I consider Gish totally untrustworthy, even on something that appears
relevant to his expertise in biochemistry (although I suspect that the
question of what molecules we could digest has more to do with
physiology than biochemistry).

Any experts who could enlighten us? How do we 'use' the food we eat?
Do we use large complex molecules as building blocks (that would imply
that our foods would have to use very similar chemical mechanisms to
ours) or not?
