Yes, I considered this but if there was no physiological/survival pressure
against people with sweet tooths then I wonder why taste sensitivity to
sweetness varies in relation to sweetness in the environment eg my pygmy
example. I don't know if this is widespread but if so I would tend to think
it was a useful adaptation. I could easily be wrong though
