Ultra-processed food: what is really in it

Processing and additives: McDonald's US Strawberry Banana Smoothie (Large)

McDonald's US Strawberry Banana Smoothie (Large) is assembled from 2 separately manufactured components, combined and served at the point of sale. Reading the ingredient list closely, it contains modified starches, thickeners and gums, processed cellulose, flavourings, colours, protein and dairy fractions and demineralised juice. These are not there to add nutritional value. They make industrial production and distribution possible.

Modified starches

Starches altered industrially to thicken, bind or hold texture through freezing and reheating. Found in the lowfat smoothie yogurt.

Thickeners and gums

Thicken sauces, fillings and drinks and stop them separating. Found in the strawberry banana fruit base.

Processed cellulose

Plant fibre processed into a bulking, anti-caking or texturing agent. Found in the strawberry banana fruit base.

Flavourings

Add or restore taste lost during processing. Found in the strawberry banana fruit base.

Colours

Restore or standardise appearance after processing. Found in the strawberry banana fruit base.

Protein and dairy fractions

Isolated proteins and dairy by-products used to add bulk, structure or a creamy texture. Found in the lowfat smoothie yogurt.

Demineralised juice

Juice stripped of most of its flavour and minerals so it works as a sugar syrup. Found in the strawberry banana fruit base.

Boone classifies McDonald's US Strawberry Banana Smoothie (Large) 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, September 2026.

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 “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 Sweet ’n Sour sauce.
