Israel Mandates Iodine Fortification in Table Salt to Combat Deficiency

Israel's Ministry of Health will mandate the addition of iodine to table salt, a move aimed at addressing significant iodine deficiencies observed in the population, particularly among children and pregnant women. New regulations will apply to household table salt, excluding salt used in the food industry. This initiative follows data indicating that approximately 60% of children and 85% of pregnant women in Israel suffer from iodine deficiency.

The Ministry emphasizes that the goal is not to encourage salt consumption but to replace regular salt with iodized salt without increasing intake. Table salt accounts for up to 90% of household salt purchases in Israel, yet less than 15% of daily salt consumption, with most coming from processed foods. The ministry aims to ensure adequate iodine supply and reduce deficiency-related health issues.

Iodine fortification of salt is recognized globally as an effective and safe method for combating iodine deficiency, implemented in over 120 countries. It leverages a widely consumed staple to improve population-wide nutrition without requiring significant dietary changes. Iodine is crucial for thyroid hormone production, impacting growth, development, and metabolism. Deficiency can lead to cognitive and neurological impairments, thyroid dysfunction, and increased risks during pregnancy, including stillbirth and infant mortality.

Contrary to a previous assumption that proximity to the sea would ensure sufficient iodine intake, the Ministry notes that Israel's diet is not sufficiently based on iodine-rich seafood, and much of its food supply is imported. Additionally, the widespread use of desalinated water, which has very low iodine levels, contributes to the deficiency.

The fortification will be applied at a level of 30 milligrams of iodine per kilogram of salt, expected to provide about 30% of the recommended daily intake. This dosage is considered conservative and will be monitored, with potential adjustments based on future data. The Ministry anticipates no risk of exceeding recommended iodine intake limits, even for high consumers, and plans ongoing monitoring to assess the program's effectiveness.
