Potatoes
土豆
Nearly all Americans fail to meet dietary recommendations for potassium (97 percent) or dietary fiber (95 percent). On an equal weight basis, the white potato provides as much fiber as and more potassium than other commonly consumed vegetables or fruit. A medium skin-on baked potato weighs in at just 163 calories, a whopping 941 milligrams of potassium and 3.6 grams of fiber. (A banana, also white in color, provides 422 milligrams of potassium and 3.1 grams of fiber.) Potatoes also provide vitamin C, vitamin B6 and magnesium, in addition to small amounts of high-quality protein.
几乎所有的美国人都做不到饮食建议里说的钾含量达到97%或膳食纤维达到95%。在等重的情况下，白色马铃薯可以提供与普通蔬菜和水果等量的纤维，并且更多的钾元素。一个中等大小带皮的烤土豆仅包含163卡路里，但其中的钾含量却高达942毫克，纤维达3.6克。相比之下，香蕉只包含422毫克钾和3.1克纤维。土豆还富含维生素C，维生素B6和镁，此外还含有少量的高蛋白。
