Free sugar vs total sugar

Where the sugar comes from: Papa John's Vegan Garden Party Authentic Thin Crust pizza

All 43g 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 10.8 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 Vegan Garden Party Authentic Thin Crust pizza

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

Papa John's Vegan Garden Party Authentic Thin Crust pizza is assembled from 8 components. Papa John's names each topping and the allergens in each component, but it does not publish full ingredient lists for its dough, sauces, cheese or toppings, so Boone cannot count ingredients or additives.

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.
