In Oblivion, I always thought it was annoying that the vast majority of food only restored fatigue. I never found myself eating it to help out with anything. Even if it just restored a tiny bit of health, that would be worth it. Same thing for making potions. I ended up making like 300 restore fatigue potions.
I know it's probably a balance thing - if they restored health, anyone could make a restore health potion out of almost anything.
In Skyrim, is it the same?
