Israel Mandates Iodine Fortification in Table Salt to Combat Deficiency

The Israeli Ministry of Health will mandate the fortification of table salt with iodine, a measure expected to take effect within approximately two years upon the finalization of regulations. This initiative aims to address a widespread iodine deficiency observed among the Israeli population, particularly impacting children and pregnant women. The fortification will apply to table salt intended for household use, excluding specialty salts or coarse salt. According to the Ministry, the addition of iodine is not anticipated to increase the price of salt, which is largely a price-controlled commodity.

The fortified salt will contain 25 to 45 milligrams of iodine per kilogram. This amount is projected to contribute about 0.045 milligrams of iodine to the daily diet, representing 30% of the recommended daily intake. The Ministry emphasized that this dosage is conservative and will be subject to ongoing monitoring and potential adjustments based on population studies and global data. The decision follows extensive research and consultation with experts, aiming to improve public nutrition without requiring changes in consumption habits, as salt intake is considered consistent.

Surveys conducted in Israel in 2016 and 2021 revealed that 62% of school-aged children and 85% of pregnant women had iodine levels below the World Health Organization's minimum recommendations. Iodine deficiency can lead to cognitive and neurological impairments, increased risk of stillbirth and infant mortality, birth defects, goiter, and hypothyroidism. The Ministry noted that while some iodized salt is already available, it is often sold at a premium. The new regulations will ensure broader access to iodized salt at regulated prices.

Proper storage conditions will be crucial for maintaining the efficacy of iodine in salt. The Ministry advised consumers to store fortified salt in airtight, dry packaging to prevent iodine degradation due to humidity. The fortification effort mirrors similar successful public health initiatives implemented in over 124 countries worldwide, which have historically led to reductions in miscarriages, goiter, and certain types of deafness.

For individuals with high blood pressure, the Ministry stated that the iodine fortification does not constitute a recommendation to increase overall salt consumption. Existing guidelines for limiting salt intake remain in effect to prevent deficiencies without encouraging excessive consumption.
