Stable carbon and nitrogen isotope analyses were conducted to investigate dietary variation in human skeletons (n = 109) from the Gaya cemetery at Yeanri located near Gimhae City, South Korea. The cemetery contained three distinct grave types dating to 4th-7th century AD. The main purposes of this research were to reconstruct palaeodiet in the Gaya population and to explore correlations between stable isotope compositions and burial types, inferred age, and sex of these individuals. The isotopic data indicate that the people at Yeanri consumed a predominantly C(3)-based terrestrial diet supplemented with freshwater and/or marine resources. The comparison of isotopic results reveals significant differences in delta(13)C values among three adult burial types (wood-cist coffin: -18.5 +/- 0.5 per thousand, stone-cist coffin: -18.1 +/- 0.6 per thousand, mausoleum: -17.8 +/- 0.9 per thousand). Males in wood-cist and stone-cist coffins have relatively more elevated mean delta(13)C and delta(15)N values than females. The isotopic ratios from the two adult age groups (21-40 years and 40-60 years) indicate that there was no significant dietary change in individuals with age. The isotope data from the infants and children suggest the weaning was a gradual process that was completed between 3 and 4 years of age in the Gaya population. This evidence indicates that the dietary variations within the cemetery reflect social status, sex, and childhood consumption patterns.
对位于韩国金海市附近 Yeanri 的 Gaya 公墓的 109 个人骨进行了稳定碳氮同位素分析，以研究人类的饮食变化。该墓地包含三种不同类型的坟墓，可追溯到公元 4 世纪至 7 世纪。本研究的主要目的是重建 Gaya 人群的古饮食，并探讨稳定同位素组成与埋葬类型、个体年龄和性别的关系。同位素数据表明，Yeanri 的人们主要食用以 C(3)为基础的陆生食物，并辅以淡水和/或海洋资源。同位素结果的比较表明，三种成人埋葬类型（木棺：-18.5 +/- 0.5 per thousand，石棺：-18.1 +/- 0.6 per thousand，陵墓：-17.8 +/- 0.9 per thousand）之间的 delta(13)C 值存在显著差异。木棺和石棺中的男性的平均 delta(13)C 和 delta(15)N 值比女性相对较高。来自两个成人年龄组（21-40 岁和 40-60 岁）的同位素比值表明，个体年龄的增长并没有导致饮食的显著变化。婴儿和儿童的同位素数据表明，在 Gaya 人群中，断奶是一个逐渐的过程，在 3 到 4 岁之间完成。这一证据表明，墓地内的饮食变化反映了社会地位、性别和儿童的消费模式。
