Free sugar vs total sugar

Where the sugar comes from: Papa John's Lemon Cheesecake

All 27g counts as free sugar. Papa John's does not separate naturally occurring sugar from added sugar, so Boone counts the full figure. Sugars from tomato sauce, BBQ sauce, honey drizzles, dough and added sugar are free sugars; any from whole vegetables, pineapple or cheese would not be, so this may slightly overstate it. That is 6.8 teaspoons.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6.

Ultra-processed food: what is really in it

Processing: Papa John's Lemon Cheesecake

Boone cannot classify this item, because Papa John's does not publish full ingredient lists for its dough, sauces, cheese or toppings.

NOVA classification is read from an ingredient list. Papa John's names the toppings on each item and the allergens in each component, which is more than many chains publish, but that is not enough 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 Papa John's does publish a full list (its wheat-free base, its sourdough base and its vegan Sheese) it is shown in the ingredients section above.

Ingredients

Ingredients: Papa John's Lemon Cheesecake

Papa John's does not publish an ingredient list for Lemon Cheesecake, and it is under no legal obligation to do so.

Food made to order 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. A full ingredient list is voluntary, so Boone cannot count the ingredients in this item or say how many are manufactured.

Allergen information for this item is published by Papa John's and is shown below. Recipes change, so always check with the store before ordering if you have an allergy.

Contains = declared by Papa John's as an ingredient allergen. May contain traces = Papa John's or its supplier flags a risk of cross contact. Papa John's makes food by hand in stores that handle milk and wheat, and all pizzas and many sides pass through shared ovens and equipment, so it cannot guarantee any item is free from any allergen, including its wheat-free base, which is not suitable for coeliacs.
