Drinking too much fruit juice linked to risk of early death
生機飲食是現在是很多人提倡的生活方式，但多喝果蔬汁，真的會讓你更健康嗎？
在上週五，美國發表的一項最新研究報告中稱，即便是100%的純果汁，它的含糖量也會對人類的身體健康狀況構成風險。
Many sugar-sweetened beverages have little to no nutritional value and lots of calories, and their harmful health effects have been well-documented. Now, a study links drinking too many sugary beverages -- and even 100% natural fruit juices -- to an increased risk of early death.
很多含糖飲料基本沒有營養價值且富含卡路里，已經有充足的證據來說明它們的健康危害。現在，有一項最新研究表明，喝太多含糖飲料會增加早逝風險，即使它是100%天然果汁。
well-documented ['wel'dɔkjumentid]：adj.證據充分的
Specifically, drinking an excessive amount of fruit juice could lead to an increased risk of premature death ranging from 9% to 42%, according to the study, published Friday in the journal JAMA Network Open.
上週五（5月17日）發表在《美國醫學會雜誌• 網絡開放》(JAMA Network Open)上的這項研究詳細指出，過量飲用果汁可能導致過早死亡的風險增加9%至42%不等。
Overall, the sugars found in orange juice, although naturally occurring, are pretty similar to the sugars added to soda and other sweetened beverages, the study suggests.
研究表明，雖然總體來看，橙汁中發現的糖雖然是天然存在的，但與汽水和其他加糖飲料中的糖非常相似。
"Sugary beverages, whether soft drinks or fruit juices, should be limited," Jean A. Welsh, a co-author of the study and an assistant professor in the Department of Pediatrics at Emory University in Atlanta, wrote in an email.
研究報告作者之一、美國亞特蘭大埃默裡大學兒科學助理教授吉恩•A•威爾士說：“含糖飲料，無論是軟飲料還是果汁，都應該加以限制。”
增加心血管疾病風險
Seven US cities, including New York and most recently Philadelphia, have levied taxes on sweetened drinks with added sugar in an effort to reduce consumption.
美國包括紐約在內的7個城市，已對添加糖的甜飲料徵稅，以減少人們的消費。最近，費城也採取了同樣的措施。
The new study defined "sugary beverages" as both sugar-sweetened thirst-quenchers, like soda and fruit-flavored infusions, and 100% natural fruit juices that have no added sugar. So how does fruit juice stack up against soda?
這份新研究定義了含糖飲料：汽水和水果味飲料等飲品、以及100%無添加糖的天然果汁。那麼果汁與和汽水相比較又如何呢?
"Previous research has shown that high consumption of sugars like those in soft drink and fruit juices is linked to several cardiovascular disease risk factors," Welsh explained.
威爾士解釋說：“此前的研究表明，從軟飲料和果汁中攝入太多糖分與數個心血管疾病風險因素相關。”
Obesity, diabetes and elevated triglycerides (a type of fat found in the blood) are among the risk factors linked to excessive sugar intake. "Few studies have been able to look at how this consumption might impact mortalityrisk," she said.
肥胖症、糖尿病和甘油三酯（血液中的一種脂肪）升高是與攝入過多糖分相關的風險因素。她說：“之前的研究基本沒有涉及這種糖分攝入會構成死亡風險。”
mortality [mɔː'tælɪtɪ]：n.死亡數，死亡率

Welsh and her coauthors analyzed data from 13,440 adults 45 and older, nearly 60% men and almost 71% of them overweight or obese.
威爾士與其同事分析了13440名45歲及以上成年人（近60%為男性，其中近71%為超重或肥胖）的相關數據。
People who consumed 10% or more of their daily calories as sugary beverages had a 44% greater risk of dying due to coronary heart disease and a 14% greater risk of an early death from any cause compared with people who consumed less than 5% of their daily calories as sugary beverages, the study showed.
研究顯示，與每日攝入的卡路里中不到5%來自於含糖飲料的人們相比，每日攝入的卡路里中的10%以上來自含糖飲料的人們死於冠心病的風險要高出44%，因任何原因早逝的風險也要高出14%。
Each additional 12-ounce serving of fruit juice per day was associated with a 24% higher risk of death from any cause, and each additional 12-ounce serving of sugary beverages per day was associated with an 11% higher risk.
每天每增加12盎司（約合355ml）的果汁攝入量，任何原因導致的死亡風險都將增加24%；每增加12盎司的含糖飲料，風險會增加11%。
建議的果汁攝入量是多少？
This is one of the first studies to examine the relationship between sugary drinks, including 100% fruit juices, and early death, wrote Marta Guasch-Ferré, a research scientist in the Department of Nutrition at Harvard T.H. Chan School of Public Health and Dr. Frank B. Hu, a professor of medicine at Harvard Medical School, in an editorial published alongside the new study.
哈佛大學陳曾熙公共衛生學院營養學研究科學家瑪爾塔•瓜施-費雷及哈佛醫學院教授弗蘭克•B•胡博士在與這項新研究一同發表的一篇文章中寫道，這是研究包含純天然果汁在內的含糖飲料與早逝之間關係的最早的研究之一。
"Although fruit juices may not be as deleteriousas sugar-sweetened beverages, their consumption should be moderated in children and adults, especially for individuals who wish to control their body weight," Guasch-Ferré and Hu wrote.
兩位教授還寫道：“儘管果汁可能不像加糖飲料有那麼多害處，但兒童和成年人還是應該節制果汁的攝入量，尤其是那些希望控制體重的人。”
deleterious [,delɪ'tɪərɪəs]：adj.有毒的，有害的
The recommendations for kids between 1 and 6 years old are to limit fruit juice consumption to 6 ounces per day, while children 7 years and older, teens and adults should limit fruit juice to 8 ounces per day, according to the American Academy of Pediatrics and the Dietary Guidelines for Americans.
美國兒科學會和美國飲食指南建議，1到6歲兒童對果汁的攝入量應控制在每天6盎司（約合177ml）之內，而7歲及以上兒童、青少年及成人每天攝入量應限制在8盎司（約合237 ml）之內。
"Further research is needed to examine the health risks and potential benefits of specific fruit juices," Guasch-Ferré and Hu said.
兩位教授寫道：“特定果汁對健康造成的風險及其潛在益處還需進一步研究。”
Welsh said we need to consider both fruit juices and sugar-sweetened beverages when we think about how much sugar we consume each day. Between the two, she tipped the scales in favor of fruit juice: "Given its vitamin and mineral content, fruit juice in small amounts may have a beneficial effect that isn't seen with sodas and other sugar-sweetened beverages."
威爾士說，在考慮我們每天攝入多少糖分時，我們需要考慮到果汁和含糖飲料。在這兩者之間，她更偏向於果汁，“果汁中富含維生素和礦物質，少量果汁對健康有益，而汽水和其他含糖飲料沒有這種益處。”
