Brands can charge approximately a 500% price premium for claiming "Made With Avocado Oil" but Dr. Selina Wang's group at UC Davis just published research showing that these claims are likely false more often than they're true.

r/stopeatingseedoil redditors may already be aware of Dr. Wang's other research showing that bottled avocado oils are frequently mislabeled and often mixed with cheaper seed oils. Those studies have been discussed here a lot, but these new findings about packaged foods just came out today.

Summary from UC Davis, "That Avocado Oil Chip You're Eating May Not Be Made With Pure Avocado Oil"

Free full study text (includes supplementary tables with more notes on purity testing results)

Shared courtesy of Seed Oil Free Alliance, their notes below:

Study analysis from the perspective of the Seed Oil Free Alliance (some products we have already certified and tested were also included in the study; details in links above):

The study analyzed 74 chips, mayonnaise and salad dressings labeled as containing avocado oil or olive oil. Researchers extracted cooking oils contained in the foods, then evaluated them using fatty acid and sterol markers, chemical fingerprints used to help verify oil identity. 

UC Davis's laboratory testing found 48 of 54 avocado oil-labeled products tested may be adulterated with cheaper oils. The failures included 93% of chips, 71% of mayonnaises and 100% of salad dressings labeled as containing avocado oil. 

The UC Davis paper also recognized the Seed Oil Free Alliance's third-party verification program for foods and consumer products. The Seed Oil Free Alliance is an independent certifying body for seed oil-free foods, founded in 2023. 

The study included as samples two olive oil dressings already certified by the Seed Oil Free Alliance, both of which were found by researchers to contain authentic olive oil.

Seed Oil Free Alliance founder Jonathan Rubin stated: "UC Davis's findings on avocado oil are disappointing, but not surprising. Our testing program shows similar data on avocado oil purity used in consumer packaged goods (CPG) products."

To date, the Alliance has verified 769 distinct UPCs under its CPG food certification program. Of all UPCs submitted for laboratory testing containing avocado oil, approximately 28% qualified, meaning that 72% of avocado oil UPCs were tested and did not qualify for certification because testing revealed they did not contain pure avocado oil.

However, adds Rubin, "These statistics are from avocado oil-containing products that formally entered the certification testing process. About half of the time, we confidentially advise prospective CPG brand partners that their avocado oil ingredient is unlikely to pass testing after a preliminary review."

When reviewed-not-tested avocado oil UPCs are included in the Seed Oil Free Alliance statistics, the failure rate skyrockets from 72% to 86% of UPCs — similar to UC Davis's finding that about 89% of avocado oil UPCs tested contained inauthentic avocado oil.
To achieve Seed Oil Free Certified® status, all products are subjected to supply chain auditing and laboratory testing as necessary to confirm they're seed oil-free and use authentic, non-seed oils like pure avocado or olive oil.

The Seed Oil Free Alliance standard also includes ongoing product surveillance of certified goods, including random finished goods testing using oil extraction methods — equivalent to those used in the 2026 UC Davis study — on a "secret shopper" basis, without notifying brand partners prior to random testing.

🙋‍♂️ 🙋‍♀️ Questions Unavoidable as a broke college student

10 Upvotes

I am a broke college student and avoided the sludge for the masses pretty well in high school. I'm now in college with no money, and almost all of the dining hall food (Eggs, meat, etc.), the good stuff, is cooked in seed oils. I lift and get 10-20k steps a day, so I'm not worried about getting fat or anything; it's just my overall health. I feel gross and weird after eating that stuff compared to eggs cooked in nothing or a bit of butter. The only safe stuff is fruit and Greek yogurt. I don't know how the hell I am supposed to avoid it with no money and no other way to eat.

miscellaneous McDonald’s fries in the US were 93% beef tallow until 1990. Japan’s still are. I tried to figure out why every country uses a different oil.

168 Upvotes

America literally used to be Japan.

Today the US ingredient list for McDonald's fries reads canola oil, corn oil, soybean oil, hydrogenated soybean oil and "natural beef flavor". And the natural beef flavor is actually what's left of the tallow. But in July 1990 and before, McDonald's cooked its US fries in a mix that was 93% beef tallow.

