After the nuclear radiation event in Japan, many people so afraid of radiation that they rush to purchase iodized salt. However, is it true that iodine could prevent radiation? Here, I will introduce the physiological action of iodine and tell you what foods contain iodine. The physiological role of iodine in the body is realized through the synthetic thyroid hormone, which is one of the most important hormones in the body. It could not only maintain the body's energy metabolism through breaking down materials to provide the energy required for life activities, but also produce heat to keep body temperature. The decreased thyroid hormone synthesis caused by iodine deficiency will lead to the damage to basic life activities and physical decline. This influence could last the lifetime. Promote physical development. Thyroid hormone could regulate the bone development, sexual development, muscle development and weight and height for children. Thyroid hormone deficiency can lead to physical retardation, sexual retardation, short body, muscle weakness and other symptoms and signs. It could affect the brain development. In the period of fetal or infant brain development, it must depend on thyroid development and iodine deficiency can lead to brain development retardation of various degrees, which may result in mental retardation. This disorder is essentially irreversible, and if people supplement iodine after the critical period, it has no change in intelligence but to ensure normal physical development, correct the thyroid dysfunction, recover physical activities and improve mental activities. What foods are rich in iodine? Foods with high content of iodine are mostly seafood, such as kelp, seaweed, fresh octopus, scallops, mussels, sea cucumbers, lobsters, etc. Fresh kelp has 2000 mg iodine every one kg, which ranks first in seafood. It is followed by marine fish and shellfish category. In addition, the iodine content in salt is very little and it is only 20mg/kg in sea salt. If people take in 10g salt every day, the iodine they could get is only 2 mg, which is far from the needs to prevent iodine deficiency disorders. Obviously, iodized salt has no effect in protecting people from the harm of nuclear radiation.
