In Skyrim: The Elder Scrolls, when your character is low on health, the way to restore it (without using potions) is to eat food.
It kind of seemed strange to me that during a battle, ones character could basically eat a completely unrealistic amount of food to bring their health back up. In one battle, I recall my character eating 38 apples, 12 pies and eight complete wheels of cheese.
Even then, there are no attacks based on the results of eating that much food. There should be, like a belch attack which stuns the enemy or being able to crop dust (ie. fart) the dungeon and use a fire spell to light the place up.
