Ultra-processed food: what is really in it

Processing: Burger King Breakfast King

Boone cannot classify this item, because Burger King 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.

Where an item on this menu is a sealed branded product, a bottled soft drink or a tub of ice cream for example, the manufacturer’s own label is used and a NOVA group is given.

Ingredients

Burger King chooses not to publish an ingredient list

Ingredients: Burger King Breakfast King

Burger King does not publish the ingredients in a Burger King Breakfast King, 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. Burger King 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 Burger King’s decision, not an omission on our part.

Burger King 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 Burger King and is shown below. Recipes change, so always check in restaurant before ordering if you have an allergy.
