Eat real food. Products full of trans fats, high-fructose corn syrup, and multisyllabic additives take enormous energy to create. Choose energy-efficient items: fresh, whole foods with minimal or no packaging.
Enjoy meatless meals. Cut out the cheeseburgers entirely, or just cut back: Go meatless at least once a week. And, if you choose to eat meat and dairy, go for organic options from small-scale family farms.
Live la vida local. Minimize your “foodprint” by buying from locally stocked supermarkets and farmers' markets. Get personal with your produce by becoming a member of a community-supported agriculture program (csacenter.org) or by visiting a U-pick farm (localharvest.org).
