When people think of inexpensive sources of potassium, bananas usually come to mind. However, researchers at the University of Washington found that potatoes are the greatest and cheapest source of potassium when compared to any other fruit or vegetable.
The scientists announced their findings at the recent American Dietetic Association’s Food and Nutrition Conference and Expo. They said that one medium-sized potato with the skin on contains about 110 calories, 620 milligrams of potassium and 45 percent of one’s daily recommended value of vitamin C.
“Potatoes deserve credit for contributing to higher diet quality and increasing vegetable consumption,” said lead researcher Adam Drewnowski, Ph.D. “Potatoes also play an important role in providing affordable nutrition to Americans.”
Previous research has shown that the potato’s bad reputation for being a fattening food may stem from the fact that many people eat their spuds fried or with sour cream or butter. The recent finding suggests that baked, steamed, boiled or roasted potatoes may be a healthy, affordable addition to a balanced dinner.
