Open Data

Free Nutrition Database — CSV & API (Public Domain)

We publish nutrition data for 60,000+ foods based on USDA FoodData Central as open data. USDA's raw release spans a dozen relational CSV files; ours is consolidated into one flat, analysis-ready CSV plus a free JSON API. Public domain (CC0) — free for commercial and non-commercial use, no attribution required.

License: Public Domain (CC0)

The underlying data, USDA FoodData Central, is released by the U.S. Department of Agriculture into the public domain. Everything NutriDB adds on top (category mapping, summaries, Daily Value percentages) is likewise provided under CC0. You don't need to ask permission or credit us — though a link back to NutriDB (nutri-db.com) is always appreciated.
