The comparisons to making totems, potions, poisons, etc. by game time is rather rediculous, imo.
Everyone uses food/drink, 24x7 that they play - unless they specifically turn off autoconsume. I would place money that the vast majority of people do not turn off their consumption while they're milling about.
Not everyone uses potions/poisons. Not everyone uses arrows. Those are specialist scenarios.
Food is universal. Everyone needs it. It's not a scout thing (poisons), it's not a ranger thing (arrows), it's an everyone thing. Punishing the creators by yielding 2 at a time at this point in the game is not fun.
I'm to the point of agreeing with Feldon since the "community" is so hard-headed to disallow a small change. Eliminate the Provisioner class and have chef NPCs that sell this stuff at fair value (75g a stack @ 90).
