Don’t Let Your Healthiest Cooking Oils Go Up In Smoke
Don’t Let Your Healthiest Cooking Oils Go Up In Smoke

Olive, canola, peanut, sesame, grapeseed . . . these five heart-smart plant oils have one terrific thing in common: They’re rich in monounsaturated and/or polyunsaturated fats, which have cholesterol-lowering benefits. But overheat them and those healthy perks may go up in smoke. Cooking at high enough temperatures to set off smoke means the oil’s breaking down, losing nutrients, and releasing potentially carcinogenic free radicals. And when oil hits its “smoking point,” food cooked in it tastes off. But that doesn’t mean you shouldn’t cook with these healthful oils. Just pick and choose what you use. Here’s how.

Extra-virgin olive: It’s so heat-sensitive that chefs usually recommend not cooking with it -- it’s too delicate and too expensive. Instead, cook with pure or virgin olive oil, which can take much higher heat. Use them to quickly saute vegetables in a hot pan or slowly roast them in the oven -- just spritz lightly with olive oil, and then roast at 325–350 degrees Fahrenheit for an hour or so, till fork-tender.

Canola: This is a superb cooking oil. It has the least saturated fat of any vegetable oil (about half that of olive and peanut oils); it’s virtually tasteless, so you can use it in anything; and its high smoking point (400 degrees Fahrenheit or more) makes it perfect for hot cooking, like stir-fries and sautes.

Peanut: It’s also known for a high smoking point (around 440 degrees Fahrenheit). And if you choose refined peanut oil, it too is nearly tasteless. On the other hand, if you want the yummy, peanuty flavor that makes Southeast Asian dishes so delicious, cook with refined oil, but add a few drops of roasted peanut oil just before serving.

Sesame: Refined light sesame oil has a high smoking point (about 450 degrees Fahrenheit), which makes it terrific for stir-fries, though it doesn’t add much flavor. For that, choose dark sesame oil but -- because its smoking point is a fairly low 350 degrees Fahrenheit -- reserve it for drizzling on Asian noodle dishes or miso soup.

Grapeseed: Although a tad pricier than most grocery-store plant oils, grapeseed oil’s neutral flavor won’t overwhelm even the most delicate fish or vegetables. Yet its relatively high smoking point (about 420 degrees Fahrenheit) means it’s fine for brushing on fish or vegetables before grilling. Grapeseed oil is also low in saturated fat and high in vitamin E.  

The biggest benefit of keeping your cuisine well-oiled with these healthier options? Eating only healthful fat can make your RealAge 3.4 years younger.

Vegetarian times had an article about "CANOLA OIL" back in the "70's" telling people to not use the crap. It's amazing to me how information is suppressed from the people. LET THE TRUTH BEKNOWN.

I read that most canola oil is GMO, so I don't plan on using it unless it is organic. I think I will use coconut oil in place of some of the butter in my oatmeal raisin cookies.

Denauturing oils with too much heat (especially natural ones) will do just the opposite to your body. Well stated1

Posted by: Kitchen Pans | May 13, 2009 at 10:29 PM

coconut oil is the most stable oil for cooking with because it is made up of long chain fatty acids which do not break down or oxidize with heat.It basically does not hydrogenate like most oils.The fact that it is saturated helps in this regard as well.It does not make you fat,it makes you lean.They found this out when they fed it to fatten cows and it did the opposite.The veggie oils used in takeaways get progressively more hydrogenated each time they are heated up and cooled down.Great for your arteries..In fact coconut oil has the longest shelf life of any oil and can stay there for up to a year and still be ok to eat!

dont believe everything you read. its a sort of paid for advertising a particular product. canola oil is the worst among the lot.

the best oil for any purpose is coconut oil. happy and healthy eating to all.

Hi

Great post; and as a rider I'd say, in addition to choosing the right oil try to use well seasoned cast iron cookware to cook with. Well cured cast iron skillets, dutch ovens and baking pans are almost completely non stick, which means you can cook with the absolute minumum use of oil.

All the best

Coconut Oil does help you lose weight. I lost 17 pounds in 5 weeks and I was ingesting 2 tablespoons per day. Also, I use it on my skin - my elbows had dry patches and now they are gone. Be patient and keep using it. It is the only thing I have put on my skin in the last 2 1/2 years. My skin is so soft.

Posted by: CJ | April 26, 2009 at 05:30 PM

I cook w/evoo all the time but I also use canola oil. This was helpful becuz now-I'll switch to regular olive oil.
Thanx RealAge! :)

Is there a fat or oil that can help restore collagen to the cells?

Can you eat coconut oil straight from the jar? Maybe a teaspoon a day?

ve just started using sunflower oil in cooking (i.e. sauteing) and also when I make popcorn. What are its benefits?

Posted by: shirley henderson | April 11, 2009 at 12:50 PM

What about walnut oil? I've been given a recipe for salad dressing and was wondering if it also is a good product.

