    How Adding Iodine To Salt Resulted In A Decade´s Worth Of IQ Gains For The United States

    Iodized salt is so ubiquitous that we barely notice it. Few people know why it even exists. Iodine deficiency remains the world's leading cause of preventable mental retardation. According to a new study, its introduction in America in 1924 had an effect so profound that it raised the country's IQ.

    A new NBER working paper from James Feyrer, Dimitra Politi, and David N. Weil finds that the population in iodine-deficient areas saw IQs rise by a full standard deviation, which is 15 points, after iodized salt was introduced.

    Since one quarter of the population lived in those areas, that corresponds to a 3.5 point increase nationwide. We've seen IQs go up by about 3 points every decade, something called the Flynn effect, so iodization of salt may be responsible for a full decade's worth of increasing IQ in the U.S.

    If a mother is iodine deficient while she's pregnant, the cognitive development of the fetus is impeded, and the effects are irreversible. To this day, the World Health Organization estimates that nearly 50 million people suffer some kind of mental impairment related to iodine deficiency.

    Before iodized salt, people were deficient based almost entirely on geography, whether the water and soil in their area had enough of the micronutrient. Diseases resulting from the deficiency, most commonly goiter, or swelling of the thyroid, were extremely common.

    Of course the gain from iodized salt was effectively countered by fluoridated water, govt education and further indoctrination from a pop culture oriented leftist media both in the news and entertainment industrys.

    Too bad we cant ship more iodine to the RINOS in Congress.

    In a related story, adding liberalism to our national media resulted in three decade's worth of IQ losses.

    That's got to be a kick in the teeth to the natural food people and their sea salt preferences.

    My mom always used Morton's salt. One of their mines is located underneath the city of Detroit, by the Ambassador Bridge and by all the refineries.

    That's enough reason to not use Morton's salt.

    I have to wonder if this academic studied in a vacuum. We know that the biggest consumers of salt also produce the greatest number of children we suspect of being intellectually limited. So either these people would be even less intelligent absent their fast food and snack consumption, or the study is flawed.
