At one time Iodine was added to bread and table salt but that is no longer the case. Historically, people living in certain areas — such as the “Goiter Belt” – have less Iodine in the soil and higher rates of Hypothyroidism. Hypothyroidism is still a prevalent problem across the entire USA 3 and around the world.
When thinking about Iodine and it’s importance in the body, we need to consider its relationship to other Halogens. There are four Halogens:
Here is the part that blows my mind. There is a well-known law of halogen displacement, whereby the halogen with a higher weight displaces those at a lower weight. This means, essentially that the higher weight halogen boots out the lower weight halogen. And here is the significance. Fluorine, Chlorine and Bromine all have a higher weight than Iodine.
One might think this is not such a big deal. Until we consider the use of Fluorine (Fluoride), Chlorine and Bromine in our food, water and environment. Up until the 1960s, Iodine was used in bread. In the 1970s this changed, Iodine was removed from bread, and Bromine was used instead! Since bromine and Iodine compete for the same receptors guess what happens to the Iodine? 4.
- In many towns Fluorine (Fluoride) is added to the drinking water
- Chlorine can also be used to treat drinking water 5 and is used in swimming pools 6
- In addition to bread and baked goods, bromine is used many OTC medicines, toothpaste, mouthwashes, flame retardants, and some cosmetics
This all sounds scary, a bit. But it certainly explains why Iodine supplementation can be so important. With Iodine deficiency already present, supplemental Iodine may be needed to compete with the other halogens.
