Although breast-feeding women in the U.S. overall met WHO-recommended iodine levels for lactating women, environmental perchlorate and thiocyanate exposure may counteract iodine nutrition, according to researchers.
“This study provides further understanding of the state of iodine nutrition in U.S.-lactating women,” Sun Y. Lee, MD, of the section of endocrinology, diabetes and nutrition at Boston University School of Medicine, told Endocrine Today. “Breast-feeding women should ensure that they have adequate iodine intake in order to provide adequate iodine nutrition to their breast-fed infant, given the ubiquitous exposure to low-level perchlorate and thiocyanate. In fact, the American Thyroid Association recommends that breast-feeding women take a supplement containing 150 µg/L of iodine per daily dose to ensure adequate iodine nutrition.”
