Is Avocado Oil Superior to Olive Oil in Terms of Health? Let’s Explore What Research Reveals.

When it comes to choosing a healthy oil for your kitchen, avocado oil and olive oil are often at the top of the list. Both are rich in heart-healthy fats and offer a range of health benefits, making them popular choices for the health conscious.

But while both oils have a variety of culinary uses, there are some key differences. Whether you drizzle them over salad or use them in high-heat cooking like stir-fries, understanding the differences between these two popular oils can help you make more informed choices.

So when it comes to avocado oil vs. olive oil, which one is healthier? Read on to learn about the origins, nutritional profiles, health benefits, and culinary uses of avocado oil and olive oil to help you decide which one best suits your needs.

Origin and production

Although the origin of each oil is different, their production process is similar, especially for virgin (unrefined) oil.

Avocado oil production

Avocado oil comes from the flesh of ripe avocados. The fruit is pressed to remove the oil; once a paste of the meat has been made, it is mixed slowly to help release the oil. This process usually takes 40 to 60 minutes at about 110 to 120 degrees F. Although this is done at a higher temperature than olive oil extraction, it is still considered cold pressing.

Once the oil has been removed from the fruit, it can either be refined or left in its natural state. Unrefined or extra virgin avocado oil has a deep green color and a robust, buttery flavor. Oil extracted from low-quality fruits is often further processed to remove unwanted colors and odors. Refined avocado oil has a pale yellow color and a milder flavor profile.

Olive oil production

On the contrary olive oil comes from the flesh of olives. Like avocado oil, the fruit is pressed to remove the oil. Olive oil can be refined or unrefined. Extra virgin olive oil is the least processed type of olive oil and retains a strong, peppery flavor. It is also packed with beneficial compounds such as polyphenols.

Refined olive oils have a lighter flavor and color. They also have a higher smoke point, making them better for cooking at high heat. Olive oil must be packed in dark containers to prevent degradation by light.

Nutritional comparison

When it comes to the nutritional composition of avocado oil and olive oil, they share many similarities.

Avocado oil

Avocado oil is rich in monounsaturated fats, especially oleic acid. It is also rich in vitamin Econtaining an additional gram per tablespoon compared to olive oil. Although it contains slightly more calories and fat than olive oil, it is also slightly lower in saturated fat.

Olive oil

Olive oil is rich in monounsaturated fats and, like avocado oil, contains about 70% to 80% oleic acid. It is also an excellent source of antioxidants, such as polyphenols and vitamin E.

Health benefits

Avocado oil and olive oil share similar health benefits due to their high content of monounsaturated fats, antioxidants and vitamin E.

A study of over 93,000 people found that those who ate monounsaturated fats from plant foods such as olive oil and avocados had lower rates of death from cancer and heart disease.

Benefits of avocado oil

The monounsaturated fats like oleic acid found in avocado oil are linked to several heart health benefits, such as reducing LDL cholesterol levels.

In one small study with 13 people, participants ate a high-fat, high-calorie meal with either butter or avocado oil. After the meal, several blood markers were measured. They found that the people who ate the meal with avocado oil had significantly lower levels of triglycerides (fat found in the blood), total and LDL cholesterol, inflammatory molecules, and blood sugar compared to those who ate the meal that contained butter.

With its higher vitamin E content, avocado oil can also benefit skin health. A older study involving 13 people with chronic plaque psoriasis found that a cream containing avocado oil and vitamin B12 was effective for the long-term treatment of psoriasis. However, it is unclear whether the benefits were due to the avocado oil alone or to the combination of avocado oil and vitamin B12. More research is also needed to determine if eating avocado oil has the same skin benefits as using it topically.

Benefits of olive oil

A staple of the Mediterranean diet, olive oil is full of anti-inflammatory polyphenols, which can reduce the risk of certain chronic diseases such as heart disease and cancer. They may also protect against neurodegenerative disease and osteoporosis.

A systematic review and meta-analysis looking at the effect of olive oil consumption on chronic disease found the following:

• A 16% reduced risk of heart disease for every 25 grams of olive oil eaten daily.
• A 22% lower relative risk of type 2 diabetes for every 25 grams of olive oil eaten daily.
• An inverse relationship between olive oil consumption and death from any cause (in other words, eating olive oil was associated with a lower risk of death).

Research also suggest that consumption of olive oil may help improve brain function and protect against cognitive decline.

Are there any risks?

Overall, avocado oil and olive oil are considered safe oils to consume. However, there are some safety tips to keep in mind.

Health Considerations of Avocado Oil

While avocado oil is generally considered safe, those with an avocado allergy should avoid it.

In addition, a 2020 study found that many store-bought avocado oils had issues with quality and purity. Many of the oils tested were found to have oxidized (meaning they had begun to spoil), likely due to poor storage, the use of damaged avocados, or harsh processing methods.

However, extra virgin oils (which are usually more expensive) should meet higher quality standards compared to refined oils, so choosing extra virgin avocado oil is a good way to ensure you’re getting a quality product.

Olive oil health considerations

Like avocado oil, olive oil is also largely considered safe. However, it can degrade (especially extra virgin olive oil) if exposed to high temperatures or light for extended periods. To ensure you’re getting a high-quality olive oil, choose an oil that comes in a dark glass container, which can help protect against light degradation. Store olive oil in a cool, dark place to ensure it does not spoil prematurely.

Some olive oils on the market can be adulterated with cheaper oils such as sunflower or soybean oil. To ensure your olive oil is pure, look for Protected designation of origin (PDO) or Protected Geographical Identification (PGI) seal, which indicates that the oils have been produced according to high quality standards.

Taste and cooking properties

An important difference between avocado oil and olive oil is their smoke point. The smoke point is the temperature at which the oil begins to break down and produce by-products that can change the taste of the oil and can also negatively affects health.

Cooking with avocado oil

Avocado oil has a robust, buttery flavor, making it ideal for salad dressings or as a finishing oil. Its high smoke point (above 480 F) makes it an excellent option for grilling and frying.

Cooking with olive oil

Extra virgin olive oil has a fruity, peppery flavor that can enhance cold dishes such as salads and dips. Its lower smoke point (about 400 F) do it is less suitable for high heat cooking, but a good choice for lower heat cooking methods such as sautéing.

Is one oil healthier than the other?

So when it comes to the question of avocado oil vs. olive oil, remember that both offer heart-healthy fats and a host of other health benefits. Avocado oil is slightly higher in calories and vitamin E. It also has a higher smoke point, making it better for high-heat cooking. Its robust, buttery flavor also works well in dressings and as a finishing oil.

On the other hand, olive oil, especially extra virgin olive oil, is packed with anti-inflammatory polyphenols and is a staple of the Mediterranean diet. It is linked to a reduced risk of heart disease, type 2 diabetes and cognitive decline. It is best used in cold dishes or for low to medium heat cooking, as it has a lower smoke point than avocado oil.

For quality and health benefits, both oils are an excellent choice. However, avocado oil is a better choice for high-heat cooking, while olive oil is ideal for adding flavor and health benefits to cold dishes and lower-heat cooking.
