Ultra-processed food: what is really in it
Processing and additives: McDonald's Banana Milkshake (Medium)
McDonald's Banana Milkshake (Medium) is assembled from 2 separately manufactured components, combined and cooked at the point of sale. Reading the ingredient list closely, it contains acidity regulators, colours, flavourings, glucose or glucose-fructose syrup, preservatives and stabilisers. These are not there to add nutritional value. They make industrial production and distribution possible.
Acidity regulators
Hold the ph steady so flavour and shelf life stay consistent. Found in the banana flavour milkshake syrup.
Colours
Restore or standardise appearance after processing. Found in the banana flavour milkshake syrup.
Flavourings
Add or restore taste lost during processing. Found in the banana flavour milkshake syrup.
Glucose or glucose-fructose syrup
Sweeten and control texture more cheaply than sugar alone. Found in the milkshake base, banana flavour milkshake syrup.
Preservatives
Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the banana flavour milkshake syrup.
Stabilisers
Stop mixtures separating and hold texture during storage and transport. Found in the milkshake base.
Boone classifies McDonald's Banana Milkshake (Medium) 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.

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.
