In preceding chapters data are presented which show the basis of the establishment of dietary habits which in great measure would bring about within two generations a return to physical standards in man closely approximating the best which have been realized in human history. There is nothing more important than the institution of dietary reforms in accordance with the scientific knowledge set forth in these pages. The validity of the conclusions drawn from human experience and animal experimentation has already been verified in several places by the scientific feeding of school children. Notable among these are the triumphs of Mrs. Ira Couch Wood of Chicago (4), and of Miss Maude A. Brown of Kansas City, Mo. (5). These results have been obtained essentially by liberal feeding of milk to undernourished school children. They represent the degree to which children who have been badly started in life and who are suffering from retardation of growth and other physical handicaps respond merely to proper feeding and rest. This tends to overcome the injurious effects of diseased tonsils, poor and infected teeth and other ailments which many have believed the clinic could successfully cope with only by means of surgery.
