Quick Summary tl;dr
EVOO is a healthy because it’s rich in the monounsaturated fat, oleic acid, and contains antioxidant molecules called polyphenols.
Up to 80% of commercial EVOOs in the United States and United Kingdom are not actually extra virgin.
To pick out true EVOO you should (i) buy metal or dark glass bottles, (ii) buy oil that was "pressed," "crushed," or "harvested" within the last 18 months, and (iii) expect to pay at least $10 per bottle. The oil should also give you a peppery sting in the back of your throat when sipped.
What is Extra Virgin Olive Oil (EVOO)?
Extra virgin olive oil (EVOO) is among the world’s healthiest fat sources. It’s not only the richest source (~75%) of the super fatty acid, oleic acid, but it’s also overflowing with healthy antioxidants and polyphenols. What’s more, its intake is believed to help maintain a healthy weight ( 1), reduce oxidative stress ( 2) and inflammation ( 3), and protect against all manner of diseases, from heart disease ( 3, 4) to diabetes ( 5) to Alzheimer’s disease ( 6, 7, 8, 9, 10). Hippocrates, the father of modern medicine, even wrote that he was able to treat 60 health conditions using EVOO.
The label "extra virgin" is supposed to indicate that the olive oil is of the highest quality. It’s supposed to mean that the olives were picked and then immediately (within hours) cold-pressed in order to retain the antioxidants and polyphenols and in order to prevent the fermentation of the fruit and acidification of its oil. However, most EVOO is a lie!

The Lie About Extra Virgin Olive Oil
In a 2007 article for the New Yorker (and his subsequent book Extra Virginity: The Sublime and Scandalous World of Olive Oil), author Tom Mueller revealed that most EVOO is fake!
Countless other sources have since confirmed that, astonishingly, up to 80% of EVOO on the market isn’t extra virgin. Worse, some fake EVOO has been treated with chemicals, solvents, and heat to cover up the rancid taste, or even mixed with filler oils like canola oil.
That means, unless you go out of your way to avoid the big brands and actively hunt for the real stuff, you’ve probably been deceived. Since olive oil that is not extra virgin possesses inferior nutritional quality — it’s more likely to be oxidized and has fewer anti-inflammatory polyphenols — this fraud may be negatively impacting your health.
Looking at the Bottle: How To choose The Right Extra Virgin Olive Oil
The first step in discriminating true quality EVOO from fakes is looking at the bottle.
1. Only buy bottles that are dark glass or metal
This is because the oil gets oxidized by light and plastics can dissolve into the oil itself. So, if you see a bottle that is plastic, or even light glass, leave it and move on.
2. Look for "pressed," "crushed," or "harvest" date
Just because an EVOO is in the correct container, doesn’t mean it’s the real thing. The second step in finding true EVOO is to look for a "pressed," "crushed," or "harvest" date (don’t trust only a "best by" date). Good suppliers will tell you exactly when the olives were pressed to get the oil because they know that olive oil should be consumed within 18 months of being bottled.
3. Price matters
The third, and last, easy/necessary step is to look at the price. Real EVOO is expensive to produce; so, you should expect the good stuff to cost in the range of $10 to $40 per bottle. Sorry, but you get what you pay for when it comes to EVOO.
Beyond these three must-take steps, there are several other things to look for:
4. Bottles packaged with inert gas are better
Fourth, try to find a bottle that is packaged with nitrogen or some inert gas on top of the oil (this is quite rare, but a surefire way to know you have a great product). This packaging technique displaces the oxygen that leads to the gradual oxidization, and decrease in quality, of the oil as it sits in storage.
5. The more information the better
Fifth, if you can find a bottle that tells you the story of the oil (type of olive, country of origin, etc.) or instructions on how to do a sensory evaluation of olive oil, then you’ve probably found the brand you’re looking for.
While you don’t want a transparent bottle, you do want a transparent supplier who is confident enough to share the details about how their product was produced and how you can test it for yourself.
Evaluating the Taste & Oleocanthal
To really determine if an EVOO is truly extra virgin or a fake, you have to smell and taste it!
Start by dispensing about a tablespoon into a ceramic or plastic lid or cup. Swirl it around a bit to get the oil on the walls of the container and increase its surface area. Then cover the lid or cup with your hand and count to 20. This will trap the fragrances.
Take a whiff. It should smell fruity and strong. You can’t miss it (especially if you have a big Italian nose like me).
Now for the taste. Drink it all up! It should taste fruity, bitter, and pungent, not musty or fusty. Most telling of all, it should have a peppery kick! In fact, top-tier EVOO is sometimes referred to by experts as "two-cough" olive oil because it has such a strong peppery taste that it makes you cough, not once, but twice!
What’s With This Cough Thing?
It all comes down to a substance in EVOO called "oleocanthal." Oleocanthal is not only a super healthy anti-inflammatory polyphenol ( 11), it’s also an ideal litmus test for good quality oil.
Although there are about 36 different polyphenols in EVOO ( 12), oleocanthal is the only one that causes a peppery taste, and specifically in the oropharyngeal region (back of the throat). This is because the oropharyngeal region is enriched in TRPA1 ( 13) receptors, to which oleocanthal can bind, causing just enough irritation to make you taste pepper and, perhaps, cough.
(As cool health asides, oleocanthal may reduce the risk of certain cancers, inflammatory diseases, and brain diseases by reducing inflammation, stabilizing heat shock proteins, and preventing the buildup of amyloid and phospho-tau proteins.)
So, if you really want to know you’re getting super high-quality, super healthy, extra EVOO, search for that peppery kick in the back of your throat!
Reputable Seals of Approval
The above tips and tricks should enable you to find the real thing — true EVOO! But, if you still lack confidence, you can also look for the Extra Virgin Alliance (EVA) or California Olive Oil Council (COOC) seals of approval.
Either of these seals indicate that an EVOO has passed a series of chemical analyses and a professional sensory evaluation, i.e., it’s real. Having said that, not all real EVOOs have these seals. Furthermore, these seals don’t allow you to rank the best olive oils among each other. Yep, even among real EVOOs some are more "virgin" than others. So, if you really want the best of the best, you’re going to have to put the oil to the test.
Up to 80% of commercial EVOO is not actually extra virgin. Buy oil in metal or dark glass bottles that was pressed or harvested within the last 18 months. It should give you a peppery sting in the back of your throat when sipped.
