19 Oct 2018 --- Moving the location of fruit and vegetables in stores can lead to a 15 percent sales increase, a University of Warwick study has found. Researchers found that sales increased without any further messaging or marketing when the placement of fruit and vegetables changed, suggesting a simple “nudge” can lead to healthier diets for young adults. The findings, published in BMC Public Health, were based on data collected between 2012 and 2017 in a real University campus grocery store.
