Defending Olive Oil’s Reputation

By Mark Sisson
202 Comments

Olive oil’s reputation has been besmirched. It isn’t the magic life elixir fueling the teeming hordes of Mediterranean-dieting, crusty bread-eating, moderate wine-drinking centenarians, but it doesn’t deserve to be tossed in the trash heap with soybean, grapeseed, corn, and canola oils. I sense that it’s fast becoming a “fallen fat” among our crowd and I think it’s a darn shame. Are a few extra grams of linoleic acid, one or two unfortunate incidents of adulterated oil, and gushing praise from vegans, vegetarians, and the American Heart Association alike enough to turn us against a staple, phenolic-rich food sporting several thousand years of storied history?

Allow me to explain myself. Early this week, I got an email from a reader: “I often roast my veggies with EVOO. Would butter be a better alternative, or are the fats in EVOO just as well?” This is an extremely common, totally innocent question. I get similar questions a few times each week. Moreover, I’ve noticed a general undercurrent across the paleosphere of folks avoiding olive oil altogether, either because it isn’t necessary for health, has too much linoleic acid, or it’s too prone to oxidative damage when exposed to the elements (heat, oxygen, light). I’d like to address each of these, particularly the oxidative stability. And I’ll answer whether I think we can cook with it or not.

Do we need it?

Now, you don’t need to eat olive oil to be healthy – agreed. I would enjoy life less without good extra virgin olive oil, but I could be healthy without it and I can see why people would find it unnecessary. Besides, good olive oil can be hard to find or expensive, while a slab of good grass-fed butter is almost always more affordable.

Is there too much omega-6?

Olive oil does have a fair amount of linoleic acid, with some varieties reaching concentrations of 20%. Using such a variety for the majority of your added cooking and salad fat – especially on a high-fat Primal Blueprint eating strategy – would mean eating excessive amounts of omega-6. Note, though, that some olive oil varieties are far lower in linoleic acid, and most extra virgin olive oil runs about 10%. Two tablespoons of the average stuff gives you about 2.8 grams of linoleic acid. That’s less omega-6 than most lard and poultry fat, if you’re counting, especially if you use it sparingly as a drizzler or in salads.

Isn’t olive oil too unstable for regular eating? What about the oxidation?!?

As for the oxidative potential of olive oil, that depends on a few things. Your olive oil is only as unstable as its environment. Heat, light, and exposure to oxygen all impact the oxidative stability of olive oil, as does the presence of antioxidants and phenolics. Of course, this is all works in a dose dependent manner; the more heat, light, and oxygen exposure, the greater the oxidative potential, while the more antioxidants and phenolics present, the lower the oxidative potential. Ultimately, it’s up to you to source good quality oil and store and handle it properly. If you buy your olive oil at Costco in two-gallon clear plastic jugs, don’t be surprised when it doesn’t hold up as well as the extra virgin deep green olive oil that leaves streaks of olive sediment behind and burns your throat going down. If you store your olive oil next to the stove, often forget to secure the cap, and expose it to plenty of kitchen lighting, it’s not going to last very long.

What about heating it? Should you ever cook with olive oil?

Surely heating such a fragile plant oil will render it inedible, toxic, and liable to result in oxidized serum lipids if eaten. Right? Not so fast. While subjecting extra virgin olive oil to high heat can alter the taste, it’s actually fairly resistant to oxidative damage from cooking. Let’s take a look at some studies to make sure:

In one study, the authors heated various oils to “deep-frying conditions” and checked oxidative markers every three hours. The olive oils made it 24-27 hours of constant high heating before reaching the maximum legal value of heat damage. Not bad, and it’s not like you’re going to use your olive oil to deep fry anyway.

Despite being heated at 180 degrees C (356 degrees F) for 36 hours, two varieties of extra virgin olive oil exhibited strong resistance to oxidative damage and retained most of their “minor [phenolic] compounds.”

But then there’s this study, in which subjects were given heated olive oil meals, heated safflower oil meals, unheated olive oil meals, and unheated safflower oil meals. Both of the heated oils and the unheated safflower oil resulted in elevated postprandial oxidative markers, while eating unheated olive oil resulted in none. Note, though, that the olive oil was probably refined or light (otherwise they would have called it “virgin” or “extra virgin”) and thus devoid of significant phenolics with antioxidant properties. Also, the oils were heated at 210 degrees C (410 degrees F) for eight hours, which seems excessive. The home cook sauteeing some shrimp and onions in white wine and EVOO is unlikely to hit 210 degrees C, let alone stay there for eight hours.

