Americans eat an average of 55 pounds (25kg) of these tubers every year. One medium size Russet contains plenty of vitamin C and more potassium than a banana. You’ll also find fiber and protein in potatoes, something your body needs to maintain a healthy weight and curb hunger. As part of a balanced diet, they are the perfect compliment to fish, chicken, beef or pork. You can even make a hearty, delicious soup out of potatoes, ham, and vegetables. Of course, you should also include other vegetables and plenty of fruits in your diet.
