Rethinking Potassium Published: June 2005 When thinking of minerals that are important for our bodies, we may not often think of potassium. But Potassium deficiency affects a variety of individuals, especially mature adults, athletes, and people who consume too much sodium. High blood pressure can be an indicator of low potassium in the body. Low levels of potassium in anyone’s body could be dangerous—sometimes deadly. According to Dr. Michael Murray, author of the Encyclopedia of Nutritional Supplements, complications resulting from a potassium deficiency include cardiovascular disease, cancer, and possible death. Most doctors agree that the key to treating potassium imbalance is to identify who is at risk and encourage them to take preventative measures. Maintaining a diet rich in potassium is the best way to avoid a potential deficiency. The best sources of potassium are apples, bananas, carrots, potatoes, tomatoes, spinach, apricots, salmon, flounder, avocado, limas, and chicken. Why is it important to get enough potassium? Potassium is vital for proper muscle development and contraction, proper nerve function, and balancing the body’s fluid level. Your body also needs potassium to release energy from protein, fat, and carbohydrates during the metabolic process. Should I take a supplement? A potassium supplement is not necessary for those who maintain a balanced diet. A daily multi-vitamin will help meet your potassium needs. Concentrated supplements are available, so ask your doctor if you think you may be at risk for deficiency. How much is too much? Although there is no set reccomended intake for potassium, most Americans consume between two and six grams per day. Most healthy adults are not affected by potassium excess, but if you suffer from kidney dysfunction, you are urged to limit potassium intake—it could be toxic in your bloodstream. Like most minerals, too much potassium could inhibit the absorption of other key vitamins and nutrients.
