Olive oil or coconut oil: Which is worthy of kitchen-staple status?

Coconut oil has developed a cultlike following in recent years, with proponents touting benefits ranging from body fat reduction to heart disease prevention. Sadly for devotees, the evidence to support these assertions remains rather sparse.

But there is plenty of research to suggest that other plant-based oils have advantages over their animal-derived counterparts, particularly when it comes to heart health. So which is best? While no specific type should be hyped as a panacea, one variety isn’t getting the press it deserves: olive oil.

The case for olive oil continues to grow

Olive oil is a staple fat in the Mediterranean diet, and its previously publicized benefits have largely relied on examining its use by European populations. This information is useful, but looking at olive oil within the context of American diets provides us with stronger data to guide dietary choices here at home.

A recent study published in the Journal of the American College of Cardiology looked at adults in the United States and found that replacing margarine, butter, or mayonnaise with olive oil was associated with reduced cardiovascular disease (CVD) risk. This is particularly notable because Americans tend to consume less olive oil than our European counterparts. In the US, high consumers averaged a little less than one tablespoon of olive oil a day, whereas daily intake in studies examining Mediterranean populations has been as high as three tablespoons.

After taking demographic and lifestyle factors into consideration, those consuming more than half a tablespoon per day had a reduced risk of developing CVD compared to those using olive oil infrequently (less than once per month). Consuming more olive oil was also associated with a decreased likelihood of dying from CVD. Even slight increases in olive oil consumption, like replacing roughly a teaspoon of margarine or butter each day with a similar amount of olive oil, had advantages.

Olive oil was also correlated with a reduction in inflammatory compounds that may contribute to the progression of CVD. Olives contain plant chemicals called polyphenols that may help reduce inflammation. Using virgin olive oil, which is extracted through mechanical rather than chemical means, is thought to offer higher levels of protective plant compounds than refined olive oils. Extra virgin olive oil (EVOO) is a product of the preferred, mechanical processing.

Though we need more research, these polyphenols may also extend benefits to other areas of the body, like the brain. For instance, along with other healthy diet habits like eating leafy greens, primarily using olive oil when cooking has been associated with combating the decline in brain function that happens as we age.

How does coconut oil compare?

Proponents of coconut oil cite the medium-chain fatty acids it contains as a benefit because of the unique way these fats are digested. It’s claimed these fats offer advantages related to weight loss and cholesterol, though these assertions remain controversial. Regardless, lauric acid, the primary fat found in coconut oil, is thought to behave differently from other medium-chain fats, and may not deliver as promised.

In a recently published study in the journal Circulation, which compiled data from a variety of trials, coconut oil did not show benefits related to waist circumference or body fat compared to other plant-based fats. Coconut oil, a tropical plant oil, also did not fare as well as nontropical plant oils, like olive oil, with respect to reducing other cardiac risk factors. In fact, coconut oil increased low-density lipoprotein (LDL) cholesterol, the kind associated with an increased risk of heart disease.

Coconut has been an important fat in a variety of traditional diets in Asia, and is touted to impart health benefits within these communities, including fewer cardiac complications and premature deaths. However, these diets often feature minimally processed coconut products, like coconut flesh, which are also higher in nutrients like fiber. Lifestyle habits in these Asian communities also typically include eating more fruits, vegetables, and fish than in many American diets.

That said, extra virgin coconut oil, which can be purchased in the United States, is arguably less processed, and often refined in a manner similar to EVOO. A recent trial published in BMJ Open looking at extra virgin coconut oil did not show an increase in LDL cholesterol when compared to EVOO during a four-week period. (Both oils performed better than butter.) Unfortunately, there are not enough human studies involving extra virgin coconut oil to support its use as a primary fat in our diets. Nor do we have information about its long-term effects here in the US.

And the winner is… olive oil

The benefits of using nontropical plant-based oils remain very promising, making olive oil a natural choice in the kitchen. Try oil and vinegar on a fresh summer salad, or in place of mayo in potato or tuna salad. Consider a drizzle of olive oil instead of a pat of butter or margarine when cooking vegetables. And keep coconut fat to occasional use, say, to enhance the flavor of a vegetable curry, or as a substitute for butter in baked desserts.

    This comparison between coconut oil and olive oil is like asking which is better: apples or oranges? Anyone who knows anything about fatty acid profiles will know that coconut oil and olive oil have very different fatty acid profiles. So, this is not a useful comparison: coconut oil and olive oil are both healthy oils, just as apples and oranges are both healthy.

