Fruits, vegetables, and whole grains are important sources of nutrients for healthy growth and development of young children. Recent evidence suggests that sack lunches packed by parents for children to consume at child-care centers do not regularly meet the goal of one serving of fruit, vegetables, and whole grains. Lunch Is In The Bag is a child-care center–based nutrition education program targeted at parents of preschool-aged children to increase the number of servings of fruits, vegetables, and whole grains in sack lunches sent from home that was pilot tested in fall 2008.
