Potassium plays a crucial role in maintaining various bodily functions, particularly in regulating fluid balance, muscle contractions, and nerve signaling. This essential mineral helps manage blood pressure levels by counteracting the effects of sodium. In muscles, potassium aids in contraction and helps prevent cramps during physical activity. Additionally, it supports cardiovascular health by maintaining proper heart function and rhythm. Foods rich in potassium, such as bananas, sweet potatoes, and spinach, are vital for achieving adequate intake, promoting overall health and wellness throughout the body.
