DENVER (AP) -- There will be more whole grains on school lunch menus this year, along with a wider selection of fruits and vegetables and other healthy options. The challenge is getting children to eat them. "We don't want healthy trash cans. We want kids who are eating this stuff," said Kern Halls, a former Disney World restaurant manager who now works in school nutrition at Orange County Public Schools in Florida. At a School Nutrition Association conference in Denver this summer, food workers heard tips about how to get children to make healthy food choices in the cafeteria.
