Phytoestrogens and Thyroid Function: What You Need To Know
Phytoestrogens have been gaining increasing attention for their potentially beneficial effects on health, particularly for heart health and for women’s reproductive health. But did you know that phytoestrogens can also affect thyroid function?
What Are Phytoestrogens?
Phytoestrogens are naturally occurring plant estrogens found in many foods such as soy, flaxseeds and certain edible plants. They work similarly to estrogen in your body, and they have been used traditionally in some cultures to treat a variety of conditions, including menopause and fertility issues.
How Do Phytoestrogens Affect Thyroid Function?
Research suggests that phytoestrogens can affect thyroid hormones when consumed in large quantities. Some studies have linked high intake of phytoestrogens to thyroid hormone imbalances. In particular, phytoestrogens may inhibit the production of thyroxine (T4), the main hormone produced by the thyroid gland. In addition, because phytoestrogens can also bind to estrogen receptors, they may interfere with the conversion of thyroxine to triiodothyronine (T3), an active form of thyroid hormone that’s essential for many bodily processes.
What Else Should I Know?
Although there is not yet enough evidence to draw any firm conclusions about the effects of phytoestrogens on the thyroid, some experts recommend avoiding high amounts of phytoestrogens if you have or are at risk of thyroid disease. If you are taking thyroid medication, it is important to talk to your doctor about your dietary choices as some medications may interact with phytoestrogens. Additionally, in some cases, phytoestrogens may interfere with the effects of thyroid medication.
What Else Can I Do To Protect My Thyroid Health?
In addition to avoiding excessive amounts of phytoestrogens, you can take other steps to protect your thyroid health, such as:
- Eating Plenty of Iodine-Rich Foods: Iodine is an essential mineral for the production of thyroid hormones, so it’s important to get enough iodine in your diet. Foods such as salmon, tuna, eggs, sea vegetables, and iodized salt are all good sources.
- Avoiding Unnecessary Stress: Stress is one of the main contributors to thyroid imbalances. Find healthy ways to relax, such as yoga, meditation, or gardening.
- Exercising Regularly: Exercise can help regulate your hormones and improve your overall health, including thyroid health. Aim for at least 30 minutes of moderate activity most days of the week.
- Getting Enough Sleep: Not getting enough quality sleep can impair your body’s ability to regulate your hormones. Aim for 7 to 8 hours of sleep a night.
Final Thoughts
Phytoestrogens are naturally occurring substances found in certain foods that have been linked to various health benefits. However, research suggests that in high amounts, phytoestrogens may interfere with thyroid hormone production, so it is important to be mindful of your intake if you have or are at risk of thyroid disease. To protect your thyroid health, it is important to pay attention to other factors such as lifestyle factors, stress levels, and dietary choices.
If you think you may have a thyroid disorder, it is best to consult a healthcare professional. Your doctor can help you identify and address the underlying causes while keeping your symptoms under control.
