Brian Wansink (born 1960) is an American professor in the fields of consumer behavior and nutritional science. He is a former Executive Director of the USDA's Center for Nutrition Policy and Promotion (CNPP) (2007–2009), and now holds the John S. Dyson Endowed Chair in the Applied Economics and Management Department at Cornell University, where he is director of the Food and Brand Lab.

Wansink is best known for his work on consumer behavior and food and for popularizing terms such as "mindless eating" and "health halos." He is the author of over 100 academic articles and books, including the best-selling books Mindless Eating: Why We Eat More Than We Think (2007) and Slim by Design (2014). He received the 2007 humorous Ig Nobel Prize and was named ABC World News Person of the Week[1] on January 4, 2008.

Biography

Wansink was born in Sioux City, Iowa to John, a bakery production worker, and Naomi, a legal secretary. He received a B.S. from Wayne State College (Nebraska) in 1982 and an M.A. from Drake University in 1984., followed by a Ph.D. in Consumer behaviour in 1990 from Stanford University,

He was a Marketing Professor at the Tuck School of Business at Dartmouth College (1990–1994) and the Wharton School at the University of Pennsylvania (1995–1997), and he was a Marketing, Nutritional Science, Advertising, and Agricultural Economics Professor at the University of Illinois at Urbana-Champaign (1997–2005) before moving to Cornell University (2005 to date). He has also been a Visiting Professor at the Vrije Universiteit (Amsterdam) and Insead (Fountainbleau, France), and he was a Visiting Research Scientist at the U.S. Army Soldier Systems Center (Natick, MA) where he helped design ways to improve the acceptability and consumption of MREs (Meal, Ready-to-Eat) for the United States Army.[citation needed]

Wansink founded the Food and Brand Lab in 1997 at the University of Illinois and the Consumer Education Foundation in 1999. In 2005 he moved both to Cornell University in Ithaca, New York where he founded the Cornell Food and Brand Lab.

From 2007-2009, Wansink had a leave of absence from Cornell to accept a White House appointment as the fourth Executive Director of the USDA's Center for Nutrition Policy and Promotion, where he oversaw the development of the 2010 Dietary Guidelines, the Healthy Eating Index, the Cost of Raising a Child Index, and he is charged with promoting the Dietary Guidelines for Americans, in the form of MyPyramid.

In 2011, Wansink was elected to a one-year-term as president of the Society for Nutrition Education and Behavior .

Work

A consumer psychologist, Wansink is best known for his work on food psychology and eating behavior. This work focuses on how the environment leads or even tricks people into buying and eating food in ways they are unaware. While some of these insights are directed toward responsible food manufacturers and marketers,[2] the majority are focused specifically at parents, dieters, and at the medical and nutrition community. Using a combination of lab studies and field studies, he has used movie popcorn, refillable soup bowls, bartender glasses, candy dishes, Chinese buffets, and ice cream socials to show how various environment cues influence the food intake of unknowing consumers.[3] Although such environmental factors appear unrelated, they generally influence intake by inhibiting consumption monitoring and by suggesting alternative consumption norms.[4]

In contrast to focusing on the macro-food environment as being the cause of the American obesity problem, Wansink's work focuses on the intermediate micro-environment that he contends people can control—their home and their daily habits. In counterpoint to social criticism of the obesigenic nature of our "foodscape," recent work has focused on the more promising changes that can be made in what Wansink refers to as the obesigenic nature of our "kitchenscapes" and "tablescapes."[5]

The studies from the lab have been credited with the development of the 100 calorie packs and the Small Plate Movement, as well as quantifying a wide range of basic insights:

  • Moving from a 12-inch to a 10-inch dinner plate leads people to serve and eat 22% less.[6]
  • A person will eat an average of 92% of any food they serve themselves.[7]
  • The average person makes an excess of 250 decisions about food each day.[8]
  • Low-fat labels lead people to eat 16-23% more total calories.[9]
  • The Nutritional Gatekeeper of a home influences an estimated 72% of all of the food their family eats.[10]
  • Because of visual illusions, people (even professional bartenders) pour 28% more into a short wide glasses than tall ones.[11]
  • 50% of the snack food bought in bulk (such as at a warehouse club store) is eaten within six days of purchase.[12]

In examining the range of what is referred to as "mindless eating," Wansink has made contributions to three principal areas of food-related consumption: consumption norms, taste evaluation, and food selection.

Consumption Norms

Consumption norms are influenced by the wide range of factors that can bias an unknowing person to eat or drink more than they otherwise would. For instance, the size of a serving bowl, a plate, or a package has repeatedly been shown to bias how much a person serves himself and eats by an average of 20-30%.[13] In addition, the perceived variety (color of candies) in an assortment and the proximity of candy on one’s desk has been shown to double how much a person eats over the course of a day.[3] Because people are estimated to make over 200 food-related decisions a day that they are unaware of making, the seemingly inconsequential impact of lighting, plate size, glass shape, music, companion, table arrangement, and dining companion can have a sizable impact on daily food intake.[8] Over the course of year, even a 200 calorie daily change in how much one eats would translate into a 20 pound loss in weight or a 20 pound gain in weight.

Taste Evaluation

The extent to which people enjoy food can be influenced by subtle environmental cues. The names of a food can create either positive or negative predispositions that can unfairly bias a person's perceived taste of a food. Wansink shows this is one reason why advertising or promoting a food as "healthy" unfairly biases people against the taste of a food.[14] Yet using names and visual cues to guide a person's expectations can also enhance their perceived taste of a food. In one study, simply labeling a food as being a Succulent Italian Seafood Filet lead restaurant goers to much more favorably rate the taste than when it was simply labeled Seafood Filet.[15] Similarly, the elegance of dishes and the garnishes on plates has been shown to influence a person’s taste ratings of a food.[3]

Food Selection

The food a person eats at a given time is related to sensory issues, but it is also related to how appropriate they perceive this food for that situation. People are more likely to adopt a food into a new situation (say, eating soup for breakfast) if they focus on the benefits of the food instead of on how it differs from prototypical breakfast foods.[16][17] Food selection has also been linked to favorable past memories of food. This has been suggested as to why men tend to claim their favorite comfort foods are meal-related foods, such as steak, pasta, and soup, while women prefer the more convenient foods, such as ice cream, chocolate, and cookies. For men, meal-related comfort foods evoke feelings of nurturing and attention. Yet for women they evoke memories of preparation and clean-up.[18]

Ig Nobel Prize

The Bottomless Bowl Principle

Brian Wansink is a 2007 recipient of the Ig Nobel Prize in Nutrition. The Ig Nobel prizes are a parody of the Nobel Prize and are awarded for achievements (or sometimes veiled criticisms thereof) that "first make people laugh, and then make them think." Wansink's award was issued for investigating people's appetite for mindless eating by secretly feeding them a self-refilling bowl of soup in the Bottomless Soup Bowl Study. It has come to be known as the Bottomless Bowl Principle.[19]
