Heart disease remains a leading cause of death worldwide, but the good news is that diet plays a major role in prevention. By making smart food choices, you can significantly reduce your risk of high blood pressure, high cholesterol, and other factors that harm heart health. This guide outlines the key dietary recommendations from health organizations like the World Health Organization (WHO) and the American Heart Association.
Key Nutrients for a Healthy Heart
A heart-healthy diet isn’t about strict deprivation; it’s about a balance of nutrients that support your cardiovascular system.
- Potassium: Helps to lower blood pressure by counteracting the effects of sodium.
- Fiber: Found in whole grains, fruits, vegetables, and legumes, fiber can help lower bad (LDL) cholesterol.
- Omega-3 Fatty Acids: These healthy fats can reduce inflammation and lower the risk of heart disease.
- Unsaturated Fats: Found in plant-based oils and nuts, these fats can improve cholesterol levels and are a healthier alternative to saturated and trans fats.

| Saturated & Trans Fats | These fats increase bad cholesterol levels and can lead to plaque buildup in your arteries. Trans fats, in particular, should be avoided entirely. | Reduce consumption of fatty red meat, butter, and cheese. Check labels for "partially hydrogenated oils," a common source of trans fat. |
| Added Sugars | Excess sugar intake is linked to obesity, inflammation, and high blood pressure, all of which strain the heart. | Cut back on sugary drinks, candy, and pastries. Choose desserts in moderation. |
