Why is Atum Posta ao Natural classified as NOVA 3 and what additives does it contain?

The product is placed in NOVA 3 because it is a canned fish that undergoes limited processing: the tuna is cooked, packed in water and a small amount of salt, and sealed in a metal can. No preservatives, flavor enhancers or other additives are listed, so the ingredient list consists solely of tuna, water and salt.

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

With 1.24 g of salt per 100 g, the tuna provides a moderate sodium level. People managing high blood pressure should monitor their overall daily salt intake and may want to limit consumption of this product or pair it with low‑salt foods to stay within recommended limits.

Is Atum Posta ao Natural suitable for keto, gluten‑free and other strict diets?

Yes, the tuna contains virtually no carbohydrates, making it compatible with a ketogenic diet, and it has no gluten‑containing ingredients, so it is safe for a gluten‑free regimen. It is not suitable for vegan or vegetarian diets because it is an animal protein source, but it fits most other low‑carb or high‑protein dietary plans.