Posted by: barbara  | April 11, 2009 at 08:18 AM

I am using extra-virgin olive on salads,I never used coconut,canola,sesame or peanut oils, i do not know how to deal with them .

Posted by: naela osman | April 10, 2009 at 02:35 PM

Coconut oil doesn't have a very strong smell - just a light coconutty scent, lighter than your normal coconut flake.

I'm currently using Flaxseed oil, but will switch to coconut at my next paycheck.

Posted by: Kuri | April 10, 2009 at 02:04 PM

If you're planning on getting pregnant/already pregnant/breastfeeding, then using the GOOD oils should be fine - coconut, olive.

Using Canola oil might actually do harm to the baby, considering how.. bad.. it is.

Posted by: Kuri | April 10, 2009 at 02:03 PM

Does food cooked in coconut oil smell very strongly of the oil? That's my concern, after eating food in Kerala, South India.

Posted by: Shiraz | April 10, 2009 at 01:43 PM

People in the Caribbean islands have been making and using coconut oil for cooking and moisturing the body for years. The key is moderation along with exercise and diet. And I don't mean some fad diet, and unrealistic exercise program. Again eating from all types of food groups and using different muscle groups on a daily basis. People in other cultures walk more, ride bikes, cut their grass, talk with their neighbors more, kids play soccer, basketball and cricket for FUN, dance, laugh, use their brain more(no picture on cashier registers) plant their own kitchen gardens etc. on a REGULAR basis.

I have been using avocado oil for everything cooked at high temp for about a year. It is a wonderful choice, extremely high smoke point and good nutrition. (I use an induction cook top which can superheat oils so fast it's difficult to keep them from reaching smoke point before I get the veggies in the pan.)

Posted by: Suzan | April 10, 2009 at 10:17 AM

Thank you sooo much for all the valuable info. you have been sending!

I buy Grapeseed oil for high temp. cooking. The butcher at New Seasons market once gave me a temp guide. I used Olive oil for salads and vegs. (after they are steamed)

I want to share this info with my TOPS group. I have been a KOPS for 27 yrs. My highest wt. was 150, I struggle to maintain 130-133.

Wow! This is shocking about oil - both the health benefits and the dangers of highly processed Canola. My spouse cooks w/ it and I tried to get him to change to grapeseed, but he sees no harm. I will have to show him this thread. Thank you all who posted health info.

Posted by: Priscilla | April 10, 2009 at 09:21 AM

Canola is not genetically modified. I'm a farmer and grow it but do not grow GMO crops. SOME varieties of canola are GMO and some are not, similar the the corn and soybeans grown in the States.

Posted by: Sharon | April 10, 2009 at 09:20 AM

Canola Oil is NOT toxic. These people are propagating a HOAX that has been going around the internet for years.
DO THE RESEARCH YOURSELF! DON'T LISTEN TO HOAXERS!!
Check out Snopes.com or any other VALID myth-debunking site.

Posted by: Riosmom | April 10, 2009 at 08:40 AM

I suspect, but don't know for sure, that oils that oxidize (go rancid) in our cabinets also oxidize in our bodies (hence we need to take anti-oxidents to stay healthy). However, saturated fats, such as butter & coconut oil, that don't go rancid on the counter top also don't oxidize in our bodies.

Posted by: Misty Dawn | April 10, 2009 at 08:33 AM

I buy my coconut oil from Wal-Mart. It is in the section with all the rest of the oils. When you compare prices, it is a lot cheaper by the ounce than any other oil on the shelf.

Posted by: Walter | April 10, 2009 at 08:31 AM

Virgin olive oil is heat sensitive? haha, you guys are fools. Spain has been using it for millenia to precisely cook it at high temperatures and you come now and say do not cook with it? Yet you say to use canola oil which is much better?
Realage, just like many other american lobby paid sites, are just spreading garbage on the net. Time to stop reading american crap and get real info from other countries.

Posted by: Don't Know | April 10, 2009 at 08:18 AM

I'm so glad to see other comments on the health benefits of coconut oil. Canola oil is NOT good for you. The saturated fat in coconut oil, especially extra virgin coconut oil, is very good for you. Saturated fats are not your enemy. Transfats and processed foods are your enemy!

Posted by: Jane Hill | April 10, 2009 at 07:53 AM

canola oil is safe and healthy. please check out this article, from a trusted and highly regarded medical source, the mayo clinic. (and no, i don't work for the mayo clinic!)

thanks i have been buying canola oil because i throught it was healther than vegetable
oils

Posted by: Delores | April 10, 2009 at 07:40 AM

Actually take the time to read what www.Snopes.com has to say about Canola oil. The facts stated above are mostly myth. He references Snopes but if you actually hit the link you will see that his statements are just part of an internet hoax letter circulating around Canola oil. Some of the statements are true. But, the key statements pertaining to the grossly unhealthy use of the oil are pure exaggeration. Don't believe everything you read! Do your own research if you want an unbiased answer.

