Americans consume much less salt than China. The average adult salt intake of Americans is only 3.5g per person per day, while that of China is13g per person per day, almost four times that of Americans. People eat less salt, so they won't have overeating such as thyroid disease because of iodized salt.

In the United States, salt producers work closely with public health authorities to keep iodized salt and common salt at the same price. Newspapers are used to publicize and urge consumers to eat iodized salt to prevent iodine deficiency. Michigan's plan was very successful, and the application of iodized salt was quickly spread throughout the country.

Precautions:

Don't store: When buying salt, don't buy too much at once and store it at home, because iodine will volatilize and decompose under certain conditions.

Avoid high temperature: please be careful not to put salt when cooking, because the edible rate of salt will become lower under the action of high temperature.

Avoid salt storage in the open air: if salt is exposed to the air for a long time, iodine will easily volatilize and decompose.

Avoid adding vinegar: Because vinegar is acidic, iodine will destroy nutrients when it meets acidity.

Don't eat too much: Although salt is an indispensable condiment, eating too much is not only not good, but also has some bad effects.
