Abstract Non-communicable diseases (NCDs) represent the leading cause of mortality globally, accounting for 71% of all deaths worldwide. Unhealthy dietary patterns are recognized as primary modifiable risk factors for NCDs including cardiovascular diseases, type 2 diabetes, certain cancers, and chronic respiratory diseases. This comprehensive review examines global public health nutrition approaches for NCD prevention, analyzing policy frameworks, implementation challenges, and emerging opportunities. Drawing from international evidence, we explore multilevel interventions spanning population-wide policies, community-based programs, and healthcare system integration. The review synthesizes findings on fiscal policies, food environment modifications, nutrition labeling, marketing restrictions, and dietary guidelines while addressing implementation barriers including political economy factors, health inequities, and resource constraints. We identify promising opportunities in digital health technologies, precision nutrition, and multi-sectoral collaboration. The evidence demonstrates that comprehensive, context-adapted nutrition policies can significantly reduce NCD burden when implemented with political commitment, adequate resources, and stakeholder engagement.
