I have no problem with you or anyone else adopting your own
criteria, but I just want to point out that you are adding to
what we have generally understood as the basis of paleodiet. In
effect, you are proposing a more restrictive diet.

Well, do we want to say that these foods are "not paleo" or that
they are paleo but not very good for us anyway? Nuts are clearly
paleo, but we have some people here saying that we shouldn't eat
them because they contain anti-nutrients. That is, we know
something about them that paleolithic people didn't know, and
therefore have reason to avoid them. This approach, that modern
scientific knowledge "trumps" the principle of paleolithic
availability, is not unreasonable but I think we should be clear
that it represents a different approach.

If that is correct then we must abandon the premise that paleo
foods are the best foods, right? It means that each paleo food
must be evaluated against our current scientific understanding.

It's true that the date of the first human presence in the
Americas is in dispute. It's also hard to guess how many of
those ancient tomato-eating native Americans are ancestors of
contemporary people. But it's really not important, is it?
Tomatoes didn't become a significant part of the human diet until
after they were taken back to Europe and used, just a few
centuries ago. Even if some people in the Americas were eating
them regularly before that, it wouldn't make much difference if
the premise that we need *hundreds of thousands* of years to
adapt to a food source is correct.
