When Joanne Morton and Lydia Shaw came across the Boston Public Market, which features only New England businesspersons, they knew they had to stop in. The women, visiting from southeastern Connecticut, always try to buy local. "We always try to support our local farmers and businessmen," says Ms. Shaw. "We're not into big companies," adds Ms. Morton.
They aren't alone. A great number of Americans continue to be attracted by "local" food and to buy it, according to recent surveys from the International Food Information Council Foundation, the Pew Research Center, and British polling firm Ipsos. But what does it mean to shop local? For some, local is still a matter of geography. For others, it is about supporting their local economy (经济). And for still others, it is about knowing where their food comes from and how it is made, even if it is coffee shipped from a Costa Rican company. In 2008, Congress passed a bill that gave money to support local food. According to the Food, Conservation, and Energy Act, a product that can be considered local has to travel less than 400 miles.
But Lydia Zepeda, a professor at the University of Wisconsin-Madison, has found the largest agreement about what is local is any product that comes from within an hour's drive. "But is that with or without traffic?" She asks. "What if it crosses state lines?" adds John Hayes, a food science professor at Pennsylvania State University. "A customer might like to buy local to help an old town," he says. "Or maybe it's just because local food tastes better." It is for Kaitlin Bohon. "I taste a difference," she says at the Boston Public Market. For Ms. Bohon, buying local is both about supporting New England business and knowing who grew and handled her food.
