low-iodine diet, according to a new study being presented on Saturday,

(ATA) in New York.

Thyroid hormone is critical for the neurodevelopment of a fetus - 
particularly in the first trimester of pregnancy - and requires the 
mother to receive an adequate intake of iodine.

These findings are in contrast to last year's report from the Center For 
Disease Control and Prevention (CDC), which reported that perchlorate 
exposure, (assessed by the small amount of perchlorate found in the
