Mapping Global Research on Packaged Food Labeling Policy: A Bibliometric Study

Abstract

Food labeling policies are an important strategy in combating noncommunicable diseases. Front-of-pack labeling (FOPL) policies have been adopted by various countries with different approaches, both mandatory and voluntary, which aim to effectively convey the health risks associated with excessive consumption of sugar, salt, and fat. However, the effectiveness of these policies is highly dependent on the social and cultural context, nutrition literacy levels, and regulatory capacity in each country. This study aims to map and analyze global trends in scientific literature on packaged food labeling policies over the past decade (2015–2024). Bibliometric methods were applied to 1,843 documents from Scopus, analyzed using VOSviewer. The results show a significant increase in publication volume, with the United States, Australia, and the United Kingdom dominating. Thematic analysis revealed five main clusters: consumer behavior, health policy, sustainability, research methodology, and global health. This research is multidisciplinary but still concentrated in developed countries. Inclusive global collaboration and a contextual approach are needed to improve the implementation of labeling policies in low and middle income countries.
