About these numbers
USDA FoodData Central describes this record as “McDONALD'S, BIG MAC” (FoodData Central SR Legacy 2018-04). It is a laboratory analysis of the item as USDA sampled it, not the menu data a company publishes today. SR Legacy was closed in 2018 and is not updated, so the figures are a snapshot.
Restaurants change recipes, suppliers and portion sizes, and the item you order can differ from the one USDA sampled. For the current figures, use the nutrition information McDonald's publishes itself. Use this page to estimate, not to settle an allergy or a medical question.
USDA reported 23 of the 31 nutrients this page tracks for the record; the rest show as “Not reported”.
