Potassium

Potassium is necessary for muscle contractions in the body. It is especially important to the heart muscle. High or low levels of potassium can cause serious irregularities of heartbeat. Some diuretics cause the kidneys to excrete large amounts of potassium from the body. Others "spare" potassium by preventing release. If you are taking diuretics, your doctor will likely check your potassium level on a periodic basis. You can maintain a good potassium level by eating foods high in potassium content. Good dietary sources of potassium include milk, yogurt, winter squash, tomatoes, apricots and cantaloupe. Other good sources are bananas, grapefruit, oranges, prunes, carrots, potatoes, raisins, spinach and dates.

If you suffer from chronically low potassium levels, either due to medicine side effects or from malnutrition, your health care provider can prescribe a potassium supplement.
