Fruits that do not contain iodine. Natural sources of iodine
Iodine is one of the most important elements for the functioning of the thyroid gland. It is part of the hormones produced by this gland, and it, in turn, is considered incredibly necessary for the human body. But, regrettably, the modern population sometimes has a catastrophic deficiency of such a microelement. And this entails a bunch of health problems: fatigue, weakened immunity, hair loss, heart pain and other ailments. A person should receive only 150-200 micrograms of iodine per day. In a lifetime, a person consumes only one teaspoon of such an element, but its importance is simply invaluable. Therefore, in our article we will consider which iodine-containing products are better for the thyroid gland, get acquainted with the symptoms of a lack and excess of halogen, and other hypotheses related to this microelement.
The benefits of iodine
The body of an adult healthy person contains about 15-20 mg of iodine. And its benefits are simply indescribable. So, first of all, this element has an impact on the health of nails, teeth, skin and hair. It is also needed for the normal functioning of the immune system. If a person receives a sufficient dose of iodine, then he will be cheerful, energetic, cheerful and cheerful.
By using iodine-containing products, we improve the processes of fat metabolism in the body. And this leads to the elimination of cellulite and facilitates the burning of excess fat during the diet. Halogen is directly related to mental development. It is needed for the proper functioning of the brain. And it is especially necessary for pregnant women, as it helps to form a mentally complete and healthy child.
Iodine is actively used to treat rickets, gout, rheumatism, hematomas. Iodine inhalations are an adjunct in the treatment of colds and throats.
Foods containing iodine
This element enters the human body exclusively from the outside. And this means that it is necessary to consume iodine-containing products. And the amount of its ingestion into the body depends on how enriched the products are with it. People are used to thinking that iodized salt will be the solution to the whole problem and are actively starting to buy one that contains iodine instead of the usual seasoning. But this is not correct at all. If you have not used an open package for two months, then it loses almost all of its qualities.
Water is also considered a source rich in iodine. In one liter of liquid, there are approximately 15 micrograms of the substance we need. Other iodine-containing products for the thyroid gland and not only are sea water and seafood. One hundred grams of delicacies such as crabs, scallops, oysters, squid, shrimp and mussels contain 100-300 micrograms of iodine.
50-190 micrograms of the microelement is also found in marine fish, while freshwater inhabitants cannot boast of such indicators. Considering iodine in foods available to every average person, butter, cereals, pork, bread, milk, eggs and beef should be highlighted. There is iodine, of course, in the fruit and vegetable diet. These include persimmons, potatoes, strawberries, garlic, tomatoes, eggplant, onions, oranges and bananas.
Top five delicacies
The question of which foods have more iodine can be answered as follows: there are five dishes that are better than others enriched with this trace element.
So, in the first place is red caviar. This is one of the most valuable products. Its protein is absorbed by the body much better than the protein found in meat and dairy dishes. Caviar contains a huge amount of iodine in an easily digestible form. Second place rightfully belongs to seaweed. It is necessary to eat one hundred grams of such a snack every day in order to provide the body with a daily dose of iodine.
The third position in the category "iodine-containing products" can safely be given to cod liver. In addition to this ingredient, it also has many other useful substances, such as Omega-3 and various vitamins. Persimmon is also one of the top five foods high in iodine. If not all gourmets like seaweed or cod liver, then almost every one of them likes the fruit. And, finally, buckwheat is in fifth place. Among all cereals, she has the most iodine.
Who needs iodine and how much
Foods rich in iodine must be consumed by all people without exception. But its daily requirement is different for everyone. So, for one kilogram of body weight, you need from two to four micrograms of halogen. In an adult male, this rate is 150-300 mcg per day. If problems with the thyroid gland are observed, then the dose should be increased to 400 mcg.
