Is olive oil a seed oil? A ruling on 12 oils, plus olive oil blends and avocado oil purity.

Updated

Olive oil is not a seed oil: it comes from the fruit. A ruling table for the oils our checker flags, the “olive oil blend” trap on labels, and an attributed note on avocado oil purity.

Quick answer

No. Olive oil is pressed from the olive fruit, not from a seed, and our checker does not flag it as a seed oil. The oils it does flag are canola (rapeseed), soybean, sunflower, safflower, corn, cottonseed, grapeseed and rice bran oil, plus generic “vegetable oil”. Labels that say olive oil blend can still list a seed oil beside it, so read the whole list.

Seed or fruit?

A seed oil is pressed from the seed of a crop plant. Olive oil is pressed from the flesh of the whole olive fruit, so it sits with avocado and coconut oil as a fruit oil, not with canola or sunflower. That is the botanical answer, and it is also how our checker works.

The ruling.

The checker flags a label when it names one of these oils. The first twelve names below are flagged under seed oils; the oils after them are not.

The blend trap.

Some bottles and foods use olive oil in the name but add canola, soybean or sunflower oil to lower the price or change the flavor. The ingredient list tells the truth: a blend lists more than one oil. The table on this page counts how many olive oil labels in our catalog also list a seed oil.

04 · A closer look

A note on avocado oil.

Avocado oil is also a fruit oil and is not flagged. A 2020 UC Davis study reported that most of the commercial avocado oils it tested were either stale before their date or mixed with other oils. That is one study, and there are no enforceable US standards for avocado oil purity, so a label that lists only avocado oil is the thing to look for, and a very low price is a reason to read more carefully.

How the clean score works

No setup needed, and strict: a full 100 needs every additive group clear and a verified organic claim (animal foods also need a verified grass-fed or pasture-raised claim; wild seafood and salt, which have no USDA organic standard, are scored without the organic points, and plant-based milks, cheeses and proteins without the feeding claim). Points: the nine additive groups (seed oils, artificial dyes, MSG, artificial sweeteners, carrageenan, artificial preservatives, hydrogenated oils, corn syrups, banned-abroad additives) share 60 points equally — not found earns a group’s full share, “may contain” earns half, listed earns 0; a verified organic claim is worth 25; a verified grass-fed or pasture-raised claim is worth 15 and counts only for animal foods. No claim, or an expired or unverified claim, earns nothing, so products without those claims cannot reach 100. Unverified or expired ingredient labels receive no score. Equal scores are equal. Ties are ordered by brand. Unknown and stale evidence never passes “Only show matches.” Producer claims and prices do not affect this score. This is not a nutrition, allergy, or safety rating.
