Frequently Asked Questions
q: What exactly is potassium?
Technically, potassium falls into two categories: it is both a mineral consumed through foods and an electrolyte produced within the body. Electrolytes are positively charged ions that help regulate several bodily functions including blood pressure, digestion, heart rate and normal heart functioning, muscle contractions, and features of the nervous system. Other conventional electrolytes include sodium, chloride, magnesium, bicarbonate, and calcium. For athletes, electrolytes play a critical role in supplying oxygen to the blood, and thus to the muscles (which ultimately provides energy for the body to run, jump, lift weights, etc. off of).
q: What is an electrolyte imbalance?
An electrolyte imbalance is when one of the types of electrolytes present in the body’s blood cells are either too high or too low. When this happens, the individual may experience several symptoms, including an irregular heartbeat, muscle weakness or general fatigue, notable changes in blood pressure, and problems within the nervous system
q: What are some of the benefits of consuming potassium?
Potassium offers many health benefits. Some of these stimulate cognitive and neural activity and increasing overall brain functioning and awareness, stabilizing blood sugar (which is especially essential for those with diabetes) reducing muscle disorders and helping muscle contractions and reactions to quicken and become more efficient, enhancing bone health by helping the body’s absorption of calcium, aiding in protein synthesis which may ultimately build muscle and boost the metabolism, regulate water and fluid levels, and regulating hormones which eventually may lead to decreased stress and anxiety.
q: What are the runner-ups? What other foods might be good sources of potassium?
Following a similar trend that already exists within our list, dark and leafy greens tend to be rich sources of potassium, so some other options not listed here are Swiss chard and Bok choy. Legumes are also excellent sources of potassium: Lima beans, soybeans, and pinto beans to name a few. Regular potatoes are also known to be good sources of potassium.
q: Can you have too MUCH potassium in your blood?
Yes. Having too much potassium in your blood is a condition known as hyperkalemia. It typically occurs when the kidneys, the main organ for regulating potassium levels, are not correctly removing excess potassium out of the body. It is mostly caused by medications that have this effect on the kidneys, and include drugs like diuretics, some blood pressure medications, and antibiotics (in particular, penicillin). When potassium remains in the kidneys, the symptoms can be serious. The symptom of highest concern is a dangerous change in heart rhythm. If you experience symptoms of possible hyperkalemia due to complications with your medicine, stop the use of the drug immediately, and talk to your doctor.
q: How can I help my family get used to eating healthier foods?
The best way to help yourself as well as your family get more accustomed to eating healthier foods is to start small and build slowly. Don’t change the entire diet right away- that is asking for rebellions and ultimate failure. Instead, change out one bad food for one good food and then slowly add new foods to replace old ones. Also, remember versatility is key. No one wants a bowl of beets every night with dinner so find other ways to work these and any other healthy foods that are also good sources of potassium into your normal menu plans.
