Processing and additives: Burger King US Whopper Jr.

Burger King US Whopper Jr. is assembled from 9 separately manufactured components, combined and served at the point of sale. Reading the ingredient list closely, it contains dextrose, maltodextrin, emulsifiers, thickeners and gums, flavourings, phosphates and raising agents, firming agents, anti-foaming and anti-caking agents and protein and dairy fractions. These are not there to add nutritional value. They make industrial production and distribution possible.

Boone classifies Burger King US Whopper Jr. as NOVA group 4, ultra-processed, based on the additives named above. NOVA groups foods by how far they are from their whole-food form, not by how nutritious they are. A group 4 food is not automatically unhealthy, and a group 1 food is not automatically healthy.

What those ingredients are, by type

Boone counts every distinct named ingredient on Burger King’s published component lists, including sub-ingredients, and removes duplicates, so salt appearing in four components counts once. Additive class names are dropped and the named substance kept, so “leavening (baking soda)” counts baking soda once. Ice and water added at the counter are not counted. Raw covers whole foods and basic kitchen staples such as flour, sugar, salt and oil. Manufactured covers substances that only exist as an output of industrial processing. Every figure here is a minimum. The build uses a BBQ sauce.
