Changing cultures, changing cuisines: Cultural transitions and dietary change in iron age, roman, and early medieval croatia

摘要

Food is well-known to encode social and cultural values, for example different social groups use different consumption patterns to act as social boundaries. When societies and cultures change, whether through drift, through population replacement or other factors, diet may also alter despite unchanging resource availability within a region. This study investigates the extent to which dietary change coincides with cultural change, to understand the effects of large-scale migrations on the populations' diets. Through stable carbon and nitrogen isotope analysis of Iron Age, Roman, and Early Medieval human bone collagen, we show that in Croatia large-scale cultural change led to significant changes in diet. The isotopic evidence indicates that Iron Age diet consisted of C _3 foodstuffs with no isotopic evidence for the consumption of C _4 or marine resources. With the Roman conquest, marine resources were added to the diet, although C _3 foodstuffs continued to play an important role. In the Early Medieval period, this marine component was lost and varying amounts of C _4 foodstuffs, probably millet, were added to the otherwise C _3 diet. In both of these transitions it is likely that the changes in diet are related to the arrival of a new people into the area. Am J Phys Anthropol 2012.
