This year marks the 20th anniversary of the publication showing the blood pressure–lowering effects of the Dietary Approaches to Stop Hypertension (DASH) diet.1 The DASH diet is considered an important advance in nutritional science. It emphasizes foods rich in protein, fiber, potassium, magnesium, and calcium, such as fruits and vegetables, beans, nuts, whole grains, and low-fat dairy. It also limits foods high in saturated fat and sugar.1 DASH is not a reduced-sodium diet, but its effect is enhanced by also lowering sodium intake.1 Since the creation of DASH 20 years ago, numerous trials have demonstrated that it consistently lowers blood pressure across a diverse range of patients with hypertension and prehypertension.
