Long story short on what you wrote - meat is a nutritionally rich food option and kind of nutritionally acceptable if your people have been living in the tundra for a few thousand years & have actually managed to genetically accommodate it, since there isn’t much else food the further you go north (although it’s very much overly simplistic to depict Inuit diets as entirely meat-based). But for modern people, in temperature or tropical regions, it makes no sense at all, plant-based diets give you the best balance of nutrients without extremely high fat and cholesterol content…there’s a real anti-scientific hubris going on with people trying to brush away this basic fact.
