Diet quality and consumption of ultra-processed foods according to age groups in Brazil: insights from the National Dietary Survey 2017–2018

Summary

This cross-sectional analysis of Brazil's National Dietary Survey 2017–2018 characterises the consumption of ultra-processed foods across age groups and examines their relationship with overall diet quality. The paper likely documents patterns of ultra-processed food intake and demonstrates how this consumption correlates with dietary quality metrics, contributing evidence on the public health relevance of ultra-processed foods in a middle-income country context. The findings may inform dietary guidelines and food policy discussions in Brazil and comparable settings.

Regional applicability

Whilst this study is Brazil-specific, the methodological approach and findings regarding age-related ultra-processed food consumption patterns may inform comparative analysis of similar dietary trends in the UK food supply. However, direct applicability is limited due to differences in food systems, cultural dietary practices, and regulatory environments between Brazil and the United Kingdom.

Key measures

Ultra-processed food consumption prevalence and quantity by age group; diet quality indices; dietary diversity; nutrient intake; association between ultra-processed food consumption and diet quality

Outcomes reported

The study analysed the relationship between ultra-processed food consumption and overall diet quality across different age groups using nationally representative dietary survey data. It quantified ultra-processed food intake patterns and their association with dietary quality metrics by age cohort.
