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于控制体重，但一项新研究表明，这取决于你选择了哪些水果和蔬菜来吃。 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. 研究人员记录了117918名在研究开始时年龄在三四十岁的男性和女性的饮食情况，并对他们进行了为期24年的随访，期间每四年回访一次。 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. 在四年期间，每日蔬菜总摄入量增加，可令体重少增加0.25磅（约合0.11千克）；每日水果总摄入量增加，可令体重少增加0.53磅（约合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. 浆果摄入量增加与体重少增加1.11磅（约合0.50千克）相关，柑橘类水果摄入量增加与体重少增加0.27磅（约合0.12千克）相关。豆腐或大豆的日摄入量增加与体重少增加2.47磅（约合1.12千克）相关，苹果或梨的日摄入量增加与体重少增加1.24磅（约合0.56千克）相关。胡萝卜和辣椒也与体重增量减少相关，但土豆、豌豆和玉米无此效果。 |
