We don't have guts developed to cope with lots of meat. We have guts developed to cope with some meat. Our ancestors found meat harder to get than nutritious roots, nuts, berries and the like, so meat was not the be all and end all of their diet. It was just a part of it. If you look at the diet of English agricultural workers around 1900, they ate small portions of meat accompanied by huge quantities of cereals and vegetables. Even for people who worked in the production of food, meat was a luxury item occupying a corner of the plate. Having meat dominating a plate is a thing that has only really happened since World War Two, and it isn't healthy if done day after day.Jdsk wrote: ↑12 Oct 2021, 8:04amHumans have been eating meat for more than 2M years, and before H sapiens existed. This might have played a major rôle in the development of the modern human brain.
Our guts look appropriate for the task.
Excluding meat from the diet carries some nutritional risks, although we know how to manage them.
And although it's interesting the evolutionary history isn't particularly relevant to current effects on health. And the arguments from ethics and environmental impact stand on their own merits.

I'm not making a case for being vegetarian or vegan, but for people having a good healthy balance to their diet. And it helps if people recognise that the total dominance of meat on the plate is a relatively modern thing.
