Colours

Restore or standardise appearance after processing. Found in the watermelon mix-in.

Dextrose

A simple sugar used for browning, bulk and mild sweetness. Found in the Five Guys milkshake base.

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the Five Guys milkshake base, whipped cream.

Flavourings

Add or restore taste lost during processing. Found in the Five Guys milkshake base, watermelon mix-in.

Preservatives

Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the watermelon mix-in.

Propellants

Stabilisers

Stop mixtures separating and hold texture during storage and transport. Found in the Five Guys milkshake base, whipped cream.

Boone classifies Five Guys Watermelon Shake 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 in the Five Guys UK allergen, ingredient and nutrition guide (5 August 2026).

A Five Guys Watermelon Shake contains at least 21 distinct ingredients: 9 raw and 12 manufactured. Raw means something you could buy and cook with at home; manufactured means a substance that only exists as an output of industrial processing.

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.
