The original Morton Salt girl

Though salt is necessary for human life, overconsumption contributes to heart disease and other problems. However, modern table salt addresses a separate health concern: iodine deficiency, which can cause mental retardation and goiter, an enlargement of the thyroid gland. A century ago, goiter was so prevalent around the Great Lakes that the area was considered part of a “goiter belt.” Doctors pushed for adoption of a Swiss tactic of adding iodine to table and cooking salt, and Morton Salt began selling its iodized salt in 1924.
