Summary
This paper, published in One Earth in 2022, investigates the relationship between the nutritional value of foods and their environmental footprint across a range of food commodities. Drawing likely on existing life cycle assessment data and nutritional databases, it aims to identify foods and dietary patterns that can simultaneously support human health and reduce environmental burden. The work contributes to the growing evidence base informing sustainable healthy diet frameworks, though specific findings should be verified against the published article.
UK applicability
Although the study appears to take a global or international scope, its findings are broadly applicable to UK food policy discussions around sustainable diets, particularly in the context of the National Food Strategy and commitments under the Environmental Land Management scheme. UK practitioners and policymakers could use this evidence to guide dietary recommendations that balance nutritional adequacy with net-zero targets.
Key measures
Nutrient density scores (e.g. nutrient rich food index or similar composite metric); greenhouse gas emissions (kg CO2-eq per kg food or per unit nutrient); land use (m² per kg food); water use (litres per kg food)
Outcomes reported
The study likely examined how the nutritional quality of various food groups compares with their associated environmental costs, such as greenhouse gas emissions, land use, and water use. It probably identified food categories that offer high nutrient density relative to low environmental impact, and those where the trade-off is less favourable.
