《中英對照讀新聞》Chocolate improves blood vessel function巧克力有助於提升血管功能

◎ 魏國金

Chocoholics were given further reason to rejoice when a small clinical study showed that dark chocolate improves the function of blood vessels.

一項小型臨床研究顯示，黑巧克力有提升血管功能之效，讓酷愛巧克力的人更有理由歡欣雀躍。

During the six-week trial, 45 people were given 227 grams of cocoa without sugar, cocoa with sugar or a placebo each day.

在這項為期6週的試驗期間，45名受試者每天分別獲得227克 的無糖可可、含糖可可或安慰劑。

An upper arm artery’s ability to relax and expand to accommodate increased blood flow -- known as flow mediated dilation （FMD） -- was measured using high-frequency ultrasound before and after daily cocoa or placebo consumption.

在每日攝食可可或安慰劑前後，（研究人員）利用高頻超音波，對肱動脈因應增加之血流的舒張能力；亦即流量介導擴張（FMD）進行測量。

Of the 39 subjects who completed the trial, FMD improved significantly in both cocoa groups -- by 2.4 percent among those who had it without sugar and 1.5 percent among those who had it with sugar. It dropped 0.8 percent in the placebo group.

在39名完成試驗的受試者中，兩個可可群組的FMD明顯提升—攝取無糖可可者提升2.4%，含糖者為1.5%。安慰劑組則下降0.8%。

"While the findings from this study do not suggest that people should start eating more chocolate as part of their daily routine, it does suggest that we pay more attention to how dark chocolate and other flavonoid-rich foods might offer cardiovascular benefits,"said Dr. Valentine Yanchou Njike, a co-investigator of the study. .

該研究的共同研究員恩 吉克 博士說︰「這項研究的發現並不意謂著人們應多吃巧克力，每天都吃，而是表示我們應對黑巧克力與其他富含類黃酮素食品對心血管可能有的好處，多加注意。」
