Ultra-processed food: what is really in it

Processing: Subway Garlic Cheesesteak 6 Inch Sub

Boone cannot classify this item, because Subway 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.

Ingredients

Subway does not publish an ingredient list for this item

Ingredients: Subway Garlic Cheesesteak 6 Inch Sub

Subway’s September 2026 UK nutrition and allergen guides do not include an ingredient list for a Subway Garlic Cheesesteak 6 Inch Sub, and it is under no legal obligation to provide one.

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.

Without one, 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.

Subway publishes allergen information for each ingredient, and Boone uses it to build the allergen table below. Recipes change, so always check in restaurant before ordering if you have an allergy.

Allergens at a glance

Subway Garlic Cheesesteak 6 Inch Sub contains wheat, barley, soya, milk, mustard and gluten. It may contain traces of sesame.

Contains = declared as an ingredient. May contain traces = Subway’s suppliers say the allergen is present at the manufacturing site and there is a significant risk of cross-contamination. Subway publishes allergens by ingredient, not by finished item, so Boone builds this table from Italian White bread, the filling, and onion, cucumber and lettuce. Choosing a different bread, cheese or sauce changes the allergens. Food is freshly prepared in Subway kitchens where many allergens are handled, so Subway cannot guarantee any item is allergen free. Vegan items are made to vegan recipes but are not suitable for people with milk or egg allergies.
