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 li<x>nked 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 li<x>nked 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。
