title: US Food Nutrition Composition - USDA FoodData Central (Foundation + SR Legacy + FNDDS), full nutrient panels
description: Every food in USDA's authoritative composition databases with the amount of every nutrient it contains, in one clean long table - the join nobody wants to do by hand. FoodData Central ships this as five separate CSVs (food, food_nutrient, nutrient, food_category and a per-type NDB crosswalk); we assemble and de-duplicate them into one tidy (food × nutrient) Parquet. Covers the three pure-USDA bundles - Foundation Foods (analytically measured reference foods), SR Legacy (the classic ~7.8k-food Standard Reference that underpins US nutrition analysis) and FNDDS (the 'as consumed' survey foods people actually report eating) - with energy, macronutrients, vitamins, minerals, amino acids and fatty acids, each with its unit and amount per 100 g. A data_type column preserves the measured-vs-survey distinction so you can filter either way. Keyed by FDC id with the legacy NDB number carried through, so it joins to recipe, dietary-intake and agricultural data. Public domain (U.S. Government work).
