USDA, Nutrient Data Laboratory

FoodData Central is an integrated data system that provides expanded nutrient profile data and links to related agricultural and experimental research.

The mission of the Methods and Application of Food Composition Laboratory (MAFCL) is to identify critical food composition needs for researchers, policymakers, food producers and consumers. MAFCL develops and maintains food composition databases for foods available in the United States; conducts research on the impact of the environment, production, and preparation on food composition and intake; and develops new and improved analytical methods.
