A comprehensive meta-analysis published in Advances in Nutrition analyzing 30 randomized controlled trials involving 5,545 participants provides compelling evidence that the Dietary Approaches to Stop Hypertension (DASH) diet delivers significant blood pressure benefits for both hypertensive and normotensive adults. The systematic review found that the DASH diet reduced systolic blood pressure by an average of 3.2 mm Hg and diastolic blood pressure by 2.5 mm Hg, with enhanced benefits in specific populations including those with higher sodium intake (>2,400mg daily), younger adults under 50 years, and untreated hypertensive patients. While these reductions may seem modest, research demonstrates that even small blood pressure reductions translate to meaningful cardiovascular benefits at the population level, supporting the DASH diet as a first-line lifestyle intervention for blood pressure management, a complementary approach alongside medication for treated hypertension, and a preventive strategy for individuals with normal blood pressure.
