Why is Mackerel in tomato sauce classified as ultra-processed (NOVA 4) and what specific additives does it contain?

The product is actually classified as NOVA 3, meaning it is processed but not ultra‑processed; it lists only sardines, concentrated tomato puree, sunflower oil, water and salt, with no added preservatives, flavourings or sweeteners.

How does the sugar and salt content in this product affect a diabetic or hypertensive diet?

At 2 g of sugar per 100 g, the product contributes a modest amount of carbohydrate that can fit into a diabetic meal plan when counted, while its extremely low salt (0.0015 g) makes it suitable for hypertension management.

Is the sardine component in this canned product a problem for people with fish allergies?

Yes; sardines are a fish ingredient and are declared as an allergen, so anyone with a fish allergy should avoid this product.
