Women who regularly eat citrus fruits such as oranges and grapefruit may have a lower risk of blood-clot related stroke, according to a US study published on Thursday.
根據週四發表的一項美國研究指出，女性規律食用柳橙或葡萄柚等柑橘類水果，因血管阻塞相關因素中風的風險可能較低。
Researchers looked at 14 years of data from a US survey that included 69,622 women who reported what they ate, including details on fruit and vegetable consumption, every four years.
研究人員觀察一項美國調查所得到的14年資料，數據中6萬9622名女性每4年一次通報她們吃什麼，包括蔬果攝取的詳細資料。
The aim was to study the effects of flavonoids -- a class of compounds present in fruits, vegetables, dark chocolate and red wine -- on health. While total flavonoid consumption across all six main types found in the typical US diet did not show a benefit in preventing stroke, those who ate lots of oranges and grapefruit and their derived juices showed a 19 percent lower stroke risk than their counterparts in the study.
研究目的是觀察類黃酮對健康的影響。類黃酮是蔬果、黑巧克力與紅酒所含的一種複合物。雖然美國典型飲食主要6大類中的類黃酮攝取，並未發現有助預防中風，但食用大量柳橙與葡萄柚以及這種果汁的人，中風風險比研究中的同儕低19%。
"Studies have shown higher fruit, vegetable and specifically vitamin C intake is associated with reduced stroke risk," said Aedin Cassidy, lead author of the study in the Stroke︰Journal of the American Heart Association.
「研究顯示，較多蔬果、特別是維他命C的攝取，與中風風險低相關」，研究主要作者卡西迪在「中風：美國心臟協會期刊」中寫道。
The researchers called for more studies to better understand the apparent link, and urged women to consume oranges and grapefruit rather than their juices to avoid high sugar content from drink additives.（AFP）
研究人員呼籲進行更多研究，以更了解這種明顯的關連，他們並敦促女性攝取柳橙與葡萄柚，而非柳橙汁與葡萄柚汁，以避免飲料添加物的高糖分。
