Testosterone is what separates the men from the boys… literally.

This sex hormone is naturally produced by the body and plays a big role in the development of male characteristics, although, women produce it too, just in smaller amounts (we’ll talk more about testosterone in a minute). And low testosterone, especially in men, is associated with chronic health issues and even premature death.

Now you’re probably wondering what are 8 foods that kill testosterone (since that is the title of this article). But we want to make one thing clear, there likely isn’t a single food that will “kill” testosterone levels. However, it’s a no-brainer that a low-quality diet will affect health, and therefore lower test levels.

Although, there are some foods that may not be the worst, but that studies have shown to be associated with lower testosterone levels. 

So, we’ve provided those studies below, but take them with a grain of salt regarding the extent to which they show certain foods to negatively affect test levels. Moderation is usually key as with a lot of things and we realize that. We also suggest getting your test levels checked if you suspect that you have low levels, then possibly change/improve your diet if you believe your nutritional habits may not be as healthy and balanced as it could be.

Alright, let’s get into these foods that kill testosterone (potentially).

Refined sugars/highly-processed foods

Junk FoodJunk Food

There’s no debate here. Delectable treats, sugar drinks, junk foods, fast foods, highly-processed low-quality meats, and anything in between tend to make up a concerning portion of the typical American diet.

These foods are loaded with calories, simple sugars, saturated fat, sodium, and low-quality protein that, when consumed in excessive amounts over a prolonged period, are not conducive to good health. 

It’s well known that consuming a lot of refined carbohydrates and saturated fats is associated with obesity, Type 2 diabetes/reduced insulin sensitivity, high cholesterol/blood pressure, and other common health concerns. But having chronic health issues tends to throw the body out of homeostasis and so it’s easy to see how testosterone levels are affected.

In fact, one scientific review from 2018 found that individuals who prefer Western-style foods and eat out a lot are more likely to have more visceral fat, less muscle mass, low serum total T levels, and a higher chance of developing hypogonadism (lack of testosterone production).

While it’s not necessarily a sin to have dessert, pizza, ice cream, and all of the mouth-watering options that have become a part of our daily or weekly diet, these foods are likely to contribute to lower test and over time, bad health. 

Alcohol

Alcohol

Who doesn’t like to enjoy an alcoholic beverage every now and then? Well, it’s likely not an issue unless you’re consuming it on a regular basis. And actually, moderate wine consumption, more specifically red wine, can be beneficial for your health. Research has shown that wine can provide disease-fighting antioxidants (polyphenols) that can reduce oxidative stress and inflammation, causes of death.

But it can even widen blood vessels, therefore, improving high blood pressure, cholesterol (also increases HDL cholesterol), and preventing heart disease. Plus, it has shown to have beneficial properties for supporting health overall. 

However, too much alcohol is a bad thing and one of the top causes of mortality in the world. Overconsumption over a prolonged period can negatively overall health that will consequently affect hormone levels.

According to health.gov, women can safely have up to one drink per day while men can safely have up to two drinks per day. But it really depends on the type of alcoholic beverage since they do vary in alcohol content. So, you’ll want to check health.gov or any authority link to determine an appropriate amount for you.

Now as far as alcohol’s effects on testosterone, research is mixed. So much so in fact, that according to one study, acute alcoholic intoxication was shown to increase testosterone in women, and decrease levels in men. And this seems to be the case in other studies as well, implying that gender and sexual maturity could be a factor.

But more studies need to be carried out to better investigate the relationship between varying alcoholic doses and lowered testosterone levels. 

Soy

Soy Foods

While studies in humans are limited, the possibility of soy lowering testosterone levels has always been a concern. 

Common soy food products include soy, tempeh, soy milk, soy protein drinks. These foods are known to contain phytoestrogens that have been associated with having estrogenic effects in the body, therefore causing reduced testosterone levels in men especially .

In one study of thirty-five men, individuals who consumed both low and high-isoflavone soy isolate protein for 57 days experienced

decreased DHT and DHT/testosterone with minor effects on other hormones.

