How to Stop Hypertension?- DASH Diet

by | Feb 9, 2025 | Info | 0 comments

Dietary Approach to Stop Hypertension (DASH) Overview

The Dietary Approaches to Stop Hypertension (DASH) diet is recommended for people who want to prevent or treat high blood pressure and reduce their chance of developing heart disease. It focuses on fruits, vegetables, whole grains, and lean meats.

In fact, high blood pressure (hypertension) is a serious health concern linked to a higher chance of conditions such as heart disease, kidney failure, and stroke.

Accordingly, it affects nearly half of the world’s population. Although, the older you are, the higher your chance of developing it. However, it develops in more than 60% of people over age 60.

Consequently diet is thought to play a major role in the development of high blood pressure, scientists and policymakers have engineered specific dietary strategies to help reduce it. Therefore, this includes the DASH diet.

What is a DASH Diet?

In fact, the DASH diet was created after researchers noticed that high blood pressure was much less common in people who followed a plant-based diet, such as vegans and vegetarians. 

Therefore, that’s why the DASH diet emphasizes fruits and vegetables while containing lean protein sources like chiken, fish, and beans. Also, the diet is low in red meat, salt, added sugars, and fat.

Also, scientists believe that one of the main reasons people with high blood pressure can benefit from this diet is because it reduces salt intake to no more than 3/4 teaspoon (tsp) or 1,500 milligrams (mg) of sodium per day.

Benefits of DASH Diet

Beyond reducing blood pressure, the DASH diet offers a number of potential benefits:

  • Blood pressure: Numerous studies have found the DASH diet to be effective at reducing blood pressure.
  • Weight loss: A 2020 study found that following DASH containing at least 126 grams (g) of lean protein helped older adults over 65 with obesity reduce body fat. A 2023 study also suggests DASH can be helpful in lowering belly fat.
  • Cancer risk: A 2019 review found that people following the DASH diet had a lower risk of cancer, specifically breast, hepatic, endometrial, and lung cancer. Similar results were found in a study looking at colorectal cancer and DASH.
  • Metabolic syndrome risk: Research suggests that the DASH diet reduces your risk of metabolic syndrome by nearly 50%. Other research confirms there may be an inverse relationship between following DASH and the chance of developing metabolic syndrome.
  • Diabetes: The diet has been linked to a lower chance of diabetes. Research also demonstrates that it may improve insulin resistance as well.
  • Heart disease: A 2019 review found that following DASH may be linked to a lower chance of developing heart disease. Specifically, research suggests this diet may help lower various risk factors for heart disease, such as blood cholesterol, sugar, and fats.

In fact, many of these protective effects are attributed to the diet’s high fruit and vegetable content. In general, eating more fruits and vegetables can help reduce the chance of developing disease.


What to Eat in DASH Diet?

The DASH diet doesn’t list specific foods to eat. Instead, it recommends specific servings of different food groups.

Accordingly, you can adapt your current diet to the DASH guidelines by doing the following:

  • Eat more vegetables and fruits.
  • Cook with vegetable oils.
  • Swap refined grains for whole grains.
  • Choose fat-free or low fat dairy products.
  • Limit your intake of foods high added sugars, like soda and candy.
  • Choose lean protein sources like fish, poultry, and beans.
  • Limit your intake of foods high in saturated fats like fatty meats, full-fat dairy, and oils like coconut and palm oil.

Hence, the number of servings you can eat depends on how many calories you consume. Besides, below is an example of food portions based on a 2,000-calorie diet.


Whole Grains: 6-8 Servings Per Day

Examples of whole grains include whole-wheat or whole-grain bread, whole-grain breakfast cerels, brown rice, bulgur, quinoa, and oatmeal.

Examples of a serving include:

  • 1 slice of whole-grain bread
  • 1 ounce (oz) or 28 g of dry, whole-grain cereal
  • 1/2 cup (95 g) of cooked rice, pasta or cereal

Vegetables: 4–5 servings per day

In fact, all vegetables are allowed on the DASH diet.

