What the Mayo Clinic says about avocado oil
Mayo Clinic dietitians have consistently highlighted the health benefits of avocados and their oil, focusing on the type of fat they contain. According to registered dietitian Katherine Zeratsky, avocados are rich in beneficial monounsaturated and polyunsaturated fats, with only a small amount of the saturated fat that is more concerning for heart disease risk. Elizabeth J. Bailey, another Mayo Clinic registered dietitian, offers a simple tip for choosing healthy fats: "You can think good fat, think liquid at room temperature fat". She explicitly lists avocado oil alongside olive and canola oils as a healthy choice for cooking and salad dressings. Additionally, the Mayo Clinic includes avocados on its list of top foods to improve cholesterol, noting that the fiber and monounsaturated fatty acids can improve HDL (good) cholesterol levels and the quality of LDL (bad) cholesterol.
Nutritional profile: breaking down the fats
Avocado oil boasts a nutritional profile that is very similar to olive oil, with a healthy balance of fats. One tablespoon typically contains around 124 calories, 14 grams of total fat, with about 70% of that being monounsaturated fat. The primary monounsaturated fat is oleic acid, the same heart-healthy component found in olive oil.
Monounsaturated fats explained
Replacing saturated fats with monounsaturated and polyunsaturated fats is a key recommendation for heart health from organizations like the American Heart Association. The monounsaturated fats in avocado oil have been shown to help lower LDL cholesterol and blood pressure levels, reducing the risk of heart disease. Beyond heart health, the oil also contains potent antioxidants, such as vitamin E, lutein, and phytosterols, which protect cells from damage and offer anti-inflammatory benefits.
Avocado oil vs. olive oil: a comparison
While both avocado and olive oil are excellent additions to a heart-healthy diet, they have distinct characteristics that make them suitable for different culinary applications. The primary difference is their smoke point.
| Feature | Avocado Oil | Olive Oil (Extra Virgin) |
|---|---|---|
| Fatty Acid Profile | Primarily monounsaturated (high in oleic acid), similar to olive oil. | Primarily monounsaturated (high in oleic acid), similar to avocado oil. |
| Smoke Point | Very high, around 520°F (271°C). | Lower, typically around 375°F (190°C). |
| Flavor | Mild, neutral, or slightly buttery. | Strong, distinctive, and sometimes peppery. |
| Best For | High-heat cooking such as frying, roasting, and searing. | Low-to-medium heat cooking, dressings, and dips. |
Key health benefits of avocado oil
In addition to the heart health benefits highlighted by the Mayo Clinic and others, avocado oil offers several other advantages:
- Enhanced Nutrient Absorption: The healthy fats in avocado oil boost the absorption of fat-soluble vitamins (A, D, E, and K) and antioxidants like carotenoids from other foods. A study showed that adding avocado oil to salads significantly increases the uptake of carotenoids from the vegetables.
- Skin Health: Rich in vitamin E, avocado oil is a popular ingredient in skincare products. It can moisturize dry skin, protect against UV damage, and has been used to alleviate symptoms of inflammatory skin conditions.
- Antioxidant Properties: The antioxidants present in avocado oil help fight oxidative stress and inflammation in the body. This protective effect may reduce the risk of chronic diseases.
- Weight Management: While calorie-dense, the monounsaturated fats in avocado oil can increase satiety, helping to manage appetite and support weight management goals when used strategically.
Considerations when choosing avocado oil
Not all avocado oils are created equal, and quality is a crucial factor in maximizing health benefits. The processing method can significantly affect the oil's nutritional content:
- Choose Cold-Pressed: Opt for cold-pressed or extra virgin varieties, as these are minimally processed and retain the most nutrients. Refining processes can strip away some of the oil's antioxidants.
- Look for Quality Indicators: High-quality, unrefined avocado oil often has a vibrant green color. It should be packaged in a dark glass bottle to protect it from light, which can cause the oil to degrade prematurely.
- Avoid Contamination: Some lower-quality avocado oil bottles have been found to be mixed with cheaper oils. Look for reputable brands and certifications.
- Consume in Moderation: As with any fat, avocado oil is calorie-dense. It should be used in moderation as part of a balanced diet that includes a variety of nutrients.
Conclusion: an excellent addition to a healthy diet
As confirmed by Mayo Clinic dietitians and broader nutritional science, avocado oil is a healthy and versatile cooking oil. Its high content of beneficial monounsaturated fats, rich antioxidant profile, and impressively high smoke point make it an ideal choice for a range of cooking styles, from high-heat frying to delicate dressings. When selecting avocado oil, prioritizing quality—such as choosing a cold-pressed, extra virgin variety—ensures you get the maximum nutritional value. Used in moderation, avocado oil provides an excellent way to incorporate healthy fats into your diet and supports overall well-being. By swapping less-healthy fats with oils like avocado oil, you are taking a proactive step towards better heart health and nutrition.
