The Dash Diet Can Help With High-Blood Pressure

WHAT IS DASH?

The Dietary Approaches to Stop Hypertension (DASH) diet was developed by the US National Institutes of Health, as a life-long approach to heart-healthy eating. DASH recommends eating plenty of vegetables, fruits, whole grains, fat-free or low-fat dairy products, fish, poultry, beans, nuts, and vegetable oils; limiting foods high in saturated fat (such as processed meat, full-fat dairy products, and tropical oils such as coconut and palm oils); and limiting sugar-sweetened beverages and sweets. DASH also recommends a maximum daily sodium intake of 2300 mg.

HEALTH BENEFITS OF THE DASH DIET

Research has shown that DASH offers an effective nutritional approach towards prevention and treatment of high-blood pressure (hypertension), which is a major risk factor for heart disease and stroke. A trial showed that reducing sodium intake even further to 1500 mg per day (lower sodium DASH diet) may provide additional benefits in terms of lowering blood pressure even further than the standard DASH diet described above. Furthermore, in a clinical trial of diabetic patients over eight weeks, this diet was associated with reduced cardiometabolic risk measurements, specifically weight, waist circumference and cholesterol levels. With the scientifically proven health benefits this diet offers, and being very much in line with current dietary recommendations in Europe, DASH is a balanced dietary strategy that could be adopted to achieve a healthier diet and lifestyle. 

 

FOOD RECOMMENDATIONS

To support people following this diet, DASH provides a recommended daily or weekly number of servings across different food groups to achieve a standard 2000 kilocalories energy intake per day (Table 1). The diet is flexible as the number of servings of different foods can be easily adjusted to meet the specific energy needs of the individual by taking into account desired weight changes and physical activity levels.
