10. Licorice
Licorice, derived from the root of the Glycyrrhiza glabra plant, is a popular flavoring agent in candies, beverages, and herbal medicines. It has been used for centuries in traditional medicine to treat various ailments, such as digestive issues, respiratory problems, and skin conditions. However, some research suggests that licorice may have a negative impact on testosterone levels, particularly when consumed in large quantities or in concentrated forms.
The primary active compound in licorice, glycyrrhizin, has been found to affect testosterone levels negatively. Glycyrrhizin can inhibit the enzyme 17β-HSD (17β-hydroxysteroid dehydrogenase), which is responsible for converting androstenedione into testosterone. By suppressing this enzyme’s activity, glycyrrhizin can lead to a decrease in testosterone production and contribute to hormonal imbalances.
Several studies have demonstrated the testosterone-lowering effects of licorice. In one study, healthy male subjects experienced a significant decrease in testosterone levels after consuming licorice root extract for just one week. Another study found that women who consumed licorice experienced a reduction in testosterone levels as well.
It’s essential to note that the negative impact of licorice on testosterone levels is primarily associated with the consumption of concentrated forms, such as supplements or extracts. Moderate consumption of licorice-flavored candies or beverages is unlikely to cause significant hormonal imbalances for most people.
If you are concerned about your testosterone levels or are experiencing symptoms of hormonal imbalances, it’s advisable to monitor your intake of licorice and consult with a healthcare professional for personalized advice. By maintaining a balanced diet and a healthy lifestyle, you can help support hormonal balance and overall well-being.
While licorice has a long history of use in traditional medicine and is a popular flavoring agent, its potential negative impact on testosterone levels makes it essential to consume it in moderation. Focus on a nutritious diet and a balanced lifestyle to maintain healthy testosterone levels and support overall health. (8)
