Fish Oils are good for the heart. Heart death is virtually unheard of among the Greenland Inuits (Eskimos). Decades of research and hundreds of studies have confirmed that it was the omega 3 fish oils in their diet that protected them from heart disease.
In an article published in the British Medical Journal earlier this year, researchers from the Edinburgh University reviewed the worldwide evidence and found that fish oils look after the heart in several ways:
1) Helps reduce platelet aggregation (the clumping together of red corpuscles that can form a potentially fatal blood clot in a coronary artery.)
2) Atherosclerosis is a condition where fatty deposits narrow the artery and
hinder the blood flow. Fish oil supplementation has produced some
modest improvements in the condition
but, more importantly seems to make fatty deposits less likely to rupture
and trigger a heart attack.
3) Help regulate heartbeat. A sudden change in the heart’s normal rhythm (arrhythmia) can cause a heart attack or sudden death. (when death occurs without earlier signs or symptoms.
4) Inflammation of the arteries is thought to be an important indicator of future heart attacks and strokes. Men with high blood levels of C reactive protein have an increased risk of coronary heart disease and stroke. Omega 3 fatty acids have a recognized anti– inflammatory action.
5) Abnormalities in the lining of artery walls are linked to heart disease.
Omega 3 fatty acids maintain arterial health and widen arteries to
improve blood flow.
Back in Greenland, the Inuits are adopting the eating habits of their American neighbours except in the smaller villages that still maintain hunting and fishing traditions. As a result heart disease and arthritis are making an unwelcome appearance where once they were virtually unknown.
