Excessive sodium intake in diets can have significant health implications, primarily leading to hypertension or high blood pressure. Elevated blood pressure increases the risk of cardiovascular diseases, including heart attacks and strokes. High sodium consumption can also cause fluid retention, leading to swelling and discomfort. Moreover, a diet high in sodium may negatively impact kidney function over time. For these reasons, it is recommended to limit sodium intake by choosing fresh foods, reading labels, and minimizing processed food consumption, thereby promoting better heart health.
