Does olive oil have PAHs?


Does olive oil have polycyclic aromatic hydrocarbons (PAHs)?

Dr. Deane

Many foods naturally contain small quantities of PAHs. It is not good to eat foods high in PAHs as some studies connect them with cancer. Olive oil, like all other vegetable cooking oils, has been found to contain minute amounts of up to 17 PAHs such as benzanthracene and chrysene. Unripe olives tended to have more than ripe olives. Burning any cooking oil can increase the amounts of PAHs. This is not considered a major risk source in the diet and the oil would have to be heated repeatedly and for extended periods to the smoking point. It is unlikely that in home use olive oil or other cooking oils would be a significant source of PAHs.
