The importance of selenium and iodine to Hashimoto’s disease

Hashimoto’s disease is the name of chronic lymphocytic thyroiditis – an autoimmune disease in which the patient’s immune system attacks his own tissues. This leads to the destruction of the thyroid gland and disorders of its work, contributing to the abnormal production of hormones and the development of hypothyroidism. 

The occurrence of Hashimoto’s disease depends on genetic predisposition and environmental factors. Among the environmental factors such as infections, cytokine therapies, lithium salts and the use of certain drugs, there is also an excess of iodine and selenium deficiency. So what is the significance of these elements in the functioning of the immune system and the work of the thyroid gland?

The importance of selenium in Hashimoto’s disease 

Selenium deficiency may lead to abnormal immune cells. Selenium sources in the diet are meat, cereals, milk products and fish as well as Brazilian nuts. In the system selenium occurs in the form of selenocysteine ​​- an amino acid responsible for the enzymatic activity of selenoproteins. Selenoproteins protect thyroid cells from oxidative stress. Selenium participates in the production of selenoenzymes, which participate in the metabolism of thyroid hormones. This element is a powerful antioxidant that protects the thyroid against the harmful effects of oxidized forms of iodine. Therefore, selenium deficiency leads to damage to thyroid cells and decrease of thyroid hormone production. triiodothyronine. 

The importance of iodine in Hashimoto’s disease 

Iodine is a basic component that is part of the thyroid hormone. When thyroxine (thyroid hormone) breaks down, iodine (around 20%) is re-used in the thyroid gland. Iodine deficiency results in inadequate amount of hormones produced, which contributes to the emergence of thyroid gland. Iodine is an element that is widespread in nature especially in the vicinity of salty water clusters. The sources of iodine in the diet include sea fish, seafood, eggs, meat and meats, turnips, kohlrabi. Excess iodine has been recognized as an environmental factor that affects the development of Hashimoto’s disease. During the oxidation of iodine, free radicals are formed which, leading to oxidative stress, damage thyroid cells. Among people with Hashimoto’s disease, excess iodine and additional supplementation may accelerate the autoimmune course of the disease. Numerous studies indicate an increase in the incidence of Hashimoto’s disease in coastal states (Scandinavia, Great Britain) as well as in countries where the consumption of products rich in iodine is very high (Japan). 

Demand for selenium and iodine 

Selenium 

Demand for selenium according to Dietary Reference Intakes determined by the American National Academy of Sciences, Food and Nutrition Board. 

* 1 Recommended daily intake (RDA) – a value that satisfies the needs of more than 97.5% of the healthy population in each age group, both sexes. This value is estimated by statistical methods. 

* 2 Maximum level of intake (UL) – a value that does not cause harmful effects in healthy people, as stated in the studies under medical supervision. 

* 3 Recommended Daily Intake (AI) – the probable level of daily intake calculated from observations or experimentally determined approximations or estimates of intake of individual nutrients. The AI ​​value is given when it is not possible to estimate the RDA. 

As shown by the study, the amount of selenium intake in Poland is 40 μg and is the lowest in Europe. The optimal concentration of selenium in the blood serum is 100-120 μg, while the average serum concentration of selenium in Poland is 70 μg. 

Iodine 

The iodine demand according to the Dietary Reference Intakes determined by the American National Academy of Sciences, Food and Nutrition Board. 

* 1 Recommended daily intake (RDA) – a value that satisfies the needs of more than 97.5% of the healthy population in each age group, both sexes. This value is estimated by statistical methods. 

* 2 Maximum level of intake (UL) – a value that does not cause harmful effects in healthy people, as stated in the studies under medical supervision. 

* 3 Recommended Daily Intake (AI) – the probable level of daily intake calculated from observations or experimentally determined approximations or estimates of intake of individual nutrients. The AI ​​value is given when it is not possible to estimate the RDA. 

Excess iodine can be caused by too high intake of marine products (fish, seafood, sea algae). Among people with autoimmune diseases , iodine intake even at a safe dose for the entire population may result in negative symptoms. 

Appropriate concentration of selenium and iodine in blood serum can ensure proper immune response and improve thyroid gland function among people affected by Hashimoto’s disease. Therefore, special attention should be paid to the supply of selenium and iodine along with diet and dietary supplements.

Pink Himalayan salt – real properties and application – the healthiest salt in the world?

Pink Himalayan salt is advertised as the healthiest salt in the world. Apparently, thanks to its medicinal properties, it has been used in Pakistan for many years, but if you look closely at the salt, pink crystals, it turns out that they are not much different from the usual salt kitchen, and the claim that Himalayan salt is the cleanest and healthiest salt available on earth, which contains 84 minerals necessary for the proper functioning of the body, is a pure marketing gimmick.

