Want a way to get kids to choose healthier food? Make it look good and easy to grab, say researchers at Cornell University. Their study, published Friday in the Journal of Pediatrics, suggests that kids are more likely to choose healthy food if the presentation is appealing and it is within reach.

In 2012, the US Department of Agriculture required schools to substitute unhealthy foods with nutritious options, but that hasn’t guaranteed that students eat healthier. “We believe that when children take foods of their own volition, they’re more likely to eat them,” said Andrew Hanks, a research fellow at Cornell University and lead author of the study.
