Understanding Hypertension and the Role of Diet
Hypertension — commonly known as high blood pressure — affects millions of people worldwide and is a leading risk factor for heart disease and stroke. While medication and medical supervision play an important role in management, lifestyle factors, particularly diet, are widely recognised as foundational to long-term blood pressure support.

Key Dietary Principles for Blood Pressure Support
Research consistently highlights several dietary patterns associated with healthier blood pressure levels. The most well-studied is the DASH diet (Dietary Approaches to Stop Hypertension), which emphasises:
- Fruits and vegetables (aim for 8–10 servings daily)
- Whole grains over refined carbohydrates
- Low-fat dairy or dairy alternatives
- Lean proteins such as fish, poultry, legumes, and nuts
- Reduced sodium intake (ideally under 2,300 mg per day, with 1,500 mg as a further target for some individuals)
- Limited saturated fats, added sugars, and alcohol
Foods to Prioritise
Certain foods are particularly associated with cardiovascular and blood pressure support:
- Leafy greens (spinach, kale, Swiss chard) — rich in potassium, which helps the kidneys excrete sodium
- Berries — contain flavonoids linked to improved vascular function
- Oats and whole grains — provide fibre that supports heart health
- Fatty fish (salmon, mackerel, sardines) — high in omega-3 fatty acids
- Bananas and avocados — excellent sources of potassium and healthy fats
- Garlic and herbs — used in traditional wellness practices and studied for cardiovascular benefits
- Unsalted nuts and seeds — provide magnesium and healthy fats
Foods to Limit
- High-sodium processed foods, canned soups, and ready meals
- Deli meats and cured products
- Sugary beverages and desserts
- Excessive caffeine and alcohol
- Saturated and trans fats found in fried and ultra-processed foods
