These are foods that people with thyroid tumors should limit eating every day.
What causes thyroid ca:nc:er?
Experts are not sure why some cells become ca:ncerous (malignant) and attack your thyroid. Some factors, such as radiation exposure, a diet low in iodine and faulty genes can increase the risk.
Other risk factors include:
– Enlarged thyroid (goiter).
– Family history of thyroid disease or thyroid cancer.
– Thyroiditis (inflammation of your thyroid gland).
– Gene mutations (changes) that cause endocrine diseases, such as multiple endocrine neoplasia type 2A (MEN2A) or type 2B (MEN2B) syndrome.
– Low iodine intake.
– Obesity (high body mass index).
– Radiation therapy for head and neck cancer, especially during childhood.
– Exposure to radioactive fallout from nuclear weapons or a power plant acc-ident.
Doctors advise you to eat less of these foods
1. Cruciferous Vegetables
Cruciferous vegetables such as bok choy, kale, cabbage, etc. contain a lot of goitrogens – compounds that block the absorption of iodine into the thyroid gland and reduce thyroid stimulating hormone (TSH). Excessive consumption, especially when eaten raw, can increase the risk of goiter and thyroid tumors. However, if cooked, the enzymes in the vegetables will be broken down, helping to reduce the amount of goitrogens. Patients can still eat them but should limit them.
2. Products made from Soybean
Soybeans contain particularly high amounts of isoflavones – a substance that can reduce the ability to produce thyroid hormones. Though they are not a completely banned food, you should limit the consumption of soybeans and soy products. For patients who have had thyroid surgery and need to supplement thyroid hormones from medication, the consumption of soybeans needs to be strictly controlled.
3. Processed Foods, Lots of Additives
