What’s good for your body also turns out to be good for the environment. Substitute chicken, fish, or vegetables for red meat and dairy just one day a week, and your family of four will eliminate the greenhouse gases produced by a 760-mile car trip, say researchers from Carnegie Mellon University in Pittsburgh, who studied the impact of dozens of foods. Other ways to do your part:
Buy local and fresh. Local isn’t better if the food is stored for long periods, using up more energy. Fresh-picked fare not only avoids long trips in fume-spewing trucks, planes, and boats, but it also packs more nutrients and requires no preservatives.
Choose sun-ripened fruits and vegetables. They generate fewer emissions than produce raised in heated greenhouses. Find out what’s in season in your area at nrdc.org.
Cut back on processed foods. A lot of mileage goes into foods with artificial sweeteners, additives, and preservatives because these ingredients are often shipped to the manufacturer from other locations. •
