He does eat and drink; while he is in his special pressurized chamber, he can remove his helmet and consume food normally, but otherwise, he consumes nutrient-rich much through his mask, which is equipped for such action.

Even outside his pressurized chamber, he can survive for short periods of time without his mask, as has been shown canonically in Star Wars: Rebels, and even in the original trilogy (remember that the pressurized chamber was open when the Admiral Piett walked in to give his report in Empire Strikes Back?).
