Extracted from the Wikipedia article Hashimoto's thyroiditis.
High iodine consumption
Autoimmune thyroiditis has a higher prevalence in societies that have a higher intake of iodine in their diet, such as the United States and Japan, and among people who are genetically susceptible. It is the most common cause of hypothyroidism in areas of sufficient iodine. Also, the rate of lymphocytic infiltration increased in areas where the iodine intake was once low, but increased due to iodine supplementation.
