Food and Nutrient Database for Dietary Studies (FNDDS)

[Note: Integrated as part of FoodData Central, April 2019.]
USDA's Food and Nutrient Database for Dietary Studies (FNDDS) is a database that is used to convert food and beverages consumed in What We Eat In America (WWEIA), National Health and Nutrition Examination Survey (NHANES) into gram amounts and to determine their nutrient values. Because FNDDS is used to generate the nutrient intake data files for WWEIA, NHANES, it is not required to estimate nutrient intakes from the survey. FNDDS is made available for researchers using WWEIA, NHANES to review the nutrient profiles for specific foods and beverages as well as their associated portions and recipes. Such detailed information makes it possible for researchers to conduct enhanced analysis of dietary intakes. FNDDS can also be used in other dietary studies to code foods/beverages and amounts eaten and to calculate the amounts of nutrients/food components in those items.

FNDDS is released every two-years in conjunction with the WWEIA, NHANES dietary data release. The FNDDS is available for free download from the FSRG website.

美国农业部（United States Department of Agriculture, USDA）下属的膳食研究用食品与营养数据库（Food and Nutrient Database for Dietary Studies, FNDDS）可用于将美国饮食摄入情况调查（What We Eat In America, WWEIA）与美国国家健康与营养检查调查（National Health and Nutrition Examination Survey, NHANES）中记录的食用食品与饮料转换为克重，并测算其营养成分数值。由于FNDDS用于生成WWEIA与NHANES的营养摄入数据文件，因此无需再通过调查数据估算营养摄入量。该数据库面向使用WWEIA、NHANES数据的研究人员开放，供其查询特定食品、饮料的营养概况，以及对应的食用分量与食谱信息。此类详尽的信息可支持研究人员开展精细化的膳食摄入数据分析。FNDDS还可应用于其他膳食研究，用于对食用的食品/饮料及其摄入量进行编码，并计算对应食品中营养成分与膳食组分的含量。

FNDDS每两年与WWEIA、NHANES的膳食数据同步发布。研究人员可从食品调查研究组（Food Surveys Research Group, FSRG）的官方网站免费下载该数据库。
