Modern life seems to be causing havoc on both men’s testosterone levels and sperm counts.

In fact, studies in recent years have shown that the average testosterone levels in men have fallen by 20% to 40% since 1960, and sperm counts have fallen by 50% in the last 50 years, which are certainly worrying numbers.

Our modern lifestyles and increasing amount of screen time are certainly part of the problem, but our diets and the foods we consume are also to blame. In this post, we’ll explore the foods, drinks and diets you should avoid if you want to maintain healthy T levels.

Alcohol

In one study, healthy male participants showed a decrease in testosterone levels within 30 minutes of a heavy dose of alcohol. Chronic alcohol consumption, especially heavy drinking, can lead to a substantial decrease in testosterone production. It can also impair liver function, which affects hormone metabolism.

Sugary Drinks

These can include soft drinks, fruit juices with added sugars, and sports drinks that are processed and high in added sugars and artificial ingredients.

Multiple studies have revealed that sugar intake hinders testosterone production in men. Consumption of sugary beverages can also contribute to weight gain, obesity, and insulin resistance, which are all factors that will also decrease a man’s testosterone levels.

Processed Foods

Highly processed and packaged foods often contain unhealthy trans fats, which can increase inflammation and may negatively impact testosterone production. These can include:

1. Canned Soups: Canned soups often contain processed ingredients, preservatives, and high levels of sodium. They can include chicken noodle soup, tomato soup, and vegetable soup.
2. Breakfast Cereals: Many breakfast cereals are highly processed and may contain added sugars and artificial flavors. Examples include sugary cereals like Froot Loops and Cocoa Puffs.
3. Frozen Dinners: Frozen dinners and meals are convenient but can be highly processed and contain preservatives. Examples include frozen pizza, microwaveable burritos, and TV dinners.
4. Packaged Snack Foods: These include chips, crackers, pretzels, and cookies. They often contain unhealthy trans fats, artificial flavors, and added salt or sugar.
5. Instant Ramen Noodles: Instant ramen noodles are processed and usually high in sodium. They often come with seasoning packets containing artificial flavors.
6. Packaged Deli Meats: Pre-packaged deli meats, like bologna and salami, are processed and can contain added preservatives and sodium.
7. Bottled Salad Dressings: Many salad dressings in bottles are processed and may contain added sugars, artificial colors, and preservatives.
8. Frozen Desserts: Ice cream, frozen yogurt, and frozen pies often contain high levels of added sugar, artificial flavors, and stabilizers.
9. Instant Mashed Potatoes: These often contain dehydrated potato flakes and various additives to enhance flavor and texture.
10. Canned Vegetables: Canned vegetables, such as corn and green beans, are processed and may contain added salt or preservatives.
11. Instant Pudding Mixes: These mixes contain processed ingredients to achieve the desired texture and flavor.
12. Packaged Instant Oatmeal: Flavored instant oatmeal packets often contain added sugars and artificial flavorings.
13. Packaged Sauces and Gravies: Some sauces and gravy mixes come in packages and can contain artificial flavors and preservatives.
14. Instant Macaroni and Cheese: These often contain powdered cheese and additives for flavor and texture.

Soy

Soy contains compounds called phytoestrogens, which are plant-based compounds that can mimic the hormone estrogen (the female hormone) in the body and affect testosterone production. Soy has been a topic of debate in the last few decades, with some studies showing correlation between soy consumption and a decrease in testosterone, while others didn’t find any correlation at all. If you want to be on the safe side, it’s best to limit your soy consumption or avoid it altogether.

Flaxseeds

Flaxseeds also contain phytoestrogens, similar to soy. Consuming flaxseeds in moderation is unlikely to have a significant impact on testosterone levels, but excessive intake should be avoided.

Licorice

Licorice root contains a compound called glycyrrhizin, which can lower testosterone levels when consumed in large amounts. Here’s how licorice consumption may influence testosterone levels:

1. Anti-Androgenic Effect: Glycyrrhizin has been shown to have anti-androgenic properties. This means that it can reduce the effects of androgens, which include hormones like testosterone. Specifically, glycyrrhizin inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which is involved in regulating cortisol and other steroid hormones, including testosterone.
2. Lower Testosterone Production: By inhibiting 11β-HSD2, glycyrrhizin can lead to an increase in cortisol levels and a decrease in the availability of testosterone. Elevated cortisol levels can negatively impact the production and action of testosterone in the body.
3. Hormone Imbalance: Prolonged or excessive consumption of licorice or licorice-containing products can disrupt hormonal balance in the body. This hormonal imbalance can lead to symptoms such as reduced libido, fatigue, and muscle weakness.
4. Gynecomastia: In some cases, licorice consumption has been associated with gynecomastia, which is the enlargement of breast tissue in men. Gynecomastia can be caused by hormonal imbalances, including changes in estrogen and testosterone levels.

