Healthy testosterone levels are essential for keeping active, having a great sex life, and feeling overall healthy. If your testosterone levels drop, you may start experiencing the opposite of these effects.
Often testosterone levels drop because of aging or injury, but your recent deficiency may also be due to your diet.
This article dives into the top 10 foods that kill testosterone production and how you can boost your T levels naturally.
Key Takeaways: Foods That Lower Testosterone
- Testosterone production may be affected by various lifestyle choices, including diet, stress, and sleep quality.
- A balanced diet high in foods containing vitamin D may help in maintaining healthy testosterone levels.
- Trans fats, sugar, and alcohol are some of the foods that kill your testosterone production.
- You can boost your T levels naturally by using dietary supplements or ascorbic acid treatment.
- Low testosterone levels can cause adverse effects in both men and women, including reduced energy and sex drive.
Can Diet Affect Testosterone Levels and Testosterone Production?
Your diet can significantly impact your body’s testosterone production and, subsequently, your overall testosterone levels.
In men, a low-fat diet, or a diet in which most of the fats were unsaturated, lowered both serum and free testosterone levels . However, these effects may vary from person to person. Further research showed that decreasing testosterone due to low-fat dietary choices is more significant in men of European descent .
Bread, pastries, dairy, and processed foods also fall into the category of foods that kill testosterone production and lower testosterone levels .
10 Testosterone Killing Foods
Top 10 testosterone killing foods include:
- Processed foods
- Sweet treats and baked goods
- Licorice root
- Vegetable oils
- Some types of nuts
There is no doubt that your diet and lifestyle choices can affect your body’s testosterone production and T levels. However, some foods may do so much faster than others.
1. Processed Foods
Processed foods that kill testosterone levels include:
- Fried foods, including fried chicken and fish, donuts, fries, and chips 
- Processed meat like sausages and bologna 
- Foods with higher concentrations of trans fats 
- Diet soda containing aspartame 
Processed foods often contain large amounts of sugar and trans fats. These ingredients can cause an increase in your body fat due to a calorie surplus.
High percentages of body fat are directly linked to reduced testosterone levels, especially in men.
2. Sweet Treats and Baked Goods
Sweets and baked goods that could lead to reduced testosterone levels and production include :
- Cakes and cupcakes
- Croissants and other sugary pastries
- White bread
- Desserts like ice cream and other sweet treats
Baked goods, especially white or other processed grain breads, can lead to weight gain and loss of muscle mass . This usually indicates an increase in body fat percentage, which negatively affects your body’s testosterone production and causes your testosterone levels to drop .
Forms of mint that may decrease testosterone levels include :
- Peppermint tea
Regularly consuming products containing spearmint or mint, including sweets and gum, could harm your body’s testosterone production. Peppermint tea can also stimulate the increase in concentrations of follicle-stimulating hormone and luteinizing hormone levels.
4. Licorice Root
Licorice root products that may lower testosterone levels include:
- Licorice root supplements
- Skincare products
- Candy and black licorice sweets
Licorice consumption has been shown to significantly lower testosterone levels in both men and women .
5. Vegetable Oils
Vegetable oils that can lower testosterone levels include:
- Olive oil
- Coconut oil
- Butter spreads
Trans fats are formed when vegetable oils are hydrogenated, like when producing margarine. Consuming large quantities of trans fats could dramatically decrease your body’s ability to produce testosterone and negatively affect your total and free testosterone levels.
Trans fat is one of the most damaging to your cardiovascular system and may cause heart disease if used extensively or in large quantities .
Another study showed that men who consume polyunsaturated fatty acids also experienced a drop in their testosterone levels .
Foods containing large amounts of sugar that could lead to lower free testosterone levels include:
- Sweets and candies
- Sodas and sugary beverages
- Fruit juices
Foods high in glucose and other sugars have a negative effect on your body’s testosterone levels . Reducing your candy and sugar-sweetened beverage intake can help bring this unwanted testosterone-killing effect to an end.
Alcohol consumption may have opposite effects on the testosterone levels of men and women. Drinks that contain alcohol and may affect T levels include:
Acute alcohol intoxication has been shown to increase the levels of the stress hormone cortisol in your body, leading to a reduction in serum testosterone levels in men and a slight increase in women .
Other hormone levels are also affected by alcohol, especially luteinizing hormone in men.

