FILE - In this Feb. 10, 2012 file, photo, first lady Michelle Obama and White House chef Sam Kass, second from left, participate in a Let's Move event with Dallas Cowboys football wide receiver Miles Austin, center, Bravo's series "Top Chef" Head Judge Tom Colicchio and Trey Payton, right, of Nancy Moseley Elementary School, at Kleberg Rylie Recreation Center in Dallas. Kass's job as personal chef to the Obama family is probably the least important part of his portfolio. He is also the White House senior policy adviser for healthy food initiatives. That's put him out front as the first lady presses her campaign against childhood obesity. (AP Photo/Carolyn Kaster, File)
