Excessive salt intake is linked to health issues like high blood pressure and heart disease. The American Heart Association recommends limiting sodium to 2,300 mg per day, ideally 1,500 mg for optimal health. High sodium levels can cause fluid retention, increasing cardiovascular strain. Studies show that reducing salt intake can lower blood pressure by 2-8 mm Hg, reducing the risk of heart disease and stroke. Moderation is key to maintaining health.
