Iodine and Selenium
Iodine (and Selenium)
Iodine is not only important for the thyroid gland. Among others, the brain, ovaries, women’s breasts and testicles use more iodine than the thyroid gland, provided that the iodine reserves of the organism are sufficient, in ideal case that is. It is said that many physicians still consider iodine only in connection with the thyroid gland, and often recommend to fully avoid iodine (even food with iodine content) to their patients with thyroid gland issues or to patients, whose thyroid gland has been removed. The reason many physicians make this recommendation because certain analysis suggests that iodine supplementation and/or high iodine intake might increase the risk of thyroid gland problems, or in case of those suffering from autoimmune thyroid gland disease - not often though - iodine supplementation may temporarily result in slight deterioration of the test results. Other examinations found just the opposite. i.e. that high iodine intake does not increase, but actually and explicitly decreases the risk of thyroid gland diseases, and that additional iodine intake did not deteriorate the values of patients with autoimmune thyroid gland disease, either. So the analyses in the field of iodine supplementation are contradictory. There is full consensus, however, that adequate intake of selenium does reduce the risk of thyroid gland diseases, improves the existing thyroid gland problems, and protects from a potential adverse effect of iodine. The analyses summarily suggest that if there is no lack of selenium, then iodine is not harmful, but is useful. Iodine level of the thyroid gland of patients suffering from autoimmune thyroid gland disease is always a lot lower than the iodine level of the thyroid gland of healthy people. And the worse of one’s condition is, the lower the iodine content of the thyroid gland would be. Iodine intake of Japanese people - who consume the most iodine in the world - is well above 1,000 mcg per day (typically between 1,200 and 13,000 mcg, but higher volumes aren’t rare, either). Still, many diseases of the thyroid gland are rarer in their case, and even the Hashimoto is not more frequent. In turn, their selenium intake is also high.
