Summary

This paper, published in Nature Food in 2021, analyses the nutrient density of food systems globally, drawing on national food supply or dietary data to characterise how different food system configurations relate to nutritional quality. The study likely employs nutrient density scoring or adequacy frameworks to compare systems across regions or income levels. It contributes to understanding how structural features of food systems — including production diversity, food processing, and supply chain composition — shape the nutritional value of available diets.

UK applicability

Whilst the study is global in scope, its findings on the relationship between food system structure and nutrient density are directly relevant to UK food policy debates around dietary quality, food reformulation, and the nutritional adequacy of the national food supply. UK policymakers and researchers may use its frameworks to benchmark domestic food system performance against international comparators.

Key measures

Nutrient density indices; dietary nutrient adequacy; food system composition metrics; national food supply data

Outcomes reported

The study assessed and compared nutrient density across global food systems, examining how food production and supply patterns affect the nutritional quality of diets at a population level. It likely reported nutrient density scores or indices across different food system typologies or national food supplies.