Young women during puberty, as well as pregnant women and mothers who are breastfeeding children, should receive more than 400 micrograms of iodine. Therefore, iodine-containing products are recommended to be put in their diet in the first place. Infants need to consume 50 mcg of this element per day, in children from two to six years old, the norm is 90 mcg, up to 12 years it should be increased to 120 mcg.
oversupply
An excess of iodine in the body is just as dangerous as its deficiency. Therefore, it is often better to use foods rich in iodine with extreme caution. The increased content of this element in the body can be caused by the fact that the regulation of iodine metabolism is disturbed, or a person receives an excess of the trace element, more than 600 mcg per day.
If too much iodine has accumulated, then the body will react with the following symptoms: fever, a metallic taste in the mouth, sudden weight loss and a tendency to diarrhea. You may also experience weakness in the muscles, sweating, frequent colds, premature graying of hair and other ailments.
If there is not enough iodine
With a deficiency of halogen in the body, a person will immediately feel it. He will become more aggressive, his character will deteriorate, his voice will become hoarse, chronic constipation will become a common occurrence for him. In addition, his memory will deteriorate greatly, arrhythmia will begin to develop and the level of cholesterol in the blood will increase. Find out which foods contain more iodine to avoid sudden changes in blood pressure, puffiness, brittle hair and fatigue.
The largest amount of iodine is found in feijoa. There are 350 micrograms per hundred grams of fruit here. Seaweed and squid have 300 micrograms of the element per 100 grams. In the same amount of flounder, shrimp and hake, there are 190, 180 and 160 mcg, respectively. But in pollock and cod, these figures reach only 150 and 135 mcg. In milk, there are only 16 micrograms of iodine per hundred grams, and in hard cheese - 11. In pork, the figure is determined at 17 micrograms, and in beef - 11.
A little more about iodine itself
Iodine in foods is of great benefit to the life of the human body. But it is also important in other areas. After all, this is an element of chemical origin, and it has a wide variety of positive properties. It is actively used in various fields. But most often it is used in medicine and technology. It is necessary for the production of batteries, light sources, LCD monitors. And his main medicinal properties are disinfectant.
Iodine is an important element found in small doses in water, air, soil and almost all living things (from plants to mammals).
This substance is vital for all people.
When there is enough iodine in the human body, the body functions correctly, so it enjoys life in all its manifestations.
A person receives iodine from food. In small doses, this substance comes with water, air. The body needs it for the thyroid gland. If it is not enough, there is hypothyroidism, atherosclerosis, goiter. The hormone thyroxine (interrelated with iodides) affects the development of the body, metabolism. Foods rich in iodine help burn calories, fat is converted into energy, hair roots are strengthened, immunity is increased, and the risk of cancer is reduced.
Iodine and selenium are closely related. These hormones synthesize ATP. Iodine deficiency causes a decrease in metabolism. It affects the work of the central nervous system.
Pregnant women, children under 15 years of age should receive enough of this element from the diet (). Which product contains more iodine, you will learn from the table and detailed list in the middle of the article. It is difficult for children with iodine deficiency to learn, new skills and knowledge are absorbed worse. It is also helpful to add iodized salt to your diet.
Signs of shortage
If a person does not receive enough iodine during prenatal development, then hypothyroidism develops, which becomes the cause of deep disturbances in the functioning of higher nervous activity.
What does it contain
What foods contain iodine and where is the most of this important element? There is a lot of this substance in marine, oceanic inhabitants, plants. Where is the most iodine in food, the table will tell better. These are fish, seafood, kelp. These are the main natural sources of natural iodine, which are extremely beneficial for the thyroid gland. To know where iodide is, you need to keep a list or table with exact numbers on hand.
The content of iodine in food products is indicated in the table. And the lists will tell you which food is better to exclude from the menu, and which to add. Find out if your iodine level is high, low, normal, low, or high. If you have an elevated level, then you need to eat less food. For the thyroid gland, it is important how much iodide a person consumes.
An adult needs 150 micrograms of iodine per day. Children need 120 micrograms. Pregnant women - 175-200 mcg.
