Ultra-processed food: what is really in it

Processing: KFC Large Signature Fries

Boone cannot classify this item, because KFC chooses not to publish an ingredient list for it.

NOVA classification is read from an ingredient list. Without one there is no way to count additives, separate raw ingredients from manufactured ones, or say whether an item is ultra-processed. Boone does not estimate a NOVA group, because a guess presented as a classification would be worse than saying nothing.

Ingredients

KFC chooses not to publish an ingredient list

Ingredients: KFC Large Signature Fries

KFC does not publish the ingredients in a KFC Large Signature Fries, and it is under no legal obligation to do so.

Food made to order in a restaurant counts as non-prepacked under UK food law. The legal requirement is to declare the 14 major allergens, and for large businesses in England to show calories at the point of choice. A full ingredient list is voluntary. Some chains publish one anyway. KFC does not.

This means no page on this site can tell you how many ingredients are in this item, how many of them are manufactured substances, or whether it is ultra-processed. Boone will not estimate any of it. That absence is KFC’s decision, not an omission on our part.

KFC is not unusual in this. UK law lets any chain serving food made to order skip ingredient labelling entirely, and the chains that publish do so by choice.

Allergen information for this item is published by KFC and is shown below. Recipes change, so always check in restaurant before ordering if you have an allergy.
