Israel Moves to Fortify Table Salt with Iodine Amid Widespread Deficiency

The Israeli Ministry of Health is initiating a new policy to add iodine to table salt, aiming to combat a significant deficiency found in approximately 60% of children and 85% of pregnant women across the country. This deficiency poses risks to cognitive development, growth, and thyroid function.

The initiative follows years of data indicating a persistent lack of iodine, despite Israel's coastal location. Surveys conducted in 2016 and national monitoring data from 2020-2021 revealed no substantial improvement in iodine levels over a five-year period. Iodine is crucial for thyroid hormone production, essential for brain development in fetuses and infants, as well as overall metabolism and growth.

While the move to iodize salt is a common public health strategy employed in over 120 countries, the Israeli plan faces a challenge: only about 15% of the population's salt intake comes from salt added at home or during cooking. The majority of salt consumption, roughly 85%, is derived from processed and industrial foods, which are not included in the initial phase of the regulation.

The Ministry of Health explains that table salt is a widely purchased product, making it an accessible vehicle for iodine supplementation. The planned fortification will add approximately 45 micrograms of iodine per day to the diet, representing about 30% of the daily recommended intake. The ministry emphasizes that this is a conservative dosage and will be monitored, with the goal of replacing regular salt with iodized salt rather than increasing overall salt consumption.

Despite the known deficiency for at least a decade, the regulatory action is only now being advanced. The Ministry states that current data necessitates systemic intervention to reduce deficiency rates, prevent long-term damage, and improve public health. A key question remains whether fortifying household salt alone will be sufficient, or if further measures targeting salt in processed foods will be required.
