Rest Limitation

I came to interesting idea .. as far as i saw there is no real use for food as it is .. bread has on use effect but does nothing. What if to rest in wilderness you would need food that would get consumed? And Maybe Better Food would even give you some till next rest bonuses (Something small like +1AB or 1 HP regen/minute etc) so food crafting would be more then just RP tool
And Also i Would limit resting by some time limit in dangerous locations and forbid resting all together in some places. It makes caster very powerfull as they can literaly burn out everything and just rest to go on.

Just further expanding the idea. Such limitation should be enforced on lvl 5 or 6 so low lvls can get used to world and earn some cash before in need of buying items to survive. Also Resting at inn should always be limitless (time and food)
