““Approximately eight hundred skeletons from the Dickson Mounds in the lower Illinois Valley have been analyzed. They reveal a clear picture of the health changes that accompanied the shift from foraging to corn farming around 1200 AD. Archaeologist George Armelagos and his colleagues reported that the farmers’ remains show a 50 percent increase in chronic malnutrition, and three times the incidence of infectious diseases (indicated by bone lesions) compared with the foragers who preceded them. Furthermore, they found evidence of increased infant mortality, delayed skeletal growth in adults, and a fourfold increase in porotic hyperostosis, indicating iron-deficiency anemia in more than half the population.””
