Is Olive Oil a Seed Oil? No — Here's the Difference
No—olive oil is a fruit oil, not a seed oil. It comes from olives. The International Olive Council defines virgin olive oils as oils obtained from the olive fruit by mechanical or other physical means. That tells you the source of the oil, but it does not mean that every other cooking oil is unhealthy.
Why the confusion?
Online discussions often use "seed oil" as if it described one manufacturing process or one nutritional profile. It is more helpful to ask three separate questions: what plant does the oil come from, how was it extracted, and what does the finished product contain?
Three things to compare
1. How it is made
Extra virgin olive oil is unrefined, and filtration is allowed. Seed oils are not all solvent-extracted: cold-pressed versions also exist. For example, a 2025 study of sunflower kernels examined mechanical cold pressing and measured oil extraction yields. It would therefore be incorrect to say that useful amounts of seed oil cannot be produced by pressing.
2. What's in it
Do not assume that all seed oils have the same composition or no vitamin E. The US National Institutes of Health lists sunflower, safflower and corn oils among food sources of vitamin E. Check the nutrition information for the specific oil you are comparing.
Canada's Food Guide includes olive oil as well as several seed oils among sources of healthy fats. Choosing extra virgin olive oil for its flavour and unrefined character does not require calling those alternatives harmful.
3. How you plan to use it
For a bread dip or finishing drizzle, choose an oil whose flavour you enjoy. For cooking, follow the recipe and the oil's instructions rather than assuming that "fruit" or "seed" alone determines suitability. For substitutions, see using olive oil instead of vegetable oil.
Is "extra virgin" the same as any olive oil?
No. The extra virgin grade must meet the IOC's chemical and sensory requirements, including free acidity of no more than 0.8%. An oil labelled simply "olive oil" can be a blend of refined and virgin olive oils. Read the grade, not just a description such as "pure" or "light".
What about olive pomace oil?
Olive pomace oil comes from the residue after olive oil extraction, using solvents or other physical treatments. It is a separate category, not extra virgin olive oil. Its processing does not turn it into a seed oil; source and processing are different questions.
How to compare bottles
- Check the grade and origin. Read the label and identify which product is being offered.
- Check dates and documentation. A test report should identify the sample it covers; do not assume it applies to every lot.
- Choose your flavour and format. Taste helps you decide what you enjoy, but it is not proof of a polyphenol value or certification.
Golden Spoon's olive oils
Golden Spoon extra virgin olive oil is cold-pressed from Chemlali olives in Tunisia and shipped from Ottawa. Our certified organic oil is the fuller-flavoured style; our Naturally Smooth oil is milder and is not certified organic.
Our published lab reports and certificates describe producer samples and certification details. They do not guarantee a polyphenol level for every product or lot. Read the polyphenol guide for the sample result and its limitations, or compare our full olive oil range.
