抄録

Carbon and nitrogen isotope ratios of human diets and hairs were studied for seven ethnic populations. The protein fraction of Japanese food purchased at Tokyo showed similar δ13C and δ15N with those of previously reported American foods. Based on representative isotope ratios of food classes, the carbon and nitrogen isotope ratios of human hairs were estimated for each populations. The estimation was illustrative of observed isotopic differences of hairs of examined populations except of Brazilian. A mixing model of plant and animal diets was developed to study the relation between the δ15N of hair and the animal protein dependence of each nation. The δ13C and δ15N of Japanese hairs, from foreign residents or from Edo era (ca.130 years BP), showed quite different values as compared with those of recent native Japanese. These suggest that the carbon and nitrogen isotope ratios of human tissues were characterized mainly by food preferences and the isotope ratios of foods, but not by ethnic factors.
