Free sugar vs total sugar

Where the sugar comes from: Wingstop Lemon Pepper Sweet Potato Fries

Boone has not split this item's sugar. Wingstop Lemon Pepper Sweet Potato Fries contains ingredients whose sugars occur naturally, so not all of the 26.6g counts as free sugar. Publishing a free sugar figure here would overstate it.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6.

Ultra-processed food: what is really in it

Processing and additives: Wingstop Lemon Pepper Sweet Potato Fries

Wingstop Lemon Pepper Sweet Potato Fries is assembled from 3 separately manufactured components, combined and cooked at the point of sale. Reading the ingredient list closely, it contains acidity regulators, colours, flavourings, modified starches, 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 lemon pepper seasoning.

Colours

Restore or standardise appearance after processing. Found in the sweet potato fries.

Flavourings

Add or restore taste lost during processing. Found in the lemon pepper seasoning.

Modified starches

Thicken and hold water in a way unmodified flour cannot. Found in the sweet potato fries.

Raising agents

Make doughs and batters rise without a long ferment. Found in the sweet potato fries.

Stabilisers

Stop mixtures separating and hold texture during storage and transport. Found in the sweet potato fries.

Thickeners

Give sauces and syrups the body they would otherwise lack. Found in the sweet potato fries.

Boone classifies Wingstop Lemon Pepper Sweet Potato Fries 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, 22 September 2026.

A portion of Wingstop Lemon Pepper Sweet Potato Fries contains at least 28 distinct ingredients: 18 raw and 10 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 Wingstop'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. 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.
