A high-sodium diet can have several adverse effects on health, primarily contributing to hypertension or high blood pressure. Elevated blood pressure increases the risk of heart disease, stroke, and kidney issues. Excessive sodium can also lead to fluid retention, creating discomfort and bloating. Over time, it may negatively impact vascular health and the body's ability to regulate water balance. Adopting a diet low in sodium—rich in fresh fruits, vegetables, and whole foods—can mitigate these risks and promote overall cardiovascular health.
