Tuna fillet is one of the most prized parts of the fish, with a soft texture and intense flavor. It is often used in cooking to prepare raw or lightly cooked dishes. Tuna is a very versatile fish and can be cooked in different ways, such as grilled, baked or stewed. Tuna is rich in protein and omega 3, it is a source of vitamin B12 and vitamin D. It is a fish that can be found fresh, preserved in oil, salted or canned. Fresh tuna fillet is the most valuable and is generally used to prepare raw dishes such as sushi and carpaccio. Canned tuna, on the other hand, is cheaper and is used to prepare cooked dishes such as tuna pasta or for salads.
