I didn't mind food ... out of combat, as it was a compensation for the 1 Short Rest (i.e. I do not spam Long Rest).

But eating a Pig Head in combat was a bit too much on many levels. crazy
Anyhow, I agree : *if* food continues to heal, that should be only out of combat.

I did not, though, eat the Dwarf meat (I will destroy it next time I load and give them a funeral).
