Does the combination of reduced dietary sodium and the DASH diet lower blood pressure more than either intervention alone?
Combining reduced sodium intake with the DASH diet provides greater blood pressure reduction than either intervention alone.
The reduction of sodium intake to levels below the current recommendation of 100 mmol per day and the DASH diet both lower blood pressure substantially, with greater effects in combination than singly. Long-term health benefits will depend on the ability of people to make long-lasting dietary changes and the increased availability of lower-sodium foods.
