FaceTweet it!

A few years ago, I jumped on the olive oil bandwagon. I tossed all of my other cooking oils and was solely using olive oil for all of my cooking.  Big Mistake! While olive oil has many positive health benefits:

  • Protects against heart disease
  • Decreases bad cholesterol (LDL) while increasing good cholesterol (HDL)
  • Can possibly protect from colon, breast, ovarian and prostate cancers
  • High in antioxidants
  • Can improve insulin sensitivity in Diabetics
  • Anti-inflammatory effect in Asthmatics
  • Great for moisturizing skin

What I did not know was that to gain the positive health benefits, olive oil should be consumed:

  • Raw
  • Cooked at low-medium heat

In fact, cooking at high heat with olive oil can be extremely unhealthy for you. Cooking or frying with olive oil at high heat past it’s smoking point can create polycyclic aromatic hydrocarbons (PAHs).  PAHs are basically byproducts of burning oil.  At high concentrations PAHs are carcinogenic, mutagenic, and teratogenic. Below is a list of various oils that can be used at high eat or for frying.


Take home point: Olive oil has great health benefits, but should not be used with high heat cooking or frying since it can possibly be carcinogenic.

    cooking any oil at high heat is bad for you. They all release toxic aldehydes but a high polyphenol extra virgin olive oil releases less toxic aldehydes than all the others when heated to smoke point. You missed out the virtues of oleocanthal for brain health in your list above. Oleocanthal in a high polyphenol extra virgin olive oil is the healthiest polyphenol for your brain. Suggest you google it to see why.
