Food Miles
I
spent some time yesterday afternoon, hanging out in the kitchen of a local restaurant where I've become a friend of the chef. He seemed pleased, as he was pushing out salads and watching the Pittsburg Steelers, with the quality of a crate of tomatoes he had just gotten on Friday. But when I asked where they came from, he knew I wasn't asking about his wholesale supplier. "California," he muttered. He knows how I feel about local produce and in-season foods.So it was an interesting coincidence to see this thought provoking piece that came across one of the food news feeds a few moments ago. It's a subject near and dear to my heart, although I've never quite expressed the concept the way the author has: Food miles.
No, food miles are not redeemable for free food; nor can they provide upgrades from, say, California plum tomatoes to San Marzano tomatoes. In fact, as units of measure go, fewer are better.
Food miles are, as the phrase suggests, the number of miles a foodstuff needs to travel to get from its point of origin to your dinner table. Often, food miles are used as a measure of volume rather than distance. That is to say, in gallons of diesel, or jet gas.
On the surface, some shoppers might look at this as a noble endeavor. With more and more mainstream grocery stores offering organic produce, they may overlook the fact that those gorgeous, organic yellow bell peppers needed to travel 3,000 miles, because they came from a highly reputable, certified organic farm in Salinas Valley, California. Or perhaps they came from a fair trade cooperative somewhere in the Andes. But then there's that doggone gas.
Barbara Kingsolver, one of my favorite authors, made me aware of the concept of factoring the cost of gas into the cost of food in her collection of essays, Small Wonder. (Harper Collins, 2002.) Since then, I've become more thoughtful—some of my friends might use stronger terms—about seasonal, and local foods. She's taken the concept a step further (to the frustration of her publisher) by being very selective about which speaking engagements she accepts based on how much jet gas it will take to get her to and from her destination.
Western Europeans, of course, have known about food miles since they discovered food. Nothing edible travels too far in Europe; often no further than the garden outside the kitchen door. You're not likely to find gorgeous, organic yellow bell peppers in the Campo dei Fiore in December, because nobody in the vicinity of Rome is growing them in December.
In the past, I've been as guilty as anyone, simply because it was great to be able to cook traditionally summer dishes, in February. It wasn't so long ago that I thought Bread & Circus (now Whole Foods) was about the best thing that ever happened to grocery shopping. Under Barbara Kingsolver's tutelage, though, I got even further back to my roots, and discovered the reason why God had invented Mason jars.
But the only surprise for me in all of this, is that it's happening now. The whole phenomenon of eating any food at any time of the year began in the thirties (I believe) with The Great American Lettuce Train. I'm a little shaky on the details, but it seems it was a regularly scheduled cross-country train that originated in Stockton, California, where it collected boxcars full of iceberg lettuce, carrots, celery, onions, and whatever else was fresh and in season there. Thirty-six hours later, the train arrived at Penn Station in Manhattan. I believe the whole notion of the Great American Lettuce Train came about so the patrons at the Waldorf-Astoria could dine on iceberg lettuce wedges with Russian dressing any time of the year. So if we're seeking to lay blame on anyone, we have a vast array of choices that go back three or four generations. And those trains ran on coal.
I've been preaching "Think global, eat local," for three or four years now. Clearly, Barbara Kingsolver has been preaching it longer. I hope the notion catches on. I'm concerned that the food conglomerates' marketing message of 'Look ma, now we're organic!' will obfuscate the added cost of jet gas, and the amount of CO2 in the atmosphere, to put organic vegetables on your dinner table.
I believe it was Jaques Pépin (who lives in Connecticut) who said—and I'm paraphrasing—I'd prefer a tomato I've just picked from my neighbor across the street over the finest organic California tomato when they're in-season together. He seems to get it about the gas.
