ABSTRACT
Nutrition labeling supports healthier diets by aiding purchase decisions and stimulating reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise evidence on the effectiveness of nutrient declarations and nutrition and health claims on diet-related outcomes. The search spanned 11 academic databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) and vote counting. Data were available from 170 studies. Randomized controlled trials (RCTs) suggest that nutrient declarations likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty) and may have improved the healthfulness of choices (low certainty) versus no label. RCT evidence also suggests that claims likely increased consumer perceptions of food healthfulness and increased choice and purchases of labeled foods (both moderate certainty), irrespective of nutritional quality. To improve label understanding and avoid misinterpretation, nutrient declarations may incorporate interpretive elements and claims can apply disqualifying conditions for their usage, on the basis of overall nutritional quality.
