About this food

Understanding this nutrition reference

Swordfish is a large, predatory saltwater fish known for its dense, meaty flesh and mildly rich flavor. Its firm steaks hold up well to high-heat cooking methods such as grilling, broiling, and pan-searing, and it is often compared to steak in both texture and versatility.

Nutritionally, swordfish is a good source of protein and supplies heart-healthy fats along with B vitamins, selenium, and other minerals. Because it is more substantial than many white fish, a modest portion is often enough to make a satisfying, protein-rich meal.
