Can the DASH Diet help with high blood pressure?

Hypertension, also known as high blood pressure, is one of the major causes of premature death worldwide. Fortunately, it's preventable and manageable with medication, diet, and lifestyle changes. A meta-analysis published in Advances in Nutrition analyzed the results of thirty randomized-controlled trials. The results showed that the DASH eating plan significantly reduced blood pressure.

The DASH diet has developed with the help of The National Heart, Blood, and Lung Institute. It's a heart-healthy diet recommended by The American Heart Association, the 2015-2020 Dietary Guidelines for Americans, and the U.S. guidelines for treating high blood pressure.

Other DASH Diet benefits

The DASH diet may help to:

  • Reduce the risk of heart disease, heart failure, and stroke;
  • Prevent or manage type 2 diabetes;
  • Improve blood cholesterol levels;
  • Reduce the risk of kidney stones forming.

One of the most common questions about the DASH diet is, does it help with type 2 diabetes? The DASH diet may prevent or manage type 2 diabetes. The overall DASH diet consists of healthy eating patterns recommended for patients with glucose intolerance and Diabetes. It is rich in fiber and lean protein while low in calories and sugar.

However, if you have type 2 diabetes, healthy eating should be followed along with proper medications. Do not cut your medicines without your doctor's approval, and always consult your doctor before following a specific diet.

Possible health concerns on the DASH diet

The DASH diet is not restrictive. You can get all the nutrients you need by following the DASH diet. However, if you have a health problem or disease, we recommend talking to your doctor before starting any diet to lose weight.

The DASH diet is rich in fruits, vegetables, and whole grains, so you will consume a good amount of fiber. If you quickly increase your fiber intake, you may experience gastrointestinal discomfort. It is recommended to slowly increase fiber day by day to avoid gastrointestinal problems.

Tips to follow when on a DASH diet

If you want to follow the DASH eating plan, take your time to implement it for your daily nutrition. Here are a few tips:

  • Increase your vegetable and fruit consumption gradually by adding them to your lunch, dinner, or eating as snacks.
  • Increase fat-free or low-fat milk product consumption to three servings daily unless you have lactose intolerance.
  • Control your meat portions. Limit your lean meat consumption to 3 ounces a meal and to 6 ounces in a day. When you eat larger portions in a row, try to cut meat by half following a couple of days.
  • Make sure to eat two or more meatless, vegetarian-style meals each week.
  • Increase whole grains, brown rice, and bean servings.
  • When you'd like to have snacks or dessert, choose fruits and foods low in sugar, sodium, saturated, and trans fat. Examples of DASH-appropriate snacks are unsalted rice cakes, unsalted nuts and seeds, dry fruits, fat-free or low-fat yogurt, and raw vegetables.

Take prescribed medications

See your doctor for appropriate treatment if you suspect you have high blood pressure. If you've been given medication, take it as prescribed by your doctor. Remember, you'll still need to adopt a healthy diet and lifestyle to manage your blood pressure better.
