Yes...ish. Naturally, what I eat and drink is Essence -- the energy which powers my existence and abilities -- drawn from the aspects of nature that I represent. But when I've materialized, I can eat and drink anything you'd expect me to be able to eat or drink. Though obviously, when I'm not materialized, I can't do any of that because I'm not physical at that point.

I can also create life with others, yes, although the results are ... a bit unpredictable.
