Iodine directly affects your thyroid gland secretions, which controls your heart action, nerve response to stimuli, rate of body growth and metabolism.
Every body needs iodine for their thyroid to function normally. If you have an iodine deficiency, your thyroid cannot make a sufficient amount of its hormone. So your body goes into a thyroid deficit, which is a cause for anxiety.
During periods of iodine deficiency, your anterior pituitary secretes its thyroid-stimulating hormone and your thyroid increases in size in a vain attempt to produce more hormones. The result is what’s referred to as a goiter.
Iodine is a trace mineral that is also an essential nutrient for normal cell metabolism. Metabolism is the process of converting food into energy.
Iodine deficiency is rare in the U.S. due to its inclusion is many salt products.
