We present the case of a patient with congenital hypothyroidism who remained persistently hypothyroid while on a soy formula diet despite large doses of L-thyroxine (T4). This case made us reaware of the historical data on the effects of soy on thyroid function. It also realerted us to the thoughtful use of formula preparations and close dietary monitoring of hypothyroid infants.}, issn = {0031-4005}, URL = {https://pediatrics.aappublications.org/content/96/1/148}, eprint = {https://pediatrics.aappublications.org/content/96/1/148.full.pdf}, journal = {Pediatrics} }
