Lacking iodine in the diet leads to iodine deficiency. This will leads to the production of hyperthyroidism and makes the thyroid gland enlarge which turns into Goiter. There has been substantial progress in reducing the frequency of iodine deficiency. In 2007, data were available from 130 countries covering 92.4 percent of the world's 6 to 12-year population. Approximately 31.5 percent (264 million) of school-aged children (corresponding to an estimated general population of about 2 billion individuals) were iodine deficient (defined by a daily iodine intake <100 mcg). This represented a 5 percent decrease in prevalence in school-aged children since 2003. The largest decreases occurred in South East Asia and in the Western Pacific. Between 2003 and 2013, the total number of countries with adequate iodine intake increased from 67 to 111.
Iodine content in foods is also influenced by iodine-containing compounds used in irrigation, fertilizers, and livestock feed. Iodophors, used for cleaning milking equipment, milk cans and teats in the dairy industry, can increase the native iodine content of dairy products through contamination of iodine-containing residues.
