Iodized salt: Iodine is a trace element and a necessity for thyroid hormone synthesis. Thyroid hormone maintains the operation of human body and organs, and can develop the body and brain. As we all know, long-term iodine deficiency can cause "big neck disease". Eating iodized salt is of great significance to us. Of course, if there is a problem with thyroid function, the doctor may recommend non-iodized salt.
In addition, insufficient iodine intake in pregnant women will affect fetal development, and insufficient iodine intake in infants will cause dementia. For most of us, choosing iodized salt is quite safe and beneficial.
Extended data:
Iodized salt can effectively prevent iodine deficiency disorders. It is necessary to eat iodized salt scientifically and improve the utilization rate of iodine. Iodine supplementation is a long-term, daily and daily process. Normal people should always eat iodized salt, preferably every day.
Iodized salt should be stored in glass or ceramic cans, sealed and placed in a cool place at low temperature. At the same time, iodized salt should not be stored for a long time and should be purchased with food. In the past, iodized salt was made by mixing potassium iodide with salt. However, because potassium iodide is easily oxidized in the air, it will cause the loss of iodine, which is more expensive. Therefore, starting from 1989, China stipulates that potassium iodide should be added to table salt instead of potassium iodide.
Potassium iodate is a strong oxidant, which will not be oxidized in air or under light. Moreover, potassium iodate is an ionic crystal with high boiling point and no volatility, and no need to add salt before cooking or eating.
