Beverages play an important role in the diets of adolescents because they help to maintain hydration and can provide important nutrients, such as calcium, vitamin D, and vitamin C (1). However, some beverages, such as sugar-sweetened beverages (SSBs) (e.g., soda or pop), provide calories with no beneficial nutrients. Beverage consumption patterns among American youth have changed over time; however, little is known about differences in consumption of various beverages by demographic characteristics such as grade in school, free/reduced price lunch eligibility, and race/ethnicity (2). CDC analyzed data from the 2007-2015 national Youth Risk Behavior Surveys (YRBS) to assess whether the prevalence of drinking non-diet soda or pop (soda), milk, and 100% fruit juice (juice) has significantly changed over time among U.S. high school students. During 2007-2015, daily soda consumption decreased significantly from 33.8% to 20.5%. During 2007-2011, daily milk and juice consumption did not significantly change, but during 2011-2015 daily milk and juice consumption decreased from 44.3% to 37.4% and from 27.2% to 21.6%, respectively. Although a decrease in daily soda consumption is a positive change, soda consumption remains high. Although there is not a specific recommendation for sugar-sweetened beverage consumption, the Dietary Guidelines for Americans 2015-2020 recommend that U.S. residents reduce sugar-sweetened beverage and sweet consumption to reduce intake of added sugars to less than 10% of calories per day. The Dietary Guidelines for Americans 2015-2020 recommend that persons choose beverages with no added sugars, such as water, in place of sugar-sweetened beverages, as one strategy for achieving the added sugars recommendation. Adolescents might need additional support in choosing more healthful beverages, such as low-fat milk, in place of SSBs.
饮料在青少年饮食中起着重要作用,因为它们有助于保持水分,并能提供重要的营养素,如钙、维生素D和维生素C(1)。然而,一些饮料,如含糖饮料(SSB)(如苏打水或汽水),只提供热量而没有有益的营养素。美国青少年的饮料消费模式随时间发生了变化;然而,对于不同人口特征(如年级、免费/减价午餐资格以及种族/族裔)的青少年在各类饮料消费上的差异,人们了解甚少(2)。美国疾病控制与预防中心(CDC)分析了2007 - 2015年全国青少年风险行为调查(YRBS)的数据,以评估美国高中生饮用非低糖汽水或汽水、牛奶和100%果汁的比例随时间是否有显著变化。在2007 - 2015年期间,每日汽水消费量从33.8%显著下降至20.5%。在2007 - 2011年期间,每日牛奶和果汁消费量没有显著变化,但在2011 - 2015年期间,每日牛奶消费量从44.3%降至37.4%,每日果汁消费量从27.2%降至21.6%。虽然每日汽水消费量的下降是一个积极变化,但汽水消费量仍然很高。虽然对于含糖饮料的消费没有具体建议,但《2015 - 2020年美国膳食指南》建议美国居民减少含糖饮料和甜食的消费,将添加糖的摄入量降至每日热量摄入的10%以下。《2015 - 2020年美国膳食指南》建议人们选择无添加糖的饮料,如水,以替代含糖饮料,作为实现添加糖建议摄入量的一种策略。青少年在选择更健康的饮料(如低脂牛奶)以替代含糖饮料方面可能需要更多支持。
