Tea 'healthier' drink than water
The researchers recommend people consume three to four cups a dayDrinking three or more cups of tea a day is as good for you as drinking plenty of water and may even have extra health benefits, say researchers.
研究者指出，人們若每天飲用三到四杯茶，對於健康的好處不下於喝下大量的水，而且喝茶對於健康還有額外的好處。
The work in the European Journal of Clinical Nutrition dispels the common belief that tea dehydrates.
歐洲臨床營養學期刊的研究駁斥了茶會使人脫水這樣的成見。
Tea not only rehydrates as well as water does, but it can also protect against heart disease and some cancers, UK nutritionists found.
英國的營養學家發現，茶不僅和水具有相同的補充水分的功效，而且還可以預防心臟疾病和某些種類的癌症。
Experts believe flavonoids are the key ingredient in tea that promote health.
專家相信黃酮體是茶促進健康的關鍵成分。
Healthy cuppa來杯健康
These polyphenol antioxidants are found in many foods and plants, including tea leaves, and have been shown to help prevent cell damage.
這些多酚類的抗氧化物質存在於許多食品與植物中，包括茶葉的葉片，並且已經被證實有助於預防細胞的損壞。
Public health nutritionist Dr Carrie Ruxton, and colleagues at Kings College London, looked at published studies on the health effects of tea consumption.
公共健康營養學者凱力洛克斯頓博士以及其倫敦國王學院的同僚們檢視了已發表的、針對飲用茶對於健康的影響的研究報告。
They found clear evidence that drinking three to four cups of tea a day can cut the chances of having a heart attack.
他們發現了明確的證據證明每天飲用三到四杯茶可以減少得到心臟病的機會。
Some studies suggested tea consumption protected against cancer, although this effect was less clear-cut.
有些研究則指出飲用茶可以預防癌症，雖然這項效果尚未有明確的研究數據足以支持。
Other health benefits seen included protection against tooth plaque and potentially tooth decay, plus bone strengthening.
其他的好處包括了預防蛀牙以及牙菌斑，並且還可以強化骨骼。
Dr Ruxton said: "Drinking tea is actually better for you than drinking water. Water is essentially replacing fluid. Tea replaces fluids and contains antioxidants so it's got two things going for it."
洛克斯頓博士說：『喝茶確實比喝水還有益健康。喝水基本上只有體內水分新陳代謝的功能，而喝茶除了代謝水份以外還帶來了抗氧化物，這豈不是一舉兩得嗎！』
Rehydrating補充水分
She said it was an urban myth that tea is dehydrating.
她說茶會使人脫水是一種都會迷思。
"Studies on caffeine have found very high doses dehydrate and everyone assumes that caffeine-containing beverages dehydrate. But even if you had a really, really strong cup of tea or coffee, which is quite hard to make, you would still have a net gain of fluid.
『對於咖啡因所做的研究顯示了只有在非常高劑量的咖啡因之下才會使人脫水，但是因為這樣的研究報告使人們以為只要含有咖啡因的飲料都會使人脫水。但事實上縱使你喝了一杯非常非常濃的茶或咖啡，實際上你也不太可能泡出這麼高咖啡因濃度的飲品，你的水分攝取仍舊可以維持在正攝入的程度。』
"Also, a cup of tea contains fluoride, which is good for the teeth," she added.
『此外，茶葉含有氟化物，對於牙齒也非常有益。』她補充了這一點。
There was no evidence that tea consumption was harmful to health. However, research suggests that tea can impair the body's ability to absorb iron from food, meaning people at risk of anaemia should avoid drinking tea around mealtimes.
目前並沒有發現任何喝茶會有害健康的證據。然而，研究指出茶葉會妨礙人體對於食物中鐵質的吸收，這也就是說有貧血風險的人應該避免在用餐前後喝茶。
Dr Ruxton's team found average tea consumption was just under three cups per day.
洛克斯頓博士的研究團隊發現一般人平均的茶葉攝取量一天不到三杯。
She said the increasing popularity of soft drinks meant many people were not drinking as much tea as before.
她說軟性飲料的大行其道意味著人們比以前飲用更少的茶。
"Tea drinking is most common in older people, the 40 plus age range. In older people, tea sometimes made up about 70% of fluid intake so it is a really important contributor," she said.
Claire Williamson of the British Nutrition Foundation said: "Studies in the laboratory have shown potential health benefits.
『茶葉的飲用比較常見於年長者，也就是四十歲以上的族群。有時候茶葉幾乎是年長者70%的水分攝取，因此有非常重要的貢獻。』英國營養基金會的克萊兒威廉生說：『實驗室中的研究證明了茶葉對於健康的潛在益處。』
"The evidence in humans is not as strong and more studies need to be done. But there are definite potential health benefits from the polyphenols in terms of reducing the risk of diseases such as heart disease and cancers.
『茶葉對於人體的益處雖然尚未被明確地證明，還需要更多進一步的研究，但是多酚類對於預防心臟疾病以及癌症的潛在益處是不容置疑的。』
"In terms of fluid intake, we recommend 1.5-2 litres per day and that can include tea. Tea is not dehydrating. It is a healthy drink."
『我們建議的水分攝取量是每日1.5到2公升，茶葉的飲用也可以算在裡面。茶葉並不會使人脫水，它是一種健康的飲料！』
The Tea Council provided funding for the work. Dr Ruxton stressed that the work was independent.
茶業委員會資助了這項研究，但是洛克斯頓博士強調這項研究的獨立性。
