Tell Me More about FoodData Central
- What is FoodData Central?
FoodData Central is an integrated data system that allows easy access to USDA’s existing food composition data and provides nutrient content information never before available. FoodData Central also provides access to sources of related agricultural, food, health, dietary supplement, and other information. Including all these data in one data system strengthens the ability of researchers, policymakers, and others to address vital nutrition and health issues.
- Why has USDA launched FoodData Central?
The food supply is constantly changing and evolving, with new products and formulations continuously introduced into the marketplace and other products being removed. Moreover, ingredients and raw agricultural products are also constantly changing. This has implications for research, product development, dietary advice, and food policy.
These changes in the food supply and the growing variety of uses for food data have created an urgent need for transparent and easily accessible information about the nutrients and other components of foods and food products.
FoodData Central is USDA’s response to this need. Future versions of FoodData Central will continue to respond to this need with expanded food and experimental data and additional functionality.
- What data are included in FoodData Central?
FoodData Central includes five data types. Two of these types, Foundation Foods and Experimental Foods, provide data that have never been available previously. The three other types are SR Legacy, the Food and Nutrient Database for Dietary Studies, and the USDA Global Branded Food Products Database. Each of these data types is unique and was developed to meet specific needs. For example, the data in the Food and Nutrient Database for Dietary Studies make it possible for researchers to conduct enhanced analyses of dietary intakes reported in the National Health and Nutrition Examination Survey.
- Foundation Foods is a new data type that includes nutrient values as well as extensive underlying metadata on commercially available foods, such as the number of samples, sampling location, date of collection, analytical approaches used, and if appropriate, agricultural information such as genotype and production practices. These data allow users to see the variability in the nutrient values provided. The enhanced clarity and transparency around the data on these foods represent the future of FoodData Central and the number of foods in this data type will grow over time.
- Experimental Foods currently links to relevant agricultural research data from multiple sources, such as the Agricultural Collaborative Research Outcome System (AgCROS). In the next version of FoodData Central, this data type will include information from multiple sources about foods that have been produced under experimental conditions and are not commercially available. The agricultural data in Experimental Foods will allow users to examine a range of factors, such as geography and agricultural practices used, that may affect the nutritional profiles of foods and resulting dietary intake.
- SR Legacy is the final release of the USDA National Nutrient Database for Standard Reference, which uses earlier approaches to determining nutrient profiles of foods in the marketplace. It provides a comprehensive list of values for nutrients and food components that are derived from analyses and calculations.
- Food and Nutrient Database for Dietary Studies contains data on the nutrient values and weights for foods and beverages reported in the What We Eat in America dietary survey component of the National Health and Nutrition Examination Survey.
- USDA Global Branded Food Products Database (Branded Foods) are data from a public-private partnership that provides values for nutrients in branded and private label foods that appear on the product label. Information in Branded Foods is received from food industry data providers, and USDA supports this data type by standardizing the presentation of the data.
FoodData Central also contains links to related external data, including:
- The Dietary Supplement Ingredient Database (DSID), developed by USDA in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) and other federal agencies, provides estimated levels of ingredients in dietary supplement product categories commonly sold in the United States. These statistically predicted estimates may differ from labeled amounts and are based on chemical analysis of nationally representative products.
- The Dietary Supplement Label Database (DSLD) contains information from the labels of approximately 76,000 dietary supplement products available in the U.S. marketplace. In addition to a list of the contents and other added ingredients (such as fillers, binders, and flavorings), the DSLD includes information such as directions for use, health-related claims, and cautions. This database is developed by NIH Office of Dietary Supplements and is hosted by the National Library of Medicine.
- How are the nutrient values in FoodData Central derived?
The food composition values in FoodData Central are derived through a variety of analytic and computational approaches, using state-of-the-art methodologies and transparent presentation. For more information on how the values are derived for each data source, see Data Type Documentation.
- Can I use FoodData Central to access the food composition databases I’ve used before?
Yes. FoodData Central is an easy-to-access system that incorporates SR Legacy, the Food and Nutrient Database for Dietary Studies, and the USDA Global Branded Food Products Database. Users can use FoodData Central’s filter function to tailor their searches to one or more of these data types. Downloads are available for each of these data types.
- How is FoodData Central different from the existing USDA databases I have been using to access food composition data?
All of USDA’s major sources of food and nutrient data are now in one place, making them easy to access and use. FoodData Central’s Foundation Foods data also now provide expanded information on a growing number of foods, allowing users access to the data underlying the nutrient values. Additionally, FoodData Central provides links to relevant experimental data and other data sources, such as dietary supplement data.
By including these diverse types of data—food composition (FNDDS, Foundation Foods, and SR Legacy), branded food products (USDA Global Branded Food Products Database), dietary supplements, and experimental agricultural data—in one harmonized data system, FoodData Central contributes to the alignment of nutrient data with other key data systems, such as public health data, consumer data, sustainability and environmental data, and other nutrition and food databases. As a result, the ability of researchers, policymakers, and others to address vital nutrition and health issues can be enhanced.
- How do the data in FoodData Central accommodate the rapidly and everchanging U.S. food supply?
The food supply is constantly changing and evolving, with new products and formulations continuously introduced into the marketplace and other products being removed. Moreover, ingredients and raw agricultural products are constantly changing. This has implications for research, product development, dietary advice, and food policy.
FoodData Central data represent a broad snapshot in time of the nutrients and other components found in a wide variety of foods and food products. The data reflect the foods and analytic and computational techniques that were available at the time the foods were sampled and are updated as new information becomes available.
