How much do you know about the science of food and productivity? Just as your car needs fuel, your body does too--if you're not eating the right food, you're negatively impacting how you feel, your physical health, and your capacity to operate successfully throughout the workday.

But, eating right is not always easy. According to the U.S. Centers for Disease Control and Prevention, approximately 40 percent of American adults are obese, which works out to a shocking 93.3 million people.

Plus, overeating and over-snacking at the office is common in any workplace environment or sedentary office lifestyle. Some of us even have a drawer in our desk devoted to snacks of all kinds (I know, because that's how I survived many a long workday.)

It can be difficult to curb unhealthy food, but a new study from the University of Chicago, Booth School of Business gives us insight on how we can battle our own junk food addictions.

According to new research, one way to curb the junk food addictions is to have a "simple and brief intervention" that details the effects of food-marketing campaigns.

The study, "A Values-Alignment Intervention Protects Adolescents from the Effects of Food Marketing," found that when students reframe their perspectives on food-marketing, they can protect themselves from making unhealthy food decisions.

The researchers asked one group of students to read fact-based and exposé-style material about large food companies. These articles described deceptive product labels, how advertising practices target vulnerable groups of people, and even "framed the corporations as manipulative marketers trying to hook consumers on addictive junk food for financial gain." These students also received images of food ads and were instructed to write or draw on these advertisements in order to make them true instead of false.

Because of this intervention, there was a 31 percent reduction in unhealthy drink and snack purchases made by these study participants (particularly males) in the following three months.

Chicago Booth's, Christopher J. Bryan, explains,

Food marketing is deliberately designed to create positive emotional associations with junk food, to connect it with feelings of happiness and fun.

If you're suffering from a junk food addiction yourself, try reframing how you view food marketing campaigns. Getting yourself informed on what's really happening in advertising is a method that is brief, inexpensive, and ultimately effective.