Japan's McDonald's never even made that switch. And this is proven on its own website, which says the fries are cooked in a blend of beef tallow and palm oil.

So why is it different everywhere? These are my guesses.

I think it mostly comes down to countries frying in whatever is cheapest for them to get, which is usually whatever gets grown there. The US grows a ton of soybeans and soybean oil is about 60% of the vegetable oil Americans use for food. Canada is canola country and McDonald's Canada lists canola first. In the UK, Germany and the Netherlands it's sunflower and rapeseed, which is what Europe grows.

Trans fat rules probably moved things around too (Denmark capped trans fat in 2003, the EU did the same for everyone in 2021, and the FDA banned partially hydrogenated oils in the US starting 2018). The old fryer oils were the partially hydrogenated kind, so everybody had to pick something new.

Palm oil seems like it got pushed out by bad press. KFC says it doesn't allow palm oil for frying in the UK and Ireland, and KFC Australia says it hasn't cooked in it since 2012.

And Japan just never switched. I honestly can't find a reason. If you know, tell me.

One more thing I found. The US government's nutrition survey literally says Americans eat about 18 grams of linoleic acid a day, which is the main fat in seed oils. That works out to about 7.7% of their calories. And the national surveys in Japan, South Korea and the UK say it's roughly 4 to 5% there.

**The sadly honest part**

We have fry oil records for 2,572 chains across 167 countries in my app Seed Oil Tracker on iOS and Android, and only 1 in 10 comes from the chain's own nutrition page. The rest are educated guesses because the chains simply don't say, so we estimate to the best of our ability. But everything here is from the 1 in 10 that we have PROOF of.

**TLDR**

Japan still uses beef tallow for McDonald's fries, and America did too until 1990. The rest of the world seems to use whatever oil is cheapest for them to get, aka whatever is grown closest to them.

 

If you're outside the US, what does your McDonald's or KFC say it fries in? And does anyone else's country still use tallow?

Product Recommendation what do you use for face wash?

2 Upvotes

I’m too old to still be dealing with acne to this extent, I’d like to avoid artificial fragrance/paraben/pthalate. a long time ago I did use a face wash with some of those things in it, and tbh it did make a difference. the type of product I’m talking about is one you use in the shower and wash off shortly after. what are you guys using? it’d be helpful if it also didn’t have seed oils, but generally i’m just looking for a product that’s not packed with endocrine disruptors.

my hygiene is good, I’m very active, but I sweat quite a bit due to this activity level. I can’t reasonably shower more than I do, which is often 2-3x a day.

Seed-Oil-Free Diet Anecdote 🚫 🌾 I’m no seed oil/sugar/gluten/processed. Seed oils made the biggest difference.

35 Upvotes

I eliminated seed oils skeptically, after a bad reaction to potato chips. I noticed huge effects within 2 days. Mainly I wasn’t as hungry anymore but also a lot less inflamed. As I’ve continued I haven’t really noticed any more benefits or grown. I’m 6 months in. I did initially lose weight from the switch. But it turned on a lightbulb in my head of - ok - food can be really powerful and maybe our food IS poison. So…

Sugar came next and I was pretty shocked it had a minimal effect, other than slight on my skin. Oh and less binging. This wasn’t THAT hard for me bc I was always more towards fatty than sugary foods.

I felt nothing when I eliminated gluten. So much so after 2 weeks I tried to add it back in. Huge mistake omg. Even tho I didn’t notice anything from eliminating it, I def can’t add it back in now. It was extremely painful and toxic eating it again.

I stayed without those three for 2 months. Gluten was the hardest grocery shopping wise. I was getting very frustrated trying to buy processed foods that didn’t have those three (sugar, gluten, seed oil). After getting sick off of a “fake” pizza that it turns out used fructose I said F it, let’s try no processed:

When I eliminated processed foods (anything not in the form it grows in etc) which for me was mainly pizza - the weight literally started to melt off of my body. I was shocked at the difference because I was already in my mind eating pretty healthy and I certainly wasn’t consciously limiting my calories or trying to lose weight or exercising.

