Summary
This global analysis used 2019 bilateral trade data and food-specific risk–disease relationships to quantify the health impacts of international food trade. The findings reveal that trade effects are bidirectional and category-dependent: imports of plant-based foods (fruits, vegetables, legumes, nuts) were associated with substantial reductions in diet-related mortality (~1.4 million deaths averted globally), whilst red meat imports aggravated dietary risks and increased mortality (~150,000 excess deaths). The results suggest that health impacts of food trade merit integration into health-sensitive trade and agriculture policy.
UK applicability
The United Kingdom is a major importer of both plant-based foods and red meat; these findings directly inform UK trade policy, public health nutrition strategy, and agricultural policy responses post-Brexit. The analysis provides quantified evidence for linking dietary health outcomes to trade composition, relevant to UK food security and NHS prevention priorities.
Key measures
Bilateral trade data (2019); diet-related mortality from non-communicable diseases; attributable mortality by food category (fruits, vegetables, legumes, nuts, red meat)
Outcomes reported
The study quantified the global health burden attributable to international food trade in 2019, estimating mortality impacts by food category. Trade in fruits, vegetables, legumes and nuts was associated with ~1.4 million averted deaths from non-communicable diseases, whilst red meat imports contributed to ~150,000 excess deaths.
