The less Linoleic Acid in your oil the better[1]. This image[2] is a good reference. Also, and as opposed to common beliefs. You can cook on olive oil[3] [1] https://openheart.bmj.com/content/5/2/e000898 [2]. https://www.doctorkiltz.com/wp-content/uploads/2021/04/LA-in...

Wait, less... or more? :| https://www.hsph.harvard.edu/nutritionsource/2014/11/05/diet...

less[1]. this video[2] is not the best reference but a very good summary on the industrialized oils and they alternatives

"Instead of using butter, cream, lard, and other animal fat as the primary source of culinary fat, one should use liquid vegetable oils like soybean, corn, olive, and canola oils for cooking, on salad and at the table."

Uh...

Edit: reading this back, it sounds somewhat like an attempt to shill a product. So, disclaimer: I have absolutely no affiliation with Jeff or the Cultured Oils, I’m just fascinated by it.

Serial entrepreneur Jeff Nobbs recently launched a new product in the food oil space: Cultured Oil*

I came across his writings* on the perils of seed oils earlier this year and it radically changed the way I eat.

After becoming aware of the danger high linoleic acid diets pose, as well as the climate implications of other oils, Jeff’s Cultured Oil looks incredibly impressive, albeit I haven’t had the chance to try it yet as they don’t ship to New Zealand.

In summary, from their FAQ:

“Cultured Oil is cooking oil made by fermentation, resulting in high levels of healthy fats, a small environmental footprint, a clean taste, and a high smoke point!

Fermentation describes the process of microorganisms (or "cultures") consuming natural sugars and converting those sugars into entirely new foods. Just as there are sourdough and wine cultures, there are also oil cultures. An oil culture converts sugar into the healthy delicious fats that make up Cultured Oil.

Cultured Oil is primarily monounsaturated fat, the heart-healthy and heat-stable fat also found in olive and avocados.

In every serving of Cultured Oil (1 Tbsp - 14 grams), there are about 13 grams of monounsaturated fat, 0.5 grams of saturated fat, and 0.4 grams of polyunsaturated fat. Olive oils and avocado oils contain between 55-83% monounsaturated fat, and up to 21% polyunsaturated fat. Cultured Oil contains over 90% monounsaturated fat and less than 4% polyunsaturated fat

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. I can definitely taste the diff between supe…

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

Once you heat it, the differences become negligible to nonexistent. Good-quality oils are most important in raw uses, such as dips and salad dressings.

It's a hassle to maintain a "cooking olive oil" and a "raw olive oil", so the worst you're doing is wasting a tiny bit of money for the convenience of keeping around just one bottle.

As for the particular brand you mention... yes, it's very well reputed. Being produced in the US, there are fewer opportunities for fraud that occur when importing mass-produced oils. (Imported artisan oils are often extremely good, but pricey because of the overhead.)

You probably would notice the difference if you were to compare it to other brands -- especially when the bottle is newly opened. In cooking... eh, I just use a bottle of whatever's cheap.

It's cookable at lower temperatures but if you're going anywhere north of "5" on the stove chances are it's going to burn hard enough to stick to the pan

True, anything above 190 Cº (375 Fº) and it's going to start smoking

Italian mobs selling "virgin olive oil" likes that article. My main point is that I am not able to tell real virgin olive oil from scam one. From what I understand most of "virgin olive oil" on supermarket shelves is scam.

I tend to think that the California grown/produced olive oil is less likely to be adulterated vs OO from Spain and Italy.

When buying in the US, I assume that you mean.

Seeing a lot of comments about how supposedly a lot of EVOO sold on store shelves isn't actually pure olive oil, and I'm curious where this belief comes from. Any data or studies you can point me to? Here's an FDA report of 88 EVOO bottles purchased from supermarkets that were tested, three of which were identified as impure enough to possibly indicate they were adulterated: https://www.researchgate.net/publication/2…

It's not "adulteration" so much as fraud by mixing it with cheaper oils or labeling oil as "extra-virgin" when it's not.

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 preferences. You might want to try some white bread and maybe a little garlic mixed in your oil and use that as a dipping sauce to get a sense of the flavor (over just drinking it. :) ). UC Davis might have a California bent and be California ag sponsored but because it has an agricultural college there are plenty of studies originating there about olive oil. Just search UC Davis and olive oil.

I think that is the brand I picked up at Walmart one time. And I really did notice the difference -- it had a more buttery texture, and was delicious on my salad.
