Is the narration true that Umar ibn al-Khattab prohibited his family from [eating] sweets?

The circulating story about Umar ibn al-Khattab preventing his wife from saving sweets and returning her money to the public treasury has no basis. The correct account is that Umar (may Allah be pleased with him) refrained from eating sweets out of piety, because he saw that they were not accessible to all Muslims.
