Behavioral economics is the meeting of two models: 1) behavior models in psychology, coupled with 2) the decision making models in economics, according to Cornell University researchers Brian Wansink, Ph.D. and David Just, Ph.D. It highlights how your present biases in the perception, memory, or thoughts, in this case, about the consumption of produce, may influence your decision or choice to consume them. Researchers are now using behavioral economics to make low cost, subtle changes in the display and location of healthier foods in school cafeterias, which have been shown to increase the consumption of these healthier foods.
For example, a study published last week in the Journal of the American Medical Association (JAMA) uncovered that when it comes to getting kids to eat veggies at school, a picture may speak louder than words. Researchers at the University of Minnesota discovered that putting pictures of carrots and green beans on each cafeteria tray in the lunchroom of a local elementary school (see above), changed the behavior of the kiddies and increased the likelihood that they would choose to put these veggies on their trays. Consequently, the researchers found an overall significant increase in the veggies consumption among the group when they were given the tray with the pictures compared to another day when carrots and green beans were served but there weren’t any “picture reminders” on the cafeteria tray. This is behavioral economics in action.
This isn’t the first study using behavioral economics. Wansink and Just have conducted numerous studies in school lunchrooms with fascinating results. Their research has shown that simply relocating healthy foods on the cafeteria line can increase their selections. As any good real estate salesperson will tell you, when it comes to selling, it’s all about location, location, location:
In addition to switching the location of fruit, Wansink and Just also uncovered that by giving carrots a “cool” name, kids were more apt to not only pile them on their plates but also eat them:

On the home front, you may want to find a decorative bowl, fill it with bright red apples or oranges, and make it the new centerpiece for your kitchen table. When it comes to healthy eating, think "location, location, location."
