Abstract

Dietary analysis using delta N-15 values of human remains such as bone and hair is usually based on general principles and limited data sets. Even for modern humans, the direct ascertainment of dietary delta N-15 is difficult and laborious, due to the complexity of metabolism and nitrogen fractionation, differing dietary habits and variation of delta N-15 values of food items. The objective of this study was to summarize contemporary regional experimental and global literature data to ascertain mean representative delta N-15 values for distinct food categories. A comprehensive data set of more than 12,000 analyzed food samples was summarized from the literature. Data originated from studies dealing with (1) authenticity tracing or origin control of food items, and (2) effects of fertilization or nutrition on delta N-15 values of plants or animals. Regional German food delta N-15 values revealed no major differences compared with the mean global values derived from the literature. We found that, in contrast to other food categories, historical faunal remains of pig and poultry are significantly enriched in N-15 compared to modern samples. This difference may be due to modern industrialized breeding practices. In some food categories variations in agricultural and feeding regimens cause significant differences in delta N-15 values that may lead to misinterpretations when only limited information is available.
