The DASH diet is a healthy eating plan specific for treating and preventing high blood pressure. It stands for Dietary Approaches to Stop Hypertension.  

Foods included in the DASH diet are extremely rich in particular nutrients that help to control blood pressure, such as calcium, magnesium, and potassium. It also encourages limited to no foods high in added sugar, salt, and saturated fat.  

The DASH diet is very effective[1] and can decrease a person’s blood pressure in just two weeks. Furthermore, it can reduce[2] one’s low-density lipoprotein (LDL or “bad”) cholesterol and triglyceride levels which is essential if you are worried about heart disease and stroke, as high LDL cholesterol levels are a significant risk factor for these.

DASH Diet Eating Plan For High Blood Pressure

This plan focuses on reducing sodium intake while emphasizing nutrient-rich foods like fruits, vegetables, whole grains, lean protein, and low-fat dairy.

What Is The DASH Diet?

The DASH diet is more of a lifestyle change than a diet. It focuses on flexibility and balance and thus helps to create heart-healthy habits that are sustainable in the long term. In addition, it uses foods that can be found in every grocery store and is easy to follow.

The National Heart, Blood, and Lung Institute helped develop the DASH diet. They created the diet after researchers found that vegans and vegetarians had significantly lower blood pressure than their carnivore peers. Therefore, they formed a diet rich in fruits, vegetables, and whole grains. It also includes low-fat dairy foods, chicken, fish, nuts, seeds, and beans. Intake of other foods such as salt-added sugars, full-fat dairy products, and fatty meats is discouraged.  

The main driving force behind the benefit of this diet for people with hypertension is thought to be lowering sodium intake.[3] This diet does not allow more than one teaspoon of salt daily. One teaspoon is equal to approximately 2300 mg of sodium. These recommendations mimic the Dietary Guidelines for Americans put out by the United States Department of Agriculture. 

Benefits Of The DASH Diet

Along with helping those who suffer from hypertension, the DASH diet can provide numerous health benefits, including decreasing your risk of cancer and even helping with weight loss.   

The DASH diet can benefit your health in the following ways:

Lower Blood Pressure

An individual’s blood pressure[4] is the pressure exerted by blood against the walls of their arteries. Blood pressure is measured with two different numbers: 

  • The first number (systolic blood pressure): The pressure (in millimeters of mercury, or mmHg) exerted against the walls of your arteries from the force of a heartbeat
  • The second number (diastolic blood pressure): The force remaining against the walls of your arteries in between heartbeats; a measure of peripheral vascular resistance

When documenting blood pressure readings, the systolic number is placed above the diastolic pressure number. Normal blood pressure is described as one less than 120/80 mmHg (119/79 or lower). Fascinatingly, the DASH diet has shown[5] lowered blood pressure in not only people with high blood pressure but also in people with healthy blood pressure levels.  

On average, research has proven that using the DASH diet as the only intervention for reducing blood pressure can lower systolic blood pressure by 6 to 11 mm Hg. Furthermore, the DASH diet has been shown[6] to not only decrease blood pressure but also lower the risk of heart attack, stroke, obesity, and diabetes.

Weight Loss

You can shed a few pounds as an added perk of following the DASH diet. Losing weight is a bonus for normalizing blood pressure, and most people with hypertension are encouraged to lose weight for this very reason. Generally, your blood pressure tends to be higher if you weigh more.  

Many studies have shown that along with exercise,[7] the DASH diet can help you lose weight. Of note, the study participants also followed a calorie restriction, meaning they ate fewer calories than they burned throughout the day.  

Given this information, there is evidence that more than adapting the DASH diet is needed to promote weight loss. Thus, the DASH diet combined with exercise and calorie reduction is a great way to lose weight. 

Cancer Prevention

Another benefit of following the DASH diet is the fact that it may have anti-cancer properties. For example, a study[8] published in July 2020 showed that women who adhered to the DASH diet had a lower likelihood of developing breast cancer. In addition, a meta-analysis study[9] performed in 2020 showed that adherence to the DASH diet was associated with a lower risk of colorectal cancer. 

Healthier Gut Microbiome

We are only now learning the positive impact on health that comes from a healthy gut[10] and a favorable balance of good intestinal bacteria, from the aforementioned weight loss, cancer prevention, and heart health to discouraging the onset of insulin resistance and diabetes.

Potential Downsides

The DASH diet, while beneficial for some people, can also have its potential downsides, such as

Meal Planning

The DASH diet plan involves a lot of planning and forethought because of the promotion of fresh fruits, vegetables, and whole grains. This is quite a lifestyle change if you are not used to following or preparing meal plans and cooking most of your meals. In that case, the DASH diet will require you to consider your food choices and possibly obtain guidance from a registered dietitian or another medical professional.  

Questionable Foods

Some foods allowed on the DASH diet are unhealthy and may not be appropriate to ward off heart disease and other adverse health effects. 

For example, pretzels are an approved food choice and come from the grain group even though they contain hardly any fiber or nutrition. (Salted pretzels, well, you can imagine.) Frozen yogurt is another questionable food because while it is deemed acceptable, it is typically loaded with sugar. Lastly, cereals are a generally allowed food even though multiple kinds of cereal are incredibly high in sugar and low in fiber and other nutrients.    

Gastrointestinal Distress

The DASH diet tends to be very high in fiber due to the high fruit and vegetable consumption. Therefore, some people not used to high fiber may find the sudden increase gives them an upset stomach through bloating and gas. You can help fight off these negative impacts by slowly adding high-fiber foods over several weeks rather than all at once.

Specific foods aren’t listed in the DASH diet. Instead, it gives the serving sizes you should have for each food group. Your calorie levels determine the number of servings allowed in each group.
