A diet high in fruits and vegetables is associated with a decreased risk for many chronic diseases and some cancers, and can aid in weight management. Current daily fruit and vegetable recommendations for adolescents who participate in <30 minutes of physical activity daily are 1.5 cups of fruit and 2.5 cups of vegetables for females and 2 cups of fruit and 3 cups of vegetables for males (1 cup is approximately equal to one medium apple, eight strawberries, 12 baby carrots, or one large tomato). However, recently published data from the National Health and Nutrition Examination Survey 2003-2004 revealed that consumption was considerably below these levels. To assess fruit and vegetable consumption among high school students, CDC analyzed data from the 2010 National Youth Physical Activity and Nutrition Study (NYPANS). This report describes the results of that analysis, which indicated that, in 2010, the median number of times per day that high school students consumed fruits and vegetables was 1.2 for both. For vegetables, the median number of times per day was lower for non-Hispanic black students (1.0) and Hispanic students (1.1) than non-Hispanic white students (1.4). Overall, 28.5% of high school students consumed fruit <1 time daily, and 33.2% of high school students consumed vegetables <1 time daily. The infrequent fruit and vegetable consumption by high school students highlights the need for effective strategies to increase consumption. Policy and environmental approaches to provide greater access to and availability of fruits and vegetables are among the strategies that schools and communities might choose to achieve this goal.
多吃水果和蔬菜与许多慢性疾病和某些癌症的风险降低有关,并且有助于体重管理。目前,对于每天参与<30 分钟体育活动的青少年,水果和蔬菜的日常推荐摄入量为女性 1.5 杯水果和 2.5 杯蔬菜,男性 2 杯水果和 3 杯蔬菜(1 杯约等于一个中等大小的苹果、8 个草莓、12 个小胡萝卜或一个大番茄)。然而,最近发表的 2003-2004 年全国健康和营养调查数据显示,实际摄入量远低于这些水平。为了评估高中生的水果和蔬菜摄入量,疾病预防控制中心分析了 2010 年全国青少年体育活动和营养调查(NYPANS)的数据。本报告介绍了该分析的结果,结果表明,2010 年,高中生每天食用水果和蔬菜的中位数次数均为 1.2 次。就蔬菜而言,非西班牙裔黑人学生(1.0)和西班牙裔学生(1.1)每天食用蔬菜的中位数次数低于非西班牙裔白人学生(1.4)。总体而言,28.5%的高中生每天食用水果<1 次,33.2%的高中生每天食用蔬菜<1 次。高中生水果和蔬菜的摄入频率较低,这突出表明需要采取有效的策略来增加摄入量。为了提供更多获取和提供水果和蔬菜的机会,政策和环境方法是学校和社区可能选择实现这一目标的策略之一。
