你以爲所有的蔬果都能減肥嗎大綱

Eating More fruits and vegetables can help control weight, but a new study suggests that it depends on which fruits and vegetables you eat.

多吃水果和蔬菜有助於控制體重，但一項新研究表明，這取決於你選擇了哪些水果和蔬菜來吃。

Researchers recorded diet information for 117,918 men and women in their 30s and 40s at the start of a study and followed them for 24 years, with interviews at four-year intervals.

研究人員記錄了117918名在研究開始時年齡在三四十歲的男性和女性的飲食情況，並對他們進行了爲期24年的隨訪，期間每四年回訪一次。

An overall increase in a daily serving of vegetable or fruit over a four-year period led to less weight gained — 0.25 pounds less for vegetables, and 0.53 pounds for fruit.

在四年期間，每日蔬菜總攝入量增加，可令體重少增加0.25磅（約合0.11千克）；每日水果總攝入量增加，可令體重少增加0.53磅（約合0.24千克）。

Increased intake of berries was linked to a 1.11-pound lower weight gain, and of citrus fruits a 0.27-pound lower gain. Adding a daily serving of tofu or soy was tied to 2.47 pounds less weight gained, and of apples or pears 1.24 pounds less. Carrots and peppers were also linked to smaller gains, but potatoes, peas and corn were not.

漿果攝入量增加與體重少增加1.11磅（約合0.50千克）相關，柑橘類水果攝入量增加與體重少增加0.27磅（約合0.12千克）相關。豆腐或大豆的日攝入量增加與體重少增加2.47磅（約合1.12千克）相關，蘋果或梨的日攝入量增加與體重少增加1.24磅（約合0.56千克）相關。胡蘿蔔和辣椒也與體重增量減少相關，但土豆、豌豆和玉米無此效果。

The study, in PLOS Medicine, controlled for many health and behavioral variables, including changes in dozens of food and nutrient intakes apart from fruits and vegetables.

研究對健康和行爲方面的衆多變量，包括除水果和蔬菜之外的數十種食物和營養物質的攝入量的變化都進行了校正。該研究發表於《公共科學圖書館：醫學》(PLoS Medicine)雜誌上。

The lead author, Monica L. Bertoia, a researcher at the Harvard T.H. Chan School of Public Health, said that Americans’ fruit and vegetable intake was mostly fruit juices and potatoes. But, she said, “There are many fruits and vegetables that may be better choices — apples, pears, berries and nonstarchy vegetables.

研究的主要作者，哈佛大學公共衛生學院(Harvard T.H. Chan School of Public Health)的研究員莫妮卡·L·貝爾託亞(Monica L. Bertoia)說，美國人攝入水果和蔬菜主要是以果汁和土豆的形式。不過，“有許多水果和蔬菜——蘋果、梨、漿果和非澱粉類蔬菜會是更好的選擇。
