In an effort to find a combination of very cheap foods that might be used as a basis for the dietary in low-income groups, four food combinations, which had been calculated for adequacy and for which menus had been prepared, were assayed for certain vitamins and minerals; their adequacy for the rat was also tested. Two higher-cost food mixtures, designed for adequacy according to the suggestions of Carpenter and Stiebeling, and a stock ration for rats were similarly assayed and fed. Results showed that two of the low-cost food mixtures were similar to the higher-priced mixtures in their vitamin and mineral contents and in the growth response produced in animals. The cheaper food mixtures cost approximately half as much as the higher-priced ones.
