When you heat certain types of olive oil really hot, the healthy antioxidant called alpha-tocopherol disappears completely in some kinds, but not as much in others — Picual and Cornicabra oils hold up better.

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

This study heated different types of olive oil and found that some, like Picual and Cornicabra, kept more of their healthy antioxidants when heated, while others like Arbequina lost almost all — just like the claim says.

When you heat olive oil really hot (200°C), the good antioxidants called tocopherols disappear—some oils lose them completely, while others like Picual and Cornicabra keep a little bit left.

96%

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).

86%

When olive oil gets super hot, the main antioxidant (alpha-tocopherol) disappears completely, but other minor antioxidants (beta and gamma) stick around a bit longer — and some oils protect them better than others.

84%

Some types of olive oil — especially Cornicabra and Picual — hold up better when heated than others like Arbequina, meaning they break down less and make less gunk when frying.

82%

Some olive oils — like Picual and Cornicabra — hold up better when heated than others, like Arbequina and Manzanilla, because they lose fewer healthy compounds and form less gunk when cooked.
