Oil which has begun to smoke has broken down. The smoke itself is toxic and the oil is said to be unhealthy.

Not to mention that the flavor has entirely changed for the worse.

Of course you can cook with olive oil quickly over high heat without it smoking. But when/if it does, then it's bad for you.

The problem is associated with reheating of oils, something most of us don't do -- except in deep fryers. Research has shown the practice to cause the formation of HNE, a toxin associated with several diseases, in highly unsaturated vegetable oils.

Here's the conclusion from the University of Minnesota's press release: "HNE is a well known, highly toxic compound that is easily absorbed from the diet," said Csallany. "The toxicity arises because the compound is highly reactive with proteins, nucleic acids--DNA and RNA--and other biomolecules. HNE is formed from the oxidation of linoleic acid, and reports have related it to several diseases, including atherosclerosis, stroke, Parkinson's, Alzheimer's, Huntington's and liver diseases."

Ignore it if you wish, but don't discount the science just because you dislike the findings.

Here's another article of interest from the National Women's Health Resource Center:

Wow I guess this is a passionate topic for some. lol. Thanks everyone. I don't know why anyone would get the oil that hot to make it smoke. But glad I have a better understanding. I can now correct that person who passed it along to me. Thanks.

I have never heard of olive oil being toxic. I have lived in Greece and Italy and have been a professional Chef over 30 years.

I've alerted the university. They've agreed to call off the research project and have retracted their findings.

I think that's the point, along with not reusing it.

This is just way too funny. Wouldn't that be a great way for the world to work.
If you denied your own existence, you would cease to exist.

The oil is not too hot if your food is not burned.

What's your point? No one has suggested that you get rid of it. You're reading something into this thread and into the research that simply isn't there.
