Summary
This paper by Popkin and Ng, published in The Lancet Global Health, provides a global overview of ultra-processed food consumption using the NOVA classification framework. It synthesises available dietary data to document the penetration of ultra-processed foods into food systems across different world regions, with particular attention to disparities between high-, middle-, and low-income countries. The paper's contribution lies in contextualising the global dietary transition towards industrially processed foods and its implications for public health.
UK applicability
The UK is among the high-income countries likely referenced in this global analysis, where ultra-processed foods are estimated to constitute a substantial proportion of dietary energy intake. The findings are directly relevant to UK public health policy, including debates around food labelling, dietary guidelines, and the regulation of highly processed food marketing.
Key measures
Ultra-processed food consumption (% of total energy intake); national and regional dietary data; NOVA food classification system
Outcomes reported
The study examined trends in ultra-processed food consumption across countries and regions globally, assessing the extent to which these products contribute to total dietary energy intake. It likely reported variation by income level, region, and over time, highlighting the growing dietary share of ultra-processed foods in both high- and middle-income countries.
