Cooking with Extra Virgin Olive Oil Can Be Dangerous To Your Health

We have always been told that Olive Oil was the best and healthiest oil to use. After all, it’s high in monounsaturated fats and antioxidants that are able to lower “bad” cholesterol and raise “good” cholesterol levels. It also has the Omega oils that you need for a healthy nervous system and cardiovascular system. But did you know that cooking extra virgin olive oil at high heats can be dangerous?

Cooking with Extra Virgin Olive Oil Can Be Dangerous

Every oil or fat that you cook with has a smoking point. When oils reach temperatures over that smoking point it releases toxic smoke that also have carcinogenic (cancer causing) properties. This is because it causes it’s enzymes to be destroyed, proteins become carcinogenic, carbohydrates become caramelized and all of the vitamins and minerals lose their nutrients.

Safe Ways to Use Extra Virgin Olive Oil

Try using EVOO drizzled over vegetables for roasting or pan-frying. Blend it with your hummus or sauces for a smooth, delicious flavor with great health benefits!

If you do decide to cook with EVOO be sure to not cook over 320º. If you do, be sure to choose a lighter, more refined olive oil with a higher smoke point. That way you can still benefit from all of the healthy benefits it has.
