Atlantic mackerel outer meat is red meat while inner meat is white, with a strong taste desirable to some consumers. They are sold fresh, frozen, smoked, salted, filleted, or as steaks. The fish is extremely high in oil content, vitamin B, vitamin B, selenium, niacin, and omega 3, a class of fatty acids, containing nearly twice as much of the latter per unit weight as salmon. Unlike the King and Spanish species, Northern Atlantic mackerel are very low in mercury, and can be eaten at least twice a week according to United States Environmental Protection Agency guidelines.