However, in contrast, one review of studies determined no negative effects on testosterone levels in men.

Therefore, more studies are needed for conclusive evidence on the potential effects of soy on testosterone levels. But it’s important to note that some research has suggested that soy could potentially have less than desirable effects in the body without altering hormones and that they’ll go away when you stop consuming it. 

If you suspect that soy is having certain effects on your body, you might want to switch to something else or get medical advice.

But if it’s working for you, there’s no need to stop eating soy, especially since it has a big role in the typical vegan diet.

Vegetable oils

Vegetable Oils

Not all foods with the name “vegetable” are good for you apparently. Vegetable oils such as canola, peanut, corn, and soybean could contribute to lower testosterone. But it’s important to note that these oils contain polyunsaturated fats that are liquid at room temperature unlike saturated fats, and are typically deemed good for heart, brain, and other improvements in health.

However, like several of the options on our list of foods that kill testosterone (potentially), healthy doesn’t necessarily mean a certain food won’t mess with testosterone levels. 

In some studies, consuming polyunsaturated fats on a frequent basis resulted in decreased testosterone levels. Although, more studies are needed to come to a better conclusion on the potentially negative effects of polyunsaturated fats where it relates to T levels due to relatively smaller sample sizes tested.

We should also mention that because oil is high-calorie by nature, consuming too much of it could contribute to weight/fat gain that compromises fat in itself. Moderation is key once again

Nuts

Almonds And Walnuts

Nuts also contain polyunsaturated fats like vegetable oils, and although several varieties contain beneficial nutrients, consuming certain nuts in higher amounts can increase levels of sex hormone-binding globulin (SHBG), a protein that binds to testosterone. That may sound like a good thing but SHBG is linked to lower free testosterone levels.

Almonds and walnuts may be culprits but there needs to be more research to learn which nuts may have the most negative effects on testosterone levels. 

Flaxseeds

Flaxseeds

Flaxseed is a nutritional food that provides good fats (Omega-3’s), fiber, that supports good digestion, and nutrients to support overall good health. Not to mention, it contains lignans that may help to reduce cancer and other health factors.

But you know the drill… it has been associated with a decrease in testosterone levels. 

And actually, both lignans and Omega-3 fatty acids contained in flaxseed may cause a reduction in T levels. Lignans cause testosterone excretion after binding to it in the body and in a study of 78 women with PCOS (Polycystic Ovarian Syndrome), who took 3g/d Omega-3’s for eight weeks, testosterone concentration was significantly lower.

There’s also a study where men with prostate cancer experienced a significant reduction in serum and total testosterone levels after taking 30g/day of flaxseed and eating a lower-fat diet.

There are a few other studies that saw similar results. 

Mint

Mint

Mint?… We’re not saying you have to throw your dinner mints and gum in the trash if you want gains. 

But according to research, mint may be one of those foods that kill testosterone. 

A study found that “high levels” of spearmint has an adverse effect on fertility in adult male rats, not to mention, there are a few studies on rats that found the same effects.

Another study found involving 42 women with PCOS found that the group who drank spearmint tea over 30 days experienced a significant reduction in testosterone.

There’s isn’t much research in men but these are interesting studies.

Licorice root

Licorice Root

Licorice root is used in food products such as candies, tobacco products, and other food items. Today it’s used to treat a variety of ailments such as digestive issues, menopause, and viral infections. 

One study showed a 26% decrease in mean testosterone in 25 healthy adult men in just a week after consuming 7g/d. And there was a similar result in a study of women who took 3.5g/d and saw a decrease of 32% following a menstrual cycle.

Conclusion

Hopefully our list gave you some insight into nutritional choices that may be worth limiting. There are some interesting studies that have found negative associations between some foods and lower testosterone levels. But we’ll admit that for many of these foods, there needs to be more research to come to any definitive conclusions. 

Our best piece of advice is to use your best judgment, keep track of your nutritional choices, and if you’re concerned about your testosterone levels, have them checked.
