Food data guide

USDA vs Open Food Facts.

DailyLabel uses two food-data sources because grocery items and whole foods are different problems. USDA FoodData Central is strong for standard foods. Open Food Facts helps with packaged foods and barcodes.

Last updated April 25, 2026. Values depend on source data and may vary.

DailyLabel USDA and Open Food Facts search results

USDA FoodData Central

Useful for many whole, raw, and standard foods. It is a public USDA database and often works well when you search by food name.

Open Food Facts

Useful for packaged-food and barcode lookup. It is an open product database, so coverage and completeness can vary by item.

Why DailyLabel uses both.

A private nutrition tracker should not force one source to do every job. DailyLabel can search foods by keyword, scan a barcode for free, and show source badges so you know where a result came from.

What to do when data is imperfect.

Food databases can disagree, serving sizes can be missing, and branded products can change. DailyLabel supports custom foods and editable food values so you can correct a result when it does not match the item in front of you.
