Potassium plays a crucial role in maintaining health by regulating fluid balance, supporting muscle contraction, and facilitating nerve function. This essential mineral helps control blood pressure by counteracting the effects of sodium, thereby reducing the risk of cardiovascular diseases. Adequate potassium intake is also linked to improved bone health and reduced risk of kidney stones. Foods rich in potassium, such as bananas, potatoes, and spinach, should be included in a balanced diet to ensure that levels remain optimal. Monitoring potassium intake is particularly important for individuals with specific health conditions or those on certain medications.