- White beans. Legumes have a low glycemic index. Metabolism improves.
- Seaweed. That's what contains a lot of iodine. Laminaria has a minimum of calories, which is especially important for those who want to lose weight. Also, nori sheets are made from kelp, into which rolls are twisted.
- Strawberry. In winter, there are no juicy and tasty strawberries. But in the summer you need to eat 200 grams of this product. One serving contains 13 mcg.
- Prunes. Thanks to the use of this product, the likelihood of obesity is reduced, bones are strengthened, and blood sugar levels are reduced. Prunes also contain beta-carotene and vitamin K.
- Shrimps. This seafood eliminates free radicals, which are the cause of many diseases. The work of the brain and nervous system improves, memory functions are normalized, and the risk of brain diseases is reduced.
- Cod, tuna. This fish is a source of protein, so useful to people who take care of food. Fish contains a lot of magnesium, potassium, phosphorus, calcium, vitamins E, B.
- Turkey fillet. This product is useful for those who are on a diet and seek to get rid of extra pounds.
- Potato. To maintain the benefits, you need to eat baked potatoes. The body protects itself from diseases of the nervous system, the bones are saturated with calcium.
The following foods are rich in iodine:
- algae, seafood, fatty sea and ocean fish;
- fruits and berries: grapes, apricots, plums, apples;
- meat: chicken, turkey, nutria, rabbit (if the animals are fed accordingly);
- dairy products: milk, cottage cheese, cheese;
- vegetables: carrots, salads, beets, tomatoes.
If there is little iodine, then the products contain ten times less of this element. Many soils that are far from the sea store a minimum of this substance.
Iodine deficiency causes depression, disrupts the functioning of the brain, stimulates weight gain. To protect yourself from such troubles, you need to eat foods that contain more iodine.
In addition to plants that are sources of this substance, there are antagonist plants. These are flaxseeds, raw cabbage, soybeans. There are substances that do not allow iodine to be absorbed. To compensate for iodine deficiency, it is necessary to enrich the body with foods that contain enough iodine. It is important to remember that most of the iodide is destroyed by heat treatment. Therefore, it is necessary to use drugs.
Table of products containing iodine
If iodine deficiency occurs, then products containing iodine are extremely useful. They must be consumed in large quantities. Which product is good for the thyroid gland, and which is not, decides the presence of iodide. A table and a list of foods for the thyroid gland will help you understand which foods have a lot of iodine and which are the most beneficial for the thyroid gland?

What foods do not contain iodine. Iodine free diet before radioactive iodine treatment
People who have thyroid problems should either increase the number of iodine-rich foods on the menu, or follow an iodine-free diet, excluding food, where there is this substance.
Some foods contain little of this substance, so you can eat them as much as you want:
- fruits (bananas, citrus fruits, currants, pears, cranberries, currants);
- fresh juices (any);
- vegetables - forget about potato peels, legumes;
- unsalted peanuts, almonds and other nuts;
- sugar, honey;
- seasonings: fresh and dry herbs, black pepper;
- vegetable oils;
- caffeinated drinks, alcoholic drinks;
- egg whites and products where they are used;
- fresh meat (you can eat up to 150 g of pork, veal, beef, lamb), cut the meat into small pieces;
- cereals, cereals (you can eat up to 4 servings daily).
If you need to undergo radioiodine therapy, then you should include in the diet products that will create iodine deficiency artificially. The daily dose should not exceed 40-50 mcg.
The normal functioning of the body depends on the amount of incoming nutrients. Iodine is especially important for humans. It has a beneficial effect on the state of the thyroid gland and the production of hormones, participates in biochemical processes, the activities of many organs and systems. To avoid the lack of an element, you need to know which foods contain iodine and what are its daily norms.
The role of iodine in the body
Iodine is an important element that is involved in the work of many systems and organs. It is especially necessary in the cases described below.
- For the full functioning of the thyroid gland. Promotes the production of hormones involved in metabolic processes and adaptive reactions.
