Testosterone and food

Testosterone is crucial in making you the man you are. Without it, you would literally be a whole different person!

So what’s the science behind all this? Why is it that we need the big T so badly?

I’ll answer all those questions and more, and show you just how it is all linked to your diet. When it comes to your body, you really are what you eat.

After shortly explaining how it works I’ll give you that list of 5 testosterone killing foods; plus a little extra at the end…

T is for Testosterone

Testosterone is the primary male sex hormone. It’s not only found in all humans, but in several other animal species, mostly vertebrates, as well.

In men, the hormone is primarily produced by the testicles, while for women testosterone production mostly happens in the ovaries.

The testicles produce much more testosterone than the ovaries, and it’s testosterone which gives men those manly features;

  • Bigger muscle mass
  • More body hair
  • Stronger bones
  • Super sex drive

This is why we often see testosterone as a specifically male hormone. And this is why so many guys are desperate to boost their testosterone levels; and why they want to know the foods that reduce testosterone!

But before I get to that list of testosterone killing foods, let’s find out more about how your body actually regulates hormones like testosterone, and how it’s linked to what you eat every day…

Hormonal imbalance – and how it affects you…

Your hormones define who you are. They are your body’s messengers. They go through your bloodstream and tell your organs and tissues what to do. This internal messaging system is called the endocrine system.

Now the actual effects of them on your body is enormous. From controlling your metabolism to your mood; your hormones define you. So when the amount of a certain hormone in your body changes, it can have a big impact…

When this happens we call it a hormonal imbalance. An example is the combination of lower testosterone and higher estrogen in a man, causing weight gain, muscle weakness, and all sorts of related symptoms, as discussed in multiple studies.

Many factors can cause a hormonal imbalance, and your diet is one of them. Know exactly how it affects you and you can help control that balance by eating the right things, and knowing what foods to avoid at all times!

Foods and testosterone

Diet is just one of the factors that can cause your testosterone levels to decrease. The most common factors are:

  • Age; you lose testosterone as you get older
  • Chronic illness; such as Hemochromatosis or HIV
  • Medication; certain pain medications and steroids can affect the pituitary gland, which can impair the normal release of hormones
  • Obesity; too much body fat is linked to hormone production

There are many more factors on the list, but these – together with the foods you eat – are the top ones.

Some of these you can’t control (like age or chronic illness), but your diet you CAN control. You just need to know what to pay attention to…

When talking about foods and testosterone it’s not just about eating less (fat), it’s about what your food contains and what bodily processes it might affect.

You see, food can affect hormonal balance. Some foods, for example, actually contain hormones or nutrients that act like hormones (such as phytoestrogens, which you’ll see in the list of testosterone killing foods below).

Studies have suggested that such foods can negatively affect your hormonal balance.

Likewise, there are also good nutrients to boost your testosterone, such as Vitamin D and Zinc.

In the end it all works together and affects each other. So what you eat is incredibly important for your testosterone levels.

Now you know a bit about how it works let’s move on to that list of foods that kill testosterone. Think again next time you’re grocery shopping…

testosterone foods

Top 5 testosterone killing foods

Bear in mind that you can still eat the foods on this list as part of a healthy, balanced diet.

As always with your diet it comes down to balance and moderation. Just having the foods on this list every now and then won’t instantly sink your t levels.

However, they may reduce testosterone levels when eaten too much.

Know them, know what they do with your body, and adjust your diet where necessary.

dairy testosterone

1 – Dairy products

When growing up we’re taught to drink milk by the gallons every day, and who doesn’t love a good cheese?

Unfortunately, even though dairy has many positive effects it can also strongly impact your testosterone levels. The problem lies not so much in dairy itself, but more in where the dairy comes from.

You see dairy cows are given loads of antibiotics and hormones to grow them as quickly as possible and to prevent diseases that are natural to occur when you stuff so many animals in a tiny space.

It’s horrible, but it’s what happens, and all the crap they are given is passed through to us in the milk they produce.

This can seriously mess with your hormones and lower your t levels. No wonder dairy is at the top of our list of foods that lower testosterone!

Oh, and on top of all that cows are often fed soy, which in turn can increase levels of the female hormone estrogen. And that brings me to number 2 on the list…

soy testosterone

2 – Soy products

There’s a good chance you’ve heard it before; some big-muscle guy cursing at how vegetarians/vegans all grow moobs because of all the soy they eat and drink…

How exaggerated that might be, there IS a truth to it, studies suggest

Soy contains those phytoestrogens I mentioned earlier, and it’s those that may boost your estrogen levels and lower your testosterone levels.

