Hormone disruption in a hurry! Peer-reviewed study finds that vegetable seed oil consumption triggers hormone dysregulation and ovarian toxicity in only 28 days.
My first memory of the insidious displacement of traditional healthy fats like butter with modern vegetable oils came in the form of Florence Henderson, of Brady Bunch fame, shilling for Wesson, a division of Blackrock-controlled multinational Conagra Foods.
Perhaps her most famous turn came from singing the earworm jingle “Wessonality” TV commercial.
Even as a kid, I thought that these commercials must be a subtle form of brainwashing.
I instinctively recoiled at the obvious and shameless grasping for control over the public’s wallet.
My mother thankfully never got sucked in by this dietary propaganda. She always cooked with butter. I never saw a bottle of vegetable oil in her pantry.
Another Nail in the Seed Oil Coffin
As the decades have passed, more scientific research has emerged about just how unhealthy modern vegetable oils are in the human diet.
It’s long been known that factory fats actually make you fat, unlike nourishing traditional fats which facilitate a healthy weight.
In addition, the journal Open Heart found that omega-6 polyunsaturated fat linoleic acid is likely a major dietary culprit for coronary heart disease, especially when consumed in the form of industrial seed oils commonly referred to as ‘vegetable oils’. (1)
Hormone Disruption in 28 Days!
Now, early research is indicating that vegetable oils are likely hormone disruptors as well.
The study examined both GMO and nonGMO varieties of sunflower, corn and canola oil.
Without exception, they discovered that in every case, consumption resulted in “remarkable estrogenic properties.” (2)
Not only did these oils disrupt hormonal function and trigger ovarian toxicity in the form of atrophy, congestion, and follicular cysts, but it happened in short order …. less than one month of exposure in rats!
What’s even more surprising is that the study didn’t include soybean oil, which captures 60% of all oil consumption in America.
Soybean oil is already known to be hormonally disruptive as it literally decreases happiness when consumed.
This occurs through destruction of oxytocin pathways, the bonding “love” hormone. (3)
Could so much soybean oil in the modern diet be partly responsible for why so many people feel isolated and intolerant of each other?
Possible Causes of the Estrogenicity of Vegetable Oils
The researchers called for human testing to identify the methods of hormone disruption caused by vegetable oils.
They postulated that it could be the phthalate and xenoestrogen contamination of the oils that is the culprit.
The violent processing and plastic packaging of seed oils can result in residues of these estrogenic substances polluting the oils themselves.
Phthalate contamination is especially high in sunflower oil, according to a Turkish study. (4)
In addition, it is very high in vegetable oils that are stored in polyethylene terephthalate or “PET” (recycling #1 in the US). (5)
Whatever the causative reasons for the contamination, informed consumers would be wise to avoid these industrial oils like the plague and any processed foods that contain them.
It is especially important to protect growing children from the hormone-altering effects of exposure to these oils in the diet as the repercussions could have lifelong effects to fertility.

I am also curious about Black seed oil. My Dr. has me taking it to reduce cholesterol. 100%pure virgin cold pressed. I would not normally be concerned about really high cholesterol since I’m very healthy and have followed weston price diet for many years. Heart disease, blood clots etc run in our family. Lost a brother very young to heart attack & another had stroke at very young age. Recently did an advanced cholesterol test and that also showed I was high risk. supposedly black seed oil has been used for thousands of years in traditional medicine. Would love to hear what you think of it if you ever get a chance to research.
Excess of omega 6 is bad any way you look at it. They promote inflammation and their easy rancidity degrades cholesterol. We have a traditional cold pressed oil with an omega 3 to omega 6 ratio of 1:1 which is mustard oil. You just have to ensure that it’s non GM
Olive oil has been used without repercussions for millennia, so if it is also harmful now, it’s GOT to be due to contamination.
Olive oil is fine and was not part of this alarming study. The study examined the modern oils never used traditionally such as corn, sunflower and canola oils.
That said, I highly recommend buying your olive oil DIRECT from the farm. Most olive oil you buy at the store is cut with cheaper oils like soy or canola…it is not 100% olive oil. This includes “restaurant” grade olive oil … mostly other types of oil yet called olive oil.
I have read a lot about Turkish black seed oil. Taken internally and also rubbed on the skin it seems to help with many body issues including inflammation. Do you have any thoughts or information about black seed oil?
I have not looked into this oil.
I tried it as a supplement-broke out in a rash on my skin. Guess it’s not for me.
What are your thoughts on black seed oil? I was using it each morning for health benefits but now I question whether I should be using it since it’s considered a seed oil as well.
I have not looked into this oil. What is the seed source?
100% cold pressed extra virgin black nigella seed oil is what I was using.
What about Andreas Seed Oils; he claims they saved his life?
You spoke about how horrible vegetable oils are, but then which oils do you recommend?
Thank you, MB Ray
This is what I use. https://www.thehealthyhomeeconomist.com/five-fats-you-must-have-in-your-kitchen/
So is peanut oil bad for you? We use it in baked goods. We also use EVOO when lightly frying things. Is that a no-no as well? Or are the only ones we should avoid soybean, vegetable, corn, canola and sunflower oils?
Here are my thoughts on peanut oil. https://www.thehealthyhomeeconomist.com/peanut-oil/
