Summary

This Nature policy paper integrates findings from the Blue Food Assessment to propose four country-contextualised policy objectives for leveraging blue foods in national food systems. The analysis identifies that African and South American nations could address micronutrient deficiencies through culturally appropriate blue food consumption, whilst global North nations could reduce cardiovascular disease and emissions by substituting ruminant meat with low-impact seafood. The framework identifies countries at high climate adaptation risk and provides decision makers with tools to assess geographically relevant trade-offs and co-benefits.

UK applicability

For the United Kingdom, the framework's application would likely centre on the global North objective of reducing ruminant meat consumption and associated emissions through moderate, low-impact seafood intake to address cardiovascular disease. The findings may inform UK food policy and dietary guidance but do not specifically address UK-specific nutritional vulnerabilities or aquaculture systems.

Key measures

Nutritional dimensions (vitamin B12, omega-3 fatty acids), environmental impacts (greenhouse gas emissions, land and water use), economic and justice considerations, country-level policy relevance assessments

Outcomes reported

The study assessed the relevance of four policy objectives for blue foods (ensuring critical nutrient supplies, providing healthy alternatives to terrestrial meat, reducing dietary environmental footprints, and safeguarding blue food livelihoods under climate change) across individual countries. It identified context-specific opportunities and trade-offs for realising blue food contributions to national food systems.
