It recommends reducing sodium, foods and beverages with added sugars, and red meat. The results of this landmark study contributed much of the scientific basis for the Dietary Guidelines for Americans 2010 and later editions.ĭASH is based on the following foods: fruits, vegetables, low fat milk, whole grains, fish, poultry, beans, and nuts. The reduction of blood pressure in the DASH combination diet was comparable to that of people on medication for stage 1 hypertension. Those with hypertension showed greater decreases in blood pressure than those without hypertension. ĭespite no weight changes, the combination diet reduced blood pressure more than the other two diets. All three diets provided about 3000 mg sodium, which is more than the recommended amount from the Dietary Guidelines for Americans but less than the average sodium intake for Americans. The last two diets were richer in nutrients associated with lower blood pressure, such as potassium, magnesium, calcium, fiber, and protein. Three diets were tested: 1) a control diet, or a standard American diet, 2) a fruits and vegetables diet, similar to the control diet but providing more fruits and vegetables and less snacks and sweets, and 3) a combination diet rich in fruits, vegetables, nuts, and low-fat dairy foods with reduced amounts of saturated fat, total fat, and cholesterol. The authors surmised that eating a diet with many different foods with blood pressure-lowering nutrients would show a greater effect on blood pressure than eating single nutrients, such as found in supplements or in a limited diet.

The DASH trial randomly assigned 456 people to different diets to test the effects of dietary patterns on lowering blood pressure. ĭASH was first introduced at a meeting of the American Heart Association in 1996 and later published in the New England Journal of Medicine in 1997. Untreated high blood pressure can lead to heart disease, stroke, congestive heart failure, kidney disease, and blindness. It will normally vary throughout the day but if it remains too high, this is called high blood pressure or hypertension. Blood pressure is the amount of pressure that blood places against the walls of arteries. The DASH (Dietary Approaches to Stop Hypertension) diet is sometimes prescribed by doctors to help treat high blood pressure.
