Using the FDA’s rule of thumb that 5% of the Daily Value or less per serving is low and 20% or more is high, one serving is low in sodium, protein, fat, saturated fat, cholesterol, carbohydrate and dietary fiber. Add it up with other items in the Whataburger nutrition calculator.

Allergens

Whataburger does not publish allergen information in its nutrition guide. It shows allergens only in its online ordering menu (on whataburger.com and in the Whataburger app), so this site has no allergen data for Whataburger items; check the ordering menu or ask the restaurant.
