Why Heart-Healthy Foods Matter

Your heart works around the clock to pump blood throughout your body. To perform efficiently, it requires nutrients that support healthy blood vessels, maintain normal blood pressure, and reduce harmful cholesterol.

A heart-friendly diet helps:

• Lower LDL (bad) cholesterol

• Increase HDL (good) cholesterol

• Control blood pressure

• Reduce inflammation

• Improve blood circulation

• Maintain a healthy body weight

• Reduce the risk of heart attacks and strokes

Choosing nutritious foods consistently can have a greater long-term impact than relying on medications alone for prevention.
