What is DASH Diet?
Short for Dietary Approaches to Stop Hypertension
An NIH-designed pattern for lowering blood pressure — fruit, vegetables, whole grains, low-sodium.
DASH (Dietary Approaches to Stop Hypertension) is an NIH-designed eating pattern built originally to lower blood pressure without drugs. The pattern: fruit, vegetables, whole grains, lean protein, low-fat dairy, and a sodium cap around 1,500 to 2,300 mg/day. Over time the same pattern showed real weight-loss and cardiovascular benefits.
Quick definition
DASH started as a 1990s NHLBI clinical-research project. It's been ranked the best diet for blood pressure (and frequently best overall) by U.S. News & World Report's annual panel for over a decade running.
How it actually works
The original DASH trial (Appel et al., 1997, NEJM) tested three diets: typical American, fruits-and-vegetables-only, and the full DASH pattern. Full DASH dropped systolic blood pressure by 11.4 mmHg in hypertensive subjects — comparable to a single-drug intervention. Adding sodium restriction (DASH-Sodium, 2001) dropped it further.
For weight, DASH is naturally lower in calorie density than standard Western eating, so people eat less without trying. It overlaps significantly with the Mediterranean pattern — vegetables, whole grains, lean proteins — with two differences: DASH explicitly emphasizes low-fat dairy, and Mediterranean leans more on olive oil and seafood.
Daily DASH targets: 4 to 5 servings each of fruits and vegetables, 6 to 8 grains (mostly whole), 6 or fewer 1-oz lean protein servings, 2 to 3 dairy, 4 to 5 nut/seed/legume servings per week, 5 sweets per week max.
Why it matters for weight loss
If you have hypertension, prediabetes, or a family history of cardiovascular disease, DASH is the most-evidenced pattern for managing those conditions while also producing modest weight loss. The NIH publishes free DASH meal plans you can print and shop from.
Common misconceptions
The biggest myth: DASH is just "eat less salt." Sodium reduction is a piece, but the full pattern matters more than the sodium cap alone. Just cutting salt without adding produce produces about half the effect.
The second myth: DASH requires expensive food. It doesn't. Frozen vegetables, dried beans, oatmeal, eggs, and chicken thighs satisfy the pattern cheaply. The expensive groceries are optional, not required.
