Iodized salt is a kind of salt added with iodine, and its benefits include preventing iodine deficiency disorders and promoting thyroid function. For people who need iodine supplementation, such as pregnant women, lactating women and teenagers, it is beneficial to eat iodized salt in moderation. However, it should be noted that excessive intake of any kind of salt may lead to diseases such as hypertension, so the daily intake should be controlled.

As for whether iodized salt is good in snowy days, it needs to be evaluated in combination with specific conditions. On the one hand, iodized salt in snowy days is clean rock salt from a thousand meters deep well, which has no pollution, high purity and guaranteed quality. On the other hand, iodized salt in snowy days does not contain chemical substances such as potassium chloride and ferrous chloride, which is relatively safer and healthier. But for people who don't need extra iodine supplementation, such as normal and healthy adults, eating salt can meet the basic needs of the body without extra iodine supplementation.

In a word, it is beneficial to eat iodized salt in moderation, but we should choose the right salt according to our personal situation. For those who don't need extra iodine, just eat ordinary salt. At the same time, any kind of salt should be taken in moderation, and excessive intake may have adverse effects on the body.
