For patients with Goiter, the common question asked โis there any food that I should avoid ? โ Listed below are the foods that may affect thyroid function, hence minimal intake is advised.
Goitrogens are naturally-occurring chemicals found in many plant-based foods. Consuming high amounts of these substances on a regular basis may have an impact on your thyroid health, so it's worth understanding how they affect thyroid function and whether or not it makes sense to limit your intake of goitrogenic foods
Foods that contain goitrogens are able to disrupt thyroid function by inhibiting your bodyโs ability to use iodine. More specifically, goitrogens can block the process by which iodine is incorporated into the key thyroid hormones thyroxine (T4) and triiodothyronine (T3).
They also inhibit the actual release of thyroid hormone by your thyroid gland and disrupt the peripheral conversion of the thyroid storage hormone T4 into the active thyroid hormone T3.
In very large quantities, goitrogens can cause a goiter or an enlarged thyroid. They can also act like antithyroid drugs, slowing down your underactive thyroid and potentially causing hypothyroidism.
Goitrogenic foods are rich in vitamins and minerals, and most experts do not recommend that anyoneโincluding patients with thyroid diseaseโavoid eating them.
Here's what you can do to minimize the risk of negative effects:
Cook goitrogenic vegetables: Steaming, cooking, or fermenting can reduce the levels of goitrogens.๏ปฟ If you like fresh spinach or kale in smoothies, try blanching the veggies and then storing them in the freezer for later use.
Increase your iodine and selenium intake: Getting enough iodine and selenium can help reduce the effects of goitrogens; iodine deficiency is a well-known risk factor for thyroid dysfunction. ๏ปฟ Good dietary sources of iodine include seaweedโsuch as kelp, kombu, or noriโand iodized salt. (Less than half a teaspoon of iodized salt covers your daily iodine requirement.) Great sources of selenium include Brazil nuts, fish, meat, sunflower seeds, tofu, baked beans, Portobello mushrooms, whole grain pasta, and cheese.
