High consumption of ultra-processed foods is associated with lower muscle mass in Brazilian adolescents in the RPS birth cohort
Investigate the association between percent contribution of ultra-processed foods to total dietary energy intake and measurements of body composition obtained using high-validity methods.
Total average energy consumption was 2919.7 kcal, with 58% (1634.9 kcal) derived from natural or minimally processed foods and 37% (1136.5 kcal) from ultra-processed products. In the adjusted analyses, BMI, muscle mass, and LMI were inversely associated with consumption of ultra-processed foods. A 1% increase in the percent contribution of ultra-processed items to total dietary energy intake was associated with a 0.04 kg decrease in muscle mass (_ = –0.04; 95% confidence interval [CI], –0.06 to –0.02; P < 0.001) and a 0.01 kg/m2 decrease in lean body mass (_ = –0.01; 95% CI, –0.02 to –0.01; P < 0.001).