You’re probably aware of the oft-cited benefits of olive oil on blood lipids. Namely, that it raises HDL and lowers LDL. You’re probably rightfully skeptical of the relevance of these changes in numbers. I am too, so let’s not talk about those. But how do you feel about oxidized LDL? Many are beginning to suspect that a causal link between oxidized LDL and atherosclerosis exists, and I think everyone agrees that reducing the oxidative potential of our lipoproteins is a good thing. The story as commonly told is, roughly, that unsaturated fat-rich LDL are inherently unstable and prone to oxidative damage, so eating a lot of unsaturated fats will mean vulnerable LDL and eating lots of saturated fats will mean stable LDL. Since the primary fat in olive oil is the unsaturated monounsaturated oleic acid, the common idea is that eating too much olive oil will make LDL vulnerable to oxidation like the other unsaturated fats.

So, what does the research show?

Most studies show that extra virgin olive oil either reduces measurable oxidized LDL or reduces measurable markers for oxidized LDL in humans. Dietary extra virgin olive oil reduced the number of oxidized LDL and increased HDL in proportion to the phenolic content of the oil; the more phenolics, the greater the effect. Tested LDL was also more resistant to oxidation after being removed from subjects and exposed to oxidative stress. Similar effects were found in a more recent study, in which men were given either EVOO with high phenolic content or refined olive oil with zero phenolics present. Men consuming high phenolic EVOO had less oxidized LDL and more phenolics present in LDL, indicating that dietary phenolics reach serum LDL and exert antioxidant effects in vivo.

A possible mechanism behind reduced oxidized LDL looks like an increase in oxidized LDL antibodies. In one randomized clinical trial, healthy men were given 25 mL of olive oil of varying phenolic content per day; a greater capacity for antibody production corresponded with higher phenolic intakes.

The proof, as they say, is in the pudding. Most evidence points to extra virgin olive oil being a highly nutritious, healthy addition to a diet. And for all the hand wringing about extra virgin olive oil being way too unstable to have around on a regular basis, let alone actually willingly ingest, it even appears to be protective against LDL oxidation when consumed in the pure, extra virgin, high phenolic, room temperature state (and even reasonably heated it doesn’t seem too shabby, either). From what I can tell, it does the exact opposite of what some people worry it will do to their blood lipids. For that reason, I think olive oil deserves another look. A fresh start, perhaps?

Let’s put it to rest – olive oil, especially good quality virgin olive oil with all the phenolics intact, is decently resistant to heat-incurred oxidative damage and a great addition to your diet. And if you’re worried about exposure damage, adding a bit of vitamin E to olive oilΒ seems to reduce oxidation. (Furthermore, rats who ate the vitamin E-dosed oil exhibited fewer signs of oxidative stress in vivo than the rats who ate the unenriched olive oil, so it’s not just cosmetic; it actually has an impact on how the food is processed in the body.) Keep your intake moderate, don’t use it as a frying staple, choose the good stuff, and try to use it mostly at room temperature. I find that the culinary benefits of extra virgin olive oil (the taste, the pepperiness, the subtle depth) and the nutritional benefits (the phenolics, primarily) become heightened when added at room temperature (or at the most gently warmed) to dishes. I love butter and ghee and coconut oil as much as anyone, but the undercurrent of fear surrounding the exposure of olive oil to slightly elevated temperatures and to oxygen is unfounded and, in my opinion, misguided.

The bottom line? If you’re making a tomato-and-meat-based sauce to go over spaghetti squash and you want the traditional Italian flavor, don’t worry about a bit of extra virgin olive oil going rancid due to some heat exposure. Give it some EVOO love. You and it will survive the journey intact.

Agreed. I render my own lard and tallow now (Mark, what have you done to me?!) and use this for most things I cook as well as occasional butter, but almost every salad or meat sauce I make gets a couple of swirls. So do my loaded omelets along with some herbs.

Nothing can replace that flavor, and honestly unless you know that you’re sensitive to EVOO, there’s no sensible reason to kick it aside.

Mary Enig in “Eat fat loose fat” claims that excessive monounsaturated oil can lead to fat gain.

Stephan at whole health food source claims that there is no studies showing any benefit of anti-oxidants.

Olive oil seems ok, however I am suspicious of it and have some around though whenever I can I will substitute butter or coconut oil.

Dr. Bernstein did a study on several of his patients (who had achieved weight stability on his low-carb diet), asking them to consume about 3 oz of EVOO daily in addition to their normal eating plan.

