There are actually
four halogens: iodine, bromine, fluorine and chlorine. All these halogens use the same receptors in the body. Therefore if a person’s diet is deficient in iodine the iodine receptors in the thyroid and stomach, for example, may fill up with bromine which is common in grains, bleached flour, sodas, nuts and oils as well as several plant foods. Iodine is depleted by bromine, which is used as a spray on fruits and vegetables, in baked goods, as a fumigant, and in Prozac, Paxil and many other pharmaceutical drugs. Chlorine, fluorine, and fluoride are chemically related to iodine, and compete with it, blocking iodine receptors in the thyroid gland.
Iodine intake immediately increases the excretion of bromide, fluoride, and some heavy metals including mercury and lead. Bromide and fluoride are not removed by any other chelator or detoxifying technique.
Dr. Kenezy Gyula Korhaz states that iodine chelates heavy metals such as mercury, lead, cadmium and aluminum and halogens such as fluoride and bromide, thus decreasing their iodine inhibiting effects especially of the halogens.
Iodine has the highest atomic weight of all the common halogens. [Which makes it the best chelator]
Dr. David Brownstein says that fluoride inhibits the ability of the thyroid gland to concentrate iodine and research has shown that fluoride is much more toxic to the body when there is iodine deficiency present. When iodine is supplemented the excretion rate of the toxic halides bromide, fluoride and perchlorate is greatly enhanced.
Brownstein says that after only one dose of iodine the excretion of fluoride increased by 78% and this is very important for those who are drinking fluoridated water or are taking medicines with fluoride in them; bromide excretion rates increased by 50%. Our environment is loaded with the toxic halides bromine and fluorine and up to now we have had no way to detoxify the body of these thyroid poisons.
Dr. Abraham noted that in some patients the excretion of lead, cadmium and mercury increased several fold
after only one day of iodine supplementation and that increased aluminum excretion was noted about a month after beginning supplementation. Orthoiodosupplementation
[50MG or more daily] induces a detoxification reaction in some patients with high bromide levels.
Dr. Brownstein indicates that iodine is also a chelator of mercury and had tested quite carefully the amounts removed.
