#15 Get out of the supermarket whenever you can.
You won't find any high-fructose corn syrup at the farmers' market. You also won't find any elaborately processed food products, any packages with long lists of unpronounceable ingredients or dubious health claims, anything microwaveable, or perhaps best of all, any old foods from far away. What you will find are fresh, whole foods harvested at the peak of their taste and nutritional quality-precisely the kind your great-grandmother, or even your neolithic ancestors, would easily recognize as food. The kind that is alive and eventually will rot. -Michael Pollan, Food Rules
