Iceberg lettuce

卷心莴苣

Darker greens may have more nutrients, says Prevention magazine, but that doesn’t mean iceberg has none. If an iceberg wedge is your favorite salad, note that one cup of shredded leaves delivers about 20 percent of your daily needs for vitamin K, and 15 percent for vitamin A. Even if you use iceberg as a salad base for other healthy veggies, you've got a great vehicle for overall nutrition.

Prevention杂志说深绿色植物富含的营养成分也许更多， 但这也不意味着卷心莴苣就没有营养。如果卷心菜叶是你最喜欢的沙拉，那就记住一杯菜叶能给你提供每日所需20%的维他命K和15%的维他命A。即使菜叶只是用来作为其他健康蔬菜的色拉搭配，你也可以从中获得充分的营养。

Popcorn

爆米花

Real, popped-at-home corn is a terrifically healthy snack. It may even have more antioxidants than certain fruits and vegetables, researchers at the University of Scranton in Pennsylvania found last year. Air-popped and without butter, it’s low in fat and high in fiber, says nutrition expert Joy Bauer, RD—“five grams of fiber in a four-cup portion is pretty darn impressive for a snack food.”

在家做的爆米花真的是非常健康的小吃。宾夕法尼亚州斯克兰顿大学的研究者发现自制爆米花所富含的抗氧化剂也许比水果和蔬菜中含的还要多。营养专家Joy Bauer说，不加黄油的蒸汽爆米花含较低脂肪较高纤维。“4杯分量的爆米花就含有5克纤维，是绝好的零食。”
