Best Diet for High Blood Pressure: What to Eat and Avoid?

Diet plays a critical role in managing high blood pressure (hypertension). The foods you eat can directly affect your blood vessels, heart function, and overall cardiovascular health.

By following a balanced, heart-healthy diet, many people can lower their blood pressure naturally and reduce the risk of long-term complications.

Why Diet Matters for Blood Pressure

What you eat influences how your body regulates blood pressure. A poor diet—especially one high in sodium and processed foods – can increase pressure on your arteries.

On the other hand, a balanced diet supports:

• Healthy blood vessels
• Better circulation
• Reduced cardiovascular strain
