Summary
This 2022 modelling study by Guo et al. examines the environmental and human health implications of potential dietary shifts in China. The work, published in One Earth, appears to assess how changes in food consumption patterns could simultaneously affect environmental sustainability (resource use, emissions) and population-level health outcomes (nutrient adequacy, chronic disease risk), identifying areas where improvements in one domain may conflict with or support the other. The analysis contributes to understanding how dietary change strategies must balance competing sustainability and nutrition objectives in a major food-consuming nation.
UK applicability
Whilst focused on China's dietary context and food system, the methodological approach to quantifying environment–health trade-offs in dietary transitions may inform UK food policy discussions around sustainable diets and public health nutrition. However, direct applicability is limited due to differences in baseline diets, agricultural systems, and population health profiles.
Key measures
As suggested by the title: environmental metrics (likely greenhouse gas emissions, land use, water use); health metrics (likely disease burden, nutritional adequacy); trade-offs between these domains
Outcomes reported
The study examined potential environmental and human health impacts of dietary shifts in China, comparing scenarios of dietary change against baseline intake patterns. It evaluated trade-offs between environmental sustainability metrics and nutritional health outcomes across different dietary scenarios.
