尽管历史文献描述了一般的饮食菜单，但江户时代城镇居民的个体饮食差异（例如性别、年龄、时期和地区）尚不清楚。我们对日本江户时代（公元 17 世纪末至 19 世纪末）池之端七间町遗址出土的 103 具成人骨骼进行了碳和氮稳定同位素分析，以调查江户市城镇居民的个体饮食差异。池之端町居民的平均碳同位素比和氮同位素比分别为 -19.7 +/- 0.4 ppm 和 10.8 +/- 0.7 ppm，这表明基于 C-3 的陆地食物、淡水鱼和海鱼是他们的主要膳食蛋白质来源。人群内比较表明，除了中晚期（18 世纪下半叶）碳同位素比率（千分之 0.37）存在性别差异外，不同性别、年龄类别和时间顺序的个体之间没有显着差异。池之端数据与之前研究结果的比较显示，同一社会阶层（氮高达 1.33 ppm）和同一江户城市（氮高达 1.64 ppm）的骨骼种群存在显着的同位素差异。尽管这些差异在稳定同位素生态方面相对较小，但江户时代人们的饮食食物来源会因社会阶层和居住地理区域而有所不同。
Individual dietary differences (e.g. sex, age, period, and region) among townspeople during the Edo period are unclear, although the historical literature describes the general dietary menu. We applied carbon and nitrogen stable isotope analyses to 103 adult human skeletons excavated from the Ikenohata-Shichikencho site of the Edo period (late 17th to late 19th century AD) in Japan to investigate individual dietary differences among townspeople in the city of Edo. The mean carbon and nitrogen isotope ratios of Ikenohata townspeople were -19.7 +/- 0.4 parts per thousand and 10.8 +/- 0.7 parts per thousand, respectively, which suggests that C-3-based terrestrial foods, freshwater fish, and marine fish were their main dietary protein sources. Intra-population comparisons indicated no significant difference among individuals of different sexes, age categories, and chronological periods, with the exception of a sex difference in carbon isotope ratios (0.37 parts per thousand) during the Middle Late period (last half of 18th century). Comparison of the Ikenohata data with the results of previous studies revealed significant isotopic differences in skeletal populations of the same social class (up to 1.33 parts per thousand for nitrogen) and same Edo city (up to 1.64 parts per thousand for nitrogen). Although these differences were relatively small in terms of stable isotope ecology, dietary food sources for people during the Edo period would differ to some extent by their social class and geographic region of residence.
