Dangers of Vegetable Oil Natural NigerianSource

Vegetable oil is a generic term that encompasses oil expelled from soybean, corn, cottonseed, and rapeseed (canola).  These highly liquid oils are a relatively new innovation.  They emerged on the scene in the 1920s and their level of consumption has since skyrocketed.

This is where things begin to get interesting.  Before the advent of vegetable oil, chronic diseases like heart disease and cancer were virtually non-existent.  Of course, correlation is not necessarily causation.  And one readily admits that chronic disease is caused by a number of factors.  However,  there is something uniquely toxic about vegetable oil.  Consider the observation of Dr. Dudley White, a respected American physician from that era: “See here, I began my practice as a cardiologist in 1921 and I never saw a heart attack patient until 1928. Back in the heart attack free days before 1920, the fats were butter and lard and I think that we would all benefit from the kind of diet that we had at a time when no one had ever heard the word corn oil.”

The problem with vegetable oil

Corn and soybean have been consumed by man for millennia.  Then, how is it that oil extracted from these wholesome foods is suddenly toxic?  Well, the problem is not the oil per se, but how that oil is modified to extend shelf life.

You see, highly liquid vegetable oils, also called polyunsatured fats, very quickly become rancid when exposed to air.  When you extract these fats from the protective context of a whole food, they break down quite rapidly.  That is, polyunsaturated fats are only stable when encased by and associated with proteins, carbohydrates, antioxidants, and other substances found in whole foods.  In fact, unmodified vegetable oil becomes rancid in a matter of hours when exposed to air.

This begs a question.  How then does commercial vegetable oil have an average shelf life of two years?  Vegetable oil is preserved by a process called partial hydrogenation.  In which, a fraction of the unstable polyunsaturated fats are converted to much more stable trans fats.  And it is these trans fats that give commercial vegetable oil their unnatural shelf life.

The producers of vegetable oil then have the audacity to paste boldly on their labels: CONTAINS NO TRANS FATS. This is a big fat lie. Sadly, this is but one instance of the vicious logic of the processed food industry, whose motto is profit over people.

The negative health effects of hydrogenated oils

Another term for partial hydrogenation is plastic-ization.  That is, natural oil is converted into a synthetic plastic-like substance.  Of a truth, commercial vegetable oil has more in common with petrochemicals than say naturally stable palm oil or coconut oil.  What do I mean?  Well, both petrochemicals and hydrogenated oils have no place in animal physiology.  They are invariably toxic whenever ingested, a true disadvantage when using vegetable oil.

No wonder that wherever petro-vegetable oil goes, an epidemic of chronic diseases is sure to follow.  In sum, the best oils for cooking are those that have been used in ancestral societies; namely palm oil, coconut oil, Shea butter, and animal fats.

Lord, what’s a lady looking to eat healthy to do. All this mislabelling, harmful ingredients in food, I’ll just stick to palm oil and coconut oil.


Loving your site! Just came across your site last night while looking for shea butter recipes.

I’m Nigerian and I know how our people hate anything made in Nigeria or on the continent. Reading this alone should convince people to stop paying too much attention to marketing and labels. I buy my olive oil from Costco because it’s cheaper and Costco has good products. If I see OO from Morocco, Spain, Tunisia – I’ll be all over it. In fact, I think Costco has a Mediterranean OO blend.


Hi, I follow you on twiiter and I clicked on your blog link. I use Galilee virgin Olive oil from Israel. Is this an original product?


Please Natural Nigerian, permit me to go off topic a bit. I’ve just finished reading all your blog posts from start to finish. 44 pages. With my phone. Started about a week ago lol. Even though I discovered your blog in the last quarter of last year. I can fully say u r my natural living inspiration lol. I’m relaxed but will BC in a few days. Anyway onto my question. What do think about using baking powder as a deodorant? Commercial deodorants/antiperpirants give me lumps in my armpit. For a long time now. Just noticed it was caused by antiperspirants. Slow me I know lol. Went on d web for a natural remedy. So now I swab with ACV, rinse off, bathe with dudu osun and dust baking soda on armpits. For a few days now. No lumps n I pretty much stay dry n odour free till d end of d day. What do u think? Sorry for d long post lol

Hey Mitchell, I am really humbled that you took the time. Makes slaving away over my Mac worth it. Lol! I have never tried baking soda under my arm. If it is working for you, them go for it. My only problem is the fact that it is the only thing you use. Baking Soda naturally has a high pH and having it sit against skin all day concerns me a bit. There are other things that should accompany it. Some recipes here. Also, try using a lemon. Just swipe under your arm at the beginning of your bath, rinse off at the end of it and go about your day. Lemon juice pH is lower and closer to the acid mantle of skin.

I used to suffer from bumps but found out that it was my hair removal method that was the problem – I am just not built to shave. Shaving for me is like jumping into a vehicle and heading straight for bump central – and not the small polite ones. These ones were huge and painful. I resorted to waxing and the bumps were gone almost overnight.


I’m asking you based on your credentials as a natural chemist 😀 Cause I think I feel a lump coming on but I’m thinking it’s left over from my antiperspirant days. I got tired of treating with antibiotics ’cause they didn’t work. Think my body grew immune to them. So I pretty much left d lumps to their own devices. Painful tho. So I used painkillers. Ok ok. I’ll stop here 🙂


Thank you very much for replying. Lool kpele about your bumps. Lemons eh? Actually saw those online too. But not so easy to acquire. Nevertheless I’ll try n get some. Anything but going back to lump-inducing antiperspirants. And lemons supposedly have to lighten dark underams over time. Win win!

Hello.. so the article isn’t really showing anymore. I’ve loaded the page several times, read the comment but not the article. .


I can’t seem to load other contents of your website. Read the post about vegetable oil and tried getting to Olive oil post but didn’t work. It keeps putting up the vegetable oil post’s content with the olive oil post’s heading. Hope that makes sense and hopes this gets through. Thanks!
