First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether adding color-coded nutrition labels (green, amber, red) to food products in an online grocery store helps shoppers choose healthier items. 395 adults in Bahrain completed a one-time shopping trip in a simulated online store. The researchers compared the diet quality of purchases made with and without these labels to see if the labels encourage healthier selections.
