Goodberry is actualy interesting example ... To eat some fruit that was forced to grow by Druid (or at least that is how i allways imagined it ... but i presume its possible to also think that Druids simply "created" the berry out of thin air)
Goodberries are berries enchanted by a Druid to be magically filling, and heal a single hp.
The mere existence of that spells strengthens the argument that food shouldn't heal up. Why waste a spell slot on casting Goodberry when you can just eat a normal carrot?