- To normalize the metabolism of subcutaneous fat cells. Prevents the appearance of cellulite.
- For the normal functioning of the nervous system. Helps the growth of nerve cells, improves mood, relieves irritability, fatigue.
- For the harmonious neuro-psychological and physical development of children. Prevents the development of congenital malformations.
- Participates in lipid and carbohydrate metabolism.
- Improves the condition of hair, teeth, nails.
Under the influence of the mineral, hormones such as thyroxine, triiodothyronine and diiodothyronine are produced. They are necessary for the regulation of energy metabolism in cells, the removal of harmful substances, the fight against infections, and the normal functioning of the pancreas. Thanks to thyroid hormones, heat exchange is ensured, the intensity of respiration is monitored. Iodine is an active participant in the synthesis of phagocytes and proteins. Participates in the construction of bone and cartilage tissue, has a positive effect on performance and brain activity.
daily requirement
The need for iodine depends on age, sex, conditions environment and health status. During puberty, during pregnancy or when hypothermia, the body needs more mineral. If the daily norm of iodine for an adult is 150 micrograms, then pregnant and lactating women need at least 200 micrograms.
In total, the body contains up to 25 mg of the mineral. More than half of this volume is in the thyroid gland, about 5-10% - in the blood. To calculate the daily rate, it is enough to remember the proportion: 3 μg of iodine per 1 kg of weight. Based on this, 50 micrograms of a trace element will be enough for children up to a year, from 1 year to 2 years - 75 micrograms, from 2 to 6 years - 90 micrograms, from 7 to 12 years - at least 120 micrograms.
Scarcity and surplus
Lack of iodine leads to serious disturbances in the functioning of the body. Among the most common causes of a mineral deficiency are an incorrectly formulated diet, a lack of seafood, iodine metabolism disorders, taking medications that impede the absorption of a trace element, environmental pollution, and high sensitivity to allergens.
With a lack of iodine, the thyroid gland suffers first of all. It loses activity, which leads to the development of hypothyroidism, which is manifested by swelling of the mucous membranes, a slowdown in metabolism, and skin aging. Too much iodine is the cause of hyperthyroidism. Against its background, Graves' disease and endemic goiter occur.
Iodine deficiency provokes the development of numerous negative phenomena.
- Emotional instability, which is accompanied by drowsiness, irritability or apathy, lethargy, forgetfulness, blues, causeless bad mood.
- Low hemoglobin level.
- Cardiac problems: arrhythmia, an increase in lower blood pressure, or atherosclerosis.
- Swelling around the eyes, face or hands. Muscle pain, sciatica, weakness.
In children, a prolonged lack of iodine leads to delays in mental, mental and physical development. The lack of a microelement during pregnancy causes the child's cretinism, serious disorders in the formation of the skeletal system and brain. In the early stages, iodine deficiency can cause miscarriage and placental abruption, and during lactation, poor milk production.
Most often, a lack of a mineral is indicated by loss of appetite, fatigue, weakness or bad mood, hearing problems, memory problems, recurrent headaches, severe hair loss, tooth decay or excessive dryness of the skin, frequent colds or viral diseases, poor heat tolerance, shortness of breath and pain in the heart.
Excess iodine is very rare. Usually it is accompanied by signs of a cold, causes hives and other allergic reactions. Mucus production may increase.
Products - leaders in iodine content
To maintain the balance of iodine, you need to choose the right foods. Among the leaders in the content of the trace element, seafood and fruits can be distinguished: bananas, citruses, watermelon, melon, apples, grapes, persimmons and strawberries. Topping the list of vegetables are eggplants, onions, garlic, radishes, and spinach. A lot of iodine is in peanuts, sweet corn, mushrooms, beans, kefir and chocolate.
