Why is Atún claro al natural bajo en sal classified as ultra‑processed (NOVA 4) and what specific additives does it contain?

The NOVA‑4 label reflects that the tuna is not sold plain but is reconstituted with added water and a natural flavouring, which are considered formulation steps beyond simple canning; no other additives such as preservatives are listed, but the presence of these ingredients moves it into the ultra‑processed category.

How does the salt content in this canned tuna affect a low‑sodium or hypertensive diet?

With 0.16 g of salt per 100 g, the product provides roughly 0.4 % of the daily recommended maximum of 5 g, making it a low‑salt choice that can fit into a sodium‑controlled diet, though total intake should still be monitored if other salty foods are consumed.

Can this tuna be considered suitable for vegan or vegetarian diets?

No. The primary ingredient is yellowfin tuna, a fish, which makes the product non‑vegan and non‑vegetarian, and it also carries a fish allergen warning.
