604 Delayed Vending Machines Encourage Healthier Snack Choices, Study Finds

If cookies, chips, and other high-calorie snacks take longer to fall from the vending machine, you may be enticed to get a healthier snack instead, according to a new study funded by the National Institutes of Health.

The researchers created experimental vending machines that had a 25-second time delay before high-calorie snack options were released. Consumers were made aware of the delay by signs on the machines and a touchscreen menu with a countdown timer.

“Having to wait for something makes it less desirable,” Brad Appelhans, lead investigator of the study, said in a press release. “Research shows that humans strongly prefer immediate gratification, and this preference influences choices and behavior in daily life.”

The delay made some people rethink their snack choices. There was a 2-5 percent increase in the proportion of total healthy snack purchases.
