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.
幾乎所有的美國人都做不到飲食建議里說的鉀含量達(dá)到97%或膳食纖維達(dá)到95%。在等重的情況下，白色馬鈴薯可以提供與普通蔬菜和水果等量的纖維，并且更多的鉀元素。一個(gè)中等大小帶皮的烤土豆僅包含163卡路里，但其中的鉀含量卻高達(dá)942毫克，纖維達(dá)3.6克。相比之下，香蕉只包含422毫克鉀和3.1克纖維。土豆還富含維生素C，維生素B6和鎂，此外還含有少量的高蛋白。
