What is the DASH Diet?
DASH stands for Dietary Approaches to Stop Hypertension. It is a well-researched, evidence-based eating plan specifically designed to lower blood pressure and improve overall heart health. Developed by the National Institutes of Health, the DASH diet has consistently been ranked as one of the best overall diets in the world.
Unlike many restrictive diets, the DASH diet is not about cutting entire food groups. Instead, it focuses on eating more of the foods that naturally lower blood pressure and reducing foods that raise it.
What to Eat on the DASH Diet
Foods to Eat More Of
✅ DASH-Friendly Foods
- Fruits: Bananas, berries, oranges, apples — rich in potassium and antioxidants
- Vegetables: Spinach, broccoli, carrots, sweet potatoes — high in fibre and minerals
- Whole grains: Brown rice, oats, whole wheat bread — provides sustained energy
- Lean proteins: Fish, skinless chicken, beans, lentils
- Low-fat dairy: Skimmed milk, low-fat yoghurt — good sources of calcium
- Nuts and seeds: Almonds, flaxseeds, sunflower seeds — healthy fats
Foods to Reduce
❌ Limit These Foods
- High-sodium processed foods and ready meals
- Red meat and full-fat dairy products
- Sugary drinks, sweets, and desserts
- Saturated and trans fats
- Alcohol — especially more than one drink per day
Why the DASH Diet Works
The DASH diet works because it is rich in potassium, calcium, and magnesium — three minerals that are scientifically proven to help lower blood pressure. It is also naturally low in sodium, saturated fat, and added sugars, all of which contribute to high blood pressure when consumed in excess.
Research has shown that people following the DASH diet can reduce their systolic blood pressure by up to 11 mmHg, which is comparable to the effect of some blood pressure medications.
How to Start the DASH Diet
- Gradually replace white bread and pasta with whole grain alternatives
- Add one extra serving of vegetables to your meals each day
- Choose low-fat or fat-free dairy products
- Swap processed snacks for a handful of unsalted nuts or fresh fruit
- Read food labels and choose products with less than 140mg of sodium per serving
- Cook at home more often to control ingredients
💡 Remember: You do not have to change everything at once. Small, consistent changes over time make a big difference to your blood pressure and overall health.
