How can goitre be prevented?

Goiter is the result of a dietary deficiency, insufficient iodine, and occurs in areas where the foods that people eat do not contain enough iodine because they do not routinely eat seafood and the soils in which their food is grown lacks iodine that can be taken up by the plants.

Because seafood normally is a rich source of iodine, those populations with access to fish were historically less likely to experience goiter.

Routine consumption of seafood was a very early means of preventing or treating goiter. In more recent decades, the addition of iodine to salt (iodized salt) used on food has prevented goiter in most developed countries.
