In recent years, avocado oil has become increasingly popular, occupying significant shelf space in grocery stores. While both avocado oil and olive oil are celebrated for their health benefits and culinary versatility, understanding their differences can help you make informed choices for your diet and cooking needs.
Origins and Types
The primary distinction between olive oil and avocado oil lies in their sources. Olive oil is extracted from pressed olives, a practice deeply rooted in Mediterranean tradition. Avocado oil, on the other hand, is derived from the flesh of the avocado, the green part of the fruit.
Olive oil comes in various types, each with distinct tastes and uses. Extra virgin olive oil (EVOO) is extracted from the first cold pressing of fresh olives, retaining the highest levels of nutrients, antioxidants, and flavor. Other types include pure or refined olive oil, which may contain a mixture of cold-pressed and refined oils.
Avocado oil also comes in two main varieties: virgin and refined. Virgin avocado oil is cold-pressed, preserving its natural color and flavor, while refined avocado oil is extracted using heat and sometimes chemical solvents, resulting in a less flavorful product.
Extraction Process
Avocado oil is made by grinding the flesh of the fruit into a paste, malaxing (kneading or rubbing) the paste, and then separating the oil from the solids. This process influences the oil's final composition and quality.

Nutritional Profiles
Both avocado oil and olive oil are considered "good fats," primarily composed of monounsaturated fatty acids that are beneficial for heart health. They also contain antioxidants and Vitamin E. A comparison of their nutritional content reveals key similarities and differences:
| Nutrient | Avocado Oil (1 tbsp) | Extra Virgin Olive Oil (1 tbsp) |
|---|---|---|
| Calories | 120 | 120 |
| Total Fat | 14g | 14g |
| Saturated Fat | ~2g | ~2g |
| Monounsaturated Fat | ~10g | ~10g |
| Polyunsaturated Fat | ~1-2g | ~1-2g |
| Vitamin E | 23% DV | 33% DV |
Both oils contain similar quantities of oleic acid, a healthy monounsaturated fat that can help reduce cholesterol. Avocado oil is higher in polyunsaturated fats, which are beneficial for essential fatty acid intake. Olive oil contains slightly more vitamin E.
Health Benefits
Heart Health
Both avocado oil and olive oil are rich in monounsaturated fats, particularly oleic acid, which may help lower LDL (bad) cholesterol levels and reduce the risk of cardiovascular disease. Research consistently finds that people who consume more monounsaturated fats have healthier metabolic and cardiovascular health profiles.
Antioxidant Properties
Olive oil is notably high in antioxidants such as vitamin E and polyphenols, which help combat oxidative stress and reduce inflammation in the body. Avocado oil also contains antioxidants, including lutein, which is great for eye health, although typically not as much vitamin E as olive oil.
Skin Health
Both avocado oil and olive oil benefit the skin due to their fatty acid profiles and vitamin E content. Applying avocado oil can help soothe dry, chapped, or damaged skin. Olive oil has been shown to prevent infections and help heal burns, cuts, and pressure wounds.

Nutrient Absorption
The high levels of monounsaturated fats in both oils may help the body absorb important nutrients, especially carotenoids, a type of antioxidant found in many colorful fruits and vegetables.
Digestive Health
Scientists have found that incorporating avocado oil and olive oil into your diet boosts digestive health, protecting and promoting a healthy gut. The flavonoids in olive oil are known to have antibacterial effects.
Potential Cancer Prevention
Olive oil, with its rich polyphenol content and anti-inflammatory properties, may offer protective effects against certain types of cancers. Avocado oil, like olive oil, contains compounds that may offer some health benefits.
Culinary Uses
Smoke Point
One of the biggest differences between avocado oil and olive oil is their respective smoke points. Avocado oil has a slightly higher smoke point at 480-520°F (250-271°C), while extra virgin olive oil smokes around 350°F (176°C), and pure olive oil smokes around 465°F (240°C). This makes avocado oil a better choice for high-heat cooking methods such as sautéing, grilling, searing, and baking.
Flavor
Avocado oil offers a mild, buttery flavor with a slightly grassy undertone, making it ideal for high-heat cooking and enhancing dressings. Olive oil varies in flavor, ranging from fruity and peppery in extra virgin olive oil to more neutral in refined oils. Olive oil is well-known for its smooth, versatile flavor profile.

Environmental Impact
Avocado oil production typically requires more resources, including water and land. Avocado farming can contribute to deforestation and water scarcity issues in certain regions. Olive trees are drought-resistant and can be grown in regions with less water. Sustainable olive farming practices are well-established, particularly in Mediterranean countries.
Concerns and Considerations
A recent study revealed that a significant percentage of avocado oils on grocery shelves were rancid or mixed with other oils. It’s crucial to look for the harvesting date and check if the oil is cut with any other vegetable oils.
Choosing the Right Oil
The decision between avocado oil and olive oil depends on your specific needs and preferences. Consider the following factors:
- Cooking Temperature: Avocado oil is better for high-heat cooking due to its higher smoke point.
- Flavor Preference: Olive oil offers a distinct flavor that complements many dishes, while avocado oil has a milder taste.
- Health Goals: Both oils offer similar health benefits, but olive oil has more extensive research supporting its benefits.
- Budget: Avocado oil is generally more expensive due to its complex extraction process.
- Environmental Concerns: Consider the environmental impact of each oil's production.
