Introduction of iodine:
Iodine is an essential nutrient for human body. If iodine is deficient, it will seriously affect our health. Thyroid diseases are caused by iodine deficiency. Children's iodine deficiency will also affect their intelligence level and learning ability. Iodine deficiency in pregnant women will lead to fetal death, abortion, premature delivery and teratogenesis, and the physical strength and labor ability of adults will decrease. Therefore, although the demand for iodine is small, iodine is very important.
Other ways to supplement iodine:
1. Eating iodized salt is the safest, simplest and most economical preventive method. Everyone can meet the body's demand for iodine by taking 8 grams of iodized salt every day, and this supplement is long-term. Usually, you can choose iodized salt to cook food. As long as you eat normally, the average person will not be short of iodine. Iodized salt is very cheap, and it is most suitable to eat iodized salt to prevent iodine deficiency.
2. Pay attention to the use of iodized salt. Iodine is a substance that decomposes easily when heated. Therefore, when using iodized salt, it should be noted that the initial storage time should not be too long. Secondly, it should not be stored in a cool and dry place at low temperature. Finally, you need to pay attention to the addition time. When cooking soup, add salt when cooking.
3. Eat food rich in iodine properly, and the iodine content of food in the ocean is the highest. Many seafood, such as kelp, seaweed, shellfish, marine fish, shrimp and crab, are rich in iodine. The iodine content of eggs and milk on land is relatively high, followed by freshwater fish, whole grains and bean products, and the iodine content of fruits and vegetables is the lowest. You can choose the right food to eat according to your needs.
Expand knowledge-note:
However, iodine should not be excessive. Both iodine deficiency and iodine intake can lead to thyroid diseases, so try not to supplement iodine with drugs. Dietary supplements are the safest.
On the basis of eating iodized salt, it is enough to add some foods rich in iodine. The principle of iodine supplementation is to make up as much as possible, not to make up a lot blindly. If you want to supplement iodine in large quantities, you'd better consult a doctor.
