Table "properties of vegetable oils". Rape oil (huile de colza / Rapsöl) should be included in the table. 83.253.72.105 (talk) 18:50, 27 August 2022 (UTC)

Virgin oil
I came here to find out what the difference is between virgin and non-virgin olive oil. And was disappointed that it's not explained. In the Extraction section we learn that olive oil is extracted by a mechanical process, and that the oil produced in this way is called "virgin". But we never learn what non-virgin oil is. Someone decided that the definition of "extra virgin" is important enough to go in the lead, so I would expect to find an explanation of non-virgin, virgin, and extra virgin fairly prominent in the article.

Olive oil and cancer risk
Two new reviews "Olive oil consumption seems to exert beneficial actions in terms of cancer prevention", the other review  "No significant association with cancer risk was observed". Psychologist Guy (talk) 22:07, 27 October 2022 (UTC)

Consumption per capita
The text was edited at some point to say that San Marino has the greatest per capita consumption of olive oil, and not Greece as was stated earlier.

I have a few concerns about this.

1) https://www.juanvilar.com/san-marino-es-el-mayor-consumidor-percapita-de-aceites-de-oliva-del-planeta/

This is not a proper wiki-worthy citation, are we supposed to trust a random consulting agency with zero data to back it up?

2) San Marino has a tiny population (34.000 people) making per-capita comparisons meaningless

3) The same source that was used for the edit puts Greece @12, Spain@11.7, Vatinacan @10.7 and Italy @8.2,

yet weirdly the person who made the San Marino edit did not bother to include this information but left it as "Greece, Spain and Italy, around 14 L;".

 * I'm not sure which edit you're talking about. My edit of 4 November did not change the part about San Marino, I simply changed the lead to match the article, as required by WP:LEAD. San Marino was added here: If you think the information is wrong feel free to change it. GA-RT-22 (talk) 14:40, 19 December 2022 (UTC)
 * It's an old edit indeed, I'm sorry if this was the wrong place to talk about it. Panosfirbas (talk) 14:45, 19 December 2022 (UTC)
 * This is exactly the right place to discuss it. It's not up to us to decide whether the San Marino number is meaningless. I'll see if I can update the numbers for the other countries. GA-RT-22 (talk) 17:35, 19 December 2022 (UTC)

Nutrition refs
The links for the refs in the Nutrition section to the USDA database aren't working for me. This one works: but it's to IA, it would be nice to get a live link direct to the USDA. GA-RT-22 (talk) 22:36, 25 December 2023 (UTC)


 * With this edit, I revised the section and updated the USDA source and URL for FoodData Central - the revised system of the National Nutrient Database since 2019. Zefr (talk) 07:06, 26 December 2023 (UTC)

Earliest find of olive oil source
Unless I missed some crucial information in my read through, the source for "The earliest surviving olive oil amphorae date to 3500 BC (Early Minoan times), though the production of olive oil is assumed to have started before 4000 BC" doesn't actually state that the amphorae dated from 3500BC; the earliest mentioned date I saw was 500BC ("As a result, scholars commonly assume that 5th-3rd century BC Greek amphoras carried wine"), which seems like a pretty significant misrepresentation to me.

 * I don't have a copy of the source. Please fix the text to match what the source says. GA-RT-22 (talk) 04:27, 17 March 2024 (UTC)
