Compared with non-coffee drinkers, those who drank about three cups of coffee a day appeared to reduce their risk of getting heart problems or dying from them.
與不喝咖啡的人相比，每天喝大約三杯咖啡的人患上心臟病或死于心臟病的風(fēng)險(xiǎn)會(huì)降低。

The strongest benefits of coffee consumption were seen in reduced risks of liver disease, including cancer.
喝咖啡最大的健康益處是患肝臟疾病（包括肝癌）的風(fēng)險(xiǎn)降低。

But Prof Paul Roderick, co-author of the study, said the review could not say if coffee intake had made the difference.
但研究報(bào)告的合著者保羅-羅德里克教授說，研究結(jié)論無法證實(shí)這種差異是否由咖啡導(dǎo)致。

"Factors such as age, whether people smoked or not and how much exercise they took could all have had an effect," he said.
他說：“年齡、是否吸煙、每天做多少運(yùn)動(dòng)等因素都有影響。”

The findings back up other recent reviews and studies of coffee drinking so, overall, his message on coffee was reassuring.
這一研究結(jié)果支持了最近的其他幾項(xiàng)有關(guān)喝咖啡作用的綜述和研究，因此從總體上看，研究結(jié)果是可靠的。

"There is a balance of risks in life, and the benefits of moderate consumption of coffee seem to outweigh the risks," he said.
他說：“生活中各種風(fēng)險(xiǎn)之間存在平衡，適量飲用咖啡的益處看來比風(fēng)險(xiǎn)更大。”

The NHS recommends pregnant women have no more than 200mg of caffeine a day - two mugs of instant coffee - because too much can increase the risk of miscarriage.
英國(guó)國(guó)民健康保險(xiǎn)體系建議孕婦每天攝入的咖啡因不超過200毫克，也就是兩杯速溶咖啡的量，因?yàn)閿z入咖啡因太多會(huì)增大流產(chǎn)風(fēng)險(xiǎn)。

This review suggests women at risk of fractures should also cut back on coffee.
研究建議有骨折風(fēng)險(xiǎn)的女性也要少喝咖啡。

For other adults, moderate caffeine intake equates to 400mg or less per day - or three to four cups.
對(duì)其他成年人來說，每天攝入的咖啡因最好少于400毫克，大約相當(dāng)于三到四杯咖啡。

The researchers say coffee drinkers should stick to "healthy coffees" - which avoid extra sugar, milk or cream, or a fatty snack on the side.
研究人員表示，喝咖啡的人要堅(jiān)持喝“健康咖啡”，不要另外加糖、牛奶、奶油，或者高脂肪零食。

And they are calling for rigorous clinical trials on coffee intake to find out more about the potential benefits to health.
研究人員提議對(duì)咖啡攝入量進(jìn)行嚴(yán)格的臨床試驗(yàn)，以對(duì)咖啡潛在的健康益處有更多了解。

At present, the researchers said pinning down exactly how coffee might have a positive impact on health was "difficult".
目前，研究人員表示精確指出咖啡如何有益健康“有些困難”。
