Evolution of Front-of-Pack Nutrition Food Labeling Policies and Practices

Front-of-pack (FOP) nutrition food labeling has emerged as one of the most visible and widely adopted nutrition policy tools aimed at improving population diets and reducing the burden of diet-related non-communicable diseases. Over the past two decades, FOP labeling systems have evolved from voluntary, information-based schemes—such as guideline daily amounts and interpretive summary indicators—towards more directive and mandatory approaches, including nutrient warning labels.Chile has played a pioneering role in this evolution and was the first country that implemented mandatory FOP warning labels. Similar rules have since been implemented elsewhere in South America, and the approach is now expanding to higher-income countries such as Canada. Food labeling policies are often accompanied by complementary policies such as restrictions on marketing to children and school food standards. These regulatory “stick” approaches contrast with alternative “carrot” strategies that emphasized consumer education, voluntary industry reformulation, and advisory labels. Early evidence from the South America region has already demonstrated health-promoting impacts on product reformulation, consumer purchasing behavior, and industry practices, providing valuable lessons for global nutrition governance.In recent years, these policy models have increasingly influenced debates and regulatory developments beyond Latin America. While some countries are considering mandatory FOP labeling systems, the European Union and other regions continue to debate the merits of (mostly voluntarily) advisory and warning schemes. This global diffusion raises critical questions about policy transferability, contextual adaptation, political economy, trade considerations, and long-term effectiveness. A common question is whether food labels should primarily inform consumers, or should they more explicitly discourage consumption of less healthy products through warnings and restrictions? There is still also much to be understood about how FOP labels interact with industry responses, consumer understanding, equity considerations, and broader food system transformations. This Research Topic aims to highlight interdisciplinary research on the design, implementation, effectiveness, and policy implications of front-of-pack food labeling systems worldwide. By drawing on lessons learned from already implemented and emerging experiences, this collection seeks to inform evidence-based policy development and contribute to more effective, equitable, and coherent nutrition labeling strategies. We invite contributions addressing a wide range of topics, including:• The evolution of front-of-pack food labeling systems globally; carrot vs. stick approaches: conceptual frameworks and empirical comparisons• Comparative effectiveness of advisory versus warning-based FOP labels• Lessons learned from existing FOP labeling policies, including about voluntarily vs. mandatory practices• Impacts of FOP labeling on consumer behavior and dietary patterns• Food industry reformulation and strategic responses to labeling regulations• Alignment of FOP labeling systems with dietary guidelines• Political economy, governance, and industry responses to mandatory labeling• Interactions between FOP labeling and complementary food policies, including marketing restrictions, fiscal measures and procurement rulesThis Research Topic accepts the following article types, unless otherwise specified in the Research Topic description:• Brief Research Report• Opinion • Original Research• Perspective• Policy and Practice Reviews• Review• Systematic Review• Conceptual Analysis• Data Report• General Commentary• Methods• Mini Review Topic editors: Sean B.
