Percentages are the share of the FDA Daily Value for adults and children 4 and over, worked out from KFC’s published amounts (how % Daily Value works). A dash means KFC does not publish that value for this size.

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 fl oz size is high in carbohydrate (28%) and is low in sodium, cholesterol, dietary fiber and protein. Add it up with other items in the KFC nutrition calculator.

Allergens

KFC’s allergen information lists no allergen as an ingredient of the Dirty Pepsi. KFC’s information leaves milk unclear for this item (see the note below), so treat it as possibly present.

The allergen menu marks no allergens for this drink, but its published ingredient statement lists sodium caseinate (a milk derivative) in the vanilla crème.

KFC says its kitchens handle egg, milk, soy, wheat and other allergens, items can be prepared on shared equipment, and it cannot rule out cross-contact. In some restaurants fish, chicken and potatoes may share fryer oil. Several items contain or are cooked in highly refined soybean oil, which the FDA does not treat as an allergen. KFC does not use peanuts or tree nuts, but says the Café Valley chocolate chip and lemon cakes may contain traces of tree nuts. Vegetarian ingredients are handled alongside meat. Allergen data reflects standard recipes and may vary with suppliers, substitutions and recipe changes. MSG is reported alongside the allergens.
