I'm not sure what the last part of your statement
means. Do you mean that they would have been poisoned
by eating the wrong leaves/stems, or that they would
not have been able to eat a large enough quantity of
leaves/stems to sustain life?

I think they started eating leaves/stems because they
liked them (as in tastes good). Human beings are
naturally curious, and I'm sure they tasted just about
anything they could get their hands on.
