五種應(yīng)該多吃的白色蔬菜

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.
