Food Composition


Where can I get information on the levels of calories, fat, protein, vitamins and minerals in various foods?

Visit FNIC's Food Composition section for lists of where nutrients are found in food. To find the nutrient content of specific foods, USDA's FoodData Central is an integrated data system that provides expanded nutrient profile data and links to related agricultural and experimental research.

Where can I find information on trans fats, and how I can I tell if certain foods have them?

The trans fat content of a food item can be found by searching for the food item in the USDA's FoodData Central. Please note that the trans fat content is provided only if the food item contains trans fat. You can find an abridged list of trans fat sources on the USDA Nutrient Lists from Standard Reference Legacy (2018). 

Where can I find how much omega-3 and omega- 6 fatty acids are in different foods?

FoodData Central contains five distinct types of data containing information on food and nutrient profiles, each with a unique purpose. Two of the data types—Foundation Foods and Experimental Foods—have never previously been available. Foundation Foods provides nutrient values and extensive underlying metadata on foods available to the U.S. consumer; Experimental Foods link to relevant agricultural research data from multiple sources.

Is the USDA Database for the Added Sugars Content of Selected Foods still available?

The USDA NDL has removed the USDA Database for the Added Sugars Content of Selected Foods from the NDL website. This is due to constant changes in formulations for commercial, multi-ingredient foods, the primary contributor of added sugars to the diet. NDL is not recalculating added and intrinsic sugars at this time, in part, because brand name market shares and ingredients are changed so rapidly that these estimates are more a temporary cross-section in time than fixed values.
