The function of zinc in the nutrition of man has been studied by numerous investigators in an attempt to determine the needs of the body for this element. To date no deficiency disease has been produced by a zinc-deficient diet and cured by the addition of this element to the diet. The only criteria thus far presented to establish its essentialness in the dietary of man are the facts that zinc is retained by the body and that its presence is necessary for normal functioning of other nutrients. This study was made to observe zinc metabolism of young college women on self-selected diets, to see if a requirement for zinc intake in humans could be established.

This study was undertaken to determine the cobalt intake in food and milk, and the excretion of cobalt in the urine and feces of young college women living in the home management house at the North Texas State College and consuming a self-selected diet. Cobalt as a trace inorganic element has long been recognized according to Martin (1945) as a nutritional essential in ruminants in whom cobalt deficiency is a typical anemia. For that reason emphasis has been placed upon studies with ruminants, since it seems logical to use a species for which cobalt is known to be essential.
