Cookies can be eaten on the run

This can save you in many situation when you're harassed by mobs. Instead of standing still in order to eat a nutritious steak or golden carrot (and expose yourself and die), you instead eat like ten cookies while you run away and save your own life. That's how it works in real life: you need some time to eat meat, but cookies can be instantly eaten one by one. This would make cookies more useful and improve food variation without giving potion effects to standard food items.