After 6 months, the average weight gain among those who consumed the extra 3 oz of EVOO (an extra 900 CALORIES!) daily was……..

ZERO.

Were there other effects noted from the test group? It’d be interesting to hear…

Howard

I did not see mention of any other effects from this study. Just the complete lack of weight gain that would have been expected from adding 900 calories per day. The “grams of fat” crowd insist that this would result in about 2 lbs/wk weight gain.

Fortunately, real science remains true whether or not you believe in it.

That’s interesting. Just another thing that goes to show calories don’t matter. I’ll have to see if Dr. Enig has a reference for weight gain on monounsaturated fat. Do you happen to have a link to the Dr. Bernstein study? 3oz. of olive oil is more like 750 cal. Even if you assume all 3oz are pure fat, that ends up being 85g. Which is 9*85 = 760 calories. Mary enig was talking more about nuts though. I do see many people claiming that too many nuts on a primal/paleo diet can stall weight loss.

Hi Michal,

recently, Stephan changed his position on antioxidants. He claims, however, that they are in fact oxidants, but act via hormesis.
See his polyphenol series at

And Dr. Harris brings the whole thing to a broader perspective in this important post.

I’ve always used EVOO for sauteeing my spinach and brocolli rabe and if I want some potatoes (sweet or white) I use it for coating them for roasting. I had always thought as long as you didn’t heat it to the smoking point it wouldn’t be a problem.

I have been trying to find answers for familial hypercholesterolemia and have landed on the same idea that you shared in the article: “Many are beginning to suspect that a causal link between oxidized LDL and atherosclerosis exists.” To the best of my reading, it is not saturated fat in the diet, neither is it the actual cholesterol lipid numbers. It is what happens to the cholesterol while in the blood that is most important. Is it oxidizing? How does one protect it from doing so? Anybody else have thoughts on this? I know it is a bit off tangent… Read more »

It is my understanding that blood cholesterol numbers do not matter so much as the oxidation of LDL. Robb Wolf states that some cultures have high levels of blood cholesterol but do not have heart disease and vice versa. The oxidation occurs from stress and excessive carb intake

I’m just starting to read what Cordain says (apparently he has been more concerned about saturated fat than most Paleo-types). I think it goes like this: Sat fat does/will lead to thickening of the artery (atherosclerosis), but it is only via inflammation (i.e. sugars and grains) that causes the rupturing of the atherosclerotic cap) which is what causes heart disease)??

An area that is starting to be investigated is the oxidation of lipids and effect on our body. Unfortunately, the media or other ‘celebrity’ experts do not report that all lipids can be oxidized at different levels. With olive oil, international regulations stipulate allowable levels for extra virgin and therefore any producer selling it has to have an oil analyzed for levels of peroxides … primarily the outcome of oxidation during extraction depending on the quality of the machinery, miller expertise, etc. There can be huge differences in oxidation between different ‘EVOOs’.

It’s probably better to eat bacon that’s nitrate free. Also, though it’s hard to find, fresh side pork (uncured bacon) is great!

I love olive oil and don’t think I eat too much of it. I also use it in the shower to moisturize (rub a little bit onto your legs then rinse). That is one thing that the linoleic acid is great for!

It’s kind of like that old saying , not black and white, but shades of grey. It’s in the quality of the meat. “Regular” hamburger meat is grain fed and loaded up with hormones and processed. If you buy locally grown and butchered grass-fed beef for your hamburger meat… it’s great for you. Same thing with the bacon. I get extra thick, uncured, nitrate-free stuff from my local market. If you poke around on here, there are a lot of bacon-lovers on MDA. Same thing with sausage, depends on quality. I have a hard time finding sausage near me that… Read more »

Kelly

Yep, it gets a sort of “stale” scent (most oils do, actually). It’s not a terribly unpleasant smell, and it can be hard to pick out unless you have something fresh to compare it to. Sort of like the smell a towel gets if used several times and left damp.

Honestly, I think the only reason I tell my cooks to NOT cook with EVOO is because of the cost. The flavor is what gets destroyed with heat, so it makes sense to use a lighter olive oil for the cooking. As for whether it is healthy or not for you – seriously folks… I am really through with the nitpicking I see with oils, etc. Olive oil has a RICH tradition of thousands of years.

I used EVOO to roast some potatoes at Christmas years ago and forgot all about the roasting tray (my bad!). Months later, I noticed it lurking at the top of the oven and looked at it.

