Cod Liver Oil: A Valuable Source of Omega-3 The use of cod liver oil has been around for centuries, beginning in the fishing villages of Scotland, Iceland, Norway, and Greenland. Originally used to help relieve the pains of rheumatoid arthritis and stiff joints, its value was not fully established until researchers examined it closely in the middle of the 20th century.
Cod liver oil is a valuable source of the omega-3 essential fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). It is also an excellent source of vitamin D. Good for the Heart The American Heart Association has endorsed omega-3 fatty acids as good for the heart. Supportive but inconclusive research shows that the consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease.
Two clinical studies concluded that including omega-3 rich foods or supplements in the diet could help prevent sudden death from abnormal heart rhythms. However, more studies are needed before a conclusive health benefit can be established. Other Benefits of Omega-3 Studies have shown that omega-3 fatty acids like those found in cod liver oil have beneficial effects on several conditions. For example, patients taking fish oil supplements saw notable reductions in tender joints and morning stiffness as well as an increase in grip strength. Studies have shown that fish oil supplements reduced the need for pain medications in patients with rheumatoid arthritis. Again, further research and studies are necessary before specific health benefits can be established.
Early laboratory studies appear to show that omega-3 fatty acids might prolong life in those with autoimmune disorders like diabetes. It also appears to decrease abdominal cramping, diarrhea, and pain associated with Crohn’s disease.
