Brief Summary

To compare the effects of three levels of dietary sodium and two patterns of diet (a control diet and an intervention diet high in fruits, vegetables, and low fat dairy products and low in fat) on blood pressure in individuals with higher than optimal blood pressure or with Stage 1 hypertension.. DASH - Sodium built on and extended the results of the NHLBI-initiated Dietary Approaches to Stop Hypertension (DASH) study.
