Green and black tea come from the same plant, but green tea is less processed. Because of this, it has a relatively high concentration of something called catechins（兒茶素）. Catechins are part of a bioactive compound known as a flavonoid（類黃素）, which is thought to reduce oxidative stress.翻譯：綠茶和紅茶來自同一種植物，但綠茶加工較少。正因如此，它兒茶素濃度含量小隊(duì)較高。兒茶素是一種被被稱為類黃酮的生物活性化合物的一部分，它被認(rèn)為可以減少氧化應(yīng)激。2. Green tea may help people lose weight but probably not enough so they can skip a workout or eat an extra piece of pie. One review looked at randomized control trials where people were given a preparation of green tea. There was a small amount of weight loss, particularly for Asians, but it was unclear whether it was the caffeine, green tea or ethnicity that was responsible.翻譯：綠茶可以幫助人們減肥，但覺得喝了綠茶就可以不鍛煉或者可以多吃一塊餡餅還遠(yuǎn)遠(yuǎn)不夠。一項(xiàng)研究審視了一些隨機(jī)對(duì)照試驗(yàn)，在這些試驗(yàn)中，人們被給予了綠茶制劑。（喝了這些職級(jí)的人）體重有輕微減輕，特別是亞洲人，但尚不清楚是咖啡因、綠茶還是種族特點(diǎn)引起的。3. Another study found that when people did lose weight through green tea, they were not drinking actual tea but preparations of concentrated green tea that are equivalent to 15 cups of normal green tea a day.翻譯：另一項(xiàng)研究發(fā)現(xiàn)，當(dāng)人們通過綠茶減肥時(shí)，他們不是喝真正的茶，而是喝濃縮綠茶的制劑，相當(dāng)于每天15杯普通綠茶。4. In 2009, experts conducted a broad review of research on green tea but found insufficient evidence that it prevents cancer. Observational studies seem to show it slows the growth of precancerous lesions（癌前病變）, but experts have been unable to establish whether or not it reduces the risk of cancer itself.翻譯：2009年，專家們對(duì)綠茶的研究進(jìn)行了廣泛的審視，但沒有足夠的證據(jù)證明綠茶可以預(yù)防癌癥。觀察性研究似乎顯示它能減緩癌前病變的生長，但專家們無法確定它是否能降低癌癥本身的風(fēng)險(xiǎn)。你的感悟：生活當(dāng)中，很多細(xì)小的決定會(huì)對(duì)整體健康產(chǎn)生很大的影響。例如：走樓梯兩分鐘、選擇吃燒烤而不是油炸食物，或者拒絕額外的一杯葡萄酒，都可以延長壽命?？紤]到這些問題的重要性，有些人想知道他們是否應(yīng)該放棄早晨的咖啡而選擇綠茶。關(guān)于綠茶益處的證據(jù)仍在研究之中，我們不知道它是否是更健康的選擇。但是，如果你想轉(zhuǎn)變一下生活方式，那么你可以考慮一下。本文節(jié)選自 CNN Hot beverages may cause cancer10喝綠茶真的對(duì)身體有好處嗎？課程導(dǎo)讀 Reading the tea leaves about whether drinking green tea is good for youGreen and black tea come from the same plant, but green tea is less processed. Because of this, it has a relatively high concentration of something called catechins（兒茶素）. Catechins are part of a bioactive compound known as a flavonoid（類黃素）, which is thought to reduce oxidative stress.Green tea may help people lose weight but probably not enough so they can skip a workout or eat an extra piece of pie. One review looked at randomized control trials where people were given a preparation of green tea. There was a small amount of weight loss, particularly for Asians, but it was unclear whether it was the caffeine, green tea or ethnicity that was responsible.Another study found that when people did lose weight through green tea, they were not drinking actual tea but preparations of concentrated green tea that are equivalent to 15 cups of normal green tea a day. Even with that high concentration, any weight loss was small and unlikely to reach the 5% to 10% of body weight needed to improve cardiovascular health.In 2009, experts conducted a broad review of research on green tea but found insufficient evidence that it prevents cancer. Observational studies seem to show it slows the growth of precancerous lesions（癌前病變）, but experts have been unable to establish whether or not it reduces the risk of cancer itself. Studies since the review, including a prostate and colorectal cancer（結(jié)直腸癌）randomized trial, have likewise not been able to establish a preventative effect.If all this leaves you still wondering if green tea is good for you, the larger studies do share one conclusion: it does not appear to be harmful. "If it's something you enjoy, then you should have it. A cup or two of green tea with a healthy diet of fruits and vegetables is great" said the researchers.7
