Nutrition Tip:
Although a potato is a common staple food in many of our diets that often gets a bad rap, don't overlook the nutritional benefits and versatility of this starchy root vegetable. Whether you prepare them baked or broiled, in soups or salads, potatoes are a great source of protein, fiber, and vitamins and minerals, providing several health benefits.
As a tuberous root vegetable, potatoes are also a rich source of B-complex vitamins, including pyrixidine (B6), thiamin, niacin, pantothenic acid, and folate. Potatoes are also a great source of minerals, including iron, manganese, magnesium, copper, and potassium. A medium potato also provides about 37% of the daily value for vitamin C, an important immune-supporting antioxidant.
We suggest choosing local produce whenever possible and organic for items on the Dirty Dozen List, which includes potatoes and celery.
