Financialization, Food Sovereignty, and Oral Health: A Structured Narrative Review Within the One Health Framework for Sustainable Food Systems

Contemporary food systems are increasingly shaped by financialization, corporate concentration, and unequal distributions of power that influence food production, food environments, dietary exposures, and population health. However, the relationships among food-system financialization, food sovereignty, and oral health remain insufficiently integrated within food-security, sustainability, and One Health research. This structured narrative review critically synthesized interdisciplinary evidence from Scopus, Web of Science, PubMed/MEDLINE, Google Scholar, citation searching, and authoritative institutional sources to examine these relationships and develop an integrative conceptual framework. The synthesis indicates that financialization may influence health through market concentration, commodity dependence, corporate control of food environments, and the expansion of ultra-processed foods, whereas food sovereignty may modify these pathways by strengthening agency, equitable resource distribution, local governance, and ecological resilience. Dietary exposures and related biological mechanisms provide plausible pathways through which these structural processes may contribute to oral-health outcomes and inequalities. The proposed framework integrates food-system structures, governance, food environments, dietary exposures, biological pathways, oral health, and One Health implications within a common analytical model. Oral health is therefore proposed as a potential biological interface through which food-system transformations and inequalities may become measurable. Empirical research is required to test these pathways and evaluate the framework’s applicability across populations and food-system contexts.
