Dr. Jørn Dyerberg is a renowned expert on omega-3 fatty acids who led a landmark 1970 study of Greenland Eskimos. The study found that despite a high-fat diet, the Eskimos had low rates of heart disease and inflammation due to high consumption of essential fatty acids like DHA and EPA from fish. The document then discusses using calamari oil as a source of DHA, noting its environmental benefits over fish oil and ability to provide a balanced ratio of DHA to EPA without a fishy taste or smell.
