Boone calculates these percentages from McDonald's UK published nutrition data against UK Dietary Reference Values and NHS free sugar and salt limits. Free sugar, salt, calories and saturated fat are limits to stay under; fibre is a target to reach, so a high percentage there is a good thing. For guidance only.

Ultra-processed food: what is really in it
Processing and additives: McDonald's Big Mac Sauce
McDonald's Big Mac Sauce is assembled from 1 separately manufactured component. Reading the ingredient list closely, it contains firming agents, flavourings, glucose or glucose-fructose syrup, modified starches, stabilisers and thickeners. These are not there to add nutritional value. They make industrial production and distribution possible.
Firming agents
Keep processed vegetables crisp after packing. Found in the Big Mac sauce.
Flavourings
Add or restore taste lost during processing. Found in the Big Mac sauce.
Glucose or glucose-fructose syrup
Sweeten and control texture more cheaply than sugar alone. Found in the Big Mac sauce.
Modified starches
Thicken and hold water in a way unmodified flour cannot. Found in the Big Mac sauce.
Stabilisers
Stop mixtures separating and hold texture during storage and transport. Found in the Big Mac sauce.
Thickeners
Give sauces and syrups the body they would otherwise lack. Found in the Big Mac sauce.
Boone classifies McDonald's Big Mac Sauce 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. Read from the published ingredient list, 17-18 August 2026.
A McDonald's Big Mac Sauce contains at least 10 distinct ingredients: 7 raw and 3 manufactured.

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.
