Which is more effective in hypertension?: Salt-free diet vs DASH diet

The salt-free diet was more efficient than for lowering SBP. However, the fact that sodium and soluble fiber intakes in the DASH diet group were higher than those in the salt-free diet group at the end of the first month, unlike at the beginning (P < .05), suggests that restricting the salt content of the DASH diet in hypertension could lead to more favorable outcomes on blood pressure, considering its suitability for a healthy diet.
