The goalposts have been the same for years as this is long recognized. It's even mentioned in that study that you quoted, as pointed out by
@Andrei79 . The original document references the issue.
Separately, it's also known that people following the paleo diet are on average healthier. That doesn't mean that the paleo diet is perfect, but it is usually done by upper-middle class white people, and it removes a few awful foods.
The populations of Okinawa, Iceland, and Pioppi all consume animal products, and are known internationally for living exceptionally healthy lives, living to older ages, etc. Historically, it was alleged that the people of Okinawa were vegans/vegetarians, but that turned out to be fake news. They have historically consumed substantial quantities of pork fat, lamb, and sea life.
I suspect that you understand all of this and you're just holding on because you like to believe.
