Like most Americans, you probably have a box of salt in your cupboard and think you are getting iodine. Some refined table salt sold in the United States contains iodine so you might think that you are getting iodine or don't need more iodine, but this is not always true. Many forms of salt sold today do not contain iodine. Find out how much iodine is really in that salt shaker, what kind of iodine you are getting, and why the type of iodine matters.
Iodized Salt and the Goiter Belt
When the United States entered World War I, the extent of goiter in the USA was discovered. Upon examination of men joining the military, doctors found the incidence of goiter was as much as 30 percent. The highest occurrences of goiter came in areas of the country, like the upper Midwest, where crop soil was low in iodine (later termed called the “goiter belt”). As a result, the USA began adding iodine to table salt.
Is Iodized Salt Bad for You?
Today, the vast majority of Americans get way too much sodium and in forms that don't contain any iodine. A whole range of health problems, including heart attack, stroke, and high blood pressure are associated with excessive salt intake. Cutting back on salt is good for overall health. Harvard Health recommends cutting back on salt and getting iodine from other sources instead. Furthermore, iodized salt only provides a fraction of the daily iodine intake and in the form of potassium iodide, which is a critical detail to understand.
Another problem with iodized salt is that it contains tons of synthetic chemicals, which are not healthy for the body. Back in the 1920s, salt naturally contained the trace mineral iodine because it came from the sea.
Today, iodized salt is no longer naturally harvested because this method costs more money. It is cheaper to manufacture sodium using processed ingredients. Manufactured sodium contains approximately 97.5 percent sodium chloride, which is an unnatural chemical form of salt. This form of salt is in processed foods. Even worse, various chemicals, such as aluminum, and other toxic ingredients are added to the sodium chloride to absorb moisture.
According to WebMD.com, only about 20% of the salt Americans eat contains iodine(1).
What People Don't Know About Iodized Salt
The iodine used in iodized salt is potassium iodide which is a human-made salt compound unlike molecular iodine which is an essential mineral(2)
