Ultra-processed food: what is really in it

Processing and additives: McDonald's US Big Breakfast

McDonald's US Big Breakfast is assembled from 6 separately manufactured components, combined and served at the point of sale. Reading the ingredient list closely, it contains dextrose, modified starches, emulsifiers, thickeners and gums, processed cellulose, flavourings, flavour enhancers, phosphates and raising agents, hydrogenated or interesterified oils and protein and dairy fractions. 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 browns and sausage patty.

Modified starches

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

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the biscuit.

Thickeners and gums

Thicken sauces, fillings and drinks and stop them separating. Found in the biscuit.

Processed cellulose

Plant fibre processed into a bulking, anti-caking or texturing agent. Found in the biscuit.

Flavourings

Add or restore taste lost during processing. Found in the biscuit, hash browns and sausage patty.

Flavour enhancers

Boost savoury taste so less of the underlying ingredient is needed. Found in the hash browns.

Phosphates and raising agents

Hold moisture in meat, control acidity or make batters and doughs rise. Found in the biscuit and hash browns.

Hydrogenated or interesterified oils

Industrially hardened fats used for stability and frying life. Found in the hash browns.

Protein and dairy fractions

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

Boone classifies McDonald's US Big Breakfast 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.

Frequently asked questions

How many calories are in a McDonald's US Big Breakfast?+

The Dietary Guidelines for Americans, 2025–2030 recommend no added sugar for children aged 10 and under and no more than 10g per meal from age 11. With 1g of added sugar, McDonald's US Big Breakfast fits the per-meal limit for ages 11 and up but not the guidance for younger children.

How much saturated fat is in a McDonald's US Big Breakfast?+

Is McDonald's US Big Breakfast ultra-processed?+

Boone classifies McDonald's US Big Breakfast as NOVA group 4. Reading the published ingredient list, it is assembled from 6 separately manufactured components and contains dextrose, modified starches, emulsifiers, thickeners and gums, processed cellulose, flavourings, flavour enhancers, phosphates and raising agents, hydrogenated or interesterified oils and protein and dairy fractions. NOVA group 4 describes how far a food is from its whole-food form, not how nutritious it is.

How much fibre is in a McDonald's US Big Breakfast?+

McDonald's US Big Breakfast contains 3g of fibre. Boone calculates that as 11% of the 28g Daily Value and 14% of the 21g target for a child aged 4 to 8. Fibre is a target to reach rather than a limit to stay under.

Is McDonald's US Big Breakfast suitable for children?+
