Shaky Amount of Iodine in U.S. Salt
Some 'Iodine-Fortified' Table Salt Falls Short of Recommended Levels of the Nutrient, Study Shows
Feb. 1, 2008 – There are fewer food sources of iodine in the American diet than there were just a few decades ago, raising the risk of iodine deficiency in a growing number of people. So says a researcher who calls himself an "iodine activist."
Even people who buy and use iodine-fortified table salt may be at risk, says Purnendu K. Dasgupta, PhD, a chemistry professor at the University of Texas at Arlington.
Dasgupta and colleagues recently tested 88 samples of iodized salt and found that 47 of them, or 53%, did not meet the U.S. Food and Drug Administration's recommendations for iodine levels.
Iodine levels tended to decrease in individual containers with exposure to humidity, but light and heat had little effect.
The findings are published in the latest online issue of the American Chemical Society journal Environmental Science and Technology.
