Ultra-processed food: what is really in it
Processing and additives: McDonald's Hash Brown
McDonald's Hash Brown is assembled from 1 separately manufactured component. Reading the ingredient list closely, it contains dextrose, raising agents and stabilisers. These are not there to add nutritional value. They make industrial production and distribution possible.
Dextrose
A simple sugar used for browning, bulk and mild sweetness. Found in the hash brown.
Raising agents
Make doughs and batters rise without a long ferment. Found in the hash brown.
Stabilisers
Stop mixtures separating and hold texture during storage and transport. Found in the hash brown.
Boone classifies McDonald's Hash Brown 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 Hash Brown contains at least 9 distinct ingredients: 6 raw and 3 manufactured. Ordered as a full meal with a dip and a dessert that reaches 41, of which 21 are 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 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.
