Iodine is a trace element essential to our body, it is mainly present in the oceans.

Iodine is concentrated in the thyroid gland where it is involved in the synthesis of thyroid hormones. These hormones are involved in many reactions essential to the proper functioning of our body.

It is imperative to know that iodine deficiency can lead to numerous complications such as irreversible mental retardation in children, called cretinism, but also to goiter (increase in the size of the thyroid), as well as edema (swelling).

Iodine deficiency mainly affects people who follow a strict salt-free diet or a vegan or vegetarian diet (no meat or fish, shellfish, ..).

Iodine is used to remedy a deficiency, to stimulate the release of secretions from the bronchial tubes (expectorant), to relieve pain caused by cysts (small balls that can be filled with a liquid) in the breast.

However, due to the potential toxic effects of iodine in high doses, other substances are used to treat these different problems and limit its use.

It is important to know that in case of a radioactive nuclear accident, potassium iodide is rapidly distributed to the population to saturate the iodine receptors in the thyroid gland and prevent the fixation of radioactive iodine with a high carcinogenic potential.

Iodine consumption should not exceed 200 micrograms per day in pregnant and lactating women.

You must be very careful, because iodine can cause allergic reactions in some people, resulting in the appearance of skin rashes, fever and edema.

Iodine can also cause side effects such as heart rhythm disturbances, particularly palpitations in the elderly, and symptoms of hyperthyroidism (weight loss, heat intolerance, irritability, confusion, tingling).

Iodine poisoning is called iodosis and is characterized by headaches, breathing problems, sore throat and eye irritation.

It is important to know that iodine can interact with anticoagulants (warfarin, coumadins) by reducing their effectiveness. Some treatments such as lithium used to fight bipolar disorder, reduce the absorption of iodine.

I would like to reassure you that salt is generally supplemented with iodine to meet our needs in this trace element.

Eating fish, seafood, shellfish and seaweed also helps meet our iodine needs.

It is interesting to know that meat, poultry, eggs and dairy products may also contain iodine due to the intake of iodine-enriched foods from these species.

Some foods can reduce the absorption of iodine by the intestine like cabbage, broccoli, ...

Finally, I would like to draw your attention to the fact that iodine supplementation outside the diet in the form of food supplements should only be done under medical advice.
