What are the dangers of eating too much iodine? What is excessive iodine intake?

The three sexes in the scientific principle of iodine supplementation refer to:

1) Long-term; (2) pertinence; (3) Precautionary.

2 3 of the iodine in the human body is found in the thyroid gland, which controls metabolism, and the thyroid gland is affected by iodine. Therefore, if iodine is insufficient, it may cause mental retardation, body fatness, and lack of energy. Goiter has long been reported by Chinese scholars, and China is one of the first countries in the world to use seaweed** for this disease.

Iodine was proposed by Courtois in 1811. Most of the dietary iodine is converted to iodide in the gastrointestinal tract, where it is almost completely absorbed by the body, and after entering the bloodstream, it is distributed in extracellular fluids throughout the body. The kidneys are the excretory organs of iodine.

Although the amount of iodine ingested by the human body is small, the kidneys do not have the ability to retain iodine. A small amount of iodine is also excreted through the feces. On May 15 every year, the National Day for the Prevention and Control of Iodine Deficiency Diseases is held to promote that eating iodized salt can effectively prevent iodine deficiency diseases.

Iodized salt refers to those that contain potassium iodate (KIO3) and sodium chloride (NaCl). The World Health Organization recommends a daily salt intake of 6 grams per person, but Chinese nationals generally exceed 20 grams. This requires the provision of non-iodized salt as a choice, otherwise the risk of excessive iodine intake is extremely high.

Iodized salt refers to table salt that contains sodium chloride of potassium iodate. Since most areas of China are deficient in iodine, and iodine deficiency will cause iodine deficiency diseases, the state compulsorily adds a small amount of iodized salt to the sodium chloride table salt for consumption.

Eating iodine in moderation and eating more is not beneficial.

I hope it will help you, if you can't ask again, I wish you progress in learning! Your timely adoption is a sign of respect for the answerer!

A rational intake of iodized salt does not mean thinking about the iodine content of every food you eat. The main ways we consume iodine on a daily basis are drinking water, food and iodized salt. It's like filling a bucket with water from three different pipes at the same time, and the correct daily intake is 6 grams, which is harmful to the body.

Prevents goiter enlargement, but should not be taken in excess. I used to read chemistry to know this...

Authoritative experts in this field in China pointed out that excessive iodine can increase the risk of hyperthyroidism; It can transform latent thyroid autoimmune disease into overt disease; Long-term iodine overdose increases the risk of hypothyroidism and hypothyroidism.

The incidence of subclinical hypothyroidism was found to be doubly and double-fold in areas with excessive iodine (median urinary iodine 200 300 μg L) and in areas with excessive iodine (median urinary iodine 300 μg L), respectively. The incidence of autoimmune thyroiditis is doubled and doubled, respectively.

Iodine supplementation to excessive iodine supplementation in iodine-deficient areas can promote the development of subclinical hypothyroidism to clinical hypothyroidism. Iodine overabundance and iodine overdose are mainly harmful to people who are sensitive to iodine nutrition. This demographic includes:

People with a family history of thyroid disease, people with previous thyroid disease, people with severe iodine deficiency, and people with positive thyroid antibody. This iodine-susceptible population accounts for more than 20% of the total population. Recently, Dr. Hans Bürgi, Chairman of the Scientific and Technical Committee of the International Council to Combat Iodine Deficiency Disorders (ICCIDD), wrote an article on the dangers of iodine overdose:

Three recent large-scale epidemiological surveys in China, Turkey, and Denmark have confirmed an increase in the prevalence of autoimmune thyroid disease caused by salt iodization, which is clinically hypothyroid, subclinical, or autoimmune hyperthyroidism. "According to the expert:"In people with an autoimmune background of the thyroid gland, even a mild increase in iodine intake (250 mcg per day) causes hypothyroidism in 20% of the population. ”
