Apollo suits had a "food/drink port" but it was [apparently never used][1].  The [main purpose of the port][2] was to allow the crew to eat and drink in a contingency situation where the vehicle was depressurized and they had to survive in the suits for an extended period of time.

> In  case of  complete  loss of cabin  pressure during  a  mission, 
> the crewmen  might  be  required  to wear  pressurized  suits  continuously for as  long as  115  hours.  Water  would  be available  by
> passing the  probe  of  the potable-water  dispenser  through  the
> hel­met feedport.
