What's the difference between Morton's non-iodized salt and iodine-free sea salt?

Morton non-iodized salt is a kind of iodine-free sea salt. Non-iodized salt and iodine-free sea salt are basically the same, but there are some differences between iodized salt and non-iodized salt:

First, the iodine content is different.

Iodized salt refers to salt containing potassium iodate and sodium chloride. Because most areas of our country are short of iodine, iodine deficiency will cause iodine deficiency disease, so the state forces a small amount of iodized salt to be added to edible sodium chloride salt. Non-iodized salt is an edible salt without iodine, which is different from the common iodized salt in China market.

Second, it is suitable for different people.

Except iodized salt, patients with hyperthyroidism, thyroiditis and thyroid tumor do not need to take iodized salt, which is suitable for the general population. Non-iodized salt is an edible salt without iodine, which is different from the common iodized salt in China market. Suitable for people in iodine deficiency areas. Supermarkets and shops don't sell non-iodized salt, but salt companies can buy non-iodized salt.

Extended data:

The average daily salt intake of urban residents in China is 1 1g, and that of rural residents is 10g. This means that most iodized salt in the market contains 20-50 micrograms of iodine per gram, and the daily iodine intake of China people has reached an astonishing 220-850 micrograms, far exceeding the "safety line" of 200 micrograms per day designated by the World Health Organization.

Excessive iodine can lead to goiter and hyperthyroidism, but the etiology of thyroid diseases is complex, which is related to environment, diet, mood and other factors, and iodine intake is only one of them. Two-thirds of iodine in the human body exists in the thyroid gland, and iodine deficiency or iodine excess will lead to thyroid problems, so the key is to supplement iodine scientifically.

Iodized salt, which was originally used to prevent big neck disease, is now suspected of having health risks and has become the "murderer" of citizens' excessive iodine intake. The voice of "independent iodine supplementation" among the people and the medical profession is getting higher and higher. Some people began to reflect on the widespread iodine supplementation in coastal areas and boldly put forward the conjecture that "iodized salt causes disease" on the Internet.

Residents in iodine-deficient areas must eat iodized salt scientifically for a long time, otherwise once they stop using it, iodine deficiency disorders will recur; Don't buy too much iodized salt every time, because iodine will evaporate after a long time; The container of iodized salt should be covered and placed in a dry, dark and high temperature place.
