Abstract [en]

This paper deals with diet and gender in the early roman iron age in Sweden. Human bone and tooth material from the Iron Age cemetery at Bjärby in Kastlösa parish on the island of Öland have been analysed for stable carbon and nitrogen isotopes. 21 individuals were sampled. Where possible 4 samples were taken from each individual, from the first, second and third molar respectively and from one compact bone. By doing so it is possible, at least in theory, to trace intra-individual diets throughout life. In total, 64 samples were analysed by isotope ratio mass spectrometer. The low [delta]13C values indicate a diet based mostly on terrestrial resources, while the high [delta]15N values indicate some significant marine input. This discrepancy may be explained by an intake of freshwater fish or meat from suckling animals. The isotope values do not indicate any significant dietary reliance on cereals. Some gender differences in diet were observed. The [delta]15N values of the women were higher than those of the men, indicating a higher tropic level throughout life. The third molar [delta]13C values of the men were higher than those of the women, indicating a somewhat more substantial marine input during the teenage years.
