Despite extensive research on how to persuade consumers to improve their diets, academicians have largely failed to present food retailers with easy-to-use suggestions. Brian Wansink, director of Cornell’s Food and Brand Lab and a leading expert in changing eating behavior, seeks to change this by providing an organizing framework that integrates insights from marketing, nutrition, psychology, public health, and behavioral economics research to suggest dozens of small, low-cost, in-store changes that retailers can use to boost sales of fish versus hamburger and apples instead of candy bars.
