Dwarf Fortress AM has no food (last time I played anyway).
I can't confirm or deny that for sure, but the wiki says the following:
"Pressing T will let you see a very zoomed out map of the surrounding area. Moving about on this map is much faster, as well as it heals your adventurer, keeps him from starving, dehydrating, or getting tired."
So I guess food has some role in AM, though I don't play it enough to really know.
