Eat a wide variety of species.

For many of us, eating has surprisingly little to do with hunger. We eat out of boredom, for entertainment, to comfort or reward ourselves. Try to be aware of why you're eating, and ask yourself if you're really hungry - before you eat and then again along the way.

Shop the peripheries of the supermarket; stay out of the middle.

We spend our lives in front of screens, and cooking is one of the best antidotes.

Don't eat anything that won't eventually rot.
