Boone classifies McDonald's Smarties McFlurry (Regular) as NOVA group 4, ultra-processed, based on the additives named above.

Boone counts every distinct named ingredient on McDonald’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 “stabiliser (guar gum)” counts guar gum once. 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. Where McDonald’s lists more than one approved supplier recipe only the primary one is counted, so every figure here is a minimum. The build uses a Sweet and Sour dip.
