NutrientsDB Sample Data

A small, representative sample from NutrientsDB, the global food composition database for developers, researchers, and AI builders.

The full database has 2.9M+ food entries across 86 nutrient fields, normalized to standard units and deduplicated across 180+ countries. This repo contains a tiny slice so you can inspect the shape of the data before getting the full dataset.

What's here

File	Description
sample.json	1,000 food entries with the complete 86-field nutrient schema

This mirrors the free 1,000-food sample available at nutrientsdb.com.

Github: https://github.com/colinearstudio/nutrientsdb-sample Hf: https://huggingface.co/datasets/colinearstudio/nutrientsdb

Working with the data

The data is plain JSON, so it loads in any language with no database server required.

import json

with open("sample.json") as f:
    foods = json.load(f)

for food in foods:
    n = food["nutrients"]
    print(food["name"], n["energy_kcal"], "kcal")

Data schema

Each record has a stable public_id, a human-readable name, and a nutrients object. All 86 nutrient keys are present on every entry. Values are numbers, or null when a source does not report that nutrient.

{
  "public_id": 2923506,
  "name": "Turkey, drumstick, from whole bird, meat only, raw",
  "nutrients": {
    "energy_kcal": 109.0,
    "protein_g": 23.66,
    "fat_g": 1.48,
    "carbs_g": 0.14,
    "vitamin_b12_ug": 0.63,
    "potassium_mg": 242.0
  }
}

All values are per 100 g of the food, the standard basis for food composition data.
