USDA FoodData Central • SR Legacy • FDC ID Lookup
USDA SR Legacy Nutrition Facts Database by FDC ID
Search source-linked nutrition facts by food name, nutrient, or exact FDC ID. Each lookup path is designed around record identity, per-100 g comparison, label interpretation, and practical macro planning.
Dataset manifest
Source-bound nutrition data, built for comparison
Use eNutritionFacts to check a food record, compare values on a common serving basis, and continue into practical tools when a static nutrition table is not enough.
- Food records
- 7,793 SR Legacy foods
- Nutrient dimensions
- Up to 150 food components
- Primary identifier
- USDA FoodData Central FDC ID
- Serving basis
- Per 100 g edible portion
Why this database is different
Nutrition facts with source identity, not anonymous numbers
Use eNutritionFacts when you need more than a calorie estimate: check the source record, compare foods on the same 100 g basis, and move from lookup into practical macro or meal-planning workflows.
Record-first lookup
Food pages are organized around identifiable records, food names, and FDC IDs instead of generic nutrition summaries.
Per-100 g comparison
Compare foods on a consistent basis before deciding whether a serving, recipe, or label claim is meaningful.
Methodology visible
Source notes, serving basis, limitations, and update logic are linked so users can understand where values come from.
Planning layer
When a static value is not enough, interactive tools help translate nutrition facts into daily targets and meal ideas.
Atomic nutrition claims
Featured USDA-linked nutrition profiles — per 100 g
Start with a quick per-100 g comparison, then open the full profile when you need source identity, serving context, and deeper nutrient detail.

Quick answers
How to use eNutritionFacts
Start with source-backed food lookup, then use guides and tools when you need label context, serving interpretation, or practical planning.
What is eNutritionFacts based on?
It structures nutrition facts around USDA FoodData Central SR Legacy food composition records and FDC identifiers.
Why use FDC IDs?
FDC IDs help connect a nutrition profile to a specific source record instead of relying only on a broad food name.
Why per 100 g?
A per-100 g basis makes foods easier to compare before adjusting for serving size, recipe quantity, or personal targets.
