For centuries, olive oil has been a pantry staple and a symbol of healthy living, especially in Mediterranean cultures where it’s been used for everything from cooking to skin care. But in recent years, another rich, green oil has started making waves: avocado oil. It’s smooth, it’s versatile, and it has the kind of nutrient profile that gets nutritionists and chefs equally excited.
Both oils are celebrated for their potential heart benefits, but here’s the tricky part—they’re not exactly interchangeable, and their strengths shine in different ways. To find out which might be better for cardiovascular health, cardiologists and nutrition scientists have been weighing the evidence.
A Quick Look at How Each Oil Is Made
Olive oil comes from pressing whole olives, often using cold-press methods that avoid heat so more antioxidants are preserved. The best kind—extra virgin olive oil—is made from the first pressing, which produces a robust flavor and maximum nutrient retention.
Avocado oil is made by pressing the pulp of ripe avocados. Like olives, avocados are technically fruits, which means their oil is naturally rich in plant-based compounds. Avocado oil production has expanded rapidly over the past decade, partly because it can be extracted in large quantities without sacrificing quality.

The Heart-Friendly Perks of Avocado Oil
Once a niche cooking ingredient used mostly by health enthusiasts, avocado oil has now become a favorite in home kitchens and restaurants. Its neutral flavor works with almost any dish, and its high smoke point—around 480°F (250°C)—makes it ideal for frying, searing, and other high-heat cooking methods without producing harmful compounds.
1. Balances Cholesterol Levels
Avocado oil’s biggest selling point is its high content of monounsaturated fats—healthy fats also found in nuts, seeds, and olive oil. These fats are well known for helping reduce LDL (“bad”) cholesterol while raising HDL (“good”) cholesterol.
Early research has shown encouraging results. In one small study, swapping butter for avocado oil lowered both LDL and total cholesterol in people carrying extra weight. While this is promising, scientists note that larger, long-term studies are still needed to confirm the effects.
2. Loaded with Protective Antioxidants
Avocado oil contains tocopherols (a form of vitamin E), phytosterols, and carotenoids. These antioxidants fight oxidative stress, which occurs when harmful free radicals build up in the body and start damaging cells—including those in the heart and blood vessels.
The fact that avocado oil can handle high cooking temperatures without breaking down means it generates fewer damaging byproducts compared to some other oils. That’s an important advantage for anyone who regularly cooks with heat above 400°F.
3. May Help Regulate Blood Pressure
Animal studies and limited human research suggest avocado oil’s anti-inflammatory compounds may relax blood vessels, making it easier for blood to flow and potentially lowering blood pressure. While the strongest evidence so far comes from eating whole avocados, there’s reason to believe avocado oil could offer similar—if slightly milder—benefits.

The Timeless Benefits of Olive Oil
If avocado oil is the rising star, olive oil is the seasoned veteran with a resume that spans thousands of years. It has been part of human diets since ancient Greece and Rome, not just for flavor but also for medicinal purposes.
1. Rich in Polyphenols
Olive oil contains unique plant-based compounds called polyphenols, which act as powerful antioxidants. These include phenolic acids, secoiridoids, lignans, and flavones—all of which help combat inflammation and protect artery walls from damage.
Studies consistently show that people who consume more olive oil—especially extra virgin olive oil—have lower markers of inflammation. This is one reason why the Mediterranean diet, which features olive oil as its primary fat, is linked to a lower risk of heart disease.
2. Strong Evidence for Cholesterol Control
While avocado oil is still building its research portfolio, olive oil already has decades of high-quality studies backing its cholesterol benefits. Regular use has been linked to higher HDL levels, lower LDL levels, and reduced triglycerides, especially when used instead of butter, margarine, or shortening.
3. May Naturally Lower Blood Pressure
Olive oil’s combination of oleic acid and antioxidant compounds helps relax blood vessels, improving circulation. Multiple studies, including human trials, have shown modest but consistent blood pressure-lowering effects—particularly in people following a Mediterranean-style diet.
Avocado Oil vs. Olive Oil: The Nutritional Face-Off
| Nutrient (per tablespoon) | Avocado Oil | Olive Oil |
|---|---|---|
| Calories | ~120 | ~119 |
| Monounsaturated Fat | ~10 g | ~10 g |
| Polyunsaturated Fat | ~2 g | ~1.5 g |
| Saturated Fat | ~1.5 g | ~2 g |
| Smoke Point | ~480°F | ~375–410°F |
| Flavor | Mild, neutral | Rich, fruity |
| Best Uses | High-heat cooking, frying, baking | Dressings, low to medium-heat cooking, drizzling |
Both oils are calorically dense, so while they’re healthy fats, they should still be used in moderation—especially if you’re watching calorie intake.
How to Choose the Right Oil for the Job
- Go for Olive Oil when making salad dressings, dipping bread, drizzling over cooked vegetables, or lightly sautéing. Always choose cold-pressed, extra-virgin olive oil to get the maximum antioxidant benefit.
- Choose Avocado Oil for frying, roasting, or any cooking that involves high heat. It’s also a great choice for baked goods where you don’t want an overpowering flavor.
The Expert Verdict
Cardiologists generally give olive oil the edge for heart health—not because avocado oil is lacking, but because olive oil has been studied far more extensively and consistently shows benefits in large populations. In cultures where olive oil is a dietary staple, rates of heart disease tend to be lower, even when other lifestyle factors vary.
Still, avocado oil brings its own strengths to the table—especially its high smoke point and neutral flavor, which make it more versatile in certain recipes. Many nutrition experts suggest keeping both in your pantry and using each where it shines.

Final Takeaway
Think of these oils as two excellent tools in your heart-health toolkit. Olive oil is the time-tested classic, brimming with antioxidants and backed by decades of research. Avocado oil is the adaptable modern option, standing strong against high heat and bringing a smooth, gentle taste to any dish.
If you can, keep both on hand. That way, your kitchen stays ready for everything from a sizzling stir-fry to a fresh Mediterranean salad—while your heart reaps the benefits either way.
