Iodine is an indispensable element for human body. Iodine deficiency will not only cause goiter, but also affect the development of the brain. Iodine deficiency is very common in China. About 8 1% of county water sources in China are iodine deficient. Due to the serious iodine deficiency in local food and vegetables, people are also short of iodine. Every year, there are about 800 thousand children with dementia caused by iodine deficiency, and some of them can't count when they are young.

Children should be allowed to eat enough iodine-containing food in their diet and eat more kelp and seaweed. Kelp kelp should be soaked, chopped and boiled for baby's convenience.

Using iodized salt is a good way to solve iodine deficiency. Iodized salt means adding a little iodine to salt. In practical use, it should be noted that the combination of iodine and salt is not very close. Under the condition of open storage, after a certain period of time, iodine will volatilize on its own, which will reduce the iodine content in iodized salt. Iodized salt should be used whenever you buy it. Put iodized salt after the food is ready to ensure the normal absorption of iodized salt.

Organic iodine sugar tablets made of organic iodine in seaweed are easier to be absorbed and utilized than simply supplementing iodized salt.

In addition, if pregnant women are seriously deficient in iodine, stillbirth, premature delivery and fetal nervous system malformation may occur. After birth, children will be slow, mentally retarded, short, unable to take care of themselves and become mentally retarded.
