Why is STACKZ Sour Cream & Onion flavour potato snacks classified as ultra‑processed (NOVA 4) and which additives does it contain?

The snack is made from processed potato flakes, refined oils, flavor powders and several isolated ingredients, which places it in the ultra‑processed NOVA 4 category. It contains additives including citric acid (E330), malic acid (E296), mono‑ and diglycerides of fatty acids (E471) and monosodium glutamate (E621) as flavor enhancer.

How do the sugar and salt levels in this snack affect people managing diabetes or hypertension?

With 4.3 g of sugar per 100 g, the snack can raise blood glucose and should be consumed sparingly by diabetics. The 1.28 g of salt contributes about 5 % of the recommended daily sodium limit, which may be acceptable in moderation but is less suitable for strict low‑salt hypertension diets.

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

The snack is not vegan because it contains milk‑derived ingredients such as sour cream powder, whey and lactose. It includes wheat starch, so it is not gluten‑free. The high carbohydrate content (58.3 g of carbs per 100 g) makes it unsuitable for a keto diet, and the presence of dairy may prevent it from being considered halal for some consumers.