Mint and Peppermint

Some studies suggest that mint and peppermint may have a mild anti-androgenic effect, potentially lowering testosterone levels when consumed in large quantities.

High-Dose Caffeine

While moderate caffeine consumption is generally considered safe for most people, excessive caffeine intake or chronic high-dose consumption can potentially have an impact on hormone levels, including testosterone, through several mechanisms:

1. Cortisol Production: Caffeine can stimulate the release of the stress hormone cortisol. Elevated cortisol levels, especially due to chronic stress or excessive caffeine intake, can indirectly affect testosterone levels. High cortisol levels can interfere with the production and function of testosterone.
2. Disruption of Sleep: Caffeine is known for its stimulant effects, which can interfere with sleep if consumed too close to bedtime or in excessive amounts. Inadequate or disrupted sleep patterns can negatively impact testosterone production, as testosterone is primarily released during deep sleep.
3. Adrenal Gland Function: Chronic high caffeine intake may lead to overstimulation of the adrenal glands, which produce cortisol. Over time, this can contribute to imbalances in the hormonal system, potentially affecting testosterone levels.
4. Metabolic Effects: Caffeine can influence insulin sensitivity and glucose metabolism. In some cases, it may lead to insulin resistance or blood sugar fluctuations, which can indirectly impact hormone balance, including testosterone levels.

Low-Fat Diets

Extremely low-fat diets can potentially reduce testosterone levels because dietary fat is essential for hormone production. A well-balanced diet with healthy fats is important. The body uses cholesterol to create testosterone.

Excessive Caloric Restriction

Severe caloric restriction and very low-calorie diets can lead to a decrease in testosterone levels as the body tries to conserve energy. Here’s how excessive caloric restriction may affect testosterone levels:

1. Energy Deficiency: Caloric restriction to the point of energy deficiency can signal to the body that it is in a state of scarcity or famine. In response to this perceived energy crisis, the body may prioritize conserving energy and shifting resources away from processes that are not essential for immediate survival, including reproduction and hormone production.
2. Reduction in Fat Mass: Extreme caloric restriction often results in rapid weight loss, which can lead to a decrease in body fat. While losing excess body fat can have health benefits, it’s important to recognize that fat tissue plays a role in hormone production, including the conversion of androgens (such as testosterone) to estrogens. A significant reduction in body fat can disrupt this hormonal balance.
3. Impact on Hormone Signals: Prolonged caloric restriction can lead to changes in hormonal signaling within the body. This may include reduced production of hormones that stimulate the testes to produce testosterone, such as luteinizing hormone (LH).
4. Stress Response: Excessive caloric restriction can be a form of physical stress on the body. Chronic stress can lead to an increase in cortisol production, a stress hormone. Elevated cortisol levels can negatively impact the production and action of testosterone.
5. Amenorrhea in Women: In women, excessive caloric restriction can lead to amenorrhea, the absence of menstruation. Amenorrhea is often associated with hormonal imbalances, including reduced estrogen levels. While this pertains to female hormones, it can indirectly affect the hormonal environment in men as well.

Chronic Dieting and Weight Loss

Constantly cycling through extreme diets and weight loss regimens can negatively impact hormonal balance, including testosterone levels. Also, keep in mind that the body needs Cholesterol to produce Testosterone, and Chronic Dieting can lead to Cholesterol levels that are too low.

Lack of Nutrient-Rich Foods

A diet deficient in essential vitamins and minerals, such as zinc and vitamin D, can impair testosterone production. Ensure your diet includes foods rich in these nutrients.

It’s essential to maintain a balanced and varied diet that includes a wide range of nutrient-dense foods, exercise regularly, manage stress, and get adequate sleep to support overall health and hormonal balance. If you have concerns about your testosterone levels or the impact of your diet on your hormonal health, it’s advisable to consult a healthcare provider or a registered dietitian for personalized guidance and recommendations.
