Ultra-processed food: what is really in it

Processing and additives: McDonald's Cheese & Bacon McCrispy

McDonald's Cheese & Bacon McCrispy is assembled from 6 separately manufactured components, combined and cooked at the point of sale. Reading the ingredient list closely, it contains acidity regulators, anti-caking agents, antioxidants, colours, dextrose, emulsifiers, flavourings, maltodextrin, modified starches, preservatives, raising agents, stabilisers and thickeners. 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 McCrispy patty.

Anti-caking agents

Stop powders and sliced products sticking together. Found in the processed cheddar cheese slice.

Antioxidants

Slow the natural oxidation of fats, so components keep their colour and flavour. Found in the sourdough bun, streaky bacon.

Colours

Restore or standardise appearance after processing. Found in the processed cheddar cheese slice.

Dextrose

A simple sugar used for browning, bulk and mild sweetness. Found in the sourdough bun.

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the sourdough bun, streaky bacon.

Flavourings

Add or restore taste lost during processing. Found in the sourdough bun, McCrispy patty, processed cheddar cheese slice.

Maltodextrin

Bulk out a product and carry flavour, with little taste of its own. Found in the sourdough bun, McCrispy patty.

Modified starches

Thicken and hold water in a way unmodified flour cannot. Found in the McCrispy patty.

Preservatives

Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the Black Pepper Mayo, streaky bacon.

Raising agents

Make doughs and batters rise without a long ferment. Found in the McCrispy patty.

Stabilisers

Stop mixtures separating and hold texture during storage and transport. Found in the sourdough bun, Black Pepper Mayo.

Thickeners

Give sauces and syrups the body they would otherwise lack. Found in the sourdough bun.

Boone classifies McDonald's Cheese & Bacon McCrispy 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 Cheese & Bacon McCrispy contains at least 45 distinct ingredients: 24 raw and 21 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.
