We report isotopic data (delta(2)H, delta(18)O n = 196; delta(13)C, delta(15)N n = 142; delta(34)S n = 85) from human hair and drinking water (delta(2)H, delta(18)O n = 67) collected across China, India, Mongolia, and Pakistan. Hair isotope ratios reflected the large environmental isotopic gradients and dietary differences. Geographic information was recorded in H and O and to a lesser extent, S isotopes. H and O data were entered into a recently developed model describing the relationship between the H and O isotope composition of human hair and drinking water in modern USA and pre-globalized populations. This has anthropological and forensic applications including reconstructing environment and diet in modern and ancient human hair. However, it has not been applied to a modern population outside of the USA, where we expect different diet. Relationships between H and O isotope ratios in drinking water and hair of modern human populations in Asia were different to both modern USA and pre-globalized populations. However, the Asian dataset was closer to the modern USA than to pre-globalized populations. Model parameters suggested slightly higher consumption of locally produced foods in our sampled population than modern USA residents, but lower than pre-globalized populations. The degree of in vivo amino acid synthesis was comparable to both the modern USA and pre-globalized populations. C isotope ratios reflected the predominantly C(3)-based regional agriculture and C(4) consumption in northern China. C, N, and S isotope ratios supported marine food consumption in some coastal locales. N isotope ratios suggested a relatively low consumption of animal-derived products compared to western populations.
我们报告了来自中国、印度、蒙古和巴基斯坦的人类头发和饮用水的同位素数据（δ 2 H、δ 18 O n = 196；δ 13 C、δ 15 N n = 142；δ 34 S n = 85）。头发同位素比值反映了大的环境同位素梯度和饮食差异。地理信息记录在 H 和 O 同位素中，在较小程度上记录在 S 同位素中。H 和 O 数据被输入到一个最近开发的模型中，该模型描述了现代美国和全球化前人群中人类头发和饮用水的 H 和 O 同位素组成之间的关系。这在人类学和法医学中有应用，包括重建现代和古代人类头发中的环境和饮食。然而，它尚未应用于美国以外的现代人群，我们预计那里的饮食不同。亚洲现代人类群体的饮用水和头发中 H 和 O 同位素比值之间的关系与现代美国和全球化前人群都不同。然而，亚洲数据集更接近现代美国，而不是全球化前人群。模型参数表明，与现代美国居民相比，我们抽样人群中本地生产食品的消费略高，但低于全球化前人群。体内氨基酸合成的程度与现代美国和全球化前人群相当。C 同位素比值反映了以 C(3)为主的区域农业和中国北方的 C(4)消费。C、N 和 S 同位素比值支持一些沿海地区的海洋食物消费。N 同位素比值表明与西方人群相比，动物源性产品的消费相对较低。
