Search Foods
Search 7,793 foods for complete nutrition facts. 2,000 curated with 113 nutrients from 3 databases.
About the Food Database
The Human Nutrition Explorer indexes 7,793 foods from the USDA FoodData Central database, the most widely cited food composition resource in nutrition science. Of these, 2,000 foods have been individually curated with full nutrient profiles harmonized from three independent databases: USDA Foundation Foods, the Australian Food Composition Database (AFCD), and USDA SR Legacy.
Each curated food page includes up to 113 individual nutrients — from standard macronutrients and vitamins to detailed amino acid profiles, fatty acid breakdowns (including omega-3 EPA, DHA, and ALA), carotenoids (beta-carotene, lycopene, lutein), vitamin K sub-forms (K1 and K2), vitamin D sub-forms (D2 and D3), and bioactive compounds like polyphenols and flavonoids.
Beyond raw nutrient data, curated food pages also feature glycemic index and glycemic load estimates, insulin index values, nutrient density scores (NRF9.3), environmental impact data from Poore & Nemecek (2018), nutrient synergies, and an FAQ section — making them among the most detailed food nutrition pages available online.
How to Use the Search
The search bar supports several types of queries to help you find exactly what you need:
- Search by food name — Type any food (e.g., "salmon", "sweet potato", "chickpeas") to find matching results from the full database.
- Search by nutrient — Type a nutrient name like "vitamin C", "iron", "omega 3", or "zinc" to find foods rich in that nutrient.
- Search by dietary goal — Try queries like "high protein", "low sodium", "high fiber", or "low calorie" to filter by nutritional properties.
- Food group filter — Use the dropdown to narrow results to a specific USDA food group such as Vegetables, Beef Products, Dairy, Legumes, or Finfish and Shellfish.
- Sort options — Sort results by relevance, name, calories, protein, fiber, fat, sodium, or nutrient density score to find the best matches for your needs.
Toggle "Curated only" to limit results to the 2,000 foods with complete multi-database nutrient profiles. These curated entries have the most comprehensive data, including amino acid and fatty acid breakdowns, environmental impact, and glycemic response data.
What Does "Curated" Mean?
The 2,000 curated foods were selected to represent the most commonly consumed whole foods, ingredients, and staples worldwide. Each curated food has been individually reviewed and enriched with data from multiple sources:
- USDA Foundation Foods — Gold-standard analytical data with detailed nutrient profiles measured in controlled laboratory settings.
- Australian Food Composition Database (AFCD) — An independent database from Food Standards Australia New Zealand (FSANZ) that provides additional nutrient values and cross-validation.
- USDA SR Legacy — The historic Standard Reference database containing decades of food composition data for thousands of food items.
Where data conflicts exist between sources, the harmonization process prioritizes Foundation Foods (analytically determined values), then cross-references with AFCD, and falls back to SR Legacy. This three-database approach produces more robust and complete nutrient profiles than any single source alone.
Food Groups Covered
The database includes foods from all 25 USDA food groups, spanning every major category of the human diet:
Each food is assigned to exactly one primary USDA food group. Use the food group dropdown filter above to browse all foods within a specific category, or combine it with search terms for targeted results.
Data Sources & Methodology
All nutrient data originates from government food composition databases that follow internationally standardized analytical methods. The primary source is USDA FoodData Central, maintained by the U.S. Department of Agriculture's Agricultural Research Service. Nutrient values are determined through laboratory analysis of representative food samples, not estimated or calculated.
Supplementary data layers include glycemic index estimates from the University of Sydney's GI Database, insulin index values modeled from published research (including both directly measured values and estimates from macronutrient composition), environmental impact data from Poore & Nemecek's meta-analysis of ~38,700 farms across 119 countries, and nutrient density scores calculated using the NRF9.3 algorithm developed by Fulgoni et al.
All data is provided under open licenses (CC0 for USDA data, CC BY 4.0 for AFCD data) and is freely available for educational and research purposes. For data sources and methodology, visit the Press & Methodology page.

Frequently Asked Questions
How accurate is the nutrient data?
The nutrient data comes from laboratory analyses published by the USDA and FSANZ. These are the same databases used by hospitals, dietitians, and academic researchers worldwide. However, all food composition data has inherent variability — nutrient content varies by growing conditions, season, variety, preparation method, and storage. The values represent typical compositions for each food as normally consumed.
Why are there 7,793 total foods but only 2,000 curated?
The full database of 7,793 foods includes every entry from USDA FoodData Central with basic nutrient data (calories, protein, fat, carbohydrates). The 2,000 curated foods have been individually selected and enriched with complete profiles from three databases, additional data layers (glycemic index, insulin index, environmental impact), and detailed sub-nutrient breakdowns. Curation is ongoing, and new foods are added regularly.
What are the 113 nutrients tracked for curated foods?
The 113 nutrients include: energy, water, protein, total fat, carbohydrates, fiber, sugars; 13 vitamins (A, C, D2, D3, E, K1, K2, B1, B2, B3, B5, B6, B12, folate, choline); 11 minerals (calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, copper, manganese, selenium, fluoride); 18 amino acids; 20+ individual fatty acids (including saturated, monounsaturated, polyunsaturated, trans, EPA, DHA, ALA); carotenoids (beta-carotene, alpha-carotene, lycopene, lutein+zeaxanthin, beta-cryptoxanthin); and additional bioactive compounds where data is available.
What is the nutrient density score?
Curated foods include an NRF9.3 (Nutrient Rich Foods 9.3) score, an evidence-based index developed by Fulgoni et al. (2009). It sums the percentage of Daily Value for 9 nutrients to encourage (protein, fiber, vitamins A, C, E, calcium, iron, magnesium, potassium) and subtracts 3 nutrients to limit (saturated fat, added sugars, sodium), all calculated per 100 kcal. Higher scores indicate more nutritious foods relative to their calorie content.
Can I use this data for my research or publication?
Yes. The underlying USDA data is public domain (CC0), and the AFCD data is available under CC BY 4.0. You are free to use, share, and adapt the data for any purpose, including commercial use, provided you give appropriate credit for AFCD-sourced data. Please cite the Human Nutrition Explorer and the original databases when using this data in publications or projects.
How does the search ranking work?
The search uses fuzzy matching powered by Fuse.js, which ranks results by relevance based on how closely a food name matches your query. When you search for nutrient-related terms (like "high protein" or "vitamin C"), the system switches to nutrient-based ranking, showing foods with the highest values for that nutrient first. The "Curated only" toggle further prioritizes foods with the most complete data profiles.
