Importance of Balance
Just as too little potassium can have serious consequences, excessive blood levels of potassium also can lead to complications. If the kidneys and circulatory system are functioning properly, it is virtually impossible to produce a dangerously high level of potassium in the blood through diet alone. High potassium levels may occur, however, in patients taking prescribed potassium supplements. But if potassium levels are too high, they must be treated to avoid a possible progression to more serious problems. Therefore, it is imperative that the patient follow the physician's dosage recommendations.
Sources of Potassium
The Recommended Daily Allowance (RDA) of potassium for adults is in the range of two to six grams per day, depending on body weight. The average American adult consumes 4.5 grams of potassium per day, which is well within these suggested guidelines. The best dietary sources of potassium are bananas, orange juice, raisins and other dried fruits, meats, peanut butter, bran, dried peas and beans and potatoes. Cocoa, coffee and tea also contain significant amounts of potassium.
Treatment of Potassium Depletion
An estimated two million Americans regularly take potassium supplements. Most are patients with high blood pressure, where potassium levels are lowered by their anti-hypertensive medications. In many instances, increased consumption of potassium-rich foods is all that is required. For others, however, additional potassium in the form of prescription supplements are needed. This is a determination that must be made by a physician.
Summing Up
Potassium is an essential mineral that is found in a variety of foods. The average healthy person consumes adequate potassium. However, it should be noted that a number of diseases and other circumstances, including the use of certain drugs, may upset the body's natural balance of fluids and chemicals and can lead to a potassium imbalance. Unless corrected, this imbalance can have serious consequences.
