Goitrogens
Goitrogens
Goitrogens (pronounced: goy-tro-jens) are substances that interfere with the function of the thyroid gland by inhibiting the uptake of iodine. The term "goitrogen" is derived from "goitre," which means an enlarged thyroid, and "-gen," meaning producing.
Types of Goitrogens
There are two main types of goitrogens: those that occur naturally in certain foods and those that are man-made.
Natural Goitrogens
Natural goitrogens are found in a variety of foods, particularly in cruciferous vegetables such as broccoli, cabbage, and kale. Other foods that contain goitrogens include soy products, peanuts, and strawberries.
Man-made Goitrogens
Man-made goitrogens are often found in medications and chemicals used in industry. Some examples include lithium, a medication used to treat bipolar disorder, and perchlorate, a chemical used in rocket fuel.
Effects of Goitrogens
Goitrogens can cause an enlargement of the thyroid gland, known as a goitre. This can lead to symptoms such as a swollen neck, difficulty swallowing, and in severe cases, difficulty breathing. Goitrogens can also cause hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones.
Prevention and Treatment
The effects of goitrogens can be mitigated by consuming a diet rich in iodine, which is needed for the production of thyroid hormones. Foods high in iodine include seafood, dairy products, and iodized salt. In some cases, medication may be needed to treat the effects of goitrogens.
