Testosterone plays an essential role in both men and women, supporting functions such as muscle development, bone strength, reproductive health, and mood regulation. While the body naturally regulates hormone levels, health experts note that certain dietary choices may influence testosterone balance over time.
Research into the relationship between nutrition and hormone health continues to evolve, with studies suggesting that some commonly consumed foods and ingredients may be associated with lower testosterone levels when eaten in excess.
Soy-Based Foods
Soy products such as tofu, soy milk, edamame, and miso are widely consumed as plant-based protein sources. However, they contain phytoestrogens plant compounds that can mimic estrogen activity in the body.
Some studies have observed changes in hormone levels following high intake of soy protein isolates, while other research has found little or no significant effect from moderate consumption of whole soy foods. Experts say further studies are needed to fully understand soy’s impact on testosterone.
Mint and Herbal Teas
Mint varieties, including spearmint and peppermint, have been studied for their potential hormonal effects. Some small-scale research suggests that regular consumption may be associated with reduced testosterone levels, particularly in certain populations.
However, scientists caution that most available evidence is limited and more comprehensive human studies are required before drawing firm conclusions.
Licorice Root
Licorice root, often used in herbal remedies and traditional medicine, has been linked in some studies to reductions in testosterone levels. Research involving controlled intake has shown measurable hormonal changes in both men and women.
Health professionals emphasize that this effect applies specifically to concentrated licorice root and not most commercial candies or flavored products.
Certain Vegetable and Processed Oils
Common cooking oils such as soybean, corn, canola, and cottonseed oil contain polyunsaturated fats. Some studies have explored possible associations between high intake of these fats and reduced testosterone levels.
In addition, processed foods containing trans fats have been linked in research to lower testosterone levels and reduced sperm quality in men. Health experts continue to recommend limiting ultra-processed foods for overall metabolic health.
Flaxseed
Flaxseed is widely regarded as a nutrient-rich food due to its fiber and omega-3 content. However, it also contains lignans, plant compounds that may influence hormone metabolism.
Some small studies have suggested that flaxseed supplementation may be associated with reduced testosterone levels in specific medical conditions. Researchers note that broader studies are still needed to confirm these findings in the general population.
Alcohol Consumption
Alcohol intake has long been studied in relation to hormone health. Research suggests that moderate to heavy alcohol consumption may be associated with reductions in testosterone levels, particularly when consumed regularly over time.
Experts note that the effects of alcohol on hormones can vary depending on quantity, frequency, and individual health factors.
Nuts and Hormone Binding Proteins
Nuts such as almonds and walnuts are highly nutritious and widely recommended in balanced diets. However, some research indicates they may influence levels of sex hormone-binding globulin (SHBG), a protein that can reduce the amount of active testosterone circulating in the body.
Scientists emphasize that these findings are preliminary and should be interpreted within the context of overall dietary patterns.
The Importance of Overall Diet and Lifestyle
Health professionals stress that no single food is solely responsible for lowering testosterone levels. Instead, hormone balance is influenced by overall dietary patterns, lifestyle habits, sleep quality, physical activity, and stress levels.
Experts recommend a balanced approach that includes whole foods, regular exercise, adequate rest, and moderation in the consumption of processed products and alcohol to support long-term hormonal health.
