One important factor is that many foods were eaten only occasionally.
Peanuts would never have been a staple. Cultivation and continuous
consumption probably causes problems. A toxin taken occasionally is
different then continuous exposure.

Yes, and that's why I think the "naked with a sharp stick" rule is a simple
starting point, rather than a final conclusion. Individual experimentation
and research may be needed beyond it for at least some, which I have found
to the case in my experience. So just because peanuts and groundnuts could
be eaten raw (or relatively raw, in sun-dried form) does not necessarily
mean they are going to be optimally healthy for all. 

Plus, some plants are occasionally consumed in HG societies that are known
to be toxic, for medicinal (including possibly for hormetic effects) or
spiritual/shamanic/ecstatic purposes. So even toxic foods may have some
benefit in some contexts.
