Avocado Oil

Avocado oil usually contains more unsaturated than saturated fat, but its composition varies with the fruit and processing. Replacing a saturated-fat-rich food with an unsaturated oil can fit dietary guidance; adding oil without replacing another energy source is a different question. Evidence specific to avocado oil in people remains sparse. A small meal study found favorable short-term biomarkers when avocado oil replaced butter, while a small trial in adults with metabolic syndrome did not show improved insulin resistance or oxidative stress.

These findings do not establish prevention of heart attacks, diabetes or other long-term illness. Whole-avocado studies also include the fruit’s fiber and cannot be assumed to show the same effects for its oil. Prolonged heating changes avocado oil, as it does other cooking oils, and the amount of deterioration depends on temperature, time and the particular oil. Product surveys raise concerns about authenticity and quality, but they do not show that every avocado oil is adulterated or that a particular meal contains harmful levels of degradation products.