As such, soy foods like tofu, edamame, soy milk and soy protein isolates may alter your hormonal balance. This makes soy one of the foods that increase estrogen in males.

Note: currently studies are divided and more research on the topic is still needed. For now though, I’d advise you just don’t eat TOO much soy.

licorice root

3 – Licorice root

Before you think “I don’t eat licorice so this doesn’t affect me”; think again!

Licorice root (or liquorice if you’re British) is actually often used in drinks or to sweeten candies, so there’s a good chance you might accidentally eat some licorice root every now and then. And funnily enough, licorice candy actually often DOESN’T contain licorice root!

Now as with everything, a bit of it doesn’t matter. In large quantities, however, studies have shown that licorice consumption might have an influence on hormone levels, decreasing your testosterone.

alcohol testosterone

4 – Alcohol

We all know how bad alcohol is, but did you know it also affects your testosterone levels?

A study published in 2017 reviewed the effects of alcohol on your body, including your testosterone levels. Their conclusion was that excessive alcohol consumption effectively lowers your testosterone levels.

First and foremost, it’s high in calories, so it causes weight gain. Not just any weight gain, though. Predominantly fat gain. Additionally, it causes a substrate to form in your system called acetate, which slows down your metabolism.

High calories plus slow metabolism equals weight gain in a split second.

Finally, and worst of all, excessive alcohol intake slows down your body’s release of testosterone. So you run the risk of getting fatter, weaker, and less defined in one fell swoop by partaking in regular drinking fests.

If you want to avoid this, keep away from the bubbly – or at least cut your intake way down and keep it low.

processed foods

5 – Processed foods

Those cheap ready meals and pre-packed snacks are not great for your health anyway, we know that, but aside from containing way too much sugar, salt, and calories they actually also decrease testosterone.

Processed foods often contain trans fats, which have been linked to loads of health complications, including lower T. Not only that, this study also suggests it reduces your sperm count!

You might want to cook your own food from now on…

… But the list doesn’t end here…

That’s right; it doesn’t end with these 5 testosterone killing foods.

Maybe you already knew the foods above, or maybe they didn’t come as a surprise. However, did you know there are also some true t-killers in disguise out there…?

So, as a bonus, I’ve added 3 testosterone killing foods that you probably NEVER expected to be on the list. You might want to avoid these!

mint testosterone

6 – Mint

I really didn’t expect this one… Who knew having a lovely spearmint tea could actually lower your T?!

For example, a study done in 2004 looked at the effects of mint herbal teas on plasma total testosterone in rats. Results showed that testosterone levels actually decreased.

Several more studies have been conducted showing that same link between mint and decreased testosterone. However, most of these studies were performed on animals, so more extensive research on humans is still needed to draw proper conclusions.

flaxseed testosterone

7 – Flaxseeds

It’s sad to say, but you’re going to have to come to grips with the fact that some otherwise healthy foods are not the best choices when it comes to testosterone. You’ve already seen that with soy and now you’re seeing it with flax.

These golden and brown little seeds have for many years been hailed for all their health benefits. And it’s true that they’re high in fiber, have a decent amount of protein, and contain essential fats.

But, much like soy, they also ramp up your estrogen levels, thus suppressing testosterone. This study, for example, tested supplementing women with flaxseed to try and lower their testosterone levels; and it worked…

Regardless if they’re whole seeds, milled seeds, meal, or oil, it’s in your best interests to skip the flax altogether. Replace it with a seed that you know is safe like chia, hemp, or sesame.

nuts testosterone

8 – Nuts

Last but not least, nuts!

“Wait, aren’t nuts supposed to be good for me?!”

Yes, and also no…

Nuts in general are great sources of stuff like fiber, magnesium and folic acid. They are packed with power and they are definitely good to add to a well-balanced diet.

But there is a catch when it comes to testosterone… So if you’re low on T you might want to avoid some of them.

You see, a study found that walnuts and almonds increased sex hormone-binding globulin (SHBG) levels in women. This SHBG binds to testosterone, potentially decreasing your free testosterone levels.

But note that this doesn’t apply to all nuts out there. Take for example Brazil nuts, which actually INCREASE your testosterone levels!

So there you have it, my full list of testosterone killing foods to avoid! You might want to leave these off your shopping list in the future.

Aside from avoiding these foods there are also things you can do to actively boost your testosterone levels.
