At the beginning of the 1950s many basic goods were still rationed or in short supply.
People did not know that fatty foods could be harmful, and it mattered less because, as food was scarce, it was rarely possible to overeat. Few people were overweight in the 1950s. Dripping on bread and home-made cakes were popular snacks.
Frozen food had not been invented, so although food was fresh in summer, you had to buy tinned or dried foods in winter.
