Eating fish linked to longer life: US study 美國研究:吃魚與較長壽有關

People aged 65 and older who eat fish may live an average of two years longer than people who do not consume the omega-3 fatty acids found mainly in seafood, a US study suggests.

People with higher levels of omega-3 fatty acids in their blood also had an overall risk of dying that was 27 percent lower, and a risk of dying from heart disease that was 35 percent lower, than counterparts who had lower levels, said the study.

The research was led by scientists at the Harvard School of Public Health and was published in the Annals of Internal Medicine.

While other studies have demonstrated a link between omega-3 fatty acids and lower risk of heart disease, this research examined records of older people to determine any link between fish-eating and death risk.

Researchers scanned 16 years of data on about 2,700 US adults aged 65 or older. Those considered for the study were not taking fish oil supplements. Those with the highest blood levels of omega-3 fatty acids had the lowest risk of dying from any cause, and lived an average of 2.2 years longer than those with low levels.

美國研究顯示,主要來自海鮮的omega-3脂肪酸讓六十五歲以上的吃魚民眾,可能比不吃者平均多活兩年。

這份研究說,omega-3脂肪酸較高的人,死亡的整體風險低百分之二十七,因心臟病死亡的風險,比血中omega-3脂肪酸較低者低百分之三十五。

這份研究是由哈佛公共衛生學院科學家領導,刊登在《內科醫學年鑑》。

其他研究早已顯示,omega-3脂肪酸與心臟疾病風險較低之間有所關聯,但這份研究檢視較年長者的紀錄,來判定吃魚與死亡風險是否有關聯。

研究人員檢視美國約兩千七百名六十五歲與六十五歲以上成年人的十六年數據,那些研究對象都是不吃魚油補充品的人。血中omega-3脂肪酸最高的人,因任何原因死亡的風險最低,與血液中omega-3脂肪酸低的人相較,壽命平均長二點二年。
