The volunteers showed higher carotenoid concentrations than found in previous studies. A significant correlation of healthy lifestyle habits and a high antioxidant status could be determined. Subjects improved their nutritional habits and significantly increased their carotenoid concentration during intervention. Follow-up five months later showed a consolidation of the increase. The investigations show that a healthy diet and a well-balanced lifestyle correlate with a high cutaneous antioxidant concentration and that spectroscopic biofeedback measurement of cutaneous carotenoids as part of an integrated prevention program is a feasible and effective means to raise the health awareness in adolescents.}, language = {en} }
