In contrast to contemporaneous Byzantine and Egyptian textual accounts, little is known about medieval Nubian monastic diets. Femur samples from 30 monks interred at Ghazali monastery (occupied ca. 680–1,275 CE), Sudan were examined for δ¹³C_col and δ¹⁵N. δ¹³C averaged - 17.0‰ ± 1.0‰ (range: −14.7‰ to −19.0‰); δ¹⁵N averaged 11.3‰ ± 1.1‰ (range: 7.5‰ to 13.4‰), suggesting primarily mixed C₃/C₄ diets with variable animal protein consumption. Such data, the first from Nubian monastic contexts, bring forth questions about expected versus actual monastic diets, as well as access to foodstuffs and dietary variation over time, as the diets of the monks were not entirely uniform.

苏丹加扎利中世纪努比亚修道院马库里修道院饮食的同位素评估（公元 680-1,275 年）

与同时代的拜占庭和埃及文字记载相比，人们对中世纪努比亚修道院的饮食知之甚少。来自埋葬在 Ghazali 修道院（公元 680–1,275 年）、苏丹的 30 名僧侣的股骨样本进行了 δ ¹³ C _col和 δ ¹⁵ N 的检查。平均δ ¹³ C 为 - 17.0‰ ± 1.0‰（范围：-14.7‰ 到 - 19.0‰)；δ ¹⁵ N 平均为 11.3‰ ± 1.1‰（范围：7.5‰ 至 13.4‰），表明主要是混合 C ₃ /C ₄具有可变动物蛋白消耗的饮食。这些数据是第一个来自努比亚寺院环境的数据，提出了关于预期与实际寺院饮食的问题，以及随着时间的推移获得食物和饮食变化的问题，因为僧侣的饮食并不完全统一。
