To the Editor: I believe your last sentence is likely to perpetuate the confusion engendered by your lead-in. The concentration of iodine in 100 gm. of various liquid soy formulas has been reported (Arch. Biochem. 93:15, 1961) as follows:
To my knowledge, goiter has not been reported in infants receiving Soyalac. It seems unlikely that 169μg. is more desirable than 2.36μg. if the method of formula preparation is otherwise satisfactory. Unless you are able to give an actual figure for recommended iodine content, I think your last sentence may suggest to the reader that the more iodine present the better.
