For years, the EPA has attempted to ratchet up regulations on any number of so-called “pollutants” without good scientific reason. Such appears to be the case again, according to the Canada Free Press, concerning the chemicals perchlorate and chromium. Perchlorate can indeed interfere with iodine absorption in the thyroid gland, but the natural perchlorate in one serving of spinach can inhibit iodine absorption 300 times more than the perchlorate you’d get drinking two quarts of groundwater. As for chromium, foods like oysters, peanuts, and grape juice naturally contain more than 300 parts per billion, meaning the EPA’s penchant for costly and unnecessary regulations seem to be continuing unabated.
