Abstract
Research with animals has shown the inability of the body to store amino acids for use at a later time, and has demon strated that the body needs to have all the essential amino acids present simultaneously and in adequate amounts for tissue synthesis (Geiger, '47; Cannon et al., '47; Schaeffer and Geiger, '47; Harte, Travers and Sarich, '48). Henry and Kon ( '46) found that the supplementary relationship of milk and potato, and of bread and cheese, did not exist if these foods were fed separately on alternate days but could be demonstrated only if the two foods were fed together. Geiger ( '48) has shown that diets containing wheat gluten -f- blood protein, or yeast + blood protein, or yeast -f- wheat gluten protein promote growth satisfactorily. Growth did not result, however, when these same pairs of proteins were fed separately during alternating 10-hour periods with two-hour intervals between feedings. The possibility warrants study that the metab olism of human subjects may be influenced by the time of in1Published with the approval of the Director as paper No. 474, Journal Series, Nebraska Agricultural Experiment Station.
