Pink salt, Himalayan salt or rock salt—popularised by health influencers, these alternatives to the good old table salt have now become a kitchen staple across the world. While these low-sodium alternatives are marketed as "healthier options," they strip off other essential nutrients, like iodine, in the salt too. Following the same, experts have raised serious concerns stating that iodine serves important functions like regulating blood pressure, metabolism and brain development and its deficiency could prove to be detrimental to health. So, Why Do We Need Iodine?This crucial mineral plays a vital role in the production of thyroid hormones, which regulate metabolism and are critical for brain development—especially during pregnancy and early childhood. Iodine is found mostly in animal-based foods like dairy and poultry, making it a nutrient of concern for vegans, who may not get enough from their diet alone. and on top of that, a switch to these iodine-less alternatives of table salt poses the risk of deficiency. The issue triggered headlines when a popular a popular health influencer pointed it out. In a rell, he underscored that iodine deficiency, once widespread in the 1960s, had been successfully tackled after the government mandated the use of iodized salt. This simple public health intervention helped reduce the incidence of goiter and developmental delays associated with iodine deficiency. However, with the return of “fancy” and “traditional” salts like sendha namak—often priced two to five times higher than iodized salt—the trend may be reversing. Besdes that, these salts are frequently marketed as mineral-rich and “pure,” but in reality, the trace minerals they contain are so less in quantitiy that they offer negligible or no real health benefits.Is World Moving Towards Iodine Deficiency?While there is currently no official declaration from Indian health authorities regarding a national iodine deficiency crisis, the growing consumption of non-iodized salts is cause for concern and is exonerating the risk of a probable deficiency in future. Recently, A joint report by the Iodine Global Network (IGN) and the World Health Organization (WHO) stresses that limited awareness among the public and even health professionals continues to be a significant barrier to addressing iodine deficiency. In the US, researchers have increasingly been reporting low levels of iodine in pregnant women and other people, raising concerns about an impact on their newborns. And there is also a very small, but growing, number of reports of iodine deficiency in kids.
