Event presented by Cooking Light during PHA's Building A Healthier Future Summit in Washington, D.C.WASHINGTON, Feb. 6, 2013 /PRNewswire-USNewswire/ -- The Partnership for a Healthier America (PHA), which works with honorary chair First Lady Michelle Obama and the private sector to end the childhood obesity crisis, today announced the return of its annual cook-off at the Building a Healthier Future Summit, held March 6 to 8, 2013, in Washington, D.C. This year, the Great American School Lunch Challenge, presented by Cooking Light, will task two teams, made up of award-winning chefs and school nutrition professionals, with creating the most delicious school lunch, while adhering to a strict budget and nutritional guidelines. "Last year's Great American Family Dinner Challenge was one of the highlights of the Building a Healthier Future Summit. This year's Great American School Lunch Challenge, presented by Cooking Light, will be just as exciting for attendees, who can watch, taste and compare the food they are eating with what was on their tray in their school days," says PHA President and CEO Lawrence A. Soler. "It's also a great opportunity to raise awareness for the higher nutrition standards that school cafeterias nationwide have adopted to encourage healthier habits among K-12 students." Every day, more than 31 million children participate in the National School Lunch Program, and for many, the choices they're offered in the cafeteria line are a substantial part of their daily calories. For other students, what's served at school may be the only food they can depend on. In 2010, the U.S. Department of Agriculture successfully revised the school meal standards for the first time in 15 years with the passage of the Healthy Hunger-Free Kids Act. The competitors participating in the Great American School Lunch challenge will adhere to these updated guidelines and show us just how far a school lunch can go.
