Abstract

In this cross-sectional study of Korean youths, the estimated proportion of energy intake from ultraprocessed foods increased from 2007 to 2024, indicating that ultraprocessed foods became a more dominant part of Korean youths' diets, especially among older youths and those without obesity. These findings suggest the need for monitoring and preventive strategies to reduce intake.
