USDA FoodData Central
Recipe math, done.
Build a recipe from USDA food records, enter the grams you actually use, and see the total and per-serving nutrition.
Add ingredients
This lookup sends each ingredient you search for to USDA FoodData Central (api.nal.usda.gov) from your browser. If you add your own data.gov key, it is sent to USDA too.
Recipe nutrition
Search for ingredients and add them to begin.
How the estimate works
Each ingredient is scaled from the USDA record's nutrient values per 100 grams. The calculator adds those scaled values, then divides by your serving count. Choose the closest matching food record and use the product label for branded foods when it is available.
Source: USDA FoodData Central. Records and nutrient values are updated by USDA over time.
Estimate, not medical guidance
Cooking, draining, water loss, recipe substitutions and brand differences can change the result. Do not use this calculator for allergy, clinical or therapeutic decisions.
