Goitrogens

Goitrogens are substances that can interfere with the function of the thyroid gland. Their consumption can thus lead to the development of goiter, which is an enlargement of the thyroid gland. Foods high in goitrogens include broccoli, kale, cauliflower, spinach, soy, and some types of fruits and nuts. Although these foods contain goitrogens, they are also rich in vitamins, minerals, and antioxidants that are beneficial to the body. Individuals who do not have thyroid problems do not need to completely eliminate these foods from their diet. However, in cases of hypothyroidism or other thyroid disorders, it is advisable to consult a doctor about their consumption.

Are there goitrogenic substances in buckwheat, please?
Thank you.

Buckwheat does contain goitrogens, but in very small amounts (negligible for metabolism).
