1982年丹麦生理学家Dyerberg通过调查,首次报导居住在格陵兰岛的爱斯基摩人与西欧人相比,其心肌梗塞、血栓性疾病等心脑血管疾病发病率很低,原因在于大量食用海产鱼类。我国的流行病学调查结果也表明,生活在海岛和沿海地区的人群由于经常性食用海产食物,患心脑血管疾病较低。为什么海产食品能起到这些作用呢?科学家们经研究发现这是由于海产食物中富含ω-3必需脂肪酸(10～20％)的缘故,其中EPA(二十碳五烯酸)、DHA(二十二碳六烯酸)对减少和防止心脑血管疾病尤为重要,因此有人亦把DHA暂名为心脑素(Double Heart/Heacl Agent)。目前已揭示和确认的DHA、EPA在
In 1982, Dyerberg, a Danish physiologist, first reported that Eskimos living in Greenland had a very low prevalence of cardiovascular and cerebrovascular diseases such as myocardial infarction and thrombotic disease compared with Western Europeans, due to the large consumption of marine fish. The results of epidemiological survey in China also show that people living on islands and coastal areas suffer from cardiovascular and cerebrovascular diseases due to frequent consumption of seafood. Why do marine foods play these roles? Researchers have found that this is due to the fact that seafood foods are rich in omega-3 essential fatty acids (10-20%), of which EPA (eicosapentaenoic acid), DHA Docosahexaenoic acid) is particularly important for the reduction and prevention of cardiovascular and cerebrovascular diseases. Therefore, some people also refer to DHA as Double Heart / Heacl Agent. DHA, EPA has now been revealed and confirmed
