Eating meat: Constants and changes
نویسنده
چکیده
Eating meat has been an important component of human evolution and rising meat consumption has made a major contribution to improved nutrition. Expanding the current practices of meat production would worsen its already considerable environmental consequences but more environmentally sensitive ways of meat production are possible. Although they could not match the current levels of meat supply, they could provide nutritionally adequate levels worldwide. This would mean a break with historical trends but such a shift is already underway in many affluent countries and demographic and economic factors are likely to strengthen it in decades ahead. & 2014 Elsevier B.V.

Evidence is presented showing that the luteal phase is ma...
