  What about water and salt? Where did the Torah permit those to be
  consumed?

  CM responds:
  I think the most straight forward approach would be a kal vechomer from the permit to eat vegetation. Since  man was granted permission to eat vegetation, then certainly that would include any substances that are indeed consumed by the vegetation in order for them to grow and thus become food for man.
  I should point out that this was not quite as obvious as I originally imagined. Water is pretty clear but I had to google around a bit before I found that plants do need chlorine (as in sodium chloride) in small quantity to enable cellular metabolism. Just a cursory search turns up that salt can be harmful to most plant life. Anybody familiar with  the details of the need (all be it small) for chlorine for cellular metabolism in plant life?
R’nLL responded:
That's irrelevant.  No human being was aware of any need for salt, and therefore could not have deduced by kal v'chomer that salt is permissible.  Salt is permissible for a very simple reason.  It was never forbidden.

CM responds:
Do you really have any idea of what Adam Harishon knew or did not know?
