What is the main food source of iodine?

Seafood has the highest iodine content, especially kelp, jellyfish, laver, moss strips and mussels. The iodine in seafood is several times as high as that in land plants, and some are as high as dozens of times. Usually, the iodine content of kelp we eat is 0.0 mg/kg/kloc-0. Seafood is a kind of food with high iodine content in nature, so we should pay more attention to this kind of food at ordinary times. They are the best natural iodine supplement products.

2. Spinach and celery

The iodine content of most terrestrial plants is low, with an average of no more than 65438 0.0 mg/kg. Only spinach and celery have higher iodine content, which can reach 1.64mg/kg and 1.60mg/kg.

3. Marine fish and laver

Eating kelp regularly can not only supplement iodine in the body, but also ingest other kinds of trace elements, amino acids and vitamins.

Function and use of iodine

1, iodine is extremely important to the life of animals and plants.

Iodide and iodate in seawater enter the metabolism of most marine organisms. In advanced mammals, iodine is concentrated in the thyroid gland in the form of iodinated amino acids, and iodine deficiency can lead to goiter. About two thirds of iodine and its compounds are used to prepare preservatives, disinfectants and drugs, such as tincture of iodine and iodoform chloroform.

Sodium iodate as a food additive is not enough to supplement iodine intake. Radioisotope iodine-13 1 is used in radiotherapy and radioactive tracer technology. Iodine can also be used to make dyes and photographic films. ?

2, the use of iodine

It can also be used as a tracer for system monitoring, such as geothermal system monitoring. Silver iodide (AgI) is not only used as a sensitizer for photographic negatives, but also as a seed to form clouds during artificial rainfall. Alcohol solution of iodine and potassium iodide is a commonly used disinfectant. Iodoform (CHI3) is used as a preservative. ?

Calibration of sodium thiosulfate standard solution. Determination of iodine value of oil. Color reaction of magnesium with acetate. Make iodoalkane and iodide. Colorimetric determination of starch. Determination of serum non-protein nitrogen and amylase. Preparation of blue iodine solution with fastness to sunlight and toluidine. Catalyst. disinfectant

Iodine tincture, compound iodine solution, iodine throat tablets, iodine glycerin and other iodine preparations are widely used in medical treatment. Iodine tincture is a common disinfectant in the family.

3. Physiological function

Iodine is closely related to human health. Adults contain 20-50 mg of iodine, which is an essential element to maintain the normal function of human thyroid. If the human body lacks iodine, it will suffer from goiter. Therefore, iodide can prevent and treat goiter.

Iodine is one of the essential trace elements for human body and is called "intellectual element". The total amount of iodine in healthy adults is about 30 mg (20 ~ 50 mg), of which 70%~80% exists in the thyroid gland.