Flaxseed is an ingredient in other foods that lower testosterone levels, including:
- Whole-grain bread
- Energy bars
Although flaxseed has many dietary benefits, the food can decrease total serum testosterone levels in both men and women when consumed regularly .
For more information on the interaction between flaxseed and testosterone, take a look at our article on the topic.
9. Some Types of Nuts
Nuts that could result in reduced free testosterone levels include:
Despite many nuts containing healthy fats and other beneficial nutrients, some nuts may increase the levels of sex hormone-binding globulin (SHBG) which binds to testosterone and can cause a decline in free testosterone levels .
Dairy products that may cause a drop in testosterone levels include:
- Cow’s milk
Several derivatives of cow’s milk may contain natural or synthetic hormones that could interfere with your body’s testosterone production. Many of these animals have a diet heavily reliant on soy, leading to elevated estrogen levels in their milk and negative effects on your total T levels .
Soy and Testosterone: Is Soy Bad for Men?
Many articles claim that consuming any type of soy product or soy milk can have devastating effects on your testosterone levels.
Soybeans and their products typically contain chemicals known as isoflavones or phytoestrogens. Phytoestrogens share similarities with the structure of the estrogen hormone. They have been suspected of affecting androgen receptors and may trigger estrogen receptors to produce a feminizing effect in men consuming soy products.
However, these effects are very weak and will require unthinkable amounts of soy products to be consumed before affecting your body’s testosterone levels .
Studies claiming soy to be harmful are done on mice and rats, not humans. However, the few studies on soy that do involve humans show no change in testosterone, SHBG, or free testosterone levels caused by the food group.
If you’re unconvinced and looking for more information on the question, “Does soy increase estrogen in men?” check out our detailed article.
Which Food Increases Testosterone the Most?
Just as some foods decrease your testosterone levels, certain foods may boost testosterone and your body’s hormone production. These foods may also provide additional health benefits and include:
- Honey: Honey can increase serum testosterone levels in old or young healthy men . High-quality honey also contains many antioxidants, including flavonoids .
- Garlic: Garlic can increase testicular testosterone production . The herb also has antimicrobial and cardiovascular properties .
- Vitamin D is an essential compound required to boost testosterone levels . Foods that are rich in vitamin D include:
- Fish, like tuna, salmon, and sardines
- Milk fortified with vitamin D
- Egg yolks
- Fortified cereals
Overweight and obese men may experience lowered vitamin D levels and therefore reduced testosterone levels.

Low Testosterone: Symptoms, Causes, and Diagnosis
Low testosterone levels can cause various adverse symptoms in men and women.
Symptoms of low testosterone levels in men:
- Decreased libido
- Loss of body and facial hair
- Increased body and belly fat
- Muscle weakness
- Decreased bone density
- Erectile dysfunction
Symptoms of low testosterone levels in women:
- Reduced sexual desire
- Sexual dysfunction
- Decreased bone density

Low Testosterone Diagnosis
Reduced testosterone levels can be detected and diagnosed through a blood test evaluating your total and free testosterone concentrations.
Several measurements may be taken throughout the day to ensure an accurate overall concentration is identified. For each gender, there are specific normal ranges for various age groups. Anything below the normal range may be taken as a testosterone deficiency.
How To Boost Testosterone Naturally
There are many ways of boosting testosterone levels naturally. The two most common avenues include taking dietary supplements or making lifestyle changes, which are discussed below.
T-boosters are a popular way of increasing your testosterone levels, although they are not FDA-approved as they are classified as dietary supplements.

Ascorbic Acid Treatment
Taking regular doses of vitamin C, also known as ascorbic acid, may help increase your body’s serum testosterone levels. Ascorbic acid treatment also enhances sperm quality .
If you’re not interested in taking T boosters or supplements, lifestyle changes can help boost your testosterone levels naturally.
As proven in this article, your diet can significantly affect your body’s testosterone production. Eating healthy foods rich in vitamin D and avoiding processed or sugary foods could help your testosterone levels balance out once more.
Although some forms of exercise may boost testosterone levels more than others, simply just moving your body and elevating your heart rate could be enough to give your testosterone levels a boost .
Stress hormones can cause a drop in your testosterone levels . Reducing your stress levels could help boost your testosterone production.
Losing weight through dietary changes and regular exercise could significantly boost your T levels.
Lower sleep quality can affect your body’s testosterone production. Getting enough good quality sleep could help naturally boost your T levels, too.
Spend Time Outdoors
Spending time in the sun could help your body produce its own vitamin D. Exposing your skin to the sun for a couple of minutes every day could subsequently raise your testosterone levels as well.
Below are some of the most frequently asked questions about the effect of your diet on testosterone levels and production.
What Food Kills Testosterone the Most?
Foods that reduce testosterone production and kill testosterone levels the most include:
- Processed foods
- Licorice root
- Vegetable oils
- Sugary drinks
Do Tomatoes Lower Testosterone?
Yes, tomatoes may temporarily reduce your testosterone levels, although this effect is not significant enough to warrant not eating them .
Do Bananas Lower Testosterone?
No. In fact, an enzyme known as bromelain, found in bananas and pineapples, may help increase your body’s testosterone levels .
Does Masturbation Decrease Testosterone?
There is no scientific evidence that masturbation decreases testosterone levels, although abstinence from the act may increase your T levels marginally.
Diet and other lifestyle factors can play an essential role in increasing or decreasing your body’s testosterone levels. Avoiding the foods that kill testosterone, exercising regularly, and maintaining a low-stress living environment could help boost low testosterone levels and get back your libido and energy levels.
Natural T boosters or medical treatment may do the same, although they should only be seen as a last resort after improving your lifestyle choices.
