The amino acid nutrition in both of the farming village of coast district and the forestry village of mountain district in Kagoshima Prefecture was compared with each other. The amino acid intake in the both districts was more than all the safe daily intake values suggested by Leverton, Rose and the FAO Committee. Protein scores in the both districts were almost the same, 81-82. The E/T of the two were about 2500, which are far more than that of the reference protein (FAO(1957)), 2020. The values of chemical scores, egg, human milk and cow's milk scores, were just or almost the same in the two districts, 70, 89 and 83-84 respectively, the limiting amino acids of which were sulfur containing amino acids, tryptophan and lysine, respectively. Little correlation was observed between all the above scores and each nutrient intake, and especially no correlation between E/T and each nutrient. In the both districts the positive correlation was observed between both cow's milk score and animal protein ratio or intake, and human milk score and cow's milk score. Also, the negative correlations were observed between both egg score and intake of soybean, and cow's milk score and cereals intake, while in the coast district the positive one was between cow's milk score and intake of fishes.
