Younger people and those with less formal education tend to consume more ultra-processed foods, while people living in rural areas consume less, indicating that UPF intake is shaped by age, education, and where people live.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review could determine whether younger age, lower education, and urban residence consistently predict higher UPF intake across global populations.
A systematic review and meta-analysis of 25+ nationally representative surveys measuring UPF intake by age group, education level, and urban/rural residence, with pooled odds ratios and subgroup analyses by income level and region.
A prospective cohort study could determine whether younger age and lower education predict increases in UPF intake over time.
A multicenter cohort study following 12,000 adults aged 18–40 across Latin America and Spain for 5 years, measuring UPF intake annually, with baseline assessment of education, urban/rural residence, and socioeconomic status, adjusting for income mobility.
A cross-sectional study can identify the distribution of UPF intake across age, education, and urban/rural groups at a single point in time.
A nationally representative cross-sectional survey of 15,000 adults across 14 Latin American countries and Spain using stratified random sampling, measuring UPF intake via 24-hour recalls and sociodemographic variables via structured interviews.
