FILE - In this Oct. 20, 2010, file photo Assistant White House Chef Sam Kass weighs sweet potatoes as he works with first lady Michelle Obama and students on the White House Kitchen Garden Fall Harvest on the South Lawn of the White House in Washington. Kass's job as personal chef to the Obama family is probably the least important part of his portfolio. He also is 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/Charles Dharapak, File) less
