DASH: A Heart-Healthy Diet
Approximately 1 in 4 adults in the United States has high blood pressure – also known as “ hypertension” – which increases the risk of heart disease. Lifestyle changes for controlling blood pressure have usually included:
- losing weight
- increasing physical activity
- reducing sodium intake
- limiting alcoholic beverages to 2 drinks a day.
Although these strategies are still recommended, is there a specific diet for lowering blood pressure?

The DASH Study
The DASH study – for “Dietary Approaches to Stop Hypertension study“ – tested a diet, and the findings were impressive. The blood pressure of persons who followed the DASH diet decreased within days, even in persons with normal blood pressure. In those persons with high blood pressure, the decrease in blood pressure was comparable to that found with some medications.
What is the DASH diet?
The DASH diet is a healthy diet that is:
- total fat
- saturated fat
moderately high in:
A follow-up study tested the DASH diet with different levels of sodium. The overall finding was that the DASH diet with a sodium restriction helps to lower blood pressure even more than the DASH diet without a sodium restriction.
How do I follow a DASH, sodium-restricted diet?
The diet is fairly easy to follow. For most, it means:
increasing your servings of:
- low-fat dairy products
- whole grains
- nuts in your diet
- red meat
- added fats
- sweets in your diet.

Limit your intake of meat to 2 servings per day.
- A serving is 3 ounces, which is the size of a deck of cards.
Have 4-5 servings each week of:
- Limit foods that are cured – such as bacon and ham.
- Limit foods packed in brine – such as pickles or sauerkraut.
Limit condiments, such as:
- barbeque sauce.
Instead of salt, flavor foods with:
