Intake of foods with anti-oxidative properties among Croatian adolescents

The dietary intake of 12 nutrients with anti-oxidative properties (magnesium, zinc, copper, manganese, selenium, vitamins A, C and E, ω-6 and ω-3 polyunsaturated fatty acids (PUFAs), flavonoids, and isoflavones), along with their major food sources, were analyzed by a food frequency questionnaire (FFQ) administered to 422 first-year students from the University of Zagreb, Croatia. Antioxidants intake in adolescents was generally sufficient, but intakes of magnesium and vitamin E were below 80% RDA in both sexes. Above-TUIL vitamin A intake was found in 13% of male and 3% of female adolescents with intakes up to 1400% RDA. Regional differences were significant, with higher intakes of magnesium, copper and selenium in females and lower ω-6/ω-3 PUFAs ratio in both genders in coastal compared to continental region. In conclusion, this study indicates the need for gender- and region-specific educational strategies for implementation of a healthier diet among Croatian adolescents.
