ertain foods can negatively affect thyroid function and should be limited by those with thyroid tumors.
Causes of Thyroid Cancer
The exact cause of thyroid cancer remains unclear, but risk factors include radiation exposure, iodine deficiency, and genetic mutations. Other contributors include goiter, thyroid inflammation, obesity, and a family history of thyroid disease. Exposure to radioactive materials and previous radiation therapy to the neck can also increase risk.
Foods to Limit
-
Cruciferous Vegetables
Vegetables like cabbage, kale, and bok choy contain goitrogens, which can reduce iodine absorption and lower thyroid function. Cooking them helps reduce this effect. -
Soy Products
Soy contains isoflavones, which may interfere with thyroid hormone production, especially for those on thyroid medication. -
Processed Foods
These contain preservatives and unhealthy fats that hinder thyroid hormone production. -
Caffeine & Alcohol
Caffeine affects medication absorption, while alcohol damages thyroid cells. -
High-Iodine Foods
Excess iodine can disrupt thyroid function, especially during radioactive iodine treatment. -
Hard, Gluten, Spicy & Sour Foods
These can cause digestive discomfort, irritation, and inflammation, particularly post-surgery.
Superfoods for Thyroid Health
Berries, apples, Brazil nuts, avocados, eggs, yogurt, and pumpkin seeds support thyroid function by providing essential nutrients and antioxidants.