Examples of a serving include the following:

  • 1 cup (about 30 g) of raw, leafy green vegetables like spinach or kale
  • 1/2 cup (about 45 g) of sliced vegetables, raw or cooked, like broccoli, carrots, squash or tomatoes

Fruits: 4–5 servings per day

Accordingly, if you’re following the DASH approach, you’ll be eating a lot of fruit. Hence, examples of fruits you can eat include apples, pears, peaches, berries,  and tropical fruits like pineapple and mango.

Examples of a serving include the following:

  • 1 medium apple
  • 1/4 cup (50 g) of dried apricots
  • 1/2 cup (30 g) of fresh, frozen or canned peaches

Dairy products: 2–3 servings per day

Also, dairy products on the DASH diet should be low in fat. Therefore, examples include skim milk, low-fat  cheese, and yogurt.

Examples of a serving include the following:

  • 1 cup (240 ml) of low fat milk
  • 1 cup (285 g) of low fat yogurt
  • 1.5 oz (45 g) of low fat cheese

Lean chicken, meat, and fish: 6 or fewer servings per day

Hence choosing lean cuts of meat and try to eat a serving of red meat only occasionally, no more than once or twice a week.

Therefore, examples of a serving include:

  • Cooked meat, chicken or fish 1 oz (28 g)
  • One Egg

Nuts, Seeds, and Legumes: 4–5 Servings per Week

Moreover, these include almonds, peanuts, hazelnuts, walnuts, sunflower seeds, flaxseeds, kidney beans, lentils, and split peas.

Furthermore, Serving examples include the following:

  • Nuts 1/3 cup (50 g)
  • Nut butter 2 tbsp (40 g)
  • Seeds 2 tbsp (16 g)
  • Cooked legumes 1/2 cup (40 g)

Fats and Oils: 2–3 Servings per Day

Additionally, the DASH diet recommends vegetable oils over other oils. Therefore, these include margarine and oils like canola, corn, olive, or safflower. It also recommends low fat mayonnaise and light salad dressing.

Furthermore, following are recommended intake :

  • 1 tsp (4.5 g) of soft margarine
  • 1 tsp (5 milliliters (ml)) of vegetable oil
  • 1 tsp (15 g) of mayonnaise
  • 2 tsp (30 ml) of salad dressing

Candy and Added Sugars: 5 or Fewer Servings per Week

Besides, added sugars, are kept to a minimum on the DASH diet, so limit your intake of candy, soda, and table sugar. The DASH diet also restricts unrefined sugars and alternative sugar sources, like agave nectar.

Examples of a serving include:

  • 1 tablespoon (tbsp) (12.5 g) of sugar
  • 1 tbsp (20 g) of jelly or jam
  • 1 cup (240 ml) of lemonade


Does DASH Diet works for Everyone

While studies on the DASH diet determined that the greatest reductions in blood pressure occurred in those with the lowest salt intake. However, the benefits of salt restriction on health and lifespan are not clear-cut.

Additionally, for people with high blood pressure, older adults, or non-white adults, reducing salt intake appears to significantly affect blood pressure. However, in people with lower blood pressure, white adults, or younger adults, the effects of reducing salt intake seem to be much smaller.

Hence, the theory that some people are more salt sensitive, meaning that salt exerts a greater influence on their blood pressure, could partly explain this.


Restricting Too Much Salt is Not Good For You

Eating too little salt has also been linked to health problems, such as an increased risk of heart disease, insulin resistance, and low blood sodium levels (hyponatremia).

In fact, the DASH diet recommends that people eat no more than 3/4 tsp (1,500 mg) of sodium per day.

However, one 2020 suggests that it’s unclear whether there are any benefits to reducing salt intake this low, and that the chance of heart disease begins to rise only after consuming more than 5,000 mg of sodium daily.

Therefore, this target can be achieved easily by reducing the amount of highly processed food in your diet and eating mostly whole foods.
