- 1. The thyroid enlargement obtained with rations containing 10 and 30% of raw or heated soybeans was effectively prevented with 1 to 2 µg of iodine per rat per day. The iodine requirement of rats was slightly greater on soybean-containing rations than on the basal ration employed.
- 2. The reduced thyroid enlargement resulting from heat treatment indicates that the goitrogenic property of soybeans is partially heat labile.
- 3. Since small amounts of iodine effectively correct the mild goitrogenic property of soybeans, no harmful effects should result from the use of soybeans in practical rations.
