Summary
This study provides empirical evidence on the health implications of international food trade by linking bilateral trade flows for 2019 with food-specific risk–disease epidemiological relationships. The findings demonstrate that food trade effects on health are commodity-dependent: imports of plant-based foods (fruits, vegetables, legumes, nuts) reduce dietary risk and mortality, whilst red meat imports increase both. The magnitude of the estimated global health impact suggests that health considerations should be integrated into trade and agriculture policy design.
UK applicability
The United Kingdom, as a significant food-importing nation, may find these results relevant to import policy and food security strategy, particularly regarding the balance of commodity imports and their net health effects. However, the analysis is based on 2019 global patterns and may not account for UK-specific dietary composition or food supply vulnerabilities.
Key measures
Diet-related mortality attributable to international food trade by commodity type; non-communicable disease burden; deaths averted or increased by food category
Outcomes reported
The study quantified the global health burden attributable to international food trade by estimating diet-related mortality changes associated with imports of specific food commodities. Imports of fruits, vegetables, legumes and nuts were associated with approximately 1.4 million averted deaths from non-communicable diseases globally, whilst red meat imports were associated with approximately 150,000 excess deaths.
