In a randomized trial, simple digital features in an online grocery shopping platform significantly improved the nutritional quality of shoppers’ carts. The researchers tested a new toolkit with strategic and simple options, including color-coded nutritional quality signals and a healthier alternative prompt for healthier online grocery choices. The study by Duke-NUS Medical School, Singapore, included 328 participants shopping three times within three to six weeks on NUSmart, an online grocery store designed by the research team. One group shopped at a standard store, and the other group at a store with additional features for healthier choices.
