Abstract Faba beans ( Vicia faba L.) of four cultivars, one of which was harvested in batches during the 2 months prior to normal harvesting time, and for comparison, a sample of kidney beans ( Phaseolus vulgaris L.) had similar amino acid compositions with sulphur amino acids limiting in all samples. Chemical scores ranged from 45–52 and all the faba beans, when fed to rats, gave biological values in close agreement with the chemical score. Diets containing two of the cultivars were supplemented with 0.1% methionine and in both instances an increase in biological value of 22 units was obtained. Kidney beans fed to rats at the same level of crude protein resulted in the death of animals in 7–9 days. The haemaggfulinin content of the faba bean samples was 8–16 times lower than in kidney beans. Early harvesting did not affect the nutritive value of the faba beans and no differences were observed between the different cultivars, none of which showed any evidence of toxicity.
