Many people have forgotten that iodine is an essential trace mineral and that iodine deficiency was a huge public health issue all throughout human history until 1924 when iodized salt was introduced. Up until 1924, 20% of the population, more in inland populations, had a disfiguring goiter, often dying prematurely. This is because all the iodine on the planet is in the ocean and inland populations were deprived of food and water that contained iodine. Iodized salt was therefore regarded as one of the great public health success stories of the twentieth century.
But some people showed adverse effects of excessive salt consumption (especially those consuming plenty of grains and sugars) and health authorities have advised cutting back on salt, no mention made of alternative means of obtaining iodine. As people cut back on salt use, many are now iodine deficient with hypothyroidism and other health issues.
If you no longer want to rely on iodized salt, but want to restore iodine confidently, what is the best source to do so? It’s simple, but just be aware of some basic issues and you won’t have to give it a second thought.