The oil in the tray was still liquid and it smelled & tasted O.K. (rancid flaxseed oil tastes bitter). That suggests to me that the EVOO I use is pretty damned stable.

The “Solesta” EVOO from Aldi I use has a pufa content of only 6.6% and it also passes the “fridge test”.

Coconut oil is solid at my room temperature for a lot of the year.

One of the newest trends that really seems to be catching on in the Olive Oil industry are single-varietal olive oils (generally from a supplier or a specialty Olive Oil Store) that feature higher polyphenol counts. The stores will highlight the varietals of oils that feature more polyphenols than others – specifically for health reasons. Some do like (and prefer) the more peppery taste that often can be associated with higher polyphenol count Olive Oils.

Anyone have thoughts about whether it is ever appropriate to use more refined types of olive oil? Even in the Primal Cookbook, Mark recommends sometimes choosing a refined olive oil over extra-virgin because of taste reasons – e.g. to make mayonnaise. I assume that refined olive oil is somewhat better in its lipid profile than typically used canola and vegetable oil. I also use refined olive oil for cooking for the oxidation reasons that are outlined in this post. I basically only use EVOO when I intend to consume it raw, basically in dressings. Can anyone enlighten me here? Do… Read more »

Buyer beware, though. Did you know that there is more Italian EVOO sold than is produced in Italy? Sure some is real but the fake or adulterated stuff doesn’t say it on the label.

I buy Greek stuff from my local Italian deli. (Does that make it a Greek deli too?)

I’ve been using evoo and the lighter versions for years now, no more canola and vegetable oils. I also use real butter and even some lard. The nly thing making me use less oils and fats is it seems in meals I use more oil in the more oily and acne prone I am. When I cut back on the oil I ingest the less oily my skin and scalp. Of course when I am n drying conditions it helps to have the abundance of oil naturally in my skin, but does get annoying.

I think the key to buying good quality EVOO is to source it locally. I purchase a small bottle from the Farmer’s Market on a regular basis but the olives are pressed 10 kilometres from my home. The oil is cloudy, peppery and has the burn on the throat that Mark was talking about. I mainly use it on salads but it is stable enough to cook with if I am running short on butter/coconut oil.

Strongly agree with poster above re “buyer beware.” It infuriates me that people have to spend good money on pricey “olive” oils at the supermarket that most likely are adulterated or refined. Given the inflammatory conditions that could be caused by high omega-6 vegetable oils, it’s no joke if you don’t get the good stuff. I suggest going out of your way to find a small producer (lots of them in CA that sell online) or maybe a trustworthy source for Italian or Greek oil. I buy olive oil from a family company in CA and it tastes wonderful and… Read more »

I read/heard somewhere awhile ago that Spanish olive oils were just as good as the Italian and less expensive.

My landlady owns the olive grove just over the fence line; she gave me five & a half litres of unfiltered oil: as for better from one country or another: piffle! The entire process must be taken into account, along with the soil & the season. Since I can see the trees through my back door, why bother with exported stuff? Much of what I eat is gathered & processed by me, or is a local product: eggs, stone fruit, apples blackberries, rose hips, grapes,, meat, vegetables; all within an hour’s walking distance, plus the wild greens & mushrooms.

Nice call Mark! I had read on PaNu about the supposed issues with olive oil and had experimented with not taking it – but found I naturally included it in my kick ass salads out of some almost primal intuition that I needed it!

Seems to me that we can lump Olive Oil in with nuts and fruits too….they are good, healthy and tasty, but lets not go over board on them!

That’s a great way of putting it, that makes the distinction so much easier. Especially for people like me who aren’t up-to-speed with the exact science and nutrition knowledge.

I read somewhere that EVOO had the closest profile of any oil to bone marrow in terms of its various types of fat. Not sure if it is true – can’t find the link. Apparently Jeanne Calment, the oldest person that ever lived smothered her food in Olive Oil. Mind you she also reputedly ate a kilo of chocolate a week and smoked a few cigarettes a day (hormesis anyone?)

I eat a BA salad every day. I make up my own dressing (1/3 olive oil, 2/3 cider vinegar plus spices) because i want to avoit the canola and soybean oils. I probably put about 90 mL on each salad, so that is 30 mL of olive oil. Is that too much olive oil to eat every day? I am fit and muscular (165 lb male), but can’t seem to loose the last bit of fat around the middle to look ripped.

