Will the Body of People in Hell, or Heaven, Need to Eat and Drink?

The church hasn't given a definitive ruling on when people get their guardian angels. One of the things that would suggest we won't need to eat and drink, at least the saved, or really anybody, is the fact we're going to be immortal in these physical forms. The image of a feast with god can be a sign of rejoicing and spiritual communion with god even if food isn't literally involved.
