From 2006 to 2010, public elementary schools in the U.S. increased the healthiness of their food environments by 3 points on a scale of zero to 100, while private schools saw a 5-point improvement, according to research from the University of Illinois in Chicago. The report in the Journal of the Academy of Nutrition and Dietetics found that public schools added restrictions on fundraisers, signed fewer vendor contracts for sugar-sweetened drinks and offered more whole grains, while more public and private schools offered only lower-fat milk and grew more school gardens.
