TL;DR

Human evolution includes carnivorousness, yet preindustrial societies had limited meat intake, and rising meat consumption marks the dietary transition accompanying economic modernization. Meat is now the largest source of high‑quality animal proteins, with some countries exceeding 100 kg per capita annually, but high red‑meat and poultry intakes bring agronomic, economic, nutritional, and environmental drawbacks that can largely be mitigated by reducing excessive consumption and improving feed production and animal feeding.

Abstract

Carnivorousness is a part of human evolutionary heritage, but typical meat intakes were limited in virtually all preindustrial societies. Rising meat consumption has been a key marker of the universal dietary transition that has accompanied economic modernization. Meat is now the largest source of high‐quality animal proteins, and in some countries its annual supply is as high as 100 kg or more per capita. At the same time, high average intakes of red meat and poultry have had a number of undesirable agronomic, economic, nutritional, and environmental consequences. Fortunately, most of these negative effects can be alleviated by reducing excessively high meat consumption and by managing better both the production of feeds and the feeding of animals.