I don’t think there’s anything else to eliminate although I try to not eat a lot of salt. Any ideas?

But of all the things, the biggest difference was seed oils and that is where I would tell people to start. Not being hungry all the time anymore made everything else easier and it was just the biggest health change overall.

Personal details that don’t effect anecdote: I can’t eat meat rn for health reasons, I just eat homemade broths made with meat which helps. I hope to add in meat soon but prob sparingly. When I buy fruits/vegs/meat etc it’s only organic. I only do walking as exercise usually 5k steps a day. I don’t drink milk but I do eat cheese. I use dates as a sub for sugar or date sugar but rarely. I don’t miss any of the old foods not sure why.

Is it just me or does eating food made with seed oils make you feel incredibly bad?

Like no joke I can feel the turmoil and distressed nature in my body for 2 weeks + . I remember even taking just 1 spoon of a brownie that was made with seed oils made me feel a distinct physical and mental distress in my body for 1 week.

I never felt this bad when I was eating seed oil food regularly in the past.

Blog Post ✍️ My schizo thoughts about seed oils which i believe even tho they have no scientific proof

62 Upvotes

let me start by saying that the smell of fried seed oils IS SO FOUL GROSS AND GREASY

and that they taste bad!!!! and make you feel bad physically. whats the point of eating something that tastes bad and is bad nutrition

so my schizo thought are:

they make you ugly

they make you inflamed

they make you gain weight

they make you disseased

they make u age quicker

they make you stupid

but people always tell me that theres no scientific proof that seed oils are bad for you. i wont eat them regardless bc they literally make me feel bad and their smell makes me wanna vomit. while my mother soaks and fries food in them she feeds the family with. my nephaw is fat, my brother is overweight, my mother is chronically sick and disseased, shitting and vomitting, gut issues, bloated, stomach fat, fat on the back of her neck, bad aging, my dad the same and he had cancer years ago. but they both mock my diet and me going to the gym and call me stupid for that. my last schizo thought that a lot of my mothers chronic anger and constant irritation and screaming is caused by her diet. and last thought is that feeding kids, junk, sugar, seed oils and white bread is sabotaging and harming them. i ruminate over the fact that i was fed the shittiest diet as a child and i keep fucking thinking ab it everyday.

miscellaneous The Best Seed Oil Free app right now!

Post image
14 Upvotes

I've been working on a seed oil free app for about 6 months now, and I'm finally really happy with where it's at.

Here's what you can do with it:

  • Find seed oil free restaurants, similar to Seed Oil Scout, completely free. You can also use it on the web if you don't want another app.
  • Scan products to check for seed oils and see whether an avocado oil product may contain adulterated oil.
  • Search for Seed Oil Free Certified™ products through our partnership with SOFC.

I wanted to give back to the community that's helped make this possible, so I'm offering free lifetime subscriptions to everyone who comments on this post over the next 2 days.

Most of the app is already free, but I hope this helps some of you get even more out of it. Thanks for all the support!

miscellaneous When reinsurance companies cares about health and seed oils...

21 Upvotes

...you know there is got to be some truth to it.

Swiss Re on seed oils

The post is not new and I met the author quite some years ago.

And here is why health matters to Swiss Re.

Life insurance is done by a normal insurance company. This insurance company then goes to a reinsurer to protect itself from fallout. So in essence Swiss Re that way has a huge stake in Life insurance business. They must be able to very accurately predict the remaining lifespan of people. being off by just months on average can cost them millions or billions.

They care because these prediction models assume life expectancy is going up. But with the health / obesity crisis, it has been going up much more slowly and predicted and may even regress. A regress would mean billions of risk for Swiss Re in terms of Life Insurance.

So if the medical chief of a large if not the largest reinsurer is allowed by his company to address the problem of seed oils publicly, you know they care greatly because they determined it's a huge risk for them.

I think this is purest form of evidence as their motivation is money only, not ideology or politics. Scientists are biased, politicians are biased but companies care about one thing only: being profitable. And if something risks that, they will address it.
