I have my doubts as to the validity of this explanation.  Might not
the contents of their diet been built around the fact they were flesh
eaters.  Not all the tribes in NG were man eaters at the time they
were "discovered".  Although from my readings most races indulged in
the practice at some stage it seems to have been something that they
tended to grow out of as their technology/development progressed.
