Foods That Lower Testosterone: Why Avoid Vegetable Oils

Why Look At Vegetable Oils At All

In this article we’re covering one of the most commonly consumed foods that lower testosterone production. Although not strictly a food, many of us consume vegetable oil in very high volumes. It’s the most commonly available “cooking” oil in super markets & it’s what most restaurants use, hence why it’s important you recognise it as one of the foods that lower testosterone so you can avoid whenever possible! If you’re unsure as to why having lowered T levels is an issue, I suggest you check out these Testosterone And Health Articles – They will give you a clearer idea of why having healthy T levels is important.

Vegetable Oils – What is The Issue

I know this one will come as a shock for many of you, as vegetable oils are often promoted as being healthy and they’re a staple cooking oil for many people; but vegetable oils aren’t great for your health as a whole & need to recognised as one of the foods that lower testosterone. This is largely down to them being high in polyunsaturated fatty acids (PUFA) and omega 6 fats. These lead to increased inflammation and higher inflammation leads to decreased testosterone production. PUFA’s are actually split in to two types, Omega 6 and Omega 3. Omega 3 tends to be found in fish, seafood etc. you need both omega 3 and 6 but most of us have way too much Omega 6 and too little Omega 3, you can find out a bit more about this and how to help optimise your ratios here on this Foods That Lower Testosterone – The Difference Between Omega 3 & 6

What Is Included As Vegetable Oils

Vegetable oils includes quite a wide range of different oils; but the ones most commonly available & used are as follows:

  • Sunflower
  • Canola
  • Peanut
  • Cottonseed
  • Corn Oil

How Different fats Effect Testosterone Production

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 PUFA

• Saw an increase in testosterone levels with an increase of Saturated Fatty acids

• Saw increased total fat intake boost testosterone levels

In short an increase in fat is good for Testosterone production; but it has to be the right type of fats. So what you’re looking for are saturated & monounsaturated fats and to avoid PUFA’s which vegetable oils are a big source of. The other issue with vegetable oils on top of potentially being high in Omega 6 are they’re very processed, this strips the majority of any natural health benefits out!

Omega 6 & Testosterone Production

As mentioned vegetable oils can lower testosterone even further if they’re high in omega six due to them increasing inflammation. In fact any food high in Omega 6 & low in/ without omega 3 you should be wary of, as these are normally foods that lower testosterone production.

The oils you want to use are coconut (what I personally use), Olive & avocado. These are high in saturated or monounsaturated fats and the healthiest to cook with in general but especially for testosterone levels.

As I mentioned coconut oil is what I use personally, it actually provides you with multiple health benefits over aiding testosterone production. You can find out more about these health benefits and why you should include coconut oil in your diet here, in this article on why coconut oil is good for you

Final Thoughts

Hopefully this article has highlighted why vegetable oils should be considered one of the foods that lower testosterone production and has made you wary of any foods high polyunsaturated fatty acids/ PUFA’s & omega 6 for the same reason. I’ll be creating more articles in future deailing other foods to avoid high in PUFA’s & Omega and a big list of foods that lower testosterone. That way you’ll know what to avoid  moving forward & can have a guide to reference against.

      Hi Darren,

      I’m glad you found it useful!

      Yeah vegetable oils are poor for your wider health & especially your testosterone production!

  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.

  5. Caleb says:

    Shoot, I have too much testosterone! I think I’ll include a little bit more of this stuff in my diet! haha I’ll admit that I never thought about this before reading your article though, I was definitely informed! Thank you for this information, I’ll tell everyone I know!

    1. Nate Stone says:

      Hi Caleb,

      Wow too much testosterone is quite hard to achieve, yeah if you do have too much testosterone I wouldn’t necessarily go down the vegetable oil route as the are pretty bad for your health as a whole, if you need to genuinely lower your T levels, you’ll be better of checking out this foods that lower testosterone article

    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.
