Fish, lodin, Goiter

Much has been said of the giving of small quantities of iodin regularly to growing children in districts where goiter is frequent, and the accumulated scientific evidence seems to show that the method is efficient. Donald K. Tressler and A. W. Wells of the U. S. Bureau of Fisheries have recently made a study of the amount of iodin contained in various food substances. Iodin is found in all fish and fishery products, mollusks and crustaceans; marine fishes contain more iodin than fresh water fishes. Oysters, clams and lobsters contain 200 times as much iodin as beef steak or milk; shrimp 100 times as much; crabs and most ocean fishes 50 times as much. By careful planning of diet in districts where goiter abounds, the giving of iodin in this way may result in efficient prevention.
