Source-backed nutrition facts — USDA food data, labels, and comparison tools
Look up nutrition facts by source record, compare foods per 100 g, decode food labels, and trace every value back to its USDA FoodData Central context before using it in guides, articles, or everyday decisions.
About this database
Nutrition data with source traceability, not anonymous calorie estimates
eNutritionFacts is designed for readers who want to know where a nutrition value comes from before using it. Food profiles and tools are built around source-linked records, especially USDA FoodData Central entries, so calories, macronutrients, serving context, and selected micronutrients can be traced back to a visible record identity.
The site emphasizes per-100 g comparisons because a common weight basis makes foods easier to compare before serving-size differences, preparation methods, or branded product labels are considered. When a food page includes a serving-size table, source note, brand owner, FDC ID, or last-checked date, those details help readers and editors understand the limits of the data rather than treating one value as universal.
Nutrition information here is educational. It can support food-label literacy, article research, and general comparison, but it is not a diagnosis, treatment plan, or personalized dietary prescription. Health-sensitive topics are routed through review-gated editorial workflows before they should be used as stronger guidance.

Why use eNutritionFacts
Food data, labels, and methodology in one place
Use eNutritionFacts when you need more than a calorie estimate: check the source record, compare foods on the same 100 g basis, learn label terms, and understand how values should be used cautiously.
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.
Reader-first tools
Interactive tools help readers move from food lookup to comparison, label interpretation, recipe analysis, and macro planning.

What is eNutritionFacts based on?
It uses source-linked food records, label explanations, editorial methods, and educational tools to make nutrition facts easier to verify and understand.
Why use FDC IDs?
FDC IDs help connect a nutrition profile to a specific USDA FoodData Central record instead of relying only on a broad food name.
Is this medical advice?
No. eNutritionFacts content is educational and informational only. Individual nutrition needs can vary and may require professional guidance.
