The Potential Effectiveness of Front-of-Pack Nutrition Labeling for Improving Population Diets

Abstract

Nutrition labeling on the front of food packages can support more healthful purchase decisions and encourage favorable reformulation. This systematic literature review applied Cochrane methods to synthesize and appraise the evidence on the effectiveness of front-of-pack labeling (FOPL) on diet-related outcomes and food reformulation to inform policy recommendations. The search was conducted on 11 academic and gray literature databases, from inception to July 2022. Evidence was synthesized using GRADE (Grading of Recommendations, Assessment, Development, and Evaluation), vote counting, and meta-analyses, where appropriate. Overall, 221 articles were included in the review. The randomized controlled trial evidence suggested that, compared with when no FOPL was present, FOPL likely improved consumer understanding of the nutritional quality/content of foods (moderate certainty of evidence), and the healthfulness of food choices (moderate certainty) and purchases (moderate certainty). Interpretive FOPL had a greater effect on these outcomes compared with noninterpretive systems (moderate certainty). There was inconsistency in the best-performing interpretive FOPL system.
