Did You Know that heating Olive Oil can make it lose its heart-healthy properties? Saturated Fats are often the best for cooking.
This is because of the molecular structure and oil composition. Saturated oils do not have double bonds so they are not sensitive heat light oxygen.
Unsaturated vegetable oils (vegetable oils) are extremely sensitive to heat and sunlight. These oils also have double bonds. Heating them can alter their molecular structure, and cause some to lose their health properties.
Olive oil containing monounsaturated fats is not heat-stable
Olive Oil is 70-80% monounsaturated oil in the form of oleic acids. Olive Oil has many health benefits including better insulin resistance, cancer fighting properties, and better health.
This monounsaturated fat gives Olive Oil its low smoking temperature. It is not recommended for temperatures exceeding 250°F (121degC span>).
Heat Damage Doesn't Cause Olive Oil to Contain Heart Healthy Polyphenols
Olive Oil is rich with antioxidant properties due to its phenolic substances. These include hydroxytyrosol and oleuropein. However, they lose their effectiveness when heated up.
Heating Olive Oil Helps Destroy Omega Fatty Acids
Dr. Mercola says that olive oil contains both Omega 3 Fatty Acids and Omega 6 Fatty Acids. Mercola states that omega-3 fats are "significantly structural components" of cell membranes throughout your body, and are especially rich in the retinas and brain. Sperm also contains docosahexaenoic, which is 36.4% of total oils. "
These fatty acid are sensitive and can be easily destroyed by heat.
Low Smokepoint = Avoiding Toxic Smoke
Toxic smoke occurs when oil is heated beyond it's smoking point. Olive Oil can cause smoke to form from cooking with it.
Many olive oil are fake
Some brands have substituted olive oils with cheaper oils such as soybean oil, canola oil and hazelnut oil.
In 2011, UC Davis did a study that found 73% of the top-selling imported Olive Oil brands didn't meet European Extra Virgin Olive Oil standards.
This could indicate that oils may be contaminated with vegetable oils such as corn, soy or cottonseed.
