Avocado oil has a high smoke point (about 270°C) and, like olive oil, contains many monounsaturated fatty acids. This makes it a good alternative for high-heat cooking.
In terms of flavor, avocado oil is more neutral than extra virgin olive oil. Olive oil offers a richer polyphenol spectrum and has been far more studied for health effects.
In price comparison, quality avocado oil is often more expensive than olive oil. When following a traditional Mediterranean diet, olive oil is the natural and historically proven choice.