Pink Himalayan salt is advertised as the healthiest salt in the world. Apparently, thanks to its medicinal properties, it has long been used in the natural medina in Pakistan, and there, at a depth of about 500 meters underground, there are deposits of Himalayan salt, formed hundreds of years ago This salt is extracted by hand and does not contain any impurities, therefore it is the cleanest salt available on earth, and additionally the healthiest, because it contains 84 minerals necessary for the proper functioning of the body. At least this is how it is advertised, and what are the real properties of Himalayan salt?

Himalayan salt – properties of the healthiest salt on earth

It is futile to look for scientific studies confirming the healing properties of the pink Himalayan salt. In PubMed database – the largest database of scientific results from around the world – there is nothing about it.

The Himalayan salt owes its pink color to the iron oxide content.

Himalayan salt is not on the US Department of Agriculture (USDA) list, which regularly publishes information on the nutritional value of various products. It is strange because – as you can learn from ads – Himalayan salt contains as many as 84 elements The information comes from the book \ Water & Salt – The Essence of Life \ by Dr. Barbara Hendel, doctor and biophysicist, and Peter Ferreira .The only people who have undertaken to study the Himalayan salt. they say that salty pink crystals are a source of almost 100 substances, including elements that positively affect health.

Himalayan salt – a source of 84 minerals necessary for the proper functioning of the body \

Himalayan salt is advertised as a source of 84 minerals necessary for the proper functioning of the body. Meanwhile, research by Barbara Hendel and Peter Ferreira shows that in Himalayan salt you can also find … uranium, neptune, plutonium and discovered by Maria Skłodowska- Curie polon and rad (the content of each of these elements is <0.001 ppm / kg). Thanks to them, Himalayan salt can be used in the kitchen to build a home atomic bomb, and there are also elements such as mercury, tal, lead , bismuth, iridium, and also those with more egotistical names – antimony, tellurium, lanthanum, cerium, praseodymium or samarium, while the content of gold and platinum explains what the people claiming that the Himalayan salt contains \ valuable ingredients \ .

Himalayan salt – help or harm?

Pink Himalayan salt – like any kind of salt – is harmful if it is consumed in excess. However, not because of the radioactive elements, because these are trace amounts, but sodium.

Himalayan salt – like kitchen salt – is mostly made of sodium. Eating it in excess can harm health … and finances, because as for salt it is not cheap (about 10 zlotys per 1 kg).

Himalayan salt – like the salt that can be found in every kitchen – in about 38 percent consists of sodium, which in too large amounts can contribute to hypertension, and further to kidney problems, heart attacks or strokes. It is not true, therefore, that pink Himalayan salt supports the circulatory system, lowers blood pressure, etc.

Supporters of Himalayan salt may argue that it contains a large amount of potassium (3.5 g / kg), calcium (4.05 g / kg) and iron (38.9 ppm). Indeed, against other elements found in However, according to the recommendations of WHO, the daily dose of salt should not exceed 5 g, or about 1 teaspoon.And in this there is only 0.0175 g of potassium and 0.02 g of calcium. impact on health.

Himalayan salt – does it contain iodine?

The content of iodine in the pink Himalayan salt remains a mystery – some sources say that it does not contain this element and must be enriched. However, according to the data in the book Water & Salt – The Essence of Life, it appears that in Himalayan salt you can find <0.1 g / kg, i.e. <10 mg / 100 g of this element, iodine is essential for the production of thyroid hormones. Long-term deficits lead to hypothyroidism, enlarged thyroid gland and goiter. Pregnancy can cause irreversible hypoplasia of the brain and cretinism, it can also cause reproductive disorders and higher mortality in children. Normal salt does not contain iodine, therefore in Poland since 1997 the obligatory enrichment of table salt intended for direct consumption of iodine in the amount of 2 , 3 ± 0.77 mg in 100 g table salt.

Chemical elements are the building blocks of all terrestrial matter.

Some of them occur in the free state, others only in the form of chemical compounds or mixtures. They also find application in the human body, where their activity is really wide. Our article presents several of them and their role in human metabolism.

 

  1. What is behind the symbol B?

Boron is a chemical element naturally occurring in the human skeleton as well as the spleen and thyroid. In terms of chemical structure is similar to carbon and silicon. The natural sources of this microelement include nuts, as well as fresh fruits and vegetables and whole grains.

In the context of sports activity, the boron finds its place as a supportive measure for players professionally practicing strength and endurance sports or bodybuilding. In addition, it can be with successes used by people exercising amateurly due to for its pro-health character.

