USDA National Nutrient Database for Standard Reference Dataset for What We Eat In America, NHANES (Survey-SR)

The dataset, Survey-SR, provides the nutrient data for assessing dietary intakes from the national survey What We Eat In America, National Health and Nutrition Examination Survey (WWEIA, NHANES). Historically, USDA databases have been used for national nutrition monitoring (1). Currently, the Food and Nutrient Database for Dietary Studies (FNDDS) (2), is used by Food Surveys Research Group, ARS, to process dietary intake data from WWEIA, NHANES. Nutrient values for FNDDS are based on Survey-SR. Survey-SR was referred to as the "Primary Data Set" in older publications. Early versions of the dataset were composed mainly of commodity-type items such as wheat flour, sugar, milk, etc. However, with increased consumption of commercial processed and restaurant foods and changes in how national nutrition monitoring data are used (1), many commercial processed and restaurant items have been added to Survey-SR. 

The current version, Survey-SR 2013-2014, is mainly based on the USDA National Nutrient Database for Standard Reference (SR) 28 (2) and contains sixty-six nutrientseach for 3,404 foods. These nutrient data will be used for assessing intake data from WWEIA, NHANES 2013-2014. Nutrient profiles were added for 265 new foods and updated for about 500 foods from the version used for the previous survey (WWEIA, NHANES 2011-12).  New foods added include mainly commercially processed foods such as several gluten-free products, milk substitutes, sauces and condiments such as sriracha, pesto and wasabi, Greek yogurt, breakfast cereals, low-sodium meat products, whole grain pastas and baked products, and several beverages including bottled tea and coffee, coconut water, malt beverages, hard cider, fruit-flavored drinks, fortified fruit juices and fruit and/or vegetable smoothies. Several school lunch pizzas and chicken products, fast-food sandwiches, and new beef cuts were also added, as they are now reported more frequently by survey respondents. Nutrient profiles were updated for several commonly consumed foods such as cheddar, mozzarella and American cheese, ground beef, butter, and catsup. The changes in nutrient values may be due to reformulations in products, changes in the market shares of brands, or more accurate data. Examples of more accurate data include analytical data, market share data, and data from a nationally representative sample.

该数据集，名为Survey-SR，提供了源自美国全国性调查‘我们吃什么’（What We Eat In America，简称WWEIA）、国家健康与营养状况调查（National Health and Nutrition Examination Survey，简称NHANES）的营养数据。历史上，美国农业部（USDA）数据库一直被用于国家营养监测（1）。目前，食品营养调查研究小组（Food Surveys Research Group，ARS）采用食品与营养数据库（Food and Nutrient Database for Dietary Studies，简称FNDDS）来处理WWEIA、NHANES的膳食摄入数据。FNDDS中的营养值基于Survey-SR。在较早的出版物中，Survey-SR被称为‘主数据集’。早期版本的该数据集主要由小麦粉、糖、牛奶等商品类物品组成。然而，随着商业加工食品和餐厅食品消费量的增加以及国家营养监测数据应用方式的变化（1），许多商业加工食品和餐厅食品也被纳入Survey-SR。当前版本，即2013-2014年的Survey-SR，主要基于美国农业部国家标准参考营养数据库（USDA National Nutrient Database for Standard Reference，简称SR）第28版（2），包含3,404种食品的六十六种营养素。这些营养数据将被用于评估WWEIA、NHANES 2013-2014的摄入数据。为265种新食品添加了营养概要，并对上一调查版本（WWEIA、NHANES 2011-12）中约500种食品的营养概要进行了更新。新增的食品主要包括如多种无麸质产品、乳制品替代品、辣酱、意式青酱和山葵、希腊酸奶、早餐谷物、低钠肉类产品、全麦面食和烘焙产品，以及包括瓶装茶和咖啡、椰子水、麦芽饮料、硬 cider、果味饮料、强化果汁和水果或蔬菜奶昔在内的多种饮料。此外，还增加了几个学校午餐比萨、鸡肉产品、快餐三明治和新牛肉切片，因为它们现在在调查受访者中被报告得更为频繁。对于诸如切达干酪、马苏里拉干酪和美国干酪、牛肉、黄油和番茄酱等常见食品的营养概要也进行了更新。营养值的变动可能归因于产品配方调整、品牌市场份额变化或更精确的数据。更精确的数据示例包括分析数据、市场份额数据和全国代表性样本数据。本数据集中的资源包括：资源标题：美国农业部国家标准参考营养数据库数据集——‘我们吃什么’、NHANES 2013-14（Survey SR 2013-14）。文件名：SurveySR_2013_14（1）.zip资源描述：于2017年11月16日下载的数据库。美国农业部，农业研究服务局，营养数据实验室。美国农业部国家标准参考营养数据库数据集——‘我们吃什么’、NHANES（Survey-SR），2015年10月。资源标题：数据字典。文件名：SurveySR_DD.pdf
