I can confirm that a change has happened to food but not all of it, back to what this post first said, for ages I kept using honey as a very powerful food for HP regen while traveling or doing anything, it gives now 20 both, HP & stamina & have 5 HP/tick, I bet on my life that it was 4 HP/tick with all the rest being the same & thus I'm more inclined to believe that a change to food has happened.

What changed occurred to other food beside those mentioned in the post I cannot tell but it would be interesting, they might come with the update patch notes.
