A team of researchers from Duke-NUS Medical School has developed a digital toolkit that significantly improves the nutritional quality of online grocery purchases. Published in the American Journal of Preventive Medicine<\/em><\/a>, the study demonstrates how simple interventions, like color-coded labels and healthier alternative prompts, can reduce calories and unhealthy nutrients in shoppers’ carts\u2014a potential game-changer in combating chronic diseases globally.<\/p>\n\n\n\n

The study involved a randomized trial on NUSMart, an online grocery platform designed by the researchers. Participants were divided into two groups: one used a standard version of the store, while the other interacted with a version enhanced with four digital features. These included traffic light-style nutritional labels (green for healthiest, red with an “X” for least healthy), sorting items by nutritional value, real-time cart feedback via a pie chart, and suggestions for healthier alternatives.<\/p>\n\n\n\n

Using the Nutri-Score (NS) grading system, the team found that the interventions improved the average nutritional quality of carts from a grade C to B. Shoppers also purchased fewer calories (12.86 kcal less), less fat, sugar, and sodium per order. Notably, these healthier choices persisted across all three orders placed during the trial.<\/p>\n\n\n\n

Assistant Professor Soye Shin, the study’s first author, emphasized the scalability of these tools: “Our goal was to create low-cost, effective nudges for online grocery platforms. The results show promising potential for improving public health.”<\/p>\n\n\n\n

Senior author Professor Eric Finkelstein highlighted the next steps: “Collaborating with retailers to integrate these features into existing stores will unlock their full impact.” Professor Patrick Tan, Duke-NUS Senior Vice-Dean for Research, added, “This research translates scientific insights into practical tools that empower healthier population-wide choices.”<\/p>\n\n\n\n

The study underscores the value of multi-pronged digital interventions in promoting healthier diets. Future research will explore the long-term health effects and extend the toolkit to low-income consumers. As online grocery shopping grows, such innovations could play a pivotal role in global health strategies.<\/p>\n","protected":false},"excerpt":{"rendered":"
