what about thyroid nodules? What is the cause and what we could try to avoid or diminish them?

Thyroid nodules can be caused by a variety of factors, including iodine deficiency and dietary imbalances. Andrew Huberman mentions that diets lacking in iodine can lead to reduced thyroid function, which may be linked to the development of nodules 1.

To avoid or diminish thyroid nodules, consider the following strategies:

• Adequate Iodine Intake: Ensure that you have sufficient iodine in your diet. Iodine is vital for thyroid hormone production, and deficiencies can lead to thyroid-related issues, possibly including nodules. People on restricted diets (meat-heavy or plant-based) should ensure they are consuming enough iodine by considering supplements or adding iodine-rich foods such as seaweed or iodized salt to their diet 1.

• Balanced Diet: While a clean diet is generally beneficial, it's important to test and adjust your diet to ensure it supports adequate thyroid function. Those consuming a lot of cruciferous vegetables (such as cabbage and broccoli) should be aware that these can interfere with thyroid hormone production and increase iodine needs 1.

• Consider Selenium: Selenium is necessary for the production of thyroid hormones. Most people can benefit from increasing their selenium intake, but it's important to consult with a healthcare provider before making significant dietary changes. Selenium-rich foods include Brazil nuts, fish, pork, and eggs 2.

Monitoring your nutritional intake and consulting with healthcare professionals can help manage and potentially reduce the risk of thyroid nodules.
