Summary
This global analysis quantifies the differential health impacts of international food trade, using 2019 bilateral trade data and established food-disease risk relationships. Whilst imports of plant-based foods (fruits, vegetables, legumes, nuts) were associated with substantial reductions in non-communicable disease mortality (~1.4 million deaths globally), red meat imports increased dietary risks and mortality (~150,000 deaths). The findings suggest that trade policy and agricultural governance should systematically account for health impacts of specific food commodities.
UK applicability
The United Kingdom, as a major food-importing economy, is directly relevant to this analysis. UK dietary risks and non-communicable disease burden are influenced by the composition of its food imports; the study suggests that UK policy on agricultural trade agreements and food supply chain resilience should incorporate health impact assessment alongside economic and environmental considerations.
Key measures
Diet-related mortality (deaths prevented or caused); dietary risk reduction or aggravation; bilateral food trade volumes by commodity type (2019)
Outcomes reported
The study quantified the global health impact of international food trade by estimating diet-related mortality attributable to imports of specific food categories. Imports of fruits, vegetables, legumes and nuts were associated with ~1.4 million deaths prevented globally, whilst red meat imports were associated with ~150,000 excess deaths.
