O. I have access thanks to my university subscrption. I'll try to find some time to make a summary of the main points of view but - basically - it is about human needs and meat (based on the pyramid of Maslow). How humans need (or may need) it from a biological point of view but also from a cultural/social point of view. Thought it was relevant for paleo. I'll see what I can do and I'll come back later...

Thanks, Iguana.  I do not know where this cherimoya-kid sees any criticism about meat-eating?? Now really... On the contrary, the study goes clearly against vegan points of view as it advocates that meat eating is part of our common history and is not even close to disappear in the near future. Anyhow, if he feels like banning me, he may do so. As if I'd care. I subscribed to this forum because of my interest in meat and society. Clearly this may not be the right place. How absurd can this get?

Anyway, the forum does not allow me to post external links - but for those interested - try putting this sciencedirect.com/science/article/pii/S0195666315001166 after a www.

Maybe this recent study can be of interest?

Meat traditions: the co-evolution of humans and meat
Appetite - Volume 90, 1 July 2015, Pages 200–211

The debate on the future of meat centres on recent environmental, economical, ethical, and health issues, whereas historical dimensions are all too often overlooked. The fiery discussions are nevertheless affected by an underlying legacy of “meat traditions” and accompanying hunting, slaughtering, eating, and sharing activities, rituals, and rites. Eating meat is a biocultural activity. Therefore, a closer inspection of the evolutionary, collective, and semiotic aspects of meat in human societies is required. This study ventures such an exploration based on a heuristic model inspired by Maslow's pyramid of needs, distinguishing between physiological, security, community, value, and holistic levels. Besides the potential relevance of an innate craving, it is argued that meat has interfered with the development of fundamental human characteristics, both as a physical and conceptual resource. This relates, amongst others, to elements of gender differentiation, cooperation and reciprocity, social stratification and power, religion, cultural expression, and identity. As such, meat traditions provide a basis for evolutionary and long-term social processes, on which more recent and shallow courses of action are superposed, affecting contemporary behaviour. Several research questions were identified to further explore and anticipate the impact of meat on human populations and their societal and economic functioning.
