Oral health and the postcontact adaptive transition: A contextual reconstruction of diet in Mórrope, Peru.

Abstract：

:This work explores the effects of European contact on Andean foodways in the Lambayeque Valley Complex, north coast Peru. We test the hypothesis that Spanish colonization negatively impacted indigenous diet. Diachronic relationships of oral health were examined from the dentitions of 203 late-pre-Hispanic and 175 colonial-period Mochica individuals from Mórrope, Lambayeque, to include observations of dental caries, antemortem tooth loss, alveolar inflammation, dental calculus, periodontitis, and dental wear. G-tests and odds ratio analyses across six age classes indicate a range of statistically significant postcontact increases in dental caries, antemortem tooth loss, and dental calculus prevalence. These findings are associated with ethnohistoric contexts that point to colonial-era economic reorganization which restricted access to multiple traditional food sources. We infer that oral health changes reflect creative Mochica cultural adjustments to dietary shortfalls through the consumption of a greater proportion of dietary carbohydrates. Simultaneously, independent skeletal indicators of biological stress suggest that these adjustments bore a cost in increased nutritional stress. Oral health appears to have been systematically worse among colonial women. We rule out an underlying biological cause (female fertility variation) and suggest that the establishment of European gender ideologies and divisions of labor possibly exposed colonial Mochica women to a more cariogenic diet. Overall, dietary change in Mórrope appears shaped by local responses to a convergence of colonial Spanish economic agendas, landscape transformation, and social changes during the postcontact transition in northern Peru. These findings also further the understandings of dietary and biocultural histories of the Western Hemisphere.
