I don't see how.  Rather, it might say that against the backdrop of a diet
rich in fresh fruits and vegetables and lots of exersize, foreign proteins
from unprocessed grains and dairy (healthier forms) may be much less of an
issue, to the point that healthy life free from diseases of civilization is
the norm.  Even so, you could also argue that these people might be a little
bit healthier if they were able to replace grains and dairy with fresh meat.
I don't want to open up this same old can of worms again, but my guess is
that, barring religious taboo, grains and dairy are the chief protein
sources in this type of diet because meat is scarce.
