Notes:
Raw and lime-treated corn and raw and cooked beans were analyzed for nutrient content including essential amino acids. No major treatment changes were found. Eight different corn and bean combinations were tested isoproteically and isocalorically in both growing and protein-depleted adult rats. Corn protein alone gave better results than bean protein. Replacement of part of the lime-treated corn protein by cooked-bean protein improved growth up to the point where each dietary component contributed 50% of the total protein of the diet (72% corn and 28% beans by weight); thereafter growth was decreased with increasing amounts of bean protein in the diet.When the diets were supplemented with the limiting amino acids found to be deficient by comparing their amino acid pattern with that of the FAO Reference Protein, methionine proved to be the most limiting, particularly in those diets with a higher content of bean protein. The addition of lysine and methionine together improved protein efficiency further. Whenever adequate growth was obtained, higher amounts of fat were found in the liver.
