The antioxidant and anti-inflammatory effects of carotenoid have been determined to aid in the prevention of a wide range of oxidative disorders, arteriosclerosis, obesity, and various types of cancers. In order to keep high carotenoid levels in the body, much of the vegetable and fruit (V/F) intake is mandatory. However, the actual intake of V/F is not enough in many countries. The aim of this study was to assess whether brief dietary education using the Veggie Meter (VM) that could measure skin carotenoid (SC) levels could induce the increase in carotenoid levels via V/F intake. Two hundred and sixty-one elementary and junior high school students (ages 7−14 years old) received brief educational session and SC evaluation by VM, and the changes in SC levels were examined after 6 months. The baseline VM scores ranged from 131 to 825, and the average significantly increased from 400.0 ± 124.7 (standard deviation) to 447.4 ± 140.4 at Month 6 (p < 0.0001). The percentage of increase at month 6 was negatively correlated with the baseline values (r = −0.36, p < 0.0001). This finding implies that subjects who became aware of their inferiority tended to make a significant effort to change their behavior. The multivariate logistic regression analysis demonstrated that subjects taking much of green and yellow vegetables, drinking vegetable/tomato juice, and eating any fruit had higher VM scores than the average value. In conclusion, the educational approach using VM was supposed to be an effective method of raising awareness of the V/F shortage and increasing V/F intake that could indue the increase in SC levels.
类胡萝卜素的抗氧化和抗炎作用已被确定有助于预防多种氧化紊乱、动脉硬化、肥胖症和各类癌症。为了保持体内高类胡萝卜素水平，大量摄入蔬菜和水果是必不可少的。然而，在许多国家，蔬菜和水果的实际摄入量并不充足。本研究的目的是评估使用能够测量皮肤类胡萝卜素（SC）水平的蔬菜测量仪（VM）进行简短的饮食教育是否能通过摄入蔬菜和水果来促使类胡萝卜素水平升高。261名中小学生（年龄在7至14岁之间）接受了使用VM进行的简短教育课程和SC评估，并在6个月后检查了SC水平的变化。基线VM分数在131至825之间，第6个月时平均分数从400.0±124.7（标准差）显著增加到447.4±140.4（p<0.0001）。第6个月的增加百分比与基线值呈负相关（r = -0.36，p<0.0001）。这一发现表明，意识到自己不足的受试者往往会做出重大努力来改变自己的行为。多因素逻辑回归分析表明，大量食用绿色和黄色蔬菜、饮用蔬菜/番茄汁以及食用任何水果的受试者的VM分数高于平均值。总之，使用VM的教育方法应该是提高对蔬菜和水果短缺的认识以及增加蔬菜和水果摄入量从而促使SC水平升高的有效方法。
