Iodine, Pollution Reduction Vital for Thyroid Health
the MPR take:
Although adequate iodine intake is needed for thyroid hormone production, normal brain development in offspring, and to reduce vulnerability to some environmental pollutants, approximately one-third of pregnant women in the U.S. are marginally deficient. While most pregnant and lactating women take supplements, only 15–20% of these contain any iodine or are below the recommended amount of 150μg. Environmental chemicals like thiocyanate, nitrate, and perchlorate affect the transport of iodine to the cells in the thyroid, making those with existing iodine deficiency more vulnerable to these agents. The American Academy of Pediatrics is recommending that pregnant women and breastfeeding mothers obtain adequate amounts of iodine and avoid excess nitrate in contaminated water and thiocyanate in tobacco smoke.