I think you may have missed the point. The point of the article, as I see it, was that we shouldn’t worry about olive oil in the diet. It’s a damn healthy oil, as the data shows.

Worry not!

It’s not the “rules” that are changing – its the food. You can blame Monsanto for genetically engineering food into something that’s no longer good for us. Blame the plastic manufacturers for creating packing materials that contain numerous endocrine disruptors. Local doesn’t mean produce isn’t still covered in pesticides and the conventional crap looks “pretty” because it’s DESIGNED to look that way (yes, designed, like it came from an ad agency and not from the Earth). You can bitch and moan and groan about how “unfair” it is but it doesn’t change the fact that aluminum, plastics, pesticides, GMOs, sugars,… Read more »

Massively interesting write up here – I’ve certainly had my eyes opened a little. I always though Olive Oil was a flawless part of my diet, and that butter was a 100 times worse that olive oil. How wrong I was!

I honestly don’t see any problem with my olive oil consumtion. I use it daily in my salad dressings and what else is there to use?

I cook all my other food either in ghee, coconut oil, red palm oil or babassu oil and all of those are rock solid except when heated and thus unusable as salad dressing fat. Besides, i only get the best olive oil you can buy for money and therefore i tend to use it sparingly to make it last. A little goes a long way taste wise if it’s quality stuff.

Olive oil, specifically California olive oil, which is where 99% of domestic oil is grown and produced, is experiencing a movement very similar to California wines in the 1970s. The flavor profiles of excellent quality EVOOs are at least as multifaceted and distinct. Most Americans don’t know what good olive oil is. Once you try it there is no going back. Seek a California oil out on line from a California producer. California Olive Ranch is your best bet to find in the market place. The prices are not different from quality imported oils and you’ll cut your chance of… Read more »

Mark,

Isn’t the typical advice to use the light/refined version of olive oil for any cooking/heat, and to use the EVOO for non-heat applications like salads and toppings?

The thought being that EVOO is much less stable (lower smoke point), while the refined version has a higher smoke point. This has always been my understanding.

It’s much more than one or two unfortunate incidents, several recent studies have shown over 50% of oil imported from europe is rancid or has other things wrong with it. http://www.classicalvalues.com/archives/2011/02/extending_an_ol.html It is not even that they may be putting other things in it, sometimes it’s just shipping and sitting around in bright light.

Since those studies came out, i have switched to california olive oil to hopefully get fresher oil. But avoiding fraud is harder, there’s no real way to know without testing.

Spanish olive oil is so much better than Italian olive oil. Olives are picked in Italy earlier (green) than Spain because of elevation and climate. In Spain the olives are allowed to properly ripen so we get a much more smooth and peppery flavor than the “lawn mower tea” greenness of Italian olive oil.

I have nothing but love for olive oil and value its inclusion in my arsenal of fats! My primal pantry is also well stocked with tallow, coconut oil and grass-fed butter. I am rocking the Whole30 right now, so EVOO is a welcome ally as I fight butter withdrawls :). I second the praise for California oils. Here is my current favorite: http://www.chaffinfamilyorchards.com/about.php and I am excited to see US Wellness Meats now carries it too!

If anyone live in the Phoenix area or anywhere in Arizona for that matter, there is a lovely olive mill in Queen Creek, AZ. It is 40 minutes SSE of Phoenix and pressed in front of your eyes. Mmmm. Talk about fresh. Just FYI.

I really like my extra virgin olive oil..I would be “hard pressed” to give it up. however, I do not drink it…! it’s a terrific flavor enhancer to many things I enjoy.

I’m sorry, but after just recently studying in Tuscany for a semester, I’d sooner die clutching my green bottle of liquid fat magic than give it up. I went from fat-free lard-free synthetic snack neurotic to a fat-loving olive-lover in the span of a few months… I also have troubles digesting animal fats (butter included – lactose intolerance), so it’s really this or nothing. I believe buying oil is like wine as well: there are a few key points to notice (a dark thick glass bottle, checking the date to make sure it’s a recent product, EVOO for any straight… Read more »

Think about this – Olive Oil was used thousands of years ago in places with very hot, sunny climate – no refrigeration really & the way to cook was over FIRE…I think it’s safe to use in our a little less primitive kitchen πŸ˜‰

I eat approximately 2-5 oz of EVOO on most days of the week as I make my own salad dressings and always use it as the oil portion. I cook with coconut oil as I love the smell. I weigh the same today as I did 30 years ago. My bloodwork shows very low inflammation and excellent cholesterol numbers.
