Why is Thon blanc au naturel classified as processed (NOVA 3) and what specific additives does it contain?

The product is placed in NOVA group 3 because it undergoes processing that adds salt and packs the fish in a brine solution; it contains no other additives, offering a simple ingredient list of white tuna, water and salt.

How does the salt content in this canned white tuna affect a hypertensive diet?

With 1 g of salt per 100 g, the tuna provides less sodium than many canned fish alternatives, but it still contributes to daily sodium intake, so people with hypertension should consume it in moderation and balance it with low‑salt foods.

Is the fish ingredient in Thon blanc au naturel a concern for people with fish allergies?

Yes, the product lists fish (Thunnus alalunga) as an ingredient and as a declared allergen, so anyone allergic to fish should avoid this tuna.
