Researchers have found white potatoes to be the largest and most affordable source of potassium of all fruits and vegetables; the cost of of potassium-rich white potatoes was half that of most other vegetables.
Potassium is a key electrolyte that maintains the body's fluid levels. The balance between sodium and potassium helps regulate blood pressure and heartbeat. Too much sodium and not enough potassium results in high blood pressure.
The study, presented at the American Dietetic Association's Food & Nutrition Conference, also found that people who consumed baked, boiled and roasted potatoes had higher intakes of potassium and vitamin C and consumed more total vegetables compared to those who did not consume potatoes.
Potassium-rich fruits include cantaloupe, bananas, oranges, strawberries, apricots, avocado, tomatoes, and papayas; vegetables, in addition to potatoes, are cabbage, brussels sprouts, bell peppers, okra, cucumber, eggplant, squash, and spinach. Other plant-based sources include lima beans, parsley, turmeric, nuts and seeds.
