Not everyone needs iodized salt.
Iodine is a very important element for the human body, and iodized salt does prevent many iodine deficiency diseases in iodine-deficient areas.
However, for areas that are not living inland or where you can eat rich foods, the added iodine has caused a serious excess of iodine.
Especially the iodine addition technology that has not been updated in the Chinese salt industry for decades, the potassium iodate is not evenly mixed.
So for people who live near the sea or have symptoms such as hyperthyroidism and thyroid adenoma, it is still healthier to buy iodized salt.
