Image Caption : Potassium is an electrolyte that plays roles in many physiological processes, including the electrical activity of the heart. Blood levels of potassium are tested in patients with virtually any type of serious illness, but it is also usually ordered (along with other electrolytes) during routine physical exams, especially in patients who are taking diuretics or medications for blood pressure or heart disease.
Potassium is a mineral that the body needs to work normally. It helps nerves and muscles communicate. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium's harmful effects on blood pressure.
Most people get all the potassium they need from what they eat and drink. Sources of potassium in the diet include
- Leafy greens, such as spinach and collards
- Fruit from vines, such as grapes and blackberries
- Root vegetables, such as carrots and potatoes
- Citrus fruits, such as oranges and grapefruit
