Adolescent Whole Grain Intake Linked to Lower Insulin, Higher Folate

To assess the benefits of whole grains for adolescents U.S. researchers reviewed dietary data from 4,928 adolescents aged 12-19, about evenly divided between boys and girls. They compared this data to several health measures, and found that, in both genders, those with the highest whole grain consumption had lower fasting insulin levels, and higher folate levels. Girls who ate the most whole grains also had lower C-peptide concentrations (a marker for good insulin function), while boys has lower homocysteine concentrations (a marker for reduced cardiovascular risk).
