ITHACA, N.Y., May 4 (UPI) -- Ordering a school lunch in advance increases the odds elementary school students will choose a healthy entree, U.S. researchers suggest.
Andrew S. Hanks, a postdoctoral researcher at the Cornell Center for Behavioral Economics in Child Nutrition Programs, said in two upstate New York elementary schools, students used an electronic pre-ordering system to order lunch in the morning. Fourteen teachers agreed to enroll their classes in a four-week study to test the effects of pre-ordering lunch.
