Before we start piling on the condiments, from butter and sour cream to chives and salt, potatoes are actually healthy foods. One plain baked potato contains almost the same amount of potassium as a banana and offers 45 percent of your recommended daily vitamin C.
A plain baked potato also has only about 7 mg of sodium (depending on its size), and if you skip the options at the potato bar, it's also a fat-free food. Be sure you don't discard the skin, though. Eating the whole potato, skin and all, adds 2 grams of fiber to your daily fiber intake, a recommended 30 to 38 grams per day for men and 21 to 28 grams per day for women.
