Raquel Hernando, a Juan de la Cierva researcher associated with the European project TIED2TEETH, at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), is the lead author of a paper published in the American Journal of Biological Anthropology, in which the teeth of 84 adult individuals found at eight sites in the northeast Iberian Peninsula were analyzed to offer new perspectives on the diet of these populations in recent prehistory.

This study shows that the mixed diet of the agropastoral groups of this period, which covers from the Middle Neolithic to the Middle Bronze Age, was made up of cereals with regular intake of meat or dairy products, though each group had its own dietary specialization.