| Name | Content, mcg |
|---|---|
| squid meat | 300 |
| sea kale | 300 |
| Hake, pollock, haddock | 150 |
| Grape | 8 |
| Garlic | 9 |
| Radish | 8 |
| Carrot | 5 |
| Beans | 12 |
| Millet | 10 |
| Barley grits | 9 |
| Oatmeal | 8 |
| Lentils | 4 |
| Kefir, yogurt, milk, curdled milk | 9 |
| Fatty sour cream | 7 |
| Condensed milk | 7 |
| Crackers | 10 |
| Eggs | 20 |
| Chicken fillet | 6 |
| pistachios | 10 |
| Beef liver | 6 |
It is important to remember that microelements disappear very quickly, especially when boiled. To make up for a mineral deficiency with iodized salt, it should be added to prepared meals and stored in an airtight container. It is not recommended to use salt for longer than 3-4 months, otherwise iodine will not remain in it at all.
One of the richest foods in iodine is sea kale. However, it is important to take into account that its use provokes the production of thyroid hormones. This activity is accompanied by an increased use of oxygen by cells, which can cause negative consequences in the presence of malignant tumors.
Antagonist Products
In contrast to foods rich in iodine, others interfere with the absorption of the trace element. If your task is to make up for its lack, exclude cruciferous vegetables from the diet: broccoli, white cabbage, cauliflower and Brussels sprouts. Flax seeds and soy products prevent the absorption of iodine. Therefore, when buying semi-finished products, pay attention to their composition. Sometimes they add soy as a meat substitute.
The list of foods containing iodine is quite long. If necessary, the daily norm of the element can be replenished by eating 5 apple seeds (provided that the fruits are grown in mineral-rich soil). Before including foods containing iodine in your diet, consult your doctor and make sure that you need such a diet.

Normal physical and mental development may suffer if a lack of such an important trace element as iodine appears in the human body. Since almost 90% of it comes from food, every housewife needs to know which products contain iodine in an amount that can provide the daily requirement.
Iodine belongs to the category of vital trace elements, because it is involved in the regulation of metabolic processes. Its insufficient intake in the body can not only worsen overall well-being, but also lead to the development of serious diseases. The lack of this trace element primarily affects the function of the thyroid gland. The hormone thyroxin produced by it regulates metabolic processes.
With a decrease in its quantity, rapid fatigue, lethargy, impaired memory and thinking are observed. A decrease in the iodine content in the body can slow down the physical and mental development of children, cause cardiovascular diseases, and metabolic diseases. Inclusion in the diet of foods that have iodine helps to avoid this.
How much iodine do you need
The body's need for this trace element is 3 mcg / kg per day.
The greatest amount of iodine is required for pregnant women - 200 mcg per day. Adolescents and adults need 150 micrograms of this trace element per day. Newborns receive this microelement with milk, so lactating women need to eat properly and fully.
But iodine enters the body not only with food. In coastal areas, due to the increased content in the air, part of the daily requirement is provided in the process of breathing. Drinking water also contains this trace element. It is even specially added during purification, in areas where the iodine content in natural water sources is low. Iodized salt can also help meet the daily requirement for this trace element, but with long-term storage, its amount in it decreases.
In different foods, the content of this microelement is different, so it is necessary to ensure that the diet contains foods that are rich in iodine. Sometimes the question arises whether it is possible to increase the iodine content in the body artificially, especially since our pharmacological industry has long been producing vitamin complexes, food supplements that contain this element.
This cannot be done because:
- excess also leads to the development of pathological conditions;
- iodine from vitamin complexes is worse absorbed by the body;
- normal metabolism requires a variety of substances and vitamins that can only be obtained from food.
Therefore, to ensure the daily requirement, you need to include in the diet products that contain it, and these can be:
- fish and meat;
- dairy;
- fruits and berries;
- vegetables and greens;
- cereals and legumes.
Moreover, it is impossible to use only one type of product, since a whole complex of vitamins and minerals is required for good absorption. nutrients. Vitamins A and E play a special role in metabolism. Therefore, people with thyroid diseases need them.
