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, the 20 Oz size is low in sodium, fat, saturated fat, cholesterol, carbohydrate, dietary fiber and protein. Add it up with other items in the Papa Johns nutrition calculator.
Allergens
The Diet Dr Pepper is not in Papa Johns’ allergen information, so this site has no allergen information for it. That does not mean it is free of allergens: ask the restaurant before ordering if you have a food allergy.
Papa Johns says most of its menu is made to order and it cannot guarantee any item is free of the major allergens because of possible cross-contact in its kitchens, and it takes no responsibility for guests with food allergies. Its chart covers the nine major allergens; per-item flags in "May contain" combine two marks the chain uses: produced or stored in a facility that handles the allergen, and may contain or made on the same production lines. The information is based on its standard U.S. recipes, and recipes, ingredients and suppliers can change.
