Avocado oil is one of the more heart-friendly cooking oils you can use. Its fat profile is dominated by oleic acid, the same monounsaturated fat that gives olive oil its well-documented cardiovascular benefits. Roughly 37 to 65% of avocado oil’s fatty acids are monounsaturated, with saturated fat making up less than 30%. The American Heart Association lists avocado oil among healthy cooking oil choices.
What Makes the Fat Profile Heart-Friendly
The star player in avocado oil is oleic acid, a monounsaturated fatty acid. Oleic acid helps improve how blood vessels function, reduces inflammation, and supports insulin sensitivity, all of which matter for long-term cardiovascular health. After oleic acid, the next most abundant fat is palmitic acid (a saturated fat at roughly 20 to 29%), followed by linoleic acid (a polyunsaturated fat at about 8 to 15%).
The AHA recommends choosing oils with less than 4 grams of saturated fat per tablespoon and no trans fats. Avocado oil fits comfortably within those guidelines. It also provides vitamin E, an antioxidant that helps protect cells from the kind of oxidative damage that contributes to heart disease.
Effects on Cholesterol and Blood Pressure
Monounsaturated fats in general tend to lower LDL (“bad”) cholesterol when they replace saturated fats in your diet. Avocado oil works through a few additional mechanisms: it contains plant sterols (compounds structurally similar to cholesterol that compete with cholesterol for absorption in the gut), which can further improve your lipid profile.
On the blood pressure side, animal research has shown meaningful results. In one study on hypertensive rats, avocado oil decreased diastolic blood pressure by about 21% and systolic blood pressure by about 15%. Human data on avocado consumption (the whole fruit, not isolated oil) is also encouraging. A large study of Mexican women found that eating five or more servings of avocado per week was associated with a 17% lower rate of developing high blood pressure compared to non-consumers or low consumers.
Inflammation and Metabolic Health
Chronic inflammation is a driving force behind atherosclerosis, the buildup of plaque in your arteries. Avocado oil appears to dial down several inflammatory pathways. In a study on obese mice, supplementing with avocado oil reduced levels of key inflammatory signals in fat tissue and muscle. The same study found that avocado oil improved insulin sensitivity, lowered blood triglycerides, and reduced fat accumulation in the liver.
These metabolic improvements matter because insulin resistance and high triglycerides are independent risk factors for heart disease. When your body handles insulin more efficiently, it’s better at regulating blood sugar and storing fat appropriately, which reduces the strain on your cardiovascular system over time. The mice in the study also showed lower levels of oxidative stress markers across multiple tissues, paired with increased activity of the body’s own antioxidant enzymes.
How Avocado Oil Compares to Olive Oil
Avocado oil and extra virgin olive oil are nutritional cousins. Both are rich in monounsaturated fats, both contain antioxidants, and both have been linked to reduced inflammation, lower LDL cholesterol, and improved blood vessel function. The main practical difference is in the kitchen: refined avocado oil has a smoke point around 500°F, while extra virgin olive oil tops out around 350 to 375°F. That makes avocado oil a better fit for high-heat cooking like stir-frying, searing, or roasting at high temperatures.
Virgin (unrefined) avocado oil has a lower smoke point of 350 to 375°F, similar to olive oil. It retains more of its natural color and flavor, making it a good choice for dressings and low-heat cooking. Olive oil has a larger body of long-term human research behind it, particularly from Mediterranean diet studies. But from a fat composition standpoint, avocado oil offers comparable heart benefits.
How to Use It for the Most Benefit
The heart benefits of avocado oil come from using it in place of less healthy fats, not in addition to them. Swapping out butter, lard, or coconut oil for avocado oil in your cooking is one of the simplest dietary changes you can make for cardiovascular health. A tablespoon or two per day in cooking or salad dressings is a reasonable amount that aligns with general guidance on healthy fat intake.
When buying avocado oil, look for products labeled “100% avocado oil” from brands that are transparent about sourcing. Independent testing has found that some avocado oils on the market are diluted with cheaper oils or have gone rancid before purchase. Choosing refined avocado oil from a reputable brand gives you a neutral-flavored, high-heat stable oil. Choosing virgin avocado oil gives you more of the natural antioxidants but with a lower smoke point and a mild avocado flavor.
Store it in a cool, dark place. Like all unsaturated oils, avocado oil can oxidize over time, which degrades both its flavor and its health benefits. Using it within a few months of opening is a good rule of thumb.
