Although not strictly a food, many of us consume vegetable & seed oils in very high volumes. More often than not, it is the most widely available cooking oil in the shops. It’s also what most restaurants use, & has been used to prepare any “pre made” foods that you buy.

So the answer to the question does vegetable oil lower testosterone is a resounding yes. It needs to the be recognised that any produce prepared with vegetable or seed oils are foods that lower testosterone and sadly it is a lot of foods!

So these foods need to be avoided as much as possible & due to lowering testosterone, but the presence of these oils also creates more health issues. We will be covering why these oils lower testosterone and negatively impact your health next.

Why Seed & Vegetable Oils Lower Testosterone & Cause Health Problems

I know this one will come as a shock for many of you, as vegetable oils are often promoted as being healthy. The fact is that any produce, made with them are foods that lower testosterone and that is just a part of the health issues they cause.

The main reasons seed & vegetable oils cause health such health problems are the manufacturing process their omega 6 levels. They are extremely high in omega 6 fats and low in Omega 3. Conventional wisdom is that ratios are meant to be 4: 1 in favour of Omega 6.

Even that is quite often questioned & in a lot of circles a ratio closer to 1:1 is considered best for health & reducing aging. The reason Omega 6 is a problem is that in high amounts, it causes inflammation. Inflammation means that the body isn’t working properly. 

That stops the body from performing all of it’s bodily functions properly this includes testosterone production. Most vegetable & seed oils are very high in omega 6, with sunflower, soybean, corn & cotton seed oil being some of the highest.

So now we’re going to look at the big thing, that is how these oils are produced. These are now frequently referred to as industrial oils in health circles and you will see why!

This is especially for seed oils, the seeds are heated to extremely high temperatures. This leads to the unsaturated fatty acids oxidizing, which creates by-products that are damaging to human & animal health!

These oils are then processed with petroleum based solvents and then a number of chemicals are added to deodorize & improve the colour. This process also produces trans fats which are also bad for our health! On top of that, these oils are extremely refined!

So you can see why these oils and the produce that contain them aren’t just foods that lower testosterone but can also damage wider health.

What Do I Mean By Vegetable & Seed Oils

Seed & vegetable oils includes quite a wide range; but the ones most commonly available & used are as follows:

  • Soybean Oil
  • Sunflower
  • Canola
  • Peanut
  • Cottonseed
  • Corn Oil

Just to talk soybean oil a little bit, there have recently been rate studies published, that showed that soy bean oil to be more of an obesogenic & diabetogenic than fructose. 

Another study in to soybean oil rats, showed that soybean oil causes neurological damage! While rat studies don’t always translate to humans, we know that these oils are already unhealthy. These findings just adds further fuel that they need to be avoided!

So Where Are These Oils Found


As covered previously, vegetable & seed oils are found in most “pre-made foods” and they are also a heavy feature in processed foods.

These are some of the main places you will find seed & vegetable oils:

  • Meat Replacements/ alternatives
  • Margarine
  • Vegetable Spreads
  • Crisps/ Potato Chips
  • Baked Products
  • Pastries
  • Battered Foods
  • Junk Food (Pizza, burgers etc,)

So What Types Of Oils Should You Be Eating

Coconut Oil

There is a well documented study from the 90’s which clearly demonstrated that human male tests subjects, saw a decrease in testosterone levels with an increase of polyunsaturated fatty acids in their diets (oils high in omega 6 like vegetable & seed).

They saw an increase in testosterone levels with an increased amount of Saturated Fatty acids in their diet. As that study indicated, saturated fats & monounsaturated fats are best as far as testosterone production is concerned.

They are also great for your health, first off they aren’t high in omega 6, in fact they are good sources of omega 3. The omega 3 actually lowers the inflammation caused by omega 6, so your testosterone levels & wider health benefit from that.

Then saturated fats in particular also provide cholesterol & cholesterol is the main building block of testosterone. So for me the best cooking oil for testosterone is coconut oil. A great source of saturated fats, cholesterol and antioxidants. 

Secondary choices are monounsaturated fats like olive oil (make sure it’s pure) and avocado oil. These oils will not only boost testosterone; but using them in place of seed oils will improve health as a whole!

  3. Richard says:

    Wow , thanks for the post I wasn’t aware that vegetable oil will lower testosterone , I guess I will be switching from peanut oil to coconut or olive oil.

    1. Nate Stone says:

      Hi Richard,

      Yes vegetable oils are highly processed and high in UFA’s which increases inflammation and lowers testosterone production. If you are adding an oil to salads I’d recommend Olive Oil, if you are cooking I’d recommend coconut oil.

  4. Rick says:

    wow , thanks for the post I didn’t realize the effects vegetable oil could have on testosterone levels . I guess I will be switching from using sunflower oil to coconut or olive oil ..

    1. Nate Stone says:

      Hi Rick,

      I’m glad you found this article useful!

      If you are adding an oil to salads Olive Oil is best, if you are cooking I’d recommend coconut oil, be careful cooking with live oil as it has a fairly low smoke point and if cooked at too high a temperature, you lose the health benefits.

    This article was just full of surprises for me. For long I though vegetable oil is a really healthy choice for human beings but it looks like it is not as much as healthy as it is advertised. Learned a lot about Omega 6 and testosterone production in this article. Thank you so much for sharing this article with us.

    1. Nate Stone says:

      Hi Sujandar, 

      I’m glad you found the article useful!

      Yes unfortunately vegetable oils aren’t healthy as they’ve been advertised, I’d advise opting for organic coconut oil as the best choice for cooking with.

  7. DerrAd says:

    Vegetable oils lower testosterone?! You’ve done pretty well explaining why vegetable oils cause reduction in testosterone but I must say it’s hard for me to accept since I’m eating it almost every day. I guess the harm has already been caused but switching to coconut oil going forward might be helpful, right? 

     Thanks for providing such a valuable info.

    1. Nate Stone says:

      Hi Derrad. 

      Yes unfortunately some of the damage will already be done; but fortunately your testosterone levels fluctuate and can be increased by lifestyle changes. Swapping your main cooking oil to coconut is a good start to increase your testosterone levels, I’d also advise checking out this article on things that lower testosterone so you know what else you need to avoid.

  8. Alicia says:

    Very interesting article on vegetable oil.  Strangely, this is the second article I have read in 24 hours that warns that vegetable oils may not be as healthy as we have been led to believe.  I’m a big believer in everything in moderation though.  I did not know this about lowering testosterone so thanks for sharing.

    1. Nate Stone says:

      Hi Alicia, 

      I’m glad more people are starting to educate other on this subject, yes the main issue is that the process which vegetable oils go through to make them strip any natural health properties. 

      To be honest vegetable oil has very little healthy benefit, yes it lowers testosterone production but it also caused many other health issues. I’d advise swapping out for coconut oil and olive oils.

    It is interesting to read about the cooking oils and testosterone levels. I didn’t know that vegetable oil was one of the foods that lower testosterone.At my house we eat it all the time and it seems to be ok. I guess if you are right I have to rethink the oil we use to cook.

    It seems you recommend coconut oil and I might give it a try. You say you use it a lot so does it taste good? i don’t mind the taste of coconut when it is natural.

    As I say I will try the coconut oil but I haven’t noticed any weird feelings from the use of vegetable oil. Now that I’ve read about this I will have to think about it more.



    1. Nate Stone says:

      Hi Tommy, 

      Yes it  vegetable oils do lower testosterone; but not only that they cause inflammation which leads to a number of other health issues. I’d advise swapping to coconuts for cooking, it’s quite sweet tasting. If you want something to add to salads, I’d advise using avocado oil to pour on salad etc.
