Few chocolate squares a day can keep heart attack away

ISLAMABAD: A few squares of chocolate a day can almost halve the risk of heart attack death in some people, says a study. But scientists warn that eating more of it could be bad for health.
Researchers have known for nearly two decades that dark chocolate, rich in chemicals called flavonoids, lowers blood pressure and has other beneficial effects on blood flow.

The latest study on 139 people by Diane Becker, a professor at The Johns Hopkins University School of Medicine and Bloomberg School of Public Health and other researchers, identified the effect of normal, everyday doses of chocolate found in ordinary foods.

They found that just a few squares of chocolate a day can almost halve the risk of heart attack death in some men and women by decreasing the tendency of platelets to clot in narrow blood vessels, reported Newswise wire.

"Eating a little bit of chocolate or having a drink of hot cocoa as part of a regular diet is probably good for personal health, so long as people don't eat too much of it, and too much of the kind with lots of butter and sugar," said Becker.

The chemical in cocoa beans has a biochemical effect similar to aspirin in reducing platelet clumping, which can be fatal if a clot forms and blocks a blood vessel, causing a heart attack, the researcher said.

Becker cautioned that her work is not intended as a prescription to gobble up large amounts of chocolate candy, which often contains diet-busting amounts of sugar, butter and cream.

But as little as two tablespoons a day of dark chocolate - the purest form of the candy made from the dried extract of roasted cocoa beans - may be just what the doctor ordered.

"We have to be careful to emphasise that one single healthy dietary practice cannot be taken alone, but must be balanced with exercise and other healthy lifestyle practices that impact the heart," said study co-author Nauder Faraday, an associate professor at Hopkins. 本人认领这篇,如果48小时未交稿,其他战友自由认领 http://paktribune.com/news/index.shtml?160116

每天一点巧克力可以预防心脏病发作

伊斯兰堡:一项研究表明,每天吃一点巧克力可使心脏病死亡减少一半。但是科学家警告:过多食用巧克力对健康有害。

Researchers have known for nearly two decades that dark chocolate, rich in chemicals called flavonoids, lowers blood pressure and has other beneficial effects on blood flow.
近二十年来,研究人员发现富含类黄酮的黑巧克力有降低血压的作用,且对血液流动有好处。

The latest study on 139 people by Diane Becker, a professor at The Johns Hopkins University School of Medicine and Bloomberg School of Public Health and other researchers, identified the effect of normal, everyday doses of chocolate found in ordinary foods.
最近由约翰霍普斯金大学医学院和布鲁姆伯格公共卫生学院的Diane Becker教授及其他研究人员对139人进行了研究,结果证实日常饮食中每天摄入一定量巧克力对心脏病有益。

They found that just a few squares of chocolate a day can almost halve the risk of heart attack death in some men and women by decreasing the tendency of platelets to clot in narrow blood vessels, reported Newswise wire.
Newswise wire报道,他们发现每天一小块巧克力几乎可使心脏病死亡减少一半,这主要是由于减少了狭窄血管中血小板的聚集。

"Eating a little bit of chocolate or having a drink of hot cocoa as part of a regular diet is probably good for personal health, so long as people don't eat too much of it, and too much of the kind with lots of butter and sugar," said Becker.
“吃一小块巧克力或喝一杯热可可饮料做为普通膳食的一部分可能对健康有益,但不要吃太多,那些富含奶油和糖的巧克力也应避免食用。”Becker 说。

The chemical in cocoa beans has a biochemical effect similar to aspirin in reducing platelet clumping, which can be fatal if a clot forms and blocks a blood vessel, causing a heart attack, the researcher said.
研究人员说,可可豆中的化学物质具有和阿司匹林类似的生物化学效应,即减少血小板聚集。如果血小板聚集形成血凝块堵塞血管,就可引起心脏病发作,甚至死亡。

Becker cautioned that her work is not intended as a prescription to gobble up large amounts of chocolate candy, which often contains diet-busting amounts of sugar, butter and cream.
