The nutritional value of iodized salt

June 08, 2018

The iodide salt refers to potassium iodate (KIO3) sodium chloride (NaCl). The World Health Organization recommends 6 grams of salt per person per day, but Chinese citizens generally exceed 20 grams. This requires the provision of iodine-free salts for human selection at the same time, otherwise there is a high risk of excessive intake of iodine.

We first need to understand what are the main physiological functions of iodine? Studies have found that the major physiological functions of iodine are accomplished through thyroxine, and no independent physiological function has been found for iodine. Therefore, the physiological function of iodine described below is the physiological function of thyroxine.

1. Promote energy metabolism: promote catabolism of substances, generate energy, and maintain basic life activities;

2. Maintain the physiological function of the pituitary;

3. Promote development: Growth, development, and sexual development of children's height, weight, bones, and muscle all depend on thyroxine. If iodine is absent at this stage, it will lead to children's stunting;

4. Promote brain development: In the early stages of brain development (from the beginning of pregnancy to the age of 2 years after the baby is born), the human nervous system must rely on thyroid hormones. If iodine is missing from the diet during this period, it will cause the brain of the baby. The backward development, serious in the clinical above referred to as "little small disease", and this process is irreversible, and later even if you add iodine, it is not possible to return to normal.

Iodized salt has made great contributions to helping people supplement iodine and prevent diseases, but to make iodized salt work fully, it needs to pay more attention in daily life.

First, iodized salt should be bought less and eaten in time. Buy iodized salt should not be too much at a time, you can eat and buy again to avoid the volatilization of iodine.

Second, do not add too much vinegar when eating iodized salt. When iodine is combined with acidic substances, its efficacy will be affected. When iodized salt is eaten with vegetables with sour taste (such as tomatoes, sauerkraut, etc.), its efficacy will also be affected.

Third, iodized salt should be placed in a container, sealed and stored in a cool, ventilated, dark place to ensure its effectiveness.

Fourth, we must grasp the timing of the release of iodized salt. Iodized salt is volatile due to heat, so when cooking or soup, because of the higher temperature, should not be placed in iodized salt, salt should be placed in the dishes or food fast when iodized salt.
