Why is Tonno al naturale classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The product is labeled NOVA 4 because industrial processing adds ingredients such as salt, water and a natural celery flavor; although no synthetic additives are listed, the added salt and flavoring are considered processing aids that trigger the ultra‑processed classification.

How does the salt content in this product affect a hypertensive diet?

With 1.1 g of salt per 100 g (≈0.44 g sodium), a typical 80 g portion provides about 0.9 g of salt, well below the recommended maximum of 5 g per day for most adults, making it acceptable for people with hypertension when eaten in moderation.

Is Tonno al naturale suitable for specific dietary patterns like vegan, keto, or gluten‑free?

The product is not vegan or vegetarian because it contains tuna, but it is suitable for pescatarian, low‑carb and ketogenic diets due to its high protein and negligible carbohydrate content, and it is naturally gluten‑free and contains no added sugars.