Posted by: Mike Hill | April 10, 2009 at 07:33 AM

You can buy coconut oil online from Tropicaltraditions.com.
& everyone is right about canola being BAD for you,
"Canola is not the name of a natural plant but a made-up word, from the words "Canada" and "oil". Canola is a genetically engineered plant (GMO) developed in Canada from the Rapeseed Plant, which is part of the mustard family of plants.
Rapeseed oil is poisonous to living things and is an excellent insect repellent." Which is why it goes through a rigorous processing.

& as far as the 1st paragraph about chefs telling you NOT to cook with extra virgin olive oil...have they never seen Food Network??
ALL the chefs cook with it. Rachel Ray even got EVOO into the dictionary.

These people need to get their facts straight if they are going to try to give us advice on healthy foods.

And thanks to all of you who gave the correct info! Knowledge is power!

Posted by: Kat | April 10, 2009 at 07:29 AM

I got my coconut oil at the health food store. There was one for skin and a "virgin" to eat. The jar was pricey at $10. It is a solid which I heat to put in drinks, etc. Just started using since went on web and looked up benefits of the oil.

Posted by: Dee | April 10, 2009 at 07:27 AM

Canola oil is NOT a healthy oil !! The public, including myself, has been duped into thinking that this oil is a healthy alternative, and now it is found mixed in with spreadable butter, and everything else. It is derived from the rapeseed, which is toxic. There is NO Canola plant! There is Corn oil from Corn, Sunflower oil from sunflowers, etc. But Canola is derived from the rapeseed. Read the hotlink above on the truth about Canola oil! I will spend more for Safflower oil, Sunflower oil, or any other oil before I ingest Canola - an industrial lubricant! Just because the FDA approves something doesn't make it safe!

Posted by: susan miller | April 10, 2009 at 07:09 AM

You must refrigerate all oils except for coconut oil. Polyunsaturated and monounsatured fats start to break down with heat. They are not stable in warmer weather, so especially don't keep them on the counter next to your stove where you cook, or over a warm dishwasher.

The reason you don't need to refrigerate coconut oil is because it's stable with heat, which is why it's ideal to cook with. Unrefined coconut oil has a smoke point of 350 F.

We need some saturated fat in our diet to make cell membranes (the outer cover of the cell), and our bodies are just a bunch of cells. People who are not eating fast-foods or many animal products may benefit greatly from eating coconut oil to get their saturated fat requirement. And even those on a fast-food diet may benefit from coconut oil's nutritional qualities. Of course, remember the key to a healthy life is moderation.

I learned so much more form the comments than the article itself. Throwing the canola oil away and going back to the others!!! Thanks everyone!

Posted by: Cynthia | April 10, 2009 at 06:49 AM

where do I buy coconut oil? I don't recall seeing it in grocery stores.

CANOLA? give me a break! one of the worst oils .

When we lived in Hawaii, we use to eat the green coconut and it is wonderful, better than any pudding you will ever eat. I cannot say enough about the wonders of coconut and it's Health benefits.

I agree with the fact that Coconut oil is the best for cooking. I have used it for my skin, and being an Esthetician for years, I have found it to be the best moisturizer for the body and the best for cooking. I also take it internally.but not too much, as it can cause weight loss and I need to gain.I also use Organic Olive oil, and Sunflower oil . Royce is right on.

Posted by: Patricia | April 10, 2009 at 06:23 AM

Your article on oils has some errors. Canola oil is not a healthy oil. Vey highly refined and not at all natural. Coconut is best for heating and yes you will loose body fat.Olive oil for none heating. Stay away from soy oils or any soy not fermented.There is lots of research on this topic and should not be ignored. There is nothing wrong with butter or animal fat as long as it is fed a natural diet. Grass fed beef has same omega ratio as wild salmon. Saturated fat is not as bad as once claimed, grain and vegetable oils do more harm.

I have also read a lot about the benefits of coconut oil, and a friend tells me that she lost her baby weight with exercise, and religiously having two tablespoons of the oil every day.

Posted by: Mehvash Amin | April 10, 2009 at 12:34 AM

yes coconut oil is good for dry skin good to eat but want to know ifs its high in calories

Posted by: artimalhotra | April 09, 2009 at 10:26 PM

I mix 3/4 cup coconut oil and 1/4 cup olive oil. Use as a spread in place of butter much of the time, very good. I also use coconut oil to pop popcorn. Coconut oil can be used for many different things. There are many books out there for info on coconut oil or go to www.coconutresearchcenter.org or look in your health food stores for info. Many books are writen by Bruce Fife, C.N., N.D. VERY interesting and informative.

I have been using palm oil for many years and I find that they are as good unlike some other cooking oil made your whole kitchen sticky after cooking. So just imagine if your kitchen get sticky what will happen to you body I am still trying to get an answer to that. And I find that seseme oil is fine too.
