Aside from that, the amount of food that "Create Food" restores is pretty small per cast (since it was nerfed the last time) and "Restoration" is for one thing, a level 10 prayer, hard to find in stores, and takes over 100 grace to cast, granted that you manage to learn it when you buy it.
Also, the amount of food that each piece of food restores was reduced drastically the last time new food items (the cooking ones) were introduced. Remember when T-rex legs used to restore 450 food? Doesn't happen anymore.
I think the hunger system is fine as it is.
