From all the history I have read of civilisation, it's been grain that has been the foundation of human society as we know it, meat couldn't get us anywhere.

Meat eating among the poor in European societies and derived societies is a new phenomenon at least in the idea that every meal has meat in it.

Take a look outside of Europe or even within less wealthy areas of Europe and their diets are magnitudes lower in their meat consumption.

I've read the opposite re: inflammatory side effects of meat that we are discovering. WHO a few years ago put eating sulfite infested meat as being carcinogenic.
