Salt is an essential mineral that the body needs to function properly. It plays a crucial role in regulating fluid balance, nerve function, and muscle contractions. However, consuming too much salt can have negative effects on health. Excessive salt intake is linked to high blood pressure, which increases the risk of heart disease, stroke, and other cardiovascular problems. Therefore, while salt is necessary for bodily functions, it's important to consume it in moderation and be mindful of added salt in processed and packaged foods.
