Potatoes are among the foods richest in potassium, a mineral that fights high blood pressure.  One baked potato with skin contains 903 mg of potassium, nearly one-third of the recommended Daily Value.  And, in 2005 researchers from the Institute of Food Research (United Kingdom) found that the potato contains natural compounds known as kukoamines, that in an herbal remedy (Lycium chinense) are associated with blood-pressure reducing properties.
