A nutrition rich in fruit and vegetables and a healthy lifestyle become more and more important in the industrial countries to counteract oxidative stress and promote health. For many years, it has been possible to control human cutaneous carotenoids noninvasively by resonance Raman spectroscopic systems and by spatially resolved reflectance spectroscopy.
Ten volunteers took a commercially available fruit and vegetable extract daily for a time period of 5 weeks. A second group served as control group and did not take any supplements (10 volunteers). To monitor the status of the cutaneous carotenoids noninvasively, an optical sensor based on multiple spatially resolved reflectance spectroscopy was applied once a week.
The study could demonstrate that the intake of the supplement significantly increase the cutaneous carotenoid values of the young adults by 50%. The control group without any supplementation showed also significantly increased values, ie, by 10%, which might be due to the fact that their lifestyle was controlled.
The results illustrate that a biofeedback by measuring the skin carotenoids could improve the lifestyle of young adults and that a regular consumption of fruit and vegetables directly or as a drink can increase the concentration of cutaneous carotenoids significantly.
在工业化国家，富含水果和蔬菜的营养以及健康的生活方式对于抵抗氧化应激和促进健康变得越来越重要。多年来，一直可以通过共振拉曼光谱系统和空间分辨反射光谱法对人体皮肤类胡萝卜素进行无创控制。
十名志愿者连续5周每天服用一种市售的水果和蔬菜提取物。另一组作为对照组，不服用任何补充剂（10名志愿者）。为了无创监测皮肤类胡萝卜素的状态，每周使用一次基于多重空间分辨反射光谱法的光学传感器。
该研究表明，服用补充剂可使年轻人的皮肤类胡萝卜素值显著增加50%。未服用任何补充剂的对照组的值也显著增加，即增加了10%，这可能是由于他们的生活方式受到了控制。
结果表明，通过测量皮肤类胡萝卜素进行生物反馈可以改善年轻人的生活方式，并且定期直接食用水果和蔬菜或饮用果蔬汁可以显著提高皮肤类胡萝卜素的浓度。
