進入《中英對照讀新聞》Vitamin D Boosts Lung Health 維他命D增進肺臟健康
◎ 陳成良
Higher amounts of vitamin D could help make it easier to breathe, according to new findings released recently, offering possible good news for smokers, asthmatics and other people with respiratory problems.
據最近公布的一項新發現指出，大量的維他命Ｄ可以讓呼吸更順暢。這項研究結果可望為吸菸者、氣喘患者，和其他呼吸系統有問題的人帶來好消息。
Researchers at the University of Auckland in New Zealand found people with higher levels of the vitamin D in their systems showed better lung function than those with lower amounts. While the vitamin, which people get mostly from sunlight, is linked to lung health, the exact relationship is unclear, they said. Their findings appear in the December issue of the American College of Chest Physicians’ journal, Chest.
紐西蘭奧克蘭大學的研究人員發現，身體系統中維他命Ｄ含量較高的人，比那些維他命Ｄ含量較少的人，肺臟功能更好。然而他們表示，儘管人們主要從陽光中吸收製造的這種維他命與肺臟的健康有關，但兩者之間確切的關聯仍不清楚。這項研究發現發表於12月的美國胸腔學院期刊。
Vitamin D can also be found in certain foods like fortified beverages and fatty fish like salmon and mackerel as well as dietary supplements.
維他命Ｄ也可在特定食物中找到，如強化飲料、高油脂魚類如鮭魚和青花魚，以及膳食補充品。
"Although there is a definite relationship between lung function and vitamin D, it is unclear if increases in vitamin D through supplements or dietary intake will actually improve lung function in patients with chronic respiratory diseases," said Dr. Peter Black, who led the study.
「雖然肺臟功能與維他命Ｄ之間的關係非常明確，但經由營養補給品，或是經由膳食攝取來增加維他命Ｄ，是否真能改善慢性呼吸系統病患的肺功能，目前還不清楚，」主持這項研究的彼得．布萊克博士說。
