EFFECT OF CASEIN ON IODIDE METABOLISM1

Abstract

Dietary purified casein was shown to be an effective goiter preventative agent. No inorganic iodide was found in the casein but a very small amount of organic iodide was demonstrated. Milk proteins were iodinated in the synthesis of milk. It is proposed that the casein-iodine combination, when digested, results in a substance which can prevent thyroid hypertrophy.
