Cohort study shows adverse behavioral outcomes in preschoolers associated with ultraprocessed food intake, suggesting dietary changes may benefit mental health.
In this cohort study of preschoolers in Canada, higher UPF intake was associated with adverse behavioral and emotional symptoms by age 5 years. These findings suggest that replacing UPF with MPF during the preschool years may support healthier behavioral development, with potential benefits for long-term mental health. These findings also support ongoing policy actions that promote MPF and underscore the need for early-life dietary interventions.
