Michael Pollan has an article and fun slideshow at the New York Times about his favorite “food rules” he received from his readers. They range from the purely funny to the quite thoughtful. I think if I have a food rule, it comes from a long-ago boyfriend. He would do things like order and eat a cheese quesadilla, but then lament for an hour afterward about how bad it was for him and how he shouldn’t have eaten it. So that’s my rule: “If you’ve already eaten it, don’t beat yourself up over it. Just enjoy it and move on.” What’s yours? –Mary T.
