Warning Olive Oil Good for Health but Not for Cooking

I am an LPN Nurse and recuperating from being very sick, this is how I ate myself back to health. This article continues telling the story of my research into a different kind of nutrition.

By Joan McDaniel          

Researchers concluded that olive oil is a major contributing factor to the health benefits of the Mediterranean diet. While olive oil can and should be a healthy part of your diet, what most people do not appreciate is that olive oil should not be used to cook with. It should be used cold or applied to a dish after it has been cooked.  Olive oil is primarily a monounsaturated fat which when heated can easily break-down and become perishable with oxidative damage and then forms free-radicals. As it turns out, extra-virgin olive oil contains chlorophyll that accelerated decomposition and makes the oil go rancid rather quickly. So if you plan on using a fat to cook with, your clear choice is coconut oil or butter. Coconut oil is rich in lauric acid which is a proven antiviral and immune system builder.

So in evaluating plant oils for cooking, it should be clear that oils that contain a high percentage of saturated fatty acids are more stable than those that contain a high percentage of polyunsaturated fatty acids. When exposed to heat and light during processing, storage, and use, oils that contain a high percentage of polyunsaturated fatty acids tend to contain more free radicals than oils that contain mainly saturated and/or monounsaturated fatty acids.

I have found that I can add olive oil after I have cooked the food.  I also found that if I mix olive oil with coconut oil, coconut oil stays liquid.  As long as you don’t heat the olive oil it is very good for you.

Your line of thought here is a little confusing. First, all unsaturated fats go rancid more quickly than saturated fats - that's just chemistry..free carbon chains eventually bond with something. But, that is a separate point from whether or not olive oil is good to cook with. The answer to rancidity is if you are going to use olive oil, buy from the most recent harvest (for better oils, usually printed on the side of the jar or can), use it within 3 months of opening and store it in a cool, dry, dark place in an airtight container. As for cooking with it, olive oil can partially hydrogenate after it hits its smoke point. But at ~400 degrees, you can do plenty of cooking well before the oil begins smoking. Just don't let the oil smoke and you maintain most of the beneficial properties. In certain parts of Italy and Greece, they cook with no other fat than olive oil and they do just fine!!

Olive oil is not recommended for saute or searing meat or fish. HIgh heat is needed to produce a proper sear (maillard reaction) and olive oil breaks down and smokes. Can produce a fire if not careful. Use canola oil or blended oil such as 10% blend olive/canola for sauteing. After food is cooked, finish with a sprinkle of good E.V.O.O. on plate.

canaan guy I'm glad you know about E.V.O.O. but I did research on canola oil and you would be surprised what I found. Use Coconut oil for sauteing. Here is the Link. Thanks for the comment Exactly, What is Canola Oil? http://coconutcreamcare.com/2012/09/17/exactly-what-is-canola-oil/

I know many people who swear by olive oil. That is fine, it is a very healthy oil. I find it best not to cook with it for I really enjoy Coconut oil. What ever you use do not use canola oil or hydrogenated oils such as vegetable oil. I also found that when I used olive oil after the food has been cooked and spread it on the food I can taste the oil. It seems to loose its taste for me once it has been heated. Thanks again for the comments.

Oh olive oil is not a saturated fat it is a monounsaturated fat. Saturated fats do not go rancid. Good advice J Bauer Thank you. I have another article that gives some information on E.V.O.O. Is your Extra Virgin Olive Oil Really Olive Oil? By Joan McDaniel http://coconutcreamcare.com/2012/08/06/is-your-extra-virgin-olive-oil-really-olive-oil/

Agree with you. For best high heat non refined oil, grapeseed I think has among the highest smoke point and I haved used it a number of times and I didnt think it imparted any flavor at all to my food. That said, it can be expensive. By the way, Joan, you should also caution people about any type of hydrogenated or refined coconut oil. The health benefits of coconut oil are lost when refined... the virgin, good stuff only!!

Joan..... Canola is corn oil.
Joan McDaniel November 27, 2012 at 03:19 AM
Well if it is Corn oil, then why not call it corn oil? Corn oil is polyunsaturated, oil. Canola is monounsaturated oil. During my research, I never found Canola oil ever identified as Corn oil. Give me a link to follow for this new information. Thank You

This article is spot on. Don't listen to the saturated fat myths!

I am glad I know this now. I used Olive Oil to do simple sautees. I like the added flavor I guess. Where do we find Coconut Oil for coooking What about peanut oil? For deep frying I would use the Crisco if I were to do it. I am not able to eat that fatty food as much now. Being old stinks !!!
Joan McDaniel November 27, 2012 at 03:04 PM
Crisco oil is hydrogenated vegetable oil or Trans Fat. It is not healthy. I have not looked into peanut oil for it is very expensive. You need your saturated fats. Without fats your body can not digest fat-soluble vitamins. Read the following article Eat a Good Salad Lately? http://coconutcreamcare.com/2012/07/20/eat-a-good-salad-lately/

I found coconut oil in a Asian Food store initially. I now order it on-line. I recently got it from Amazon at a great buy. You have to look around. The price charged varies a lot but you can find it 16oz. for no more than $7.50.
