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. Not published for this item: added sugars.

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 12 fl oz size is low in sodium, fat, saturated fat, cholesterol, dietary fiber and protein. Add it up with other items in the KFC nutrition calculator.

KFC lists 0 g added sugars for every size of this item although it lists 39 to 98 g total sugars; this site leaves added sugars out.
