Adherence
Front-of-package nutrient warning labels on sugar-sweetened beverages and ultra-processed foods significantly increase consumer attention, comprehension, and negative affect, leading to reduced behavioral intentions to purchase these products compared to no-label controls.
Look for products with clear, binary warning labels (like octagons stating 'High in Sugar'). These labels are designed to grab your attention and signal health risks quickly. While they may not change your behavior instantly, they are more effective at helping you identify unhealthy options than complex rating systems. Use them as a quick filter to avoid products with high levels of added sugars, sodium, or saturated fats.
FoP nutrient warnings were visually attended to by consumers, easy to understand, helped consumers identify products high in nutrients of concern, and discouraged them from purchasing these products
Why this rating
Based on 22 randomized controlled experiments, though many measured intentions rather than actual purchase.
