The Maasai are also known to eat a lot of meat and dairy.
But, humans have been eating unsaturated fat from nuts, seeds, and meat for millennia. Unsaturated fat is not the devil. We have very strong evidence that a diet high in meat, particularly farmed red meat, is both carcinogenic and causes heart disease. When you look at high processed diets across the globe today, you'll notice they have similarities:
1. Extreme consumption of fatty, farmed meats
2. Very little fruits, vegetables, nuts, and other foods high in fiber
3. Processed shelf-stable goods
4. Extreme portion sizes
When people look at the Mediterranean diet, it's not just that they eat much more food high in unsaturated fat as opposed to saturated fat. They also eat less and move much more.
Incorrect, your points are otherwise true. Inuit diet was close to 100% animal products, way more than anyone but carnivore diet people today eat.
Most Americans are obese, so we’re already eating way more than the intuit. Probably 1000+ calories more a day.
And then, Americans eat multiple servings of meat with every meal.
I agree that the fact that this meat and fat is wild may be the root cause of the differences between their and our health outcomes. That indicates, though, that we may have something in our forms of meat and dairy that potentially harms us - and that if we identify what, we may be able to get rid of that specific problem.
It's been pretty much accepted that out ancestors (a long time ago) were scavengers, then became farmers/Livestock farmers and then industrialization.
It's only with the latest that we did start to produce meat in large quantity.
