Israel Mandates Iodine Fortification in Table Salt to Combat Deficiency

The Israeli Ministry of Health has announced new regulations requiring the fortification of table salt with iodine, a measure adopted by approximately 120 countries worldwide. This decision comes nearly a decade after a significant iodine deficiency was identified in the Israeli population, particularly among children and pregnant women. Iodine is a crucial mineral essential for thyroid function, hormone production, and cognitive and motor development, especially in fetuses, infants, and children. A deficiency can lead to developmental issues, reduced IQ, and, in severe cases, stillbirth or infant mortality. For adults, it can cause thyroid enlargement or hypothyroidism, potentially leading to weight gain and sensitivity to cold.

According to Ministry of Health studies, about 60% of Israeli children and 85% of pregnant women suffer from a significant iodine deficit. This deficiency is attributed to Israel's reliance on desalinated water, which naturally lacks minerals like iodine, and the widespread use of home water filtration systems. While dairy products and eggs contain some iodine, they are insufficient to compensate for the widespread lack, especially for vegans.

Table salt was chosen as the vehicle for fortification because it is a widely accessible product used by all socioeconomic groups, has a limited number of producers making oversight easier, and iodine does not significantly alter its taste. The regulation will apply only to table salt and not to specialty salts or coarse salt. The Ministry stated that the cost of adding iodine is minimal, estimated at about 10 cents per person annually in the US, and is not expected to increase the price of regulated salt.

While iodine is essential, excessive intake can be harmful. However, the controlled addition to salt, used in limited quantities, minimizes the risk of overconsumption. For individuals with existing thyroid conditions, consulting a doctor before regular consumption of iodized salt is recommended. The implementation of these regulations is expected within two years, marking a significant step after over a decade of advocacy by public health experts and researchers who highlighted Israel's lagging position compared to other developed nations.
