It’s official: Americans are eating more fresh foods than they did five years ago. A recent survey of 800 U.S. adults by the W.K. Kellogg Foundation reports that more than 68 percent of respondents say they eat more whole grains, fruits and vegetables than they did in 2007. Farmers’ markets and stands have attracted 70 percent of the survey participants, although only 14 percent regularly shop at such venues. More good news: 64 percent of the respondents agree that it’s very important that produce be grown in an environmentally friendly way and also important that the fruits and veggies be organic.
