Their studies suggested that a goitrogenic agent which interfered with hormonal synthesis in certain susceptible individuals was present in soybeans. Hydovitz8 discussed the appearance of thyroid enlargement in a 4½-month-old male infant maintained on a soybean extract and the subsequent disappearance of the enlargement after the elimination of this nutrient.
