Hypertension — high blood pressure — is called the 'silent killer' because it often causes no symptoms while silently damaging the heart, kidneys, and brain. Over 45% of Pakistani adults over 45 have hypertension, yet many are unaware.
How Blood Pressure Works
Blood pressure is the force your blood exerts on artery walls. A reading of 120/80 mmHg is ideal. Above 130/80 is elevated, and above 140/90 is hypertension. Consistently high pressure strains the heart and progressively damages blood vessels throughout the body.
Salt: The Partial Truth
Yes, sodium (found in salt) causes the body to retain water, increasing blood volume and pressure. But the relationship is more nuanced. Potassium counteracts sodium — and most people are deficient in potassium, not just high in sodium. This imbalance is often more important than sodium alone.
The DASH Diet — Clinically Proven for Hypertension
The Dietary Approaches to Stop Hypertension diet is one of the most well-researched dietary approaches in medicine. Key principles:
- Abundant fruits and vegetables (high in potassium, magnesium)
- Low-fat dairy
- Whole grains over refined carbs
- Limited red meat
- Very limited added salt, saturated fat, and sugar
Pakistani Foods That Help Lower Blood Pressure
- Bananas — rich in potassium
- Spinach and palak — magnesium powerhouse
- Dahi (plain yoghurt) — calcium reduces arterial stiffness
- Garlic (lehsan) — allicin in garlic has documented BP-lowering effects
- Watermelon — contains citrulline which relaxes blood vessels
- Dark chocolate (70%+) — in small amounts, flavonoids improve circulation
What to Reduce
Salty pickles (achaar), papad, processed meats, canned foods, soy sauce, and adding extra salt at the table are the highest contributors to sodium load in Pakistani diets.
