Then we actually don’t know whether paleo diets resemble what our distant ancestors likely ate, do we?
I suppose they may be similar by coincidence.
And yes, I agree that game meat and wild tubers are quite different from pork chops and supermarket sweet potatoes. I am not sure why this is relevant, though. Ignoring agriculture is pretty much impossible for most people and, in any case, we are mostly talking about the right direction to shift your diet in, not about exact matches.
The point is that the shifts suggested by the paleo dieters aren’t necessarily in the direction of truly ancestral diets. For instance, paleo dieters often suggest to reduce the intake of calories from starches and increase calories from meat, because paleolithic people supposedly ate that way. Setting aside the obvious naturalistic fallacy, it’s not actually clear (and it can be quite well false) that paleolithic people normally consumed less starches and more meat than the typical Western pattern diet (or the Mediterranean diet, or other “healthy” variations of the Western pattern diet).
EDIT:
To expand they previous point, it seems that mainstream nutritionists and paleo dieters both agree that the Western pattern diet is not very healthy. Both suggest to reduce sugars, salt, alcohol, caffeine and processed foods. The difference is that mainstream nutritionists suggest to reduce meat and dairy, while paleo dieters suggest to reduce starchy foods. Paleo dieters can’t really support their non-mainstream suggestions with evidence of ancestral dietary patterns.
The point is that the shifts suggested by the paleo dieters aren’t necessarily in the direction of truly ancestral diets.
First, as we agreed, there were many different “truly ancestral” diets. Second, it depends on the starting point. I will assert that if you start with a typical American diet, eating most any kind of paleo will shift you in the right direction. We can argue about starches and such, but it’s pretty clear that no one ate large quantities of grains or seed oils 100kya, not to mention all the processed food-like substances :-/

Agreed.
