"Like a lot of liberals back then, Mrs. Raymond believed that the act of eating entailed important moral choices. Lunch was never just lunch; it was a statement about your values. Mrs. Raymond talked a lot about food. Some foods were virtuous (sprouts and tofu), while others were irredeemably sinful (sugary breakfast cereals). Nothing was more unethical than white bread, which Mrs. Raymond described as the product of ruling-class oppression. Medieval lords could afford to have the bran milled from their grain, while the peasants made due with hearty brown loaves. But in the end the joke was on the lords. With no nutrition in their bread, they died earlier than their macrobiotic serfs. Was any of this true? I have no idea, but it made for a memorable parable. To this day, the sight of Wonder Bread makes me anxious."
