Ultra-processed food: what is really in it
Processing and additives: Five Guys Little Bacon Burger
Five Guys Little Bacon Burger is assembled from 3 separately prepared components, combined and cooked at the point of sale. Reading the ingredient list closely, it contains acidity regulators, antioxidants, emulsifiers, flour treatment agents, preservatives, protein isolates and stabilisers. These are not there to add nutritional value. They make industrial production and distribution possible.
Acidity regulators
Control acidity so colour, flavour and shelf life stay stable. Found in the burger bun, bacon.
Antioxidants
Slow the natural oxidation of fats, so components keep their colour and flavour. Found in the bacon.
Emulsifiers
Help oil-based and water-based ingredients blend and stay blended. Found in the burger bun.
Flour treatment agents
Strengthen dough so it rises evenly on an industrial line. Found in the burger bun.
Preservatives
Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the bacon.
Protein isolates
Proteins extracted and concentrated from whole foods, used to add protein or improve texture. Found in the burger bun.
Stabilisers
Stop mixtures separating and hold texture during storage and transport. Found in the bacon.
Boone classifies Five Guys Little Bacon Burger as NOVA group 4, ultra-processed, based on the additives named above.

Boone counts every distinct named ingredient on Five Guys’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 (xanthan gum)” counts xanthan gum once. Vitamins and minerals added to flour by law 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.
