Potassium is a mineral crucial in maintaining overall health and well-being. It is an electrolyte that carries an electrical charge when dissolved in fluids like blood. This property enables potassium to participate in various bodily functions, including nerve transmission, muscle contraction, and fluid balance.
One of potassium's primary functions is to regulate blood pressure. It does this by counteracting the effects of sodium, another electrolyte that can raise blood pressure when consumed in excess. Potassium helps to relax blood vessels, allowing blood to flow more easily and reducing the strain on the heart. Additionally, potassium maintains the body's pH balance, which is essential for proper cellular function.
Adequate potassium intake is essential for overall health, but it is especially important for individuals with high blood pressure or those at risk of developing it. Potassium-rich foods include fruits like bananas, oranges, and apricots, as well as vegetables like spinach, sweet potatoes, and broccoli. Dairy products, beans, lentils, and fish are also good sources of potassium. For individuals who struggle to meet their potassium needs through diet alone, a healthcare professional may recommend supplements.