Fish and meat products
The concentration of iodine in sea water is high, and therefore fish dishes and seafood contain the most iodine, the table shows how much iodine enters the body when they are consumed. But we must remember that improper storage, heat treatment can not only change the taste of the dish, but also its composition.
For the prevention and treatment of thyroid diseases, our readers advise Monastic Tea. It consists of 16 most useful medicinal herbs, which are extremely effective in the prevention and treatment of the thyroid gland, as well as in cleansing the body as a whole. The effectiveness and safety of Monastic Tea has been repeatedly proven by clinical studies and many years of therapeutic experience. The opinion of doctors ... "
The richest seafood in iodine is sea kale or kelp, it contains more than 500 mcg, and 100-150 grams is enough to fully meet the daily requirement. Its dry leaves are used to treat diseases associated with a lack of this trace element.
But in meat it is less, in beef and chicken per 100 g of product there are only 5–11 mcg, pork and fresh eggs contain 14-18 mcg. There is little of it in river fish, only 74 mcg, but other useful substances (phosphorus, calcium) make it an indispensable product in the diet.
Dairy
Of the dairy products, whole milk and cheeses are the richest in iodine, in fermented milk, fatty foods (ryazhenka, kefir, sour cream, cream), its content decreases.
Cereals, legumes
Cereals and legumes also serve as suppliers of this trace element to the body. For example, beans contain 14 microns. Of the cereals, the most iodine-containing is millet (4.5 mcg), but buckwheat (4 mcg) and oat groats are not inferior to it, especially since they are used for cooking more often.
Fruits and vegetables
The content of iodine in vegetables, herbs and fruits often depends on the region in which they grow, so this trace element is found in cabbage, tomatoes, carrots, strawberries, plums and grapes. A certain amount of it is found in citrus fruits, bananas, apples. But the champions in quantity per 100 gr. products are persimmon and feijoa, fruits that grow in conditions of high humidity on the coast, apples with seeds.
What foods to use for iodine deficiency
The list of products that contain this element is quite large. And it is not difficult to make a diet to provide the body with this trace element. But before doing this, you need to find out the cause of the iodine deficiency.
Iodine-containing products will help to fill the deficit, although a holiday on the coast is also useful in such a situation. Try to diversify your diet with seafood, replace wheat bread rye. An excellent source of this trace element are eggs, mainly the yolk. Fresh fruits, vegetables, greens (spinach) are also useful. If possible, treat yourself to red caviar and overseas fruits (persimmon, feijoa).
A balanced diet is one of the important factors for the health of the body. Meals should be varied, properly prepared from fresh products. And then there will be no deficiency of nutrients, microelements and vitamins.
It still seems that it is not easy to cure the thyroid gland?
Given that you are now reading this article, we can conclude that this ailment still haunts you.
You probably also had thoughts about surgery. It is clear, because the thyroid gland is one of the most important organs on which your well-being and health depends. And shortness of breath, constant fatigue, irritability and other symptoms clearly interfere with your enjoyment of life...
But, you see, it is more correct to treat the cause, not the effect. We recommend reading the story of Irina Savenkova about how she managed to cure the thyroid gland...
One liter of sea water contains approximately 50mcg. Together with precipitation, the microelement enters the soil, from where it enters the products - plants, fruits, animal meat. In places that are protected from precipitation by mountains or located far from the sea, it is scarce. It is necessary for hormonal balance, optimal functioning of organs and body systems. Its sufficient intake determines mental development, intellectual abilities.
A significant part is concentrated in the thyroid gland, it regulates metabolic processes. The kidneys and saliva are excreted from the body.
- From September to January the level is reduced.
- Since February, it has been growing.
- The maximum is in May-June.
The reason for seasonal fluctuations is unknown.
Prolonged heat treatment of products containing iodine destroys the trace element. For example:
- Meat dishes lose up to 50%.
- Vegetables - up to 30%.
- Milk - up to 25%.
