Summary
This policy-oriented assessment integrates findings from the Blue Food Assessment to propose four evidence-based policy objectives for leveraging aquatic foods in national food systems. The authors develop an analytical framework that contextualises blue food contributions across nutritional security, environmental sustainability, economic development and climate adaptation, identifying distinct policy priorities for different regions based on their epidemiological, environmental and socio-economic profiles.
UK applicability
The United Kingdom, as a Global North nation with high ruminant meat consumption and associated cardiovascular disease burden, may find relevance in the objective to increase moderate consumption of low-impact seafood as a health-promoting alternative. The framework's emphasis on environmental footprints and climate resilience may also inform UK food system policy, though specific applicability depends on the degree to which UK-specific data were incorporated.
Key measures
Nutritional contributions (vitamin B12, omega-3 fatty acids); environmental impact (greenhouse gas emissions, land and water use); economic and livelihood outcomes; climate vulnerability and adaptation relevance by country
Outcomes reported
The study assessed nutritional, environmental, economic and justice dimensions of blue foods globally and translated findings into four policy objectives relevant to different national contexts. The analysis identified how blue food consumption could address micronutrient deficiencies in African and South American nations, reduce cardiovascular disease and greenhouse gas emissions in Global North countries, and build climate resilience in high-risk regions.
