Junk Food Twice as Likely to Distract as Healthy Food, say Researchers

Kudos to marketers of junk food.  They have created illusions of products that are so alluring that hungry people are twice as likely to be distracted by junk food than natural, healthy food.  According to what new research findings suggest, people have been trained to respond more readily to highly processed, chemical-laden ‘faux food’ rather than natural, whole foods.  Luckily, the researchers also found that after only a few bites, junk food was no more enticing or distracting to people than whole, natural foods.  This leaves hope for people to retrain their brain’s reactions to the manipulative marketing and packaging of junk food when they need to nourish their bodies and brains.  A key factor in this process: Don’t keep junk food in the house.  And, if another household member insists on keeping junk food on hand, at the very least, tuck it away in the pantry, out of sight.

Junk Food Twice as Likely to Distract as Healthy Food

Even when people are hard at work, pictures of cookies, pizza and ice cream can distract them — and these junk food images are almost twice as distracting as health food pictures, concludes a new Johns Hopkins University study, which also found that after a few bites of candy, people found junk food no more interesting than kale.

Study overview

Researchers Dr. Howard Egeth, a professor in the Department of Psychological and Brain Sciences and lead author Dr. Corbin A. Cunningham, Distinguished Science of Learning Fellow in the Department of Psychological and Brain Sciences, created a complicated computer task, in which food was irrelevant, and asked a group of participants to find the answers as quickly as possible. As the participants worked diligently, pictures flashed in the periphery of the screen — visible for only 125 milliseconds, which is too quick for people to fully realize what they just saw. The pictures were a mix of images of high-fat, high-calorie foods, healthy foods, or items that weren’t food.

All of the pictures distracted people from the task, but Cunningham and Egeth found things like doughnuts, potato chips, cheese and candy were about twice as distracting. The healthy food pictures — like carrots, apples and salads — were no more distracting to people than non-foods like bicycles, lava lamps and footballs.

Next, the researchers recreated the experiment, but had a new group of participants eat two fun-sized candy bars before starting the computer work.

The researchers were surprised to find that after eating the chocolate, people were not distracted by the high-fat, high-calorie food images any more than by healthy foods or other pictures…

Cunningham said the results strikingly demonstrate that even when food is entirely irrelevant, and even when people think they’re working hard and concentrating, [junk] food has the power to sneak in and grab our attention — at least until we eat a little of it.
