Summary
This study tested whether color-coded 'Multiple-Traffic Light' (MTL) labels on food products help shoppers make healthier choices. 395 adults in Bahrain used an online grocery store (Bahrain e-Mart) to shop once, either seeing standard labels or MTL labels that color-code nutrients as green (healthy), amber (okay), or red (unhealthy). The goal was to see if MTL labels improve overall diet quality of the selected groceries.
