What was done

Researchers linked NHANES August 2021–August 2023 dietary data with National Cancer Institute ultra-processed food classifications based on a single Day 1 dietary recall interview. Mean percentage of calories from ultra-processed foods was assessed by sex, age, family income, and 10-year trends using t-tests and polynomial regression, accounting for the complex survey design and sample weights.

What was found

Youth aged 1–18 years consumed 61.9% of total daily calories from ultra-processed foods, whereas adults aged 19 and older consumed 53.0%. Four of the top five sources for both youth and adults were sandwiches (including burgers), sweet bakery products, savory snacks, and sweetened beverages. Mean ultra-processed food calorie consumption decreased among adults between 2013–2014 and August 2021–August 2023.

Why it matters

This report provides updated national benchmark data showing that ultra-processed foods continue to constitute the majority of caloric intake among both children and adults in the United States, despite a modest 10-year downward trend in adults.

Limits

Participant sample size is not stated in the abstract. Dietary assessment relied on a single 24-hour recall, which is subject to recall bias, reporting errors, and day-to-day variability. The cross-sectional design cannot evaluate longitudinal individual-level trajectories or health outcomes.
