When you heat olive oil, it makes more of two harmful chemicals — HNE and ONE — than the other oils tested, likely because it’s high in oleic acid.

Scientific Claim

Olive oil with abundant oleic acid produces greater amounts of 4-hydroxy-(E)-2-nonenal and 4-oxo-(E)-2-nonenal during thermal oxidation compared to other tested oils.

Original Statement

“Greater amounts of 4-hydroxy-(E)-2-nonenal (HNE) and 4-oxo-(E)-2-nonenal (ONE) were formed in the OVO with abundant oleic acid.”

Assessment Explanation

The abstract uses comparative language ('greater amounts') based on measured data, not causal or probabilistic claims. The phrasing matches the study’s descriptive design.

More Accurate Statement

“Olive oil with abundant oleic acid is associated with higher levels of 4-hydroxy-(E)-2-nonenal and 4-oxo-(E)-2-nonenal during thermal oxidation compared to soybean, peanut, and perilla oils.”

The study heated different oils and found that olive oil, which has lots of oleic acid, made more of two harmful chemicals (HNE and ONE) than the other oils, which is exactly what the claim says.

Similar Assertions

When you heat olive oil at high temperatures for a long time, it makes more of two harmful chemicals—HNE and ONE—than the other oils, because olive oil is mostly made of oleic acid.

88%

Olive oil, which has lots of oleic acid, makes more of certain toxic aldehydes like 4-HNE and 2-decenal when heated than oils like soybean or palm.

82%

Olive oil from Al-Jouf stays fresher longer than olive oil from Pakistan when left out at room temperature, based on how quickly it breaks down.

78%

When you cook olive oil too hot, it starts producing chemicals that smell rancid — like old nuts or grease — and these chemicals can be used to tell if the oil has been overheated.

76%

When olive oil gets really hot, one of its healthy compounds — hydroxytyrosol acetate — goes up, which might be a clue that the oil has been overheated.
