Is Your Thyroid Affecting Your Mood?

    To form sufficient quantities of the thyroid hormone  4 Day Thyroid Diet  thyroxine or T4, about 50 milligrams of iodine in the form of iodides in the diet is required every year. This just shows how important iodine is in the process of thyroid hormone formation and consequently, the regulation of the body's metabolism. Iodides in the Diet The iodides available in your food are absorbed in the gastrointestinal in much the same way as chlorides. These are then normally rid of by the kidneys through the urine but not before the thyroid gland gets its share of iodides. This share constitutes about a fifth of the whole amount of ingested iodide. The first step in thyroid hormone formation is the acquisition of iodide by the thyroid gland by a mechanism known as iodide trapping. The basal membrane of the thyroid cell is specifically designed to pump iodides actively into the cell. In a normal gland, the pump has the ability to concentrate the iodide to 30 times the concentration of iodides in the blood and in a hyperactive gland, this shoots up to about 250 times more. The iodide pump is regulated by several factors but mainly by the concentration of thyroid-stimulating hormone or TSH. TSH is a hormone secreted by the pituitary gland to regulate thyroid gland activity. Aside from increasing the rate of iodide trapping by the pumps, it also stimulates the thyroid gland to produce and secrete more thyroid hormone. When concentrations of thyroid hormone reach desirable levels and normal metabolic rates are achieved, the TSH levels go down until such time the pituitary gland receives a signal to secrete more hormone.
