The study of the human diet in Palaeolithic times is currently among the research areas generating the greatest advances in knowledge. Analysis of the Palaeolithic diet is conducted mainly on the basis of stable isotopes of carbon and nitrogen, which are present in the collagen of human bones. These isotopes indicate the types of food consumed by the individual in the years leading up to their death.
Researchers from the University of Granada (UGR) have analyzed the diets of past peoples from samples in the anthropological collections of the Megalithic necropolises of Panoria (Darro, Granada) and El Barranquete (Nijar, Almeria). They find that although Megalithic communities did vary their eating habits over time, there were no relevant social differences, either in the type of food or in the proportion of proteins consumed.
