The thyroid gland plays a vital role in the body’s overall health. It produces hormones that regulate energy use and influence almost all organs. When the thyroid does not function properly, a wide range of symptoms can occur—from persistent fatigue to digestive issues. Diet is one of the factors that can significantly affect thyroid function.
How Does the Thyroid Gland Work?
Located at the front of the neck, covering the trachea, the thyroid gland produces two main hormones: T3 and T4, both of which require iodine for their synthesis. These hormones are key regulators of metabolism and influence:
respiration
heart rate
brain activity
motor functions
sleep
digestion
the functioning of other endocrine glands
A hormonal deficiency can slow down metabolism by up to 40%, leading to lethargy and weight gain, while an excess can accelerate it by 60–100%, which can also cause health problems.
The most common thyroid disorder is hypothyroidism, often associated with Hashimoto’s thyroiditis.
