我们调查的饮食的影响，城市化的人口塞罗Jazmín，在墨西哥的米斯特卡阿尔塔地区（公元前300年至公元300年）的晚期和终端形成的城市中心。我们重建城市饮食区系分析和同位素结果从24个人恢复正式埋葬。骨胶原和骨和釉质磷灰石同位素数据提供了描述饮食和母乳喂养模式的C、N和O值。碳值表明，饮食狭窄，主要是玉米和少量动物蛋白。0-3岁的个体的氮和氧值明显高于成年人，这表明这些婴儿在死亡时可能仍在母乳喂养。断奶可能发生在3至5岁之间，当C3食物，可能是南瓜，在断奶饮食中补充玉米。同位素和动物区系证据表明，Cerro Jazmín人并没有通过狩猎或诱捕野生动物来补充他们的饮食。相反，动物蛋白来自驯养动物，主要是喂食富含C4饮食的狗。数据表明，城市居民的饮食自主性很小，可能完全依赖城市粮食生产和分配系统来提供大部分饮食。
We investigate the dietary impact of urbanism on the population of Cerro Jazmín, a Late and Terminal Formative urban center in the Mixteca Alta region of Mexico (300 BC-AD 300). We reconstruct the urban diet from faunal analysis and isotopic results from 24 individuals recovered from formal burials. Bone collagen and bone and enamel apatite isotopic data provide C, N, and O values describing diet and breastfeeding patterns. Carbon values suggest a narrow diet heavily based on maize and little animal protein. Individuals 0–3 years of age had significantly higher nitrogen and oxygen values than adults, suggesting that these infants may have still been breastfeeding at the time of death. Weaning likely occurred between 3 and 5 years of age when C3 foods, perhaps squash, supplemented maize atole in the weaning diet. Isotopic and faunal evidence suggest that the Cerro Jazmín population did not supplement their diet by hunting or trapping wild animals. Instead, animal protein came from domesticated animals, mainly dogs that were fed a C4 rich diet. The data suggest that urban dwellers had little dietary autonomy and may have fully relied on the urban food production and distribution system for the bulk of their diet.
