In the tabletop, each berry produced by the Goodberry spell restores 1 HP and provides enough nourishment for 1 day. The flavor text for the spell in game says nothing about it acting as a ration or providing nourishment. Is this a bug or a design decision? If it's a design decision, I'd argue against it. The strength of Goodberry is, in part, its ability to provide rations for the cost of a 1st level spell slot.
