Heart-Healthy Oils: Best Choices for Lowering Cholesterol and Supporting Cardiovascular Health

When it comes to cooking and eating for a strong heart, not all oils are created equal. Heart-healthy oils, fats that support cardiovascular function by reducing bad cholesterol and inflammation. Also known as cardiovascular-friendly fats, these oils are the kind your doctor recommends—not because they’re trendy, but because decades of research show they help keep arteries clear and blood pressure steady. The difference between a heart-healthy oil and one that might hurt you isn’t just about calories—it’s about the type of fat, how it affects your LDL and HDL, and whether it fights inflammation or fuels it.

One of the most studied olive oil, a monounsaturated fat rich in antioxidants like oleocanthal that reduce arterial inflammation. Also known as extra virgin olive oil, it’s been linked to lower rates of heart disease in Mediterranean populations who use it daily for cooking and dressings. Then there’s avocado oil, a high-heat stable oil with similar benefits to olive oil, plus plant sterols that help block cholesterol absorption. Also known as avocado fat, it’s a great swap for butter or vegetable oil in sautés and baking. Don’t overlook omega-3 fatty acids, essential fats found in flaxseed, chia, and walnut oils that reduce triglycerides and lower the risk of arrhythmias. Also known as ALA fats, they’re not made by your body—you have to get them from food or supplements. These aren’t magic bullets, but they’re the closest thing to dietary medicine for your heart.

What about coconut oil? It’s popular, but the science doesn’t back it as a heart-healthy choice. It’s mostly saturated fat, which raises LDL—the bad cholesterol—more than most other oils. Same goes for palm oil and hydrogenated oils. Even if a product says "natural," that doesn’t mean it’s good for your arteries. Stick with oils that come from plants, are minimally processed, and come with evidence, not marketing.

When you choose a heart-healthy oil, you’re not just picking a cooking ingredient—you’re making a daily choice that adds up. Swapping out butter for olive oil on toast. Using avocado oil instead of canola in your stir-fry. Drizzling flaxseed oil on your salad instead of a creamy dressing. These small shifts, done consistently, change your blood markers over time. You won’t see results overnight, but in a year? You might notice your cholesterol numbers moving in the right direction, your energy improving, and your doctor nodding in approval.
