BACKGROUND
The 2010 Dietary Guidelines for Americans (DGA) recommend that individuals age two years and older reduce intakes of solid fats (SoF) and added sugars (AS; together SoFAS). MyPlate illustrates the proportions of five major food groups to promote healthy eating (Vegetables, Grains, Protein Foods, Fruits and Dairy).
METHODS
To assess if the foods currently consumed by Americans are in concordance with the DGA, food consumption data from What We Eat In America, National Health and Nutrition Examination Survey (WWEIA-NHANES) 2007-2008 (n = 8 527) was used to estimate the proportion of foods that contained SoFAS and to report them by food group. Weighted analysis was conducted to be nationally representative.
RESULTS
The Dairy group contained the highest proportion (93%) of either SoF or AS, followed by Grains (70% SoF; 70% AS; 50% both). Fruits contained the least SoFAS (7%).
CONCLUSIONS
Results suggest that the high proportion of SoFAS in each recommended food group makes it challenging for Americans to reduce their intake of SoFAS.
背景
《2010年美国膳食指南》建议两岁及以上的人群减少固体脂肪（SoF）和添加糖（AS；合称SoFAS）的摄入量。“我的餐盘”展示了五大主要食物组的比例，以促进健康饮食（蔬菜、谷物、蛋白质类食物、水果和乳制品）。
方法
为评估美国人目前的食物消费是否符合《美国膳食指南》，使用了2007 - 2008年美国国家健康与营养检查调查（WWEIA - NHANES）中“我们吃什么”项目的食物消费数据（n = 8527）来估计含SoFAS食物的比例，并按食物组进行报告。进行加权分析以具有全国代表性。
结果
乳制品组含SoF或AS的比例最高（93%），其次是谷物（70%含SoF；70%含AS；50%两者皆含）。水果含SoFAS的比例最低（7%）。
结论
结果表明，每个推荐食物组中SoFAS的高比例使得美国人减少SoFAS摄入量具有挑战性。
