With this command, if there is something edible in your inventory, you can eat it.
eat <food item>
eat <food item> #
If you just type "eat food", it will ignore the meal-type food items and attempt to find a piece of food for you to eat in your inventory or your first food pouch. If you only have meals in your inventory, you will be told that you cannot find an acceptable food item to consume.
