I believe the research, without a single doubt, because the diet completely eliminated my hypertension without the need for drugs. In 2009, just before I started DASH diet at the recommendation of my doctor, my blood pressure was 170/90. I lost 90 pounds in 18 months with DASH diet/exercise. It made me younger on the inside! My blood pressure returned to normal and my hypertension has never returned. Hoping to keep it that way by sticking to the DASH diet for the rest of my life!
