Filets de maquereaux

Filets de maquereaux are canned Atlantic mackerel fillets in a shallot‑based marinade, produced in Douarnenez, Brittany, and classified under the PNNS ‘Fish Meat Eggs’ (fish) group. The product delivers about 13 g of protein per 100 g with moderate fat and low sugar, but it contains 0.9 g of salt and a small amount of added sugar, resulting in a Nutri‑Score of C and a NOVA 3 rating, indicating a moderately processed food with both benefits and drawbacks. Sustainably sourced from the North‑East Atlantic (FAO zone 27) and bearing the MSC label, the canned fillets also include ingredients such as vinegars, extra‑virgin olive oil, sunflower oil, white wine, and corn starch, meaning it is not a simple whole‑food item.
