Seal Oil

Seal Oil?

Interest in seal oil as a source of long-chain Omega-3 fatty acids began some thirty years ago. The remarkable studies on the dietary consumption of Greenland Eskimos by Danish scientists Bang and Dyerberg marked the beginning of long-chain Omega-3 fatty acids being studied for health benefits.

The Discovery

In the 1970s Bang and Dyerberg discovered that despite a diet high in fat*, Greenland Eskimos had an astonishingly low risk of cardiac death, heart attack, coronary heart disease and cancer when compared to the Danish population. This discovery imitated a significant amount of research about long chain Omega-3 fatty acids as indicated by the several thousand papers that have emerged.

  • Seal Oil: DHA, EPA and DPA
  • DHA
  • Docosahexaenoic acid (DHA, 22:6 n-3)
  • DHA is generally associated with neurological and ocular health benefits and benefits to the nervous system. Many experts recommend an increased intake of DHA for expectant and nursing mothers as well as infants because of their obvious benefits.
  • DHA is recognized as a physiologically essential nutrient in the brain and retina and is therefore needed for neuronal functioning and visual acuteness. Even Health Canada has recognized the benefits of DHA, which has led to the addition of regulated, restricted amounts of DHA in various foods such as eggs, milk, cheese, bread, etc.
  • EPA
  • Eicosapentaenoic acid (EPA, 20:5 n-3)
  • EPA has many health benefits for the heart and cardiovascular system. An increased intake of EPA is generally associated with a lower risk of primary and secondary heart attack rates, death from cardiovascular disease and all-cause mortality.
  • In one study, higher EPA levels in blood serum phospholipids resulted in a 70% lower risk of fatal ischemic heart disease. This means more EPA is beneficial in people with documented coronary heart diseases, especially those with risk factors for sudden cardiac death
  • DPA
  • Docosapentaenoic acid (DPA, 22:5 n-3)
  • Found only in marine sources of long-chain omega-3 fatty acids.
  • DPA is often overlooked as a significant component of long-chain Omega-3 fatty acids. This is primarily because most Omega-3 studies are conducted using fish or fish oil that contain only small amounts of DPA. Relatively few studies have been done using seal oil with its much higher content of DPA. DPA works with EPA and DHA to provide health benefits to the heart and to mothers and children.
  • Studies have shown that DPA has health benefits for the heart. Population studies show that higher levels of DPA result in lower rates of coronary heart disease risks. In addition, while EPA is known for its cardiovascular benefits, DPA is said to be ten times more effective than EPA in healing damaged blood vessels.

Seal Oil: Omega-3

Research shows that dietary supplementation of long-chain Omega-3 fatty acids can provide health benefits to every cell in the body and especially benefits the brain, eyes, nervous system and heart.

There are three significant long-chain Omega-3 fatty acids are:

  • Eicosapentaenoic acid (EPA, 20:5 n-3)
  • Docosahexaenoic acid (DHA, 22:6 n-3)
  • Docosapentaenoic acid (DPA, 22:5 n-3)

Seal oil in liquid and capsule form contains the highest levels of DPA and balanced levels of DHA and EPA. Seal oil Omega-3 fatty acids are chemically similar to that found naturally in the body from birth. However, long-chain Omega-3 fatty acids deplete daily as our bodies use them for numerous vital functions and should be supplemented accordingly.

The body does not produce the necessary long-chain Omega-3 fatty acids that are required in every cell for optimal health. Therefore, we need to get long-chain Omega-3 fatty acids from our diet.

Recommendations

 

The following governments and international organizations have recommended an increase in long-chain Omega-3 intake:

  • Health Canada
  • Governments of Australia and New Zealand (both governments recommend an increase in DPA intake, specifically)
  • American Heart Association
  • World Health Organization
  • European Society for Cardiology
  • United Kingdom Scientific Advisory Committee on Neutrino
