Michael Pollan’s Food Rules are a great exploration into the sets of personal codes we set up for ourselves to guide and govern our relationship and behaviours with food. They represent ethics of our grandparents, hint at cultural values and traditions, and confer plain and simple common sense. For example:
#19 If it came from a plant, eat it; if it was made in a plant, don’t.
#36 Don’t eat breakfast cereals that change the color of the milk.
