通过对伊顿公学赛艇课程中发现的人类遗骸的同位素调查，我们研究了从新石器时代到罗马时期饮食的变化。人类的同位素特征表明他们的饮食以C3陆地资源为基础。人类δ13C值与时间呈显著相关，而δ15N值与时间无显著相关。伊顿的动物同位素数据分布不均匀，因此很难确定人类的值是否反映了动物的值。为了评估伊顿公学的结果是否具有代表性，我们将我们的结果与新石器时代至罗马时期其他英国遗址的同位素数据进行了比较。在这段时间内，我们发现人类和主要驯养食草动物的平均δ15N之间存在很强的相关性，两者之间的偏移量为~ 4.5‰。因此，人类同位素值的变化可能与食草动物同位素特征的变化有关，而不是与人类饮食中蛋白质组成的变化有关。相比之下，人类的平均δ13C与主要驯化食草动物的δ13C之间没有明显的时间关系，两者之间的偏移量为~ 1.4‰。然而，在人类和牛的平均δ13C之间观察到微弱的相关性，这可能解释了人类δ13C值在不同地点之间的一些变化。人类和动物δ13C平均值之间没有很强的相关性，这表明影响站点之间人类δ13C值的主要因素是饮食组成。δ13C和δ15N之间缺乏共变异，可能反映了日粮宏量营养素的不同表征。考虑到氮的结果表明动物蛋白的消耗模式在不同的地点是相似的，人类δ13C在不同地点之间的变化可能反映了饮食中的植物部分。
Through isotopic investigations of directly dated human remains recovered from the Eton College Rowing Course, we examine changes in diet from the Neolithic to the Roman period. The human isotope signatures point to a diet based on C3 terrestrial resources. A significant correlation is visible between human δ13C values and time, but no such trend is observed in δ15N. The animal isotope data from Eton are unevenly distributed, making it difficult to determine if the human values mirror the animal values. To assess whether the results from Eton are typical, we compare our results to isotope data from other British sites dating from the Neolithic to the Roman period. Across this time period, we see a strong correlation between the mean δ15N of the humans and that of the main domesticated herbivores, with an offset of ∼4.5‰ between the two. Thus, the changes in the human isotope values are likely linked to changes in the isotopic signatures of the herbivores rather than changes in the protein composition of human diets. By contrast, no clear temporal relationship is observed between the mean δ13C of the humans and that of the main domesticated herbivores, with an offset of ∼1.4‰ between the two. There is, however, a weak correlation observed between the mean δ13C of the humans and that of the cattle, which may account for some of the variation in human δ13C values between sites. The absence of a strong correlation between mean human and animal δ13C suggests that the primary factor influencing human δ13C values between sites is dietary composition. The lack of co-variation between δ13C and δ15N is likely to reflect the different representation of dietary macronutrients. Given that the nitrogen results suggest that the animal protein consumption patterns are similar across sites, the human δ13C variation between sites is likely to reflect the plant portion of the diet.
