Iodine is an essential trace element for our body.

It is mainly present in the oceans.

It is concentrated in the thyroid gland where it is involved in the synthesis of thyroid hormones.

These hormones are essential to the proper functioning of our body, they are involved in many reactions (temperature regulation, metabolisms, intestinal transit, nervous system, ...).

It is imperative to know that iodine deficiency can lead to many complications such as irreversible mental retardation in children, cretinism, goiter (increase in the volume of the thyroid) or edema (swelling).

Iodine deficiency mainly affects people who follow a strict salt-free diet or a vegan or vegetarian diet (without animal products).

Iodine is used to remedy a deficiency, to stimulate the release of secretions from the bronchial tubes (expectorant role), to relieve pain caused by cysts (small ball that may contain a liquid) that may appear in the breast (mammary cysts).

However, because of its potential toxic effects at high doses, the use of iodine is restricted, other less risky substances are used to treat these different problems.

It should be noted that in the event of a radioactive nuclear accident, potassium iodide (in tablet form) is rapidly distributed to the population to saturate the iodine receptors in the thyroid gland and prevent the fixation of radioactive iodine with 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. These reactions can take the form of skin rashes (redness, patches, etc.), fever or oedema.

Iodine can also cause heart rhythm disorders, such as palpitations in the elderly, and side effects that are similar to the symptoms of hyperthyroidism (weight loss, heat intolerance, irritability, confusion, tingling, etc.).

Iodine poisoning is called iodosis, it can cause headaches, breathing problems, sore throat and eye irritation.

It is important to know that iodine can interact with anticoagulants (warfarin, coumadins) and reduce their effectiveness.

Some treatments such as lithium used to fight bipolar disorder or manic depression, reduce the absorption of iodine.

I want 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. As well as meat, poultry, eggs and dairy products, due to the iodine-enriched foods in these species.

It is interesting to know that some foods can decrease the absorption of iodine by the intestine such as cabbage or broccoli.

Finally, you should know that iodine supplementation outside the diet in the form of food supplements should only be done under medical advice.
