« Back to Glossary The Best Cooking Oil is Extra Virgin Olive Oil says, scientistsAustralian scientists compared the effects of heating Extra virgin olive oil and other oils, including refined olive oil, grapeseed, canola, sunflower, coconut, avocado, peanut and rice bran. The scientists heated the oils to extremely high temperatures, much higher than normal cooking temperatures, and performed several tests to show if the oils were still stable at high temperature. Then they looked at the chemical and physical changes that occurred when oil is heated. They measured the release of toxic compounds called polar compounds. The found that refined oils such as grapeseed, sunflower, canola oils, produced the most polar compounds. When oil is heated, it tends to break down into toxic compounds known as polar compounds. These compounds have been linked to the development of neurodegenerative conditions such as Alzheimer’s, Parkinson’s, chronic heart diseases. Analysis of the results also showed that an oil’s smoke point doesn’t predict its performance when heated. What it found instead was that when the smoke point is combined with the total level of unsaturated fats, that oxidative stability and UV coefficients are more accurate predictors. The study also discredited the notion that the use of canola oil is beneficial for health.