Boron is a semi -meter with a very wide action in the context of the human body. Among the numerous benefits of its use, it is mentioned inter alia

– stimulation of the increase in testosterone and estrogen activity

– osteoporosis prophylaxis and skeletal system effects by preventing the loss of calcium;

– antiseptic and antiviral activity;

– protection against breast cancer;

– affecting the activity of enzymes;

– improving the metabolism and metabolism of protein substances

Boron dosage, like most supplements, should take place in accordance with the current needs of the body for this element. Studies show that the daily dose of boron should vary from 4 to 10 mg.

 

  1. And like iodine

Iodine is a mineral that occurs under three different forms – water-soluble iodide, inorganic iodine or salt. This element is obtained from seaweed, which can concentrate almost 30,000 times higher amounts of this substance than those found in the water itself. Finding its sources among food products, pay attention to onions, milk, pork and beef, sunflower seeds and nuts

Iodine is primarily responsible for the regulation of thyroid hormone levels – thyroxine and triiodothyronine. Shortages of these compounds can be the cause of weakening of cognitive functions. This means that this element regulates the functioning of the nervous system. In addition, he is responsible for

– improvement of physical efficiency;

– nutrition of the skin, hair and nails

– prevention of the will.

Iodine supplementation, however, is not very popular. deficiencies in developed countries are rare, due to the varied diet. Therapy using this element can be started provided that you stop consuming salt and algae-based products. It is assumed that the daily dose, after fulfilling the above recommendations, should be from 0.075 to 0.15 mg. Higher portions can lead to suppress thyroid function.

  1. A few words about manganese

Manganese is defined as a transition metal that does not occur in nature as a free element. In most cases it is found in relationships with iron or other minerals. It is found among others in nuts, whole grains and vegetables such as beetroot, peas, spinach, potatoes, as well as green and black tea.

Without a doubt, manganese is an important ingredient for our health. In addition to stimulating the process of vitamin absorption and cell antioxidation, she is also responsible for

– regulation of the metabolism of proteins, sugars and lipids;

– removing the feeling of tiredness;

– memory improvement;

– regularity of muscle reflexes

It is also worth mentioning that manganese deficiencies can cause significant problems. It is mentioned here about osteoporosis, osteoarthritis, increased risk of epilepsy and a negative impact on fertility. Daily dose of manganese for men, it is about 2.3 mg, and for women 1.8 mg.

 

  1. How does selenium work?

It is not counted as one of the twenty-four basic vitamins and minerals to maintain optimal health. In the human body, as well as in nature, it can be found only in trace amounts, which is why it is included in micro-components.

When talking about foods in which it occurs, yeast, mushrooms, eggs, kohlrabi, nuts, tomatoes, cereals, fish and asparagus are mentioned. In order to improve general well-being and health, it is assumed that a selenium dose of 200 to 300 mg per day is sufficient.

Selenium has primarily antioxidant character

– in addition to removing free radicals and protecting erythrocytes against their toxic effects, it affects a number of other aspects of our body.

I am talking about here

– antitumor prophylaxis;

– effects on the immune system (antisepsis)

– prevention of cardiovascular disease;

– anti-proliferative and anti-inflammatory effect.

 

  1. The element of seafood

Vanadium is a chemical element resistant to various substances such as water, nitric acid and sulfuric acid, as well as bases.

Nevertheless, it is found within bone tissue and in a negligible amount in food. The source is seafood, i.e. oysters, mussels, lobsters, crabs and snails. In addition, this element occurs in whole grains, as well as in dill or parsley.

Vanadium is used primarily in the treatment of diabetes

– its effect is similar to the mechanism of insulin. It eliminates excessive pressure and normalizes the level of sugar in the blood. This element is also used in the prevention of heart attacks and prevents the accumulation of bad cholesterol (LDL) in the blood vessels.

The action of vanadium is still not fully understood, which is why continuous research is being carried out to show its impact on human health.

At present, it has been confirmed that vanadium has mainly prophylactic activity in the context of the proper functioning of the cardiovascular system. The daily dose taken once a day by mouth should be 100 mg in people with moderate glucose tolerance.

 

  1. An iron ally

Iron is one of the most important minerals, which is part of hemoglobin – the basic oxygen transporter throughout the body. In natural food it is found in meat products, liver, fish, egg yolks, curd, nuts, milk, legumes, shrimps, broccoli and spinach.

The element with the symbol of Fe is responsible for binding carbon dioxide (being part of hemoglobin) and directing its transport to the lungs, from where it is then removed. What’s more, it determines the proper functioning of the body and it should be used, among other things in disorders of circulation, reduced immunity and physical performance, problems with concentration and worsening of the condition of hair or nails.

Iron supplementation depends primarily on sex.

The current norms recommend the following daily doses of the element

– 19 mg for adult women;

– 25 mg for pregnant women

– 17 mg for adult men

It is also worth mentioning that substances contained in some plants contribute to limiting the absorption of iron. Chilli pepper is here (4.23 g of this product reduces absorption by 38%), rosemary as well as coffee and tea.
