yes,
1)go to book icon
2)go down to present and click it
3)go to items or food, whichever you are planning to discard
4)go to that item and click 'A' button
5)it will say wrap, click 'A' button and it will say trash?, click 'B' button and it is trashed
if you want to discard food, just eat it to get rid of it. just a little advice.
