In the ongoing battle to get children to eat healthfully, parents may do well invoking the names of superheroes to come to their rescue, say Cornell researchers.

Just as Popeye inspired a generation to eat spinach, such role models as Spiderman or Batman could help children make healthy choices, according to Brian Wansink, the John S. Dyson Professor of Marketing and director of the Cornell Food and Brand Lab.

Wansink, with postdoctoral researcher Mitsuru Shimizu and visiting graduate student Guido Camps of Utrecht University in the Netherlands, conducted a study in which 22 children, ages 6-12, at a summer camp were asked if they wanted "apple fries" (thinly sliced raw apples) or French fries during several consecutive Wednesday lunches.

During one of those lunches, the children were first presented with 12 photos of real and fictional role models and asked, "Would this person order apple fries or French fries?"

The researchers hypothesized that children who thought admirable models would eat well would activate positive associations towards healthful food and become more likely to choose apple fries over French fries.

The results supported this theory: 10 (45 percent) of the children selected apple fries after viewing pictures of superheroes and other role models, compared with the two (9 percent) who chose apple fries during other lunches with no prompts. The study was recently published in the journal Pediatric Obesity.

"Fast food patronage is a frequent reality for many children and their parents. Simply instructing a parent to order healthier food for a child is neither empowering for a child nor easy for a parent," Wansink said. "Advising a parent to ask their child 'What would Batman eat?' might be a realistic step to take in what could be a healthier fast-food world.

"On average, children who selected apple fries consumed only 34 calories whereas children who selected French fries consumed 227 calories. That's almost seven times as many calories just from the side dish of the meal," he added. "If you eat fast food once a week, a small switch from French fries to apple fries could save your children almost three pounds of weight a year."
