Yep, there's a way to throw out unwanted food/items. To do this, go to the book icon on your Tama (the 9th icon) . Then, go down to present. Click on either 'Food' or 'Item', and choose which piece of food or which item you want to get rid of. It will then say 'Wrap?', but you don't want to wrap it so press the A button and it will say 'Trash?'. Press the B button when it says that and it will ask you if you're sure. Say 'Yes' if you really are! .
