Why do the numbers from a barcode scan not match my label?

Makers change recipes and serving sizes without changing the barcode. The USDA copy we hold is a snapshot taken on a date, not a live feed. Open Food Facts fills the gaps and is typed in by shoppers, not verified.

Food databases publish nutrition per 100 grams, and we convert that to the serving on the package. If a saved ingredient reads check the serving in My Ingredients, its numbers are for 100 grams. Open it to see the figures for your serving and correct it in one tap.

The label itself rounds. Calories go to the nearest five or ten, fat to half a gram, and sodium under 5 mg prints as 0, so an exact match is not always possible.

Always check a scanned food against the package and save your own version. Yours is the one we count.
