When you heat olive oil, it gets more gunk in it — and the hotter you go, the more gunk forms. Some oils (like Armonia) get way gunkier than others (like Manzanilla).

Effect of Heating Temperature of High-Quality Arbequina, Picual, Manzanilla and Cornicabra Olive Oils on Changes in Nutritional Indices of Lipid, Tocopherol Content and Triacylglycerol Polymerization Process

Cross-Sectional Study

In Vitro

2023 May 22

The study heated different types of olive oil and found that hotter temperatures make them break down more, and some oils resist damage better than others — which matches the claim’s main idea, even if the exact numbers don’t perfectly line up.

Similar Assertions

Heating olive oil really hot makes it get gunkier — about 4.5 times more than at a lower heat — but even at the highest temperature, it doesn’t get gunky enough to be considered unsafe by food safety standards.

When you heat olive oil super hot, it starts forming gunk (polar compounds), but even at the highest temperature tested, it didn’t get bad enough to be considered unsafe for frying by food safety rules.

Prolonged heating of extra virgin olive oil generates significantly higher levels of polar compounds and oxidation byproducts than coconut oil and ghee.

When you heat olive oil really hot (200°C), it loses all its protective antioxidants and turns into more gunk than when heated at a lower temperature (170°C).
