Summary
Grouping foods according to biological characteristics brings out that, in percent amino acids, legumes rank highest, animal foods next, and non legume foods lowest. In pounds of amino acid produced per acre, legumes rank highest and non legumes second, with animal foods having appreciably smaller values. The average pounds of eight amino acids produced per acre are presented in graph form. Soy beans have the highest values for the eight acids, and pecans the lowest. The number of people that could be supplied with each amino acid with average production per acre of the 36 foods indicates that threonine is highest in amount, closely followed by isoleucine, valine, lysine, and leucine. Methionine production per acre would support about one-sixth the number of people that threonine will. These data point out the need for procedures that would increase the biological value of plant and animal proteins.
