Why is Sandwich atún classified as ultra‑processed (NOVA 4) and which additives does it contain?

The sandwich is considered ultra‑processed because it includes many industrial ingredients such as preservatives (E‑282, E‑200, E‑202, E‑211), acidity regulators (E‑260, E‑330), stabilisers and thickeners (E‑415, E‑425, E‑466, E‑575, E‑1414), antioxidants (E‑306, E‑385), a colour extract (E‑100) and a flour‑treatment agent (E‑300). These additives are typical of highly formulated food products.

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

The sandwich provides 3 g of sugars per 100 g, which is below the average for sandwiches and generally acceptable for diabetes management, but it contains 1.21 g of salt per 100 g, a moderate level that can contribute to higher sodium intake and may need to be limited in a hypertensive diet.

Is the tuna in Sandwich atún a concern for people with fish allergies?

Yes, the product lists tuna as an ingredient and includes a fish allergen warning; individuals with fish allergies should avoid this sandwich, and they should also be aware of other allergens present such as egg, mustard, soy and gluten.
