On urban US supermarket shelves virtually every bottle of olive oil advertises itself as "virgin" or the "even better" varieties ("extra virgin", "first cold pressed" etc). I have read that many of these labels are hogwash, and that the contents of your typical supermarket "extra virgin olive oil" bottle pretty often include adulterants like palm, canola, or sunflower oil.

The North American Olive Oil Association maintains a list of genuine olive oils. They send people into grocery stores to randomly buy a bottle of one of the listed brands/varieties and test it in their lab. https://www.aboutoliveoil.org/64-certified-pure-and-authenti...

Is this one of those schisms like exists between USDA organic and California organic? Because your list doesn't include any olive oils I would actually eat, whereas they are all on this list: https://cooc.com/certified-oils/

A useful test for olive oil is its taste when swallowed. If it produces a hot sensation in the throat this is due apparently to oleocanthal, a major polyphenol in the oil. Oleocanthal has been cited in numerous publications as having anti-inflammatory and anti-cancer properties.

It's almost as if human nutrition and mortality are complex systems and a single foodstuff doesn't have any significant effect.

Not only that but surely nobody is surprised that the people who can afford the more expensive version of a product live longer.

Why have we not given up on this nonsense idea of miracle foods already?

Greek olive oil is considered the best in the world and doesn't suffer from Mafia infiltration which is a huge problem in Italy [1] [2] [3].

Nice. How would one go about finding such suggestion for consumption in Europe?

Earlier quoted context omitted.

I get California Olive Branch “100% California” EVOO because I heard it was genuine. Do you know if this is true, and if not, which brands are? I only add like 1tsp of oil to the pan when cooking so I can justify using the more expensive brands, though i don’t really taste a difference

If one trusts Consumer Reports they do a study every so often on best tasting (one of the cheaper Trader Joe's brand came out on top with EVOO in the middle tier off the top of my head), though if you use only small amounts for cooking one may not be able to tell a big difference. Also some studies showed people preferred rancid oil! so who knows, what we grow up with probably has a heavy influence on taste preferenc…

> Also some studies showed people preferred rancid oil!

I was once in a casual, blind taste test at an Anheuser-Busch facility where at least half of the dozen testers preferred the beer whose kegs had been sitting out in the hot sun for two weeks, instead of the kegs of the same vintage that had been sitting in the refrigerated warehouse during that time.

As they say, "there's no accounting for taste."

My understanding is that's mostly an issue with imported "blends" that claim olive oil from multiple sources. Single origin stuff is usually safer, and domestically produced Californian olive oil is usually what it says it is. You can also look for harvest dates and seals from the various olive councils for purity.

It's trickier than you let on.

At least for California, you have to look for the California Olive Oil Council seal if you want to be sure:

https://cooc.com/about-the-seal/

For example: there is a company called "California Olive Ranch." It used to have a popular olive oil sold in a lot of larger grocery stores that had the COOC seal. Then it started to source olives (oil?) from somewhere outside California and blend with the California olives[1]. That broke the rules of the COOC seal-- to have the word "California" on the label you can't blend with non-Californian olives. So the seal is no longer on that bottle, but the name "California Olive Ranch" is obviously on that label because it's the name of the company.

Thus, a shopper would be misled by your second sentence and buy an oil with olives and whatever else from imported non-Californian sources. That means the third sentence is also wrong-- looking for harvest dates and COOC seal isn't something that the shopper can do to double check their choice. Rather, that is the only thing they can do to be sure they're getting actual virgin olive oil of sufficient quality (the seal) that isn't rancid (the harvest date being within less than a year).

Edit: I don't have a link, but there was a recent COOC fiasco where a lot of the smaller farms got up in arms due to a proposed language change in the requirements for obtaining the seal. Don't remember the details, but it sure sounded like it would have made it easier for a member to blend with some amount of imported olives and still carry the seal.

Honestly, I think there's enough intrigue and drama in this topic of finding bona fide olive oil to start a substack subscription thingy if anyone is interested in that. :)

Yeah I would never buy anything electronic, or anything to consume or put on my body from amazon.
