Levy and be in infantile state；The adult of iodine deficiency, occur light, in, the goiter of severe, i.e. so-called " big neck bubble ", sexuality declines
Move back and even lose, pachylosis, skin falling out etc..These situations are referred to as iodine deficiency, as the term suggests, it is simply that due to iodine deficiency
Caused.
Nineteen ninety JIUYUE, in " children living, protect and develop Universal Declaration " of 71 states summit meetings signature, it is determined that
Within 2000, the whole world realizes eliminating the target of iodine deficiency.In March, 1991, Chinese Government is word at declaration good sign, indicates China
The solemn commitment of nation's quality improves in government.
Owing to iodine is a very active element, it is easy to volatilization.For ensureing Iodized salt quality, it is necessary to tightly pack, it is to avoid wind
Blow, Exposure to Sunlight, the impact such as high temperature.At ordinary times should be iodine salt in the altar tank added a cover, never washing, pot are endured.Cooking is stewed soup and first to be descended dish
After put salt, the quick-fried pot of iodine salt must not be used, in case iodine crosses heat sublimation.Lesion resident summarizes iodine salt disease preventing and treating with jingle
Experience: " often eat iodine salt benefit many, the most anti-tumor of the most anti-moronism, keep properly volatilization prevention, cooking is stewed soup the most quick-fried pot ".
China is one of country that iodine deficiency harm is the most serious in the world, and former disease population reaches 4.78 hundred million, accounts for people from lesion, the world
Mouthful 40%, account for Asia 60%, the existing Mentally deficiency of China reaches 10,170,000, wherein 80% is above causing due to iodine deficiency,
The annual newly-increased intelligence disabled child child in the whole nation reaches 1,000,000 simultaneously.According to investigations, the child average IQ compared with normal child in iodine deficiency area is low
10-15 percentage point.For preventing the disease caused because of iodine deficiency, China announces annual May 5 and is set to whole nation iodine deficiency publicity
Day.
China is in December, 1972, and State Council discloses " supplementation of iodine salt prevents and treats endemic goiter Tentative Measures ", respectively
Ground achieves achievement highly visible in terms of controlling or eliminating iodine deficiency.But in recent years, due to Sal marketing management
Confusion, Non-iodizedsalt district transprovincially writes off serious so that once obtaining the iodine deficiency bottom out again of basic controlling, some areas are very
The biggest to rise amplitude.
