[article] More healthy food lands at U.S. airports. That's especially good news for the 100 million, often hungry, travelers expected to traipse through the passenger terminals during the coming holiday season. According to a survey performed by the Physicians Committee for Responsible Medicine, 76% of restaurants in 18 of the nation's busiest airports offer "at least one cholesterol-free, plant-based entrée" such as green salads, veggie wraps or black bean burgers. In 2001 only 57% of the total eateries at all the airports reviewed served such healthy fare. The best hub to grab nutritious grub: Denver International Airport. The facility tops the 2013 good-for-you food chart as 86% of its eateries serve a nutritious option. In the bad food days of 2001, the Mile-High City's airport received a near-failing grade of 61%.
