Sodium is a chemical element and an essential mineral that plays a key role in various bodily functions. It is commonly found in table salt and many processed foods. Sodium helps maintain the balance of fluids in the body, supports nerve function, and is vital for muscle contraction, including the heart muscle.
Understanding sodium is important for health because consuming too much can lead to high blood pressure and increase the risk of heart disease and stroke. Many people exceed the recommended daily intake of sodium, especially those who frequently eat fast food or processed snacks. Monitoring sodium intake can help manage overall health and reduce the risk of chronic conditions.
In the body, sodium works mainly to control fluid levels. It helps draw water into the bloodstream and ensures that cells maintain their shape and function properly. Sodium also assists in transmitting signals between nerves, which is essential for muscle movement and heart function.
It is important to balance sodium intake with potassium, another mineral that helps offset the effects of sodium on blood pressure. While sodium is necessary for health, too much can be harmful, so it is essential to be mindful of how much is consumed in the diet.
