  1. Omega 3

    • Swordfish contain a rich supply of essential omega-3 oils. The omega-3 fatty acids are believed to help prevent various illnesses in humans including heart disease, heart attacks, clogged arteries, high blood pressure and rheumatoid arthritis. Dr. Donald Hensrud, chairman of the Division of Preventive Medicine at the Mayo Clinic, shared his views on the benefits of omega 3 from fish and a healthy heart. Fatty fish like the swordfish have omega-3 fatty acids that can enhance the immune system, decrease triglycerides and improve the cognitive function in growing children.

    Selenium

    • Swordfish contain micro-nutrients like selenium, an important antioxidant that plays a role in fighting caner and heart ailments. It serves as an essential mineral in maintaining the thyroid gland function. Selenium has a high binding affinity with mercury; when the two elements meet, they bind together and the selenium prevents the body from absorbing the mercury. Some experts believe that selenium helps to neutralize the mercury found in seafood and in other dietary sources.

    Vitamins

    • Fish are believed to be a good source of vitamins that help maintain strong teeth, bones, healthy nerve tissues and a healthy complexion. Swordfish contain B vitamins like vitamin B6, essential in the making of hemoglobin. This vitamin helps to increase the amount of oxygen carried by the blood, preventing anemia. B vitamins are also useful in converting food to energy. The swordfish is an oil-rich fish, a useful source of fat soluble vitamins A and D, both necessary for healthy bones.

    Minerals

    • Swordfish contain a variety of minerals including calcium, zinc, phosphorous, iron, fluoride and iodine. Calcium is beneficial in initiating the process of the DNA synthesis and for maintaining strong teeth and bones. Phosphorous assists in the release of energy from fats during metabolism, helps in the formation of cell membranes, enzymes and genetic material. Zinc boosts immunity assisting in blood formation, wound healing and tissue growth.
