Seed oils are listed in the ingredient list, not the nutrition panel. Read the list in order, because ingredients run by weight from most to least, and look for any word ending in "oil," plus "shortening." The seed oils most common in packaged snacks are soybean, canola, sunflower, safflower, corn, cottonseed and grapeseed. If a label says "vegetable oil" or uses "and/or," the package won't tell you which oil is actually in the bag.
What counts as a seed oil?
A seed oil is a cooking oil pressed or extracted from the seed of a plant rather than from a fruit or a nut. Soybean, canola, sunflower, safflower, cottonseed and grapeseed are the ones you'll meet most often in packaged snacks, and corn oil usually gets grouped in with them. Olive oil and avocado oil come from fruit. Coconut oil comes from the flesh of the coconut.
Where do seed oils show up on a label?
In the ingredient list. FDA rules at 21 CFR 101.4 require ingredients to be listed by their common or usual name in descending order of predominance by weight, heaviest first. An oil near the front of the list is a large part of what you're buying.
One exception is worth knowing. Ingredients present at 2 percent or less by weight can be grouped at the end of the list out of order, as long as they follow a line such as "Contains 2% or less of."
The nutrition panel tells you total fat. It doesn't tell you which fat.
The names to look for
Soybean oil · Canola oil (also rapeseed oil) · Sunflower oil · High oleic sunflower oil · Safflower oil · Corn oil · Cottonseed oil · Grapeseed oil · Sesame oil · Vegetable oil · Vegetable shortening · Blend of vegetable oils
Why does "vegetable oil" not tell you which oil it is?
This is the part most people miss. Under 21 CFR 101.4(b)(14), each fat or oil normally has to be declared by its specific common name, for example "cottonseed oil." Blends, though, may be written as "vegetable oil shortening" or "blend of vegetable oils" with the individual oils in parentheses.
The same rule goes further. A manufacturer may list oils that aren't actually in that particular product, as long as the wording signals they might not be present. The regulation names the accepted wording: "or," "and/or," and "contains one or more of the following."
So a list reading "vegetable oil shortening (contains one or more of the following: cottonseed oil, palm oil, soybean oil)" is accurate, and it still doesn't tell you which oil you're eating. If you're avoiding one specific oil, "and/or" is your signal to put the bag back.
Can "spices" or "natural flavor" hide an oil?
Not a seed oil, but they do hide detail. Under 21 CFR 101.22, spices may be declared collectively as "spice" or "spices" without naming each one. "Natural flavor" is defined in that same regulation and can include essential oils, oleoresins and extracts. Those are flavor extracts, not seed oils.
The point is narrower than the internet usually makes it. These terms are legal and common. They mean the components aren't named, so you're trusting the brand instead of reading the label. Where a spice blend is the whole point of the product, we think it should be spelled out.
Why do so many roasted nuts contain oil?
Seasoning needs something to hold it to the nut, and oil is the usual answer. Plenty of nuts are also roasted in oil rather than dry roasted. If you're looking for roasted nuts without seed oils, check the first three ingredients. On most flavored nuts, an oil is sitting right near the top.
Once you know the pattern you can check a whole brand in about a minute. Ours are here, every flavor with its full label.
Why are people avoiding seed oils?
Seed oils are one of the most argued-over ingredients in American food right now. In a February 2025 survey of 1,000 US adults, the International Food Information Council found 28 percent actively avoiding seed oils, with three in four at least somewhat familiar with the term.
The reasons people give usually come down to a few things. Seed oils are high in omega-6 linoleic acid, they make up a much larger share of the American diet than they did a century ago, and getting oil out of a seed takes industrial refining. Concerns about inflammation come up most often. Researchers are still arguing over how much of that holds up, and we're not going to pretend we can settle it for you.
What we can tell you is what's in the bag, and that turns out to be the harder problem.
Can you trust the oil named on the label?
Not always, and the clearest evidence comes from avocado oil, which is what a lot of people switch to when they cut seed oils.
Selina Wang and her team at the University of California, Davis have been testing avocado oil for years. In 2020 they reported that most of the commercial bottled avocado oils they tested were either stale before their expiration date or mixed with other oils, and some bottles labeled "pure" or "extra virgin" were close to 100 percent soybean oil.
In 2026, the same team tested finished products rather than bottles. Of 54 packaged foods sold as being made with avocado oil, including chips, dressings and mayonnaise, 48 were not consistent with pure avocado oil. In that sample, most products sold on the strength of avocado oil weren't pure avocado oil.
The olive oil products they tested were overwhelmingly pure. Olive oil has been tested for decades and has real standards behind it. Avocado oil is newer and more expensive, which is where the substitution happens. Oil itself isn't the villain. A premium claim got ahead of the testing.
So why doesn't Sivaro use them?
Not for medical reasons. We're not making a health claim, and we'd be suspicious of anyone in our category who does.
The first reason is the one this whole article is about. You can't reliably tell which oil you're eating. The "and/or" rule lets a bag name three oils and contain any one of them, and the UC Davis work shows that even a specific, expensive, named oil is sometimes something else. We're not going to build a label promise on top of that.
The second reason is that oil on a flavored nut is doing a job, not adding flavor. It holds seasoning to the nut. Maple syrup does the same job, it actually tastes like something, and it's already in your kitchen.
If it doesn't belong in a home kitchen, it doesn't go in the bag.
On a Sivaro label
Sivaro Snacks is a small-batch nut and dried fruit brand in Queens, New York. Our nuts are roasted in New York maple syrup with no seed oils, our dried fruit has no added sulfites, and every ingredient is on the label. Sivaro is MWBE, ACDBE and NMSDC certified.
Two examples of what spelling out every ingredient looks like.
Ceylon Curry Leaf Cashews. The curry powder is broken into its parts: red dry chili, coriander seeds, cumin seeds, fennel seeds, black pepper, turmeric powder, fenugreek seeds, garlic. Under 21 CFR 101.22 we were allowed to write "spices" and stop.
Smokey Almonds. The label reads "Smoke Flavor (Smoke, Water)." The more common version of that line is "natural smoke flavor," which doesn't show you what's in it.
Rice fiber appears in our nut bags. It absorbs moisture so the seasoning stays on the nut and the nut stays crisp. It does the job silicon dioxide does in a lot of packaged food, an anticaking agent approved under 21 CFR 172.480. We use rice fiber instead.
No seed oils appear in any Sivaro product, and no other added oil either. On the nuts, maple syrup does the binding.
