A high-sodium diet can negatively impact health by increasing the risk of hypertension (high blood pressure), which can lead to cardiovascular disease and stroke. Excess sodium causes the body to retain water, raising blood volume and putting extra strain on blood vessels. Additionally, a diet high in sodium is often associated with processed foods that lack essential nutrients, leading to imbalances in overall dietary intake. Maintaining a balanced sodium level is crucial for promoting heart health, reducing the risk of chronic diseases, and supporting overall well-being.
