Why is TUNNOCK'S classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The biscuits are made from refined sugars, glucose syrup, condensed milk, palm oil and multiple emulsifiers, which are characteristic of ultra‑processed foods. The label lists soy lecithin (E322) as an emulsifier and a flavouring ingredient; these are the main additives identified.

How does the sugar and saturated fat content in TUNNOCK'S affect a diabetic or hypertensive diet?

With 34.7 g of sugar per 100 g, the product can cause rapid spikes in blood glucose, making it unsuitable for tight diabetic control. The saturated fat level of 12.7 g per 100 g contributes to higher LDL cholesterol, which may raise blood pressure and cardiovascular risk for hypertensive individuals.

Based on the ingredients, is this product suitable for strict diets like vegan, keto, halal, or gluten‑free?

No. It contains milk and sweetened condensed milk, so it is not vegan or halal for those avoiding dairy. The presence of wheat flour in the emulsifier blend makes it unsuitable for gluten‑free diets, and the high carbohydrate and sugar content means it does not fit a keto profile.
