Ultra-processed food: what is really in it

Processing: Slim Chickens Oreo Shake

Boone cannot classify this item, because Slim Chickens does not 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.

Classification is based on published ingredient lists only. If Slim Chickens publishes one, this section will be updated.

Ingredients

Slim Chickens does not publish an ingredient list on its allergen and nutrition menu

Ingredients: Slim Chickens Oreo Shake

The Slim Chickens UK allergen and nutrition menu gives nutrition figures for a Slim Chickens Oreo Shake but no ingredients, and the chain is under no legal obligation to publish them.

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.

Without an ingredient list, 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.

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