Avocado oil and olive oil are remarkably similar in nutritional profile. Tablespoon for tablespoon, they contain nearly identical amounts of monounsaturated fat, the type most strongly linked to heart health. The real differences between them come down to smoke point, antioxidant content, and a serious quality-control problem with avocado oil that most shoppers don’t know about.
Fat Profiles Are Nearly Identical
The core reason both oils are considered healthy is the same: they’re dominated by oleic acid, a monounsaturated fat associated with lower LDL cholesterol and reduced inflammation. Per tablespoon, avocado oil delivers 9.88 grams of monounsaturated fat compared to olive oil’s 9.86 grams. That’s essentially a tie.
Avocado oil has slightly more polyunsaturated fat (1.89 g vs. 1.42 g per tablespoon) and slightly less saturated fat (1.62 g vs. 1.86 g). In practical terms, these differences are too small to affect your health. If you swapped one for the other in every recipe, your overall fat intake would barely change.
Where Olive Oil Pulls Ahead: Antioxidants
Extra virgin olive oil contains a class of plant compounds called polyphenols that avocado oil largely lacks. The most studied of these is oleocanthal, which produces that peppery, slightly bitter sensation at the back of your throat when you taste high-quality olive oil. Oleocanthal works as a natural anti-inflammatory in the body, operating through a similar pathway as ibuprofen. Another compound, hydroxytyrosol, acts as a potent antioxidant that protects cells from oxidative damage.
These polyphenols are a big part of why extra virgin olive oil is a cornerstone of the Mediterranean diet and why it has decades of clinical research behind it. Avocado oil does contain lutein, a carotenoid that supports eye health, but its overall antioxidant profile is less robust and far less studied. If your primary goal is maximizing protective plant compounds, extra virgin olive oil is the stronger choice.
Where Avocado Oil Pulls Ahead: High-Heat Cooking
Refined avocado oil has a smoke point between 480 and 520°F, making it one of the most heat-stable cooking oils available. That’s well above what you need for searing, stir-frying, or roasting at high temperatures. Refined olive oil tops out around 390 to 479°F, which is still high enough for most cooking but not ideal for very hot applications like wok cooking.
Extra virgin olive oil, the kind with the most health benefits, has a smoke point of roughly 320°F. That’s fine for sautéing, baking, and finishing dishes, but it will smoke and break down during high-heat searing. If you frequently cook at temperatures above 400°F, refined avocado oil holds up better.
Avocado oil also has a milder, more neutral flavor than extra virgin olive oil. That makes it more versatile in dishes where you don’t want a fruity or peppery oil taste, like in baked goods or Asian-inspired stir-fries.
Both Oils Help You Absorb More Nutrients
Fat-soluble vitamins and carotenoids from vegetables need dietary fat to be absorbed properly. A study published in The Journal of Nutrition found that adding avocado oil to a salad increased absorption of beta-carotene by over 15 times and lutein by about 5 times compared to eating the same salad without fat. Olive oil produces a similar effect. The researchers found that the lipid source didn’t matter: it was the presence of fat itself that drove the absorption boost. So drizzling either oil on a salad or roasted vegetables will help your body pull more nutrition from those foods.
The Avocado Oil Purity Problem
Here’s something that changes the practical comparison significantly. A UC Davis study, the first large-scale analysis of commercial avocado oil in the United States, found that 82 percent of samples tested were either rancid before their labeled expiration date or adulterated with cheaper oils like soybean or sunflower oil. Some products labeled as “extra virgin” or “pure” avocado oil contained mostly other fats entirely.
The olive oil industry has its own history of fraud, but regulatory oversight and testing standards for olive oil are far more established. The avocado oil market is newer and less regulated, which means you’re more likely to get a product that doesn’t match its label. If you buy avocado oil, look for brands that provide third-party testing or certifications. Without those, you may not be getting the oil you’re paying for.
Which One Should You Use
For everyday cooking at moderate temperatures, salad dressings, and drizzling over food, extra virgin olive oil gives you the best combination of healthy fats and protective antioxidants. It’s the most researched cooking oil in nutrition science, and its benefits are well established across large, long-term studies.
Avocado oil is a strong option when you need a neutral-flavored oil for high-heat cooking. Its fat profile is just as healthy as olive oil’s, and it handles temperatures that would degrade extra virgin olive oil. The main caveat is sourcing: make sure you’re buying from a reputable brand, since the majority of products on shelves may not contain what they claim.
Keeping both in your kitchen covers the widest range of cooking situations. Use extra virgin olive oil as your default for flavor and antioxidants, and reach for refined avocado oil when the heat goes up or the recipe calls for something neutral.
