Although fish is high in minerals, it is a low-sodium food.

Sodium is a component of common table salt, something that many of us over-consume. The majority of salt in our diets comes from meat and meat products, such as pies and ready meals. Swapping a meat meal for a seafood meal could help people lower their salt intake.

Diets that contain too much salt have been linked to high blood pressure, strokes and heart disease.
