Pacific Cod and Atlantic Cod Health Benefits

Omega-3 Fatty Acids

Atlantic cod contains 50% approximately more omega-3s than Pacific cod. Why does omega-3 fatty acids matter so much? Omega-3 fatty acids are heart healthy and help keep arteries healthy. One way they accomplish this is by keeping bad cholesterol low and good cholesterol high.

Two of the fatty acids, DHA and EPA are associated with lowering blood pressure and improving the health of blood vessels 3.

Also, they help keep the blood vessels healthy by reducing inflammation, plaque build-up, triglycerides and can help keep the heart rhythms more normal.

Many studies suggest omega-3s can help reduce joint pain and stiffness in people with rheumatoid arthritis. They may also boost the effectiveness of anti-inflammatory drugs.
