However, in an Instagram video shared on February 20, Dr Ali Kazemi, MD (gastroenterology and hepatology), talked about the recent increase in the number of iodine deficiency cases because of the growing popularity of Himalayan salt and sea salt.
Iodine deficiency re-emerging partly because of Himalayan and sea salt
Sharing the video, Dr Kazemi warned that the popularity of Himalayan salt and sea salt over iodised table salt is causing iodine deficiency in people. He wrote, “From a Gastroenterologist: Did you know iodine deficiency, once nearly eradicated, is re-emerging partly due to the popularity of Himalayan salt and sea salt over iodised table salt.”
What are the benefits of consuming iodised salt?
Highlighting the benefits of iodine salt, the gastroenterologist shared that iodine is very important to prevent ‘thyroid diseases and in pregnancy for fetal brain development.’ “To maintain adequate iodine levels, it’s essential to use iodised salt or consume iodine-rich foods such as fish, dairy products, and seaweed,” he added.
According to the World Health Organisation (WHO), a trial involving more than 20,666 individuals from China, Germany, India, Italy, Malaysia, and South Africa found that iodine reduced mortality related to its deficiency disorders, reduced goitre (thyroid size), boosted physical and mental development in children, and lowered the risk of symptoms of hypothyroidism (reproductive failure/infertility, myxoedema, tiredness, lethargy, slowing of mental function, cold intolerance and/or cardiac complications).
Another March 2024 study stated the benefits of iodised salt, including preventing thyroid problems, improving overall health, improving pregnancy outcomes, and improving physical and mental growth.
