What is the DASH diet for high blood pressure?
Last updated September 3, 2026.
DASH (Dietary Approaches to Stop Hypertension) is the NIH-tested eating plan for blood pressure: vegetables, fruit, whole grains, low-fat dairy, fish, beans, and nuts, with sodium capped at 2,300 mg, or 1,500 mg for the stronger version. It loads potassium, magnesium, calcium, protein, and fiber while limiting fatty red meat, full-fat dairy, tropical oils, and sweets. The trial results are why doctors keep prescribing it: roughly 5 to 11 points off systolic pressure, largest in people who already had hypertension, and bigger still when DASH combines with sodium restriction. Cholesterol and overall cardiovascular risk improve alongside. Starting it does not require a program or a dietitian: half the plate vegetables and fruit, whole grains over refined, low-fat dairy, unsalted nuts instead of processed snacks, more home cooking, and label checks for sodium. It pairs with every other intervention rather than replacing them, so people on medication keep taking it while the diet makes the numbers easier to control. The plan is not a cleanse or a phase; it works as a permanent pattern, which is exactly what blood pressure management needs.
What to do
- Half the plate: vegetables and fruit at every meal.
- Swap, do not suffer: whole grains, low-fat dairy, unsalted nuts over processed snacks.
- Cap sodium: 2,300 mg daily standard, 1,500 mg for the stronger effect.
- Read labels: sodium hides in bread, sauces, and packaged food.
- Keep your medication: DASH adds to treatment; it does not replace it without your clinician's say.
