Was ist die DASH-Diät?
The DASH diet - which stands for Dietary Approaches to Stop Hypertension - is a flexible eating plan that helps lower blood pressure (Bluthochdruck) and reduce your chances of Herzerkrankungen.
Developed over 20 years ago with support from the National Heart, Lung, and Blood Institute (NHLBI), this diet involves no special foods or strict plan. Instead, it puts emphasis on weekly nutritional goals, portion sizes, and eating a colourful variety of healthy foods including lots of vegetables and fruits.
DASH diet food list
Foods to include on the DASH diet and serving sizes based on a 2000 calories-per-day diet.
Foods to include | Daily/weekly servings | One serving size equals |
Vegetables - from all subgroups, including dark greens and starchy vegetables, such as kale and sweet potatoes | 4 to 5 a day | 75 grams (1 cup) of raw, leafy veg, or 85 grams (½ cup) of cooked vegetables |
Fruits - especially whole fruit skins, flesh, and pulp | 4 to 5 a day | 1 medium piece of fruit, or 75 grams (½ cup) of fresh or frozen fruit |
A variety of grains - at least half of which whole grains, such as brown rice and quinoa | 7 to 8 a day | 1 slice of wholemeal bread, or 125 grams (½ cup) of cooked brown rice or pasta |

Low-fat or fat-free dairy - including milk, yoghurt, and cheese | 2 to 3 a day | 235 millilitres (8 ounces) of milk, or 235 millilitres (1 cup) of yoghurt, or 45 grams (1 ½ cups) of cheese |

Alkohol | Up to 1 drink for women and men a day | Maximum 14 units a week 1.5 units is a small glass of wine 1 unit is 1/2 pint of 4% beer |
On the DASH diet, limiting your consumption of dietary salt, added Zucker, and unhealthy fats while focussing on healthy foods rich in lean protein, fibre, and minerals can help protect your heart and control your blood pressure.
This diet isn't just for people with high blood pressure or conditions that increase their chances of heart issues - anyone can benefit.
At the same time, you can tailor a DASH diet to suit your goals. For example, if you have high blood pressure - a reading of 135/85 or higher - and consume too much salt, the low-sodium DASH diet limits salt intake to no more than 1500 milligrams a day, which is three-quarters of a teaspoon. This is slightly lower than the one teaspoon of recommended salt intake per day - and it results in a substantially bigger drop in blood pressure.
There's nothing unusual about this eating plan. It's based on established gesunde Ernährung knowledge and portion guidelines, and for this reason is similar to many other health-promoting diets, such as the Mittelmeerdiät.
However, its emphasis on limiting salt has earned it a place among the top heart healthy diets.
Benefits of the DASH diet
Zurück zum InhaltLowers blood pressure
Your blood pressure is the force at which your blood travels around the body through your blood vessels. Having high blood pressure means that this force is placing a dangerous amount of strain on your heart to push out the blood - causing damage to your blood vessels, heart muscle, and other organs and increasing your chances of life-threatening heart problems.
By following the DASH diet, you can significantly lower your blood pressure within weeks - whether it's already dangerously high or at healthier levels.
Here's why:
Limits salt intake - salt pulls water into your bloodstream, increasing the force placed on blood vessel walls, raising blood pressure.
Limits added sugars - these can block the production of nitric oxide (NO) in blood vessels, a chemical that allows blood vessels to expand and reduce pressure.
Focusses on fruits and vegetables - which contain Kalium, which relieves tension in blood vessels and helps your body flush out more salt through your pee.
Lowers bad cholesterol
High levels of unhealthy Cholesterin - known to scientists as low-density lipoprotein (LDL) cholesterol - also increase your chance of heart problems, such as Herzerkrankungen und Schlaganfall. This is because LDL cholesterol, a fatty substance, can build up on your blood vessel walls, slow down blood flow, and prevent oxygen from reaching essential organs.
The DASH diet can significantly reduce the build-up of LDL cholesterol, and if fighting high cholesterol levels is your aim, adopting a higher-good fat, lower-carb version of the eating plan can be even more effective.
Here's why:
Limits saturated and trans fats - foods containing these types of fats raise LDL cholesterol in the blood.
Increases fibre - which slows digestion, keeping blood sugars from spiking, and prevents fats from being absorbed in the bloodstream.
Limits added sugars - which lowers high-density lipoprotein (HDL) cholesterol, the good cholesterol that helps flush other cholesterol out of the body.
A higher-fat DASH diet - as well as lowering LDL cholesterol, this modification of DASH also reduces triglycerides, fats that combined with high LDL cholesterol to increase your chances of heart issues.

Other potential benefits
Zurück zum InhaltThe DASH diet can benefit anyone, whether healthy or in poor heart health. But it may also help people with particular health conditions or goals.
Zum Beispiel:
Diabetes management - lowering blood pressure is an important goal for people with Diabetes. What's more, it could also improve insulin resistance, cholesterol, and weight management - all of which help to either manage or reverse diabetes.
Healthy weight loss - given that the DASH diet cuts down on high-fat and sugary foods, some people can reach a healthy weight on the DASH diet, so long as they’re creating calorie deficit.
Lowering the chance of cancer - following this diet may lower your chance of getting some cancers, including kolorektales Karzinom und Brustkrebs.
Lowering the chance of metabolic syndrome - the DASH diet may reduce your chance of developing Metabolisches Syndrom by up to 81%.

Häufig gestellte Fragen
What kind of foods should I prioritise on the DASH diet to get the most benefit?
The DASH diet encourages a variety of healthy foods. You should focus on including lots of vegetables and fruits, especially whole fruits. Whole grains, lean meats, poultry, and fish, as well as low-fat dairy products, nuts, seeds, and beans are also important. These foods are rich in fibre, lean protein, and essential minerals.
How does the DASH diet compare to other diets like the Mediterranean diet?
The DASH diet is similar to many other health-promoting diets, such as the Mediterranean diet, because it is based on established healthy eating knowledge and portion guidelines. Its unique emphasis on limiting salt, however, has made it one of the top diets for heart health.
Can the DASH diet help me if I have diabetes?
Yes, the DASH diet can be beneficial for people with diabetes. It helps lower blood pressure, which is an important goal for managing diabetes. Additionally, it may improve insulin resistance, cholesterol levels, and weight management, all of which contribute to managing or potentially reversing diabetes.
Is there a specific way the DASH diet helps lower my blood pressure?
The DASH diet helps lower blood pressure by limiting salt intake, which prevents water from increasing pressure on blood vessel walls. It also limits added sugars that can block chemicals needed for blood vessels to expand. Furthermore, its focus on fruits and vegetables provides potassium, which helps relax blood vessels and flush out excess salt.
What is the specific recommendation for salt intake if I have high blood pressure?
If you have high blood pressure (readings of 135/85 or higher) and consume too much salt, the low-sodium DASH diet recommends limiting salt intake to no more than 1500 milligrams per day. This amount is equivalent to three-quarters of a teaspoon and can lead to a significant drop in blood pressure.
How does the DASH diet specifically address 'bad' cholesterol?
The DASH diet lowers 'bad' low-density lipoprotein (LDL) cholesterol by limiting saturated and trans fats, which are known to raise LDL levels. It also increases fibre intake, which helps prevent fats from being absorbed. Limiting added sugars is also beneficial as they can lower 'good' high-density lipoprotein (HDL) cholesterol.
Can embracing the DASH diet help me achieve a healthy weight?
Yes, the DASH diet can help some people achieve a healthy weight. This is because the diet cuts down on high-fat and sugary foods. By creating a calorie deficit while following the DASH guidelines, weight loss can occur.
