Our body cells need minerals in the form of crucial food to meet a medley of functions, from forging materials for our bones, muscles, heart, and brain to making enzymes and hormones and to other biologically active tasks such as maintaining the body's acid-base equilibrium, the body pH to neutral, nerve impulse transmission, and muscle contraction.
The seven vital minerals, or macro-minerals, include calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. Other minerals, known as trace minerals (required in smaller quantities), also serve as backups, including iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
Among the seven vital macro-minerals, most people naturally meet their adequate daily potassium requirement through a variety of foods. Potassium is an electrolyte that helps regulate blood and fluid levels. It further supports the proper functioning of the kidneys, heart, muscles, and nervous system.
Potassium and sodium are like two sides of the same coin since they work hand in hand. Potassium plays a significant role in the body by helping to maintain normal fluid levels both within and outside cells. Furthermore, potassium helps muscles contract and regulates blood pressure to normal levels.
The potassium level in your body can drop too low due to a low-potassium diet, immoderate alcohol drinking, and excessive use of laxatives, constipation, dehydration, excessive sweating, fatigue, persistent vomiting, diarrhea, adrenal gland disorders, medication like diuretics or water pills, and certain prescription medicines, including antibiotics. If the potassium level in the blood is low, the condition is called hypokalemia.
The most common cause of hypokalemia is attributed to substantial potassium loss through urine owing to the use of prescription medication (generally for those who have high blood pressure or heart disease), such as diuretics or water pills, which induce an increase in urination.
If the level of potassium in the blood drops too low, it can lead to several serious complications. These include cramps, numbness or tingling, diabetic ketoacidosis, chronic kidney disease, abnormal heart rhythms or arrhythmia, and in severe cases, muscle spasms, even paralysis, and possibly respiratory failure. These potential health risks underscore the importance of maintaining a balanced potassium level in your body. For instance, muscle cramps, especially in the legs, are a common symptom of hypokalemia. Numbness or tingling in the hands, feet, or other parts of the body can also indicate a potassium deficiency.
In cases of mild hypokalemia, people typically barely show symptoms. There is nothing to be alarmed about, though. The average blood potassium level should range from 3.6 to 5.2 millimoles per liter (mmol/L). A level below 3.6 mmol/L is considered low and may indicate hypokalemia. A simple blood test, recommended by your healthcare provider, can help determine your body's potassium level. Your doctor may also ask you to take a urine test to determine if you're losing potassium through your pee.
Hypokalemia, or dangerously low potassium levels, can affect your kidneys if left untreated. You may frequently have to visit the bathroom and more often feel thirsty. However, there are loads of potassium-rich foods that can work wonders in mild cases of hypokalemia. By incorporating these foods into your diet, you can take proactive steps to boost your potassium level and maintain your health.
A recommended daily potassium intake for a healthy adult male is 3,400 mg, and 2,600 mg for females. This daily intake, when met consistently, can significantly contribute to maintaining a healthy potassium level in your body. By understanding and meeting this requirement, you can feel confident in your ability to manage your potassium intake and maintain your health.
If you’re committed to maintaining a balanced diet rich in potassium, the following foods can be your allies in this journey. The good news is that your body absorbs approximately 85 percent–90 percent of the potassium from your diet, allowing you to take control of your potassium intake and remedy any deficiency.
The recommended potassium-rich foods:
- Fruits like dried apricots, raisins, prunes, oranges, bananas, avocados, and apples
- Vegetables, such as squash, potatoes, spinach, tomatoes, kale, silver beet, acorn, broccoli, zucchini, eggplant, carrots, sweet potatoes, and pumpkin
- Lentils include kidney beans, soybeans, walnuts, peanuts, and almonds
- Dairy products like milk, yogurt, and cream
- Meat—chicken and fish
The following juices are high in potassium: passion fruit juice, carrot juice, pomegranate juice, orange juice, prune juice, tomato juice, and vegetable juice. Even tea and coffee contain potassium.
Potassium, a macromineral, is essential for maintaining good health. It plays a crucial role in safeguarding kidney health, cardiovascular health, bone and muscle health, normal cell functioning, proper muscle and nerve mobility, protein synthesis, and carbohydrate metabolism. For instance, it helps regulate blood pressure, supports muscle function, and aids in the transmission of nerve impulses. Maintaining a healthy potassium level is therefore vital for overall health and well-being.
Before you consider taking any potassium supplements, it's crucial to consult your doctor. Excessive potassium intake can lead to hyperkalemia, a condition where there's too much potassium in your body. Remember, 'Let food be thy medicine and medicine be thy food.' This oft-quoted phrase, spoken by the father of modern medicine, Hippocrates, the ancient Greek physician, around 400 BC, has never been more relevant. It serves as a reminder to be cautious and responsible when it comes to your health.
