Horse mackerel is a healthy fish that provides a good balance of protein and healthy fats. It is rich in omega-3 fatty acids (EPA and DHA), which protect the heart, support brain function, and lower inflammation. Horse mackerel also contains important vitamins like B12 and D, and minerals such as selenium, iodine, and phosphorus that help with strong bones, healthy blood, and thyroid function. Compared to oily fish like regular mackerel, horse mackerel is slightly leaner and lower in calories, making it a wholesome option for a balanced diet.
