Show Will Add 7 More Years to Normal Life of Man Science Also Promises More Virile Race. Chicago. The chemistry of nutrition Is building a scientific structure which gives assurance of longer life and a more virile race. This Is the theme of a report to the symposium of the agricultural and food division of the American Chemical society by Prof. Henry C. Sherman of the department of chemistry of Coluiifbia university. The report was presented during the eighty-sixth meeting of the society, designated as the "Century of Progress meeting." More than 3,000 chemists attend the sessions. Recent researches show men and women now are taller than their ancestors. an-cestors. Chemistry, holding the key to the understanding of the nutritional nutrition-al processes in plant and animal life, promises to make humanity more sturdy and longer lived, according to the report Expectation of Life. The expectation of life, Professor Sherman holds, will be extended from the age of seventy to the age of seventy-seven. Man In bis chosen tafks will be at the height of his powers at sixty-five Instead of fifty-eight years. The age at which It Is difficult ft) get Jobs In a new field, now commonly-put commonly-put at forty-five, will be fifty-two. Adults nearing sixty should learn as readily as the young, the food chemist avers, for psychology has determined that the capacity for learning Is undiminished un-diminished at middle age. Age will yield less readily to youth, he adds, anl men and women of more advanced years will rule to a greater extent In humarr affairs. All this will emerge from an Improved Im-proved internal environment, which,, passed on to succeeding generations, will form a bulwark against disease, enlarge the prime of life, and postpone senility, Doctor Sherman asserts. "While chemistry will not make blonds of brunettes, It will, by providing pro-viding this superior environment, make men and women more powerful constitutionally, con-stitutionally, If not larger, and aid In the development of muscular strength through increased particpation ia sports and right living." Doctor Sherman Sher-man said. "We should be mindful, nevertheless, nev-ertheless, that buoyant health Is not a monopoly of larger people. An Improved Environment. "We are learning what things to feed Into the body In order that It -may be helped to maintain a more constantly optimal chemical environment environ-ment within, and we have reason to anticipate that such chemical Improvement Improve-ment of the internal environment may be favorable to those developments of mind and spirit which are In some way linked with the higher health of the body. "The dramatic' series of discoveries regarding the existence In food and the significance in nutrition of a whole group of substances not particularly related in their chemical natures or nutritional functions, commonly called 'vitamins.' demonstrate Impressively the rapidity with which many fundamentally funda-mentally Important discoveries hava been made in the past few years. "In our experiments at Columbia university we have families of rats which are thriving In the twenty-seventh generation on uniform diet," Professor Sherman continues. "Yet. on enriching the already adequate ade-quate diet in certain of its chemical factors there results an improvement in the general nutritional condition. Growth is more rapid and efficient, the death rate drops, vitality Is higher at" all ages, average longevity Increases 10 per cent, and the prime of life Is extended." The diet on which rats thrive Is enriched en-riched by Increasing the proportion of "protective foods," milk, fruit, vegetables, vege-tables, and eggs, Fro'essor Sherman states. |
