Heart disease is a leading cause of death worldwide, but the good news is that many risk factors are preventable. One of the most powerful ways to protect your heart is through proper nutrition. A heart-healthy diet can reduce cholesterol levels, lower blood pressure, prevent inflammation, and improve overall cardiovascular health. In this guide, we will explore the best dietary strategies to reduce your risk of heart disease.
Understanding Heart Disease and Its Risk Factors
Heart disease, also known as cardiovascular disease (CVD), encompasses conditions such as coronary artery disease, heart attacks, and strokes. Common risk factors include:
- High blood pressure

While genetics play a role, lifestyle choices, particularly diet, have a significant impact on heart health.
