However, longitudinal studies associating ultra-processed food consumption with gut microbiota composition, especially among adolescents in low- and middle-income countries, are lacking. This study aimed to explore this association using data collected from 364 participants at ages 6, 11, and 12 years from the 2004 Pelotas (Brazil) Birth Cohort. Microbiota data …
