CAZAR Y RECOLECTAR: APORTES INTERDISCIPLINARIOS PARA PENSAR LA NUTRICIÓN EN ESTUDIOS ARQUEOLÓGICOS.

It is discussed the macronutrient characterization of diets consumed by diverse hunter-gatherer groups from southern Patagonia during the Late Holocene. Stable isotope analyses on human bones from Beagle Channel, combined with Bayesian mixing models, detect a high protein intake, more than what health agencies recommend. In the second case it is performed stable isotopes analyses and chemical characterization of adhered and absorbed organic residues to ceramic containers from the central-west of Santa Cruz. Results suggest guanaco was processed and/or cooked in the ceramics used by these groups, with very low visibilty of vegetable processing. Although some studies warn about the health risks linked to these high-protein diets, these case studies exemplify the adaptive flexibility of human organism, to diverse foodways in their nutritional composition.
