The thyroid is a small, butterfly-shaped gland located in front of the trachea. It plays a crucial role in regulating metabolism, heart rate, body temperature, brain development, and more through the release of essential hormones.
When the thyroid isn’t functioning properly, the entire body can be affected. Common thyroid disorders include hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), goiter (enlarged thyroid), and thyroid cancer. While many of these conditions stem from genetics or autoimmune diseases, some thyroid issues can be linked to diet, particularly iodine imbalance.
Certain foods can negatively impact thyroid function. Soy and soy-based products contain isoflavones, which interfere with iodine absorption and reduce the effectiveness of thyroid medications. Cruciferous vegetables like broccoli and kale contain goitrogens, which may also hinder iodine uptake.
People with autoimmune thyroid diseases, such as Hashimoto’s, should avoid gluten due to its potential to trigger inflammation and immune responses. Refined sugar can worsen symptoms of hypothyroidism, such as brain fog and weight gain, and should be limited by everyone.
Processed and high-sodium foods pose another risk. Sodium can elevate blood pressure, which is already a concern for those with hypothyroidism. Additionally, coffee should not be consumed immediately after thyroid medication, as it reduces absorption by up to 60%.
On the positive side, foods like fatty fish, eggs, nuts, seeds, seaweed, and antioxidant-rich fruits support thyroid health.
