According to the great Michael Pollan we should only eat foods that eventually rot. To elaborate – food processing began as a way to extend the shelf life of food by protecting it from fungi, bacteria, insects and rodents. The more processed a food is, the longer the shelf life, and the less nutritious it becomes. Real food is alive and will eventually die! So, how can you bring this new knowledge into the grocery store? Try shopping the peripheries of the supermarket.
