Research is limited on added sugars in school meals and children's dietary intakes after the 2015-2020 Dietary Guidelines for Americans (DGA) recommended that added sugars be limited to less than 10% of total calories. This analysis uses data from the School Nutrition and Meal Cost Study (SNMCS) to examine levels of added sugars in: (1) school meals and (2) children's dietary intakes at breakfast, lunch, and over 24 h on school days. SNMCS data were collected in the 2014-2015 school year after updated nutrition standards for school meals were implemented. Most schools exceeded the DGA limit for added sugars at breakfast (92%), while 69% exceeded the limit at lunch. The leading source of added sugars in school meals (both breakfasts and lunches) was flavored skim milk. More than 62% of children consumed breakfasts that exceeded the DGA limit, and almost half (47%) consumed lunches that exceeded the limit. Leading sources of added sugars in the breakfasts consumed by children were sweetened cold cereals and condiments and toppings; leading sources of added sugars in children's lunches were flavored skim milk and cake. Over 24 h, 63% of children exceeded the DGA limit. These findings show that school meals and children's dietary intakes are high in added sugars relative to the DGA limit and provide insights into the types of foods that should be targeted in order to decrease levels of added sugars.
研究发现,在 2015-2020 年《美国人饮食指南》(DGA)建议将添加糖的摄入量限制在总卡路里的 10%以下后,学校餐和儿童饮食中添加糖的摄入量有限。本分析使用来自学校营养和膳食成本研究(SNMCS)的数据,研究了以下方面的添加糖水平:(1)学校餐;(2)儿童在上学日早餐、午餐和 24 小时内的饮食摄入量。SNMCS 数据是在更新后的学校膳食营养标准实施后的 2014-2015 学年收集的。大多数学校的早餐添加糖含量超过了 DGA 的限制(92%),而 69%的学校午餐添加糖含量超过了限制。学校餐(早餐和午餐)中添加糖的主要来源是风味脱脂牛奶。超过 62%的儿童早餐摄入超过 DGA 限制,近一半(47%)的儿童午餐摄入超过限制。儿童早餐中添加糖的主要来源是加糖冷麦片和调味品和浇头;儿童午餐中添加糖的主要来源是风味脱脂牛奶和蛋糕。24 小时内,63%的儿童超过了 DGA 限制。这些发现表明,与 DGA 限制相比,学校餐和儿童饮食中添加糖含量较高,并深入了解了应该针对哪些类型的食物来降低添加糖含量。