Therefore, iodine deficiency in the body is possible even with its sufficient intake with food.
iodine for thyroid
The intake of iodine with food is necessary for the synthesis of thyroid hormones, reducing the level and coagulability of the blood.
The thyroid gland of an adult contains up to 20–30 mg of iodine and is located on both sides of the larynx. Consists of two bodies weighing 15 g each oval. With a slow accumulation of a microelement, it is inactive (hypothyroidism). With excessively rapid accumulation, on the contrary, its activity is excessive (hyperthyroidism).
Upon receipt of products containing iodine, the thyroid gland produces hormones that regulate metabolic processes, the function of the cardiovascular, digestive system, intellectual, sexual function.
The thyroid gland produces a special hormone-regulator of the pituitary gland, which controls the intensity of the production of other hormones. The higher the content of the hormone-regulator in the blood, the less intensively the thyroid gland produces other hormones.
A malfunction of the thyroid gland affects the course, the reason for not bearing the fetus, placental abruption. Reduced and increased function violate the female cycle, cause infertility.
Disturbances in the work of the thyroid gland - the cause of mastopathy, fibroids, prostate adenoma.
The development of hypothyroidism in children leads to mental retardation, stunted growth, disproportionate development of body parts, and delayed puberty.
Signs of hypothyroidism in adults: swelling of the mucous membranes, delayed, aging of the skin, old appearance. Constant fatigue and weakness, increased risk of atherosclerosis.
Signs of hyperthyroidism: accelerated metabolic processes, weight loss, trembling of the limbs, bulging eyes, the development of Graves' disease.
With insufficient intake of products containing iodine and the development of hyperthyroidism, the thyroid gland increases in size without impaired function. Endemic goiter is diagnosed.
Its formation is the body's reaction to the lack of iodine-containing products in order to maintain the previous level of hormone production.
With a lack of iodine in foods, some of the thyroid cells increase activity. Autonomous formations that are independent of the action of the hormone-regulator form nodes. Thyrotoxicosis develops. Nodular goiter is diagnosed after 50 years of age.
Deficiency and excess of iodine
Up to 70% of the population of Russia suffers from a lack of a microelement. The following signs signal an iodine deficiency:
- lethargy, increased fatigue, fatigue;
- tearfulness, irritability, especially in the morning;
- hypothyroidism or endemic goiter.
Lack of iodine in foods - possible reason high blood pressure.
A simple test to determine a micronutrient deficiency:
- In the evening, before going to bed, soak a cotton swab with an alcohol solution.
- Apply three lines on the forearms: thin (about 1mm), medium (2mm), thick (3mm).
- If the thin one has disappeared, there is no deficiency.
- Gone are thin and medium - a slight shortage.
- All lines disappeared - lack of iodine.
Micronutrient excess is rare. Signs: increased mucus in the nose, symptoms, urticaria, other manifestations.
Daily requirement for iodine
The trace element is necessary for the body of adults and children. The need is increased during puberty, during pregnancy, with hypothermia.
For a lifetime, 3-5 g of a trace element (about a teaspoon) enters the body with food.
The daily requirement of an adult is 3mcg of iodine per 1kg of body weight.
For information: 1 g of iodized contains approximately 14 micrograms of the trace element. The daily rate is covered not only by the inclusion of iodine-containing products in the diet.
Products quickly lose the trace element due to its volatility, which is accelerated by boiling.
Therefore, iodized salt is added to ready-made dishes, stored in a sealed container. It retains the ability to eliminate iodine deficiency for 3-4 months.
With a lack of iodine content, take. Peeled from the shell quickly lose their useful properties.
Apple seeds are useful for the thyroid gland - one contains the daily norm. But provided that the apples are imported, grown in soil rich in trace elements.
Soy, flaxseed, white cabbage, cauliflower, broccoli, Brussels sprouts prevent the elimination of iodine deficiency - these products contain substances that neutralize the microelement.
For example, replacing meat with soy exacerbates iodine deficiency.
