Yes, but it was not free as others have suggested. The card let you buy a certain amount of those goods at a subsidized rate, meant to ease the effects of people hoarding. Vegetables aren't included because the general idea was that people would grow a lot of their own, and demand in the state stores wouldn't exceed supply. Things like meat were harder to come by, so you had ration cards to buy a reasonable amount at a controlled price, and then hope you could have money to buy extra (if it was available).
