Joshua, I have had that same thought. People say that we should eat
everything in moderation, and that sure sounds like a sensible thing
to do, but what does it mean in practice? Should we eat insects, like
some of the groups that Weston Price studied? Hell no! But why not?
It is culturally determined what is even considered to be part of the
universe of substances we consider food. And even if we could agree
on such a universe of foods, what exactly is moderation? Should I eat
beef once a day, once a week, once a month? I don't know. I suppose
if everyone around me was eating beef daily, then that would seem like
a moderate intake to me. But in actuality, that might not be optimal
for me, based on my body's own nutritional demands.
