A high-sodium diet can significantly negatively impact health. Excess sodium is associated with elevated blood pressure, known as hypertension, which increases the risk of heart disease and stroke. Furthermore, high sodium intake can lead to kidney damage and may promote fluid retention, resulting in swelling and discomfort. It can also disrupt calcium balance in the body, potentially leading to issues such as osteoporosis. Reducing sodium can improve overall heart health and mitigate these associated risks, highlighting the importance of a balanced diet.
