Chronic iodine deficiencies in diet can result in malfunctions of the thyroid gland, the gland that produces hormones necessary for normal human development. Some mountainous regions, such as parts of the Alps, do not naturally provide their inhabitants with a diet rich enough in iodine, and the resultant hypothyroidism causes stunted growth and mental retardation. In Franco-Provençal (the Romance speech of French Switzerland and adjacent areas of France), a person affected by hypothyroidism was called a cretin, literally, “wretch, innocent victim.” The word meant simply “Christian” and emphasized the hypothyroid victim's basic humanity.
