Association between consumption of nonessential energy-dense food and body mass index among Mexican school-aged children: a prospective cohort study
Authors' conclusion
Changes in total NEDF consumption were not associated with changes in BMI in children. However, increases in the consumption of sweet bakery products were associated with BMI gain. NEDF are widely recognized as providing poor nutrition yet, their impact in Mexican children BMI seems to be heterogeneous.