    Complete double blind test is required with virgin covonut oil vs olive oil done at least a year including the chemical changes at high heat of frying. Memdn

    is olive oil safe when used for frying and cooking?

    • Neil Hogan

      There are a lot of scientific studies out there now that show that not only is EVOO safe for cooking, it also retains much of the polyphenol content. Studies have also found that cooking a basic tomato sauce with EVOO helps the bioavailability of the antioxidants in the tomatoes.

  5. Dr. Sylvain Ndebi

    Tropical diet, like the Asian diet mentioned, ALWAYS includes fish and, even more so, vegetables and FRUITS (that appear seasonally, abundantly, and nonstop). The typical North American diet is simply loaded with overtakes/overloads of ‘bad’ foods (e.g. packaged processed foods, mega-starchy foods like pizza, fried and greasy meats, etc.) and ‘regrettable’ eating habits (over-snacking, random fast-food meals, artificial sugars, overeating corn syrup, etc.). Seems that switching to anyone of these oils is better overall, and overlooking ‘suspicious’ ours-theirs terms like Mediterranean vs Tropical would help readers better.

    I love how you mention “coconut oil has developed a cultlike following during recent years”
    which is true,
    Makes me smile
    Thanks for your informative and knowledgeable News letter,
    Keep it up

  7. padmini chandran

    in asia the oil is always heated to saute the vegetables or curry.
    it is coconut oil that does not become toxic when heated.
    olive oil we can use in salads or when used without heating..



  8. Boon Ywe

    I believe macadamia oil is the winner in term of boiling temperature and Omega 3:6 ratio too.

  9. Lanier Dodson

    The question is not whether olive or coconut oil is better for you than butter, margerine, etc. My question is whether either is better than no added oil in the diet? That is the way I eat.

  10. Janaki Srinath

    maam, whiile olive oil has a near ideal profile of fatty acids required for us, focus should also be on mustard, sesame, soya bean, ground nut oils for their stability to with stand higher temperatures during cooking process.

  11. Jaap Willem

    The article mentions olive oil versus coconut oil for digestion but the advocates that got me buying the stuff convinced me with the argument that it deals better with heat so I fry my steak in it.

    I think their argument is that olive oile under heat undergoes sometype of malign chemical reaction and the coconut oil does not.

    I wonder if there is any truth to this line of thinking.


    There has been some opinion expressed that coconut and medium-chain triglyceride oil may delay the onset and progression of Alzheimer’s disease, Parkinson’s disease, ALS and other conditions.

    Do you have any comment? Thank you.

  13. Stephen Boyd

    Although I have always had my doubts about coconut oil, I do find it a bit frustrating that after all this time we still don’t seem to have big enough, long enough, well-designed studies to guide up. “Four-week study,” really?

    it would be useful to compare other oils such as Canola .

  16. Joseph Sebastine Poothullil John

    Dear Ms. Emily,

    Your article is well written and very informative regarding certain aspects of choosing edible oil for use in kitchen.

    But I would like to say that the best food for any person is the food available locally and also the food his/her previous generations were consuming. Each one of us are genetically programmed to consume the food our ancestors were using. Therefore, it is inconclusive to say that one food is better than the other without considering the above fact.

    What about avocado oil

  18. Marlene Chaplin

    Always easy to understand, helpful commentary from this publication.

  19. Virginia Smith

    Olive oil has a flavor that I can’t tolerate. If I had to substitute butter, canola oil, or coconut oil with olive oil, I would lose weight very quickly because I would eat very little, and I’m already too thin, according to the BMI. And no, I have not said that previously.

    • Sierra

      That’s okay, Virginia! Nutrition isn’t quite as hard and fast as most people think. Finding a healthy way to eat that includes foods you enjoy is better for your mental health, which in turn could actually be better for your physical health.

  21. Michael Carl

    According to Dr Dean Ornish (and other plant based diet advocates) olive oil is a no-no for people with known cardiovascular health issues. Can you comment on this ?

  22. Charles

    And olive oil makes a great laxative !!


    Very interesting. with this information, I was more confirmed of the knowledge that I’ve known before that olive oil is the best.
    I know that olive oil is usually used in salad as a dressing, can we use this in the frying of fish or tofu?
    Thank you

  24. Trevor FitzJohn

    How does EVOO compare to solvent extracted seed oils such as Canola?

  25. Will

    DO an article on cooking with Olive Oil and other oils.

