Why is oven‑baked cheese & onion flavour classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The snack is made from reconstituted potato flakes, refined starch and refined oils, and it includes a cheese‑and‑onion seasoning that adds dairy‑derived whey, emulsifiers (sunflower lecithin, E322), colourants (annatto, paprika extract – E160c) and acidity regulators (citric acid – E330, malic acid – E296). This combination of multiple industrial ingredients and processing steps places it in the ultra‑processed NOVA 4 category.

How does the sugar and salt content of these crisps affect a diabetic or hypertensive diet?

With 7.2 g of sugars per 100 g, the product can cause a rapid rise in blood glucose and should be limited by people managing diabetes. The 0.9 g of salt per 100 g is relatively low for snack foods, but regular consumption can still contribute to sodium intake, so hypertensive individuals should monitor portion size.

Is the cheese and whey used in this snack a concern for people with milk allergy?

Yes. The ingredient list includes cheese, whey permeate, whey protein, whey powder and a dried cheese component, all of which are derived from milk and are flagged as a milk allergen, so the product is not safe for anyone with a milk allergy.
