Habitual tea drinking `linked to longer life´
Drinking tea at least three times a week could be linked with a longer and healthier life, scientists say.
によれば new 研究 “habitual” 消費 of the hot drink is associated with lower 危険s of cardiovascular 病気 and all-原因（となる） death.
But whether the tea 存在 消費するd is green or 黒人／ボイコット may make a difference.
The 分析 含むd 100,902 関係者s of the 中国-PAR project2 with no history of heart attack, 一打／打撃, or 癌.
関係者s were categorised into two groups ? habitual tea drinkers, those drinking three or more times a week, and never or 非，不，無-habitual tea drinkers? ? those drinking いっそう少なく than three times a week.
They were followed-up for a median of 7.3 years, in the 熟考する／考慮する published in the European 定期刊行物 of Preventative Cardiology.

The 研究 示唆するs a 50-year-old habitual tea drinker would develop coronary heart 病気 and 一打／打撃 1.41 years later, and live 1.26 years, longer than someone who never or seldom drank tea.
Compared with never or 非，不，無-habitual tea drinkers, habitual tea 消費者s had a 20% lower 危険 of 出来事/事件 heart 病気 and 一打／打撃, and a 22% lower 危険 of 致命的な heart 病気 and 一打／打撃.
They also had a 15% 減少（する）d 危険 of all-原因（となる） death, the 熟考する／考慮する 示唆するs.
First author Dr Xinyan Wang, of the Chinese 学院 of 医療の Science in Beijing, said: “Habitual tea 消費 is associated with lower 危険s of cardiovascular 病気 and all-原因（となる） death.
“The favourable he alth 影響s are the most 強健な for green tea and for long-称する，呼ぶ／期間／用語 habitual tea drinkers.”
研究員s analysed the 可能性のある 影響（力） of changes in tea drinking behaviour in a subset of 14,081 関係者s with 査定／評価s at two time points.
The 普通の／平均（する） duration between the two 調査するs was 8.2 years, and the median follow-up after the second 調査する was 5.3 years.
Habitual drinkers who 持続するd their habit in both 調査するs had a 39% lower 危険 of 出来事/事件 heart 病気 and 一打／打撃, 56% lower 危険 of 致命的な heart 病気 and 一打／打撃, and 29% 減少（する）d 危険 of all-原因（となる） death compared to 一貫した never or 非，不，無-habitual tea drinkers, the 熟考する／考慮する 示唆するs.
In a sub-分析 by tea type, drinking green tea was linked with around 25% lower 危険s for 出来事/事件 heart 病気 and 一打／打撃, 致命的な heart 病気 and 一打／打撃, and all-原因（となる） death.
However, no 重要な 協会s were 観察するd for 黒人／ボイコット tea.
Scientists 設立する 49% of habitual tea drinkers in the 熟考する／考慮する 消費するd green tea most frequently, while only 8% preferred 黒人／ボイコット tea.
They 公式文書，認めるd a preference for green tea in East Asia, and said the small 割合 of habitual 黒人／ボイコット tea drinkers might make it more difficult to 観察する 強健な 協会s, but that the findings hint at a differential 影響 between tea types.
The 研究員s 示唆する a number of 推論する／理由s for this.
They 示す that green tea is a rich source of polyphenols which 保護する against cardiovascular 病気.
While 黒人／ボイコット tea is fully fermented and during this 過程 may lose antioxidant 影響s.
Gunter Kuhnle, professor of 栄養 and food science at the University of Reading, said: “This 熟考する／考慮する is an observational 熟考する／考慮する and can therefore only 設立する an 協会 ? not a causal 関係.”
He 追加するd that the two cups per week as 削減（する）-off point was very little when compared to the 普通の／平均（する） 消費 of three to four cups per day in the UK.
Prof Kuhnle said: “It is not （疑いを）晴らす from the 熟考する／考慮する whether there is any 利益 from higher tea intake ? and therefore there is no likely 利益 from 増加するing tea intake by the 大多数 of the British public.”
