本研究探讨了饮食和生理对骨骼和牙齿磷酸盐（δ18Op）的氧同位素比的潜在影响，这些木乃伊来自于X组（公元350年至550年）至基督教（公元500年至1400年）时期的尼罗河努比亚木乃伊。δ 18 Ops值表明尼罗河是这些人群的主要饮用水源。骨胶原的δ 18OP值和δ13C值反映了在X组时期尼罗河水含量的下降和相关的饮食向C4植物消费的转变。与铁缺乏相关的代谢变化对δ 18OP值没有显著影响，但骨质疏松女性和一般女性的δ 18OP值略低于男性。断乳过程在骨骼和牙齿中都很明显，但其表达方式存在差异。提出了几种假设来解释这种变异性。这些数据表明，人类更复杂的饮食和文化行为可能会限制我们采用动物模型来解释δ18Opvalues的能力。
This study examines the potential effects of diet and physiology on the oxygen-isotope ratios of bone and tooth phosphate (δ18Op) from Nilotic Nubian mummies dating from the X-Group (AD 350 to 550) to Christian (AD 500 to 1400) periods. The δ18Opvalues indicate that the Nile was the main source of drinking water for these populations. A drop in the level of the Nile and the associated dietary shift to C4plant consumption during the X-Group period is reflected in δ18Opvalues and δ13C values of bone collagen. Metabolic changes associated with iron deficiency do not affect δ18Opvalues significantly, but females with osteopenia, and females in general, have slightly lower δ18Opvalues than males. The weaning process is evident in both bones and teeth, but there is variability in how it is expressed. Several hypotheses are presented to explain this variability. The data suggest that the more complex dietary, and cultural behaviour of humans may limit our ability to adopt animal models in the interpretation of δ18Opvalues.