  26. Sarah Stromeyer

    Can you please speak to the use of coconut milk (reduced fat) in Asian and Indian cooking? I scrape off most of the fat even from the ‘reduced’ cans. This works well in recipes. Is this milk healthier than the cooking oil?
    Thank you.

    • Sierra

      Definitely- but keep in mind that the portion size of oil vs milk is drastically different which can skew the comparison. Tbl for tbl, though, coconut milk is better for you than coconut oil. I’m not sure how coconut milk compares to something like EVOO, though, and would be interested in what anyone else has to say.

  27. Suzanne Stevens

    I agree about the benefits of EVOlive oil, but if you want to fry eggs in it, it doesn’t react well to that high of heat!

  28. Janet

    If you heat EVOO, are the health benefits the same? Is there such a thing as heating EVOO to too high a temperature?

    When EVCO is heated, does it change? For instance we hear about the smoke point being lower for coconut oil. Is that true for EVCO?

  29. Arun s

    I have used limited amounts of coconut oil when I cook or even directly mixed in in my diet. Yet I believe that based on yours and other studies that Olive oil is more effective in preventing CVD and other related maladies. There is no denying that coconut oil adds a wonderful flavor to a lot of dishes when it’s used in the preparation off various Asian dishes. Some fried foods in coconut oil taste markedly better than otherwise. If you try it on French fries for example the difference is obvious. Now, granted that not everyone is going to agree, esp if they have limited or compromised taste buds/ lack of tolerance etc.
    Cheers! 👌

  30. Chris

    Thank you! I have been a little averse to coconut oil since the saturated fat is so high. Nice on the skin though. We do use it in place of shortening in baking.

    The newer craze I am finding is actually MCT (Medium-chain triglycerides) oil, which is apparently coconut oil (and/or palm oil) changed somehow at the molecular level. It is all the rage for Keto diet followers, or folks who generally try to keep their carbs at a very low level (like me for the last 25 years). I am skeptical of this oil too, but have not found any reliable sources to help me understand this better. I probably won’t buy it, especially since it is so expensive, but I would love to see what actual scientific investigation ends up with.

    In the meantime I will stick with my trusty olive oil. Thanks for the validations. I am never quite sure what is good!


    I’m glad EVOO was the winner. I have been using EVOO for the past ten years and never had a problem with my Cholesterol. I started using Organic Coconut Oil, and my LDL Cholesterol number increased significantly, so I stopped using the C Oil. I will never use Coconut Oil again. I get my fats from EVOO, Avocado, and nuts.

    Thank You.

  32. Roxanne Gordon

    I have started to sauté with coconut oil because olive oil has such a high flash temperature, smoking, browning, it requires added butter. You cannot sauté meats or vegetables with olive oil alone.

  33. Bea Reynolds

    Any studies on comparing olive oil and avocado oil – wonder they they stack up?

    • L. Dassanayake

      Some websites state that although olive oil is the best of oils, it is not a healthy oil. Further it is said that it is not a key ingredient of the meditaranian diet. My question is ,is coconut milk powder healthy? Doctors say it is better than dairy milk for people who have flem problems ?

  34. Perry Caminis

    If a mayonnaise is made from a tsp of mustard, 1 egg yolk, and 1 1/2 cups of EVOO, are the benefits very nearly the same as using EVOO alone?

  35. Ram Athreya

    Ms Emily Gelsomin
    Before coming to any conclusions about (Virgin) Coconut oil , please read 2 books by Dr Mary Newport , who successfully treated her (late) husband’s Alzheimer’s disease.
    1. The Complete book of Ketones
    2.The Coconut oil & Low-Carb Solution for Alzheiner’s , Parkinson’s and other diseases.

  36. Steven G Ruimuku

    What about olive oil and avocado oil(CPAO)?
    Despite the fact that we can trace olive oils before the birth of Jesus Christ while the entrance of CPAO ia a very recent product in the market ,may be less than 50 years, I feel the latter is gaining preferences. But why? I don’t know.
    Can smoking point be the “stand alone” reason behind it?

  37. Karen Schwager

    Have there been similar studies done on Avocado oil? If so, would you consider sharing the information and commenting on use of same.
    Thank you

  38. Heracles Brandao

    Well, already expected, but what the following researches couldn’t hide, was the difficulty in having data for people of same regions when comparing different LDL levels between them.
    Also, about the different temperatures each oil becomes saturated after cooking, as well as if the butter not exposed in high temperatures for example, could be às healthy as olive or coconut oils after cooked, when they become saturated.
    But that’s a beginning, It really looks like people is adhering to a lifestyle change more and more.
