiency. They are certainly not developing into the clear-eyed, alert, buoyant individuals that go to make up good citizenry. The tragic aspect of this state of undernourishment is that though a great deal can be done to nourish and build up the malnourished child or adult, a certain amount of damage that results from inadequate nourishment during the early, formative weeks and months cannot be entirely repaired later on in life. As the baby grows and develops, certain substances are needed at the various stages of its progress, and if these are not supplied at these stages, there will always be some degree of inadequacy in the adult make up. It is much like the futility, when building a house, of using bricks without straw for the foundation instead of firm, durable rock, and then trying to make it substantial and secure later on by using good materials when constructing the upper stories. The solid foundation and substantial beams and girders for men and women are put in during infancy and early childhood in the shape of good material that forms good nerves, muscles, bones, teeth and general physical stability. It is practically impossible to make up to the older child or adult for damage caused by failure to supply sufficient nourishment to the growing, developing, infant body. “The moving finger writes; and, having writ, Moves on; nor all thy piety nor wit Shall lure it back to cancel half a line, Nor all thy tears wash out a word of it.”
