This paper presents the first multi-tissue study of diet in post-medieval London using both the stable light isotope analysis of carbon and nitrogen and analysis of microdebris in dental calculus. Dietary intake was explored over short and long timescales. Bulk bone collagen was analysed from humans from the Queen’s Chapel of the Savoy (QCS) (n = 66) and the St Barnabas/St Mary Abbots (SB) (n = 25). Incremental dentine analysis was performed on the second molar of individual QCS1123 to explore childhood dietary intake. Bulk hair samples (n = 4) were sampled from adults from QCS, and dental calculus was analysed from four other individuals using microscopy. In addition, bone collagen from a total of 46 animals from QCS (n = 11) and the additional site of Prescot Street (n = 35) was analysed, providing the first animal dietary baseline for post-medieval London. Overall, isotopic results suggest a largely C₃-based terrestrial diet for both populations, with the exception of QCS1123 who exhibited values consistent with the consumption of C₄ food sources throughout childhood and adulthood. The differences exhibited in δ¹⁵N_coll across both populations likely reflect variations in diet due to social class and occupation, with individuals from SB likely representing wealthier individuals consuming larger quantities of animal and marine fish protein. Microdebris analysis results were limited but indicate the consumption of domestic cereals. This paper demonstrates the utility of a multidisciplinary approach to investigate diet across long and short timescales to further our understanding of variations in social status and mobility.

使用稳定的同位素和微碎片分析对伦敦两个中世纪后人群的饮食进行多学科研究。

本文使用碳和氮的稳定光同位素分析和牙结石中的微碎屑分析，介绍了中世纪伦敦后饮食的第一个多组织研究。在短期和长期内都研究了饮食摄入量。分析了来自萨伏伊女王教堂（QCS）（n  = 66）和圣巴拿巴/圣玛丽修道院（SB）（n  = 25）的人类的大块骨胶原蛋白。对个体QCS1123的第二磨牙进行增量牙本质分析，以探索儿童的饮食摄入量。 从QCS的成年人中采集大批头发样本（n = 4），并使用显微镜从另外四个人中分析牙结石。此外，来自QCS的总共46只动物的骨胶原（n = 11），并分析了Prescot街（n  = 35）的其他地点，为中世纪后的伦敦提供了第一个动物饮食基线。总体而言，同位素结果表明，这两种人群都主要使用基于C ₃的陆栖饮食，但QCS1123除外，其在整个童年和成年期都具有与C ₄食物来源的摄入量一致的价值。在δ表现出的差异¹⁵ Ñ _COLL两种人群之间的饮食差异都可能反映出由于社会阶层和职业而导致的饮食变化，来自SB的个体可能代表了较富裕的个体，他们消费了大量的动物和海洋鱼类蛋白。微碎屑分析结果有限，但表明了国内谷物的消费量。本文展示了一种多学科方法在长短时间内调查饮食的效用，以进一步了解社会地位和流动性的变化。
