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.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Multiple-Traffic Light (MTL) food labels
What this could lead to: If effective, MTL labels could help people make healthier food choices when shopping online, potentially improving diet quality at a population level.
What could go wrong: This was a one-time online shopping experiment, not a real-world long-term study. Results may not reflect actual shopping habits or lasting dietary changes.
