You’ve probably heard the term “goitrogenic” because many people have problems with the thyroid gland. And these people should avoid certain products. But do goitrogen are harmful and should they be avoided? In this article, a detailed look at zabojnye substances, foods and their impact on human health.
Goitrogen represent compounds that interfere with the normal functioning of the thyroid gland. Simply put, they do not allow it to produce hormones. The relationship between goitrogenic and functions of the thyroid gland was first described in 1928, when scientists (studying the disease of syphilis) saw enlarged thyroid gland in rabbits, which are constantly fed with fresh cabbage.
Goitrogen and strumigenys in food
This discovery led to the hypothesis that substances contained in certain vegetables affect your thyroid if consumed in excess. This enlargement of prostate is also known as “goiter”, from which comes the term “strumigenys factor”.
What is strumigenys effect?
Most of goitrogens – naturally occurring chemicals that are in food and in medicines. These substances can interfere with function of the thyroid gland in different ways.

Some compounds induce antibodies that cross-react with gland; others interfere with peroxidase (TPO) to run properly, etc.
For people with a healthy thyroid, it is able to produce more and compensate for the lack of hormones. But in people with compromised thyroid function, it actually increases more cells trying to compensate for inadequate hormone production, ultimately produces goiter (a swelling or enlargement of the thyroid gland).
Found several types of goitrogens in different foods.
Goitrogen distinguish three basic types:
Goitrin and Rodney worked with plant damage, for example when they are cut or chew. Goitrin reduces the production of the hormone thyroxine. It is found in leaf, Brussels sprouts and canola oil.
Flavonoids are present in a wide variety of food products, for example, resveratrol in red wine and catechins in green tea.
Flavonoids are generally considered healthy antioxidants, but some of them may turn into zabojnye substances by intestinal bacteria.
There are other types sanogennykh substances in some foods that you should avoid if you have hypothyroidism.
It might surprise you to see gluten at the top of the list of potential goitrogens, but the truth is that it promotes a wide range of autoimmune reactions, ranging from celiac disease.
Gluten goes hand in hand with autoimmune diseases, such as diabetes mellitus type 1, Addison’s disease, Sjogren’s syndrome, rheumatoid arthritis and thyroid disease. It is strongly recommended to remove gluten from the diet, if you already have autoimmune disorder.
With hypothyroidism will consider the restriction of the use of wheat, barley, rye. Keep in mind that gluten is found in many processed foods, from wheat to bread and rolls.
Soy is a fairly healthy food, but it also contains zabojnye compounds, particularly soy isoflavones genistein. This connection takes the iodine molecules from the thyroid peroxidase (TPO).
Some researchers suggest that genistein and other isoflavones compete with the thyroid as alternative actions of the TPO. But recent studies indicate that until then, until a person has a sufficient amount of iodine in the diet, isoflavones have no adverse effects on the thyroid.
Another good news is that zoogenous activity of the isoflavones may be partially off cooking or fermentation. Therefore, less harmless soy products is tempeh, soy sauce, miso and NATO. Methods of processing soybeans change goitrogenous activity, they should be steamed.
Goitrogen soy can be neutralized by pairing them with foods rich in iodine. If you love soy, then always include additional iodide in the owl diet in the form of algae.
These compounds are found mostly in cruciferous vegetablessuch as broccoli, mustard, turnips. Isothiocyanates, like soy isoflavones, appear to block TPO, and can disrupt cell membranes in the thyroid.
No one will argue that these vegetables are harmful to you, given that they are filled with vitamins, minerals, antioxidants, and various nutrients.
High temperature changes the molecular structure of isothiocyanato and eliminates subagency effect. So vegetables you can safely eat, and prepare for a couple or cook, even if you have a sick thyroid.
Is there more? … Some potential zabojnye substances are present in small amounts in peanuts, pine nuts, millet, and even strawberries. But don’t worry about these substances, because these products contain goitrogen in reasonable quantities.
The list sanogennykh products
Goitrogen cause health problems:
1) simple goiter – is the main problem.
The body compensates for the decrease in production of hormones just releasing more TSH, which is to strengthen the production of hormones, after eating with goitrogens reduces TSH. But, malfunctions in the thyroid do not allow it to react to it, whereby it increases your cells.
Goiter creates a feeling of tightness in the throat, hoarseness, cough, makes breathing and swallowing more difficult problem.
Due to the inability of thyroid to produce hormones appear and other diseases.
2) mental disorders: poor functioning thyroid increases the risk of mental decline and dementia in 81% of people under the age of 75 years;
3) 53% higher risk of developing cardiovascular disease;
4) from 18 — 28% higher risk of death from heart disease;
5) people with a sick thyroid 20 — 113% more likely to be obese; In the course of a long study over 3.5 years, the patients were added to 2.3 kg more weight.
6) low thyroid during pregnancy, especially in the first trimester, can lead to impaired brain development of the fetus;
7) a 38% higher risk of hip fractures and 20% higher risk of fractures of the spine.
Practical result: the thyroid hormones regulate the metabolism and goitrogenic reduce the ability to produce hormones. They are likely to negatively affect people who already have certain problems with the thyroid gland.
How to minimize the effects of goitrogens?
If you are concerned about goitrogens in your diet, there are a few simple ways to reduce the risk of negative consequences:
1) Diversify diet
A varied diet of plant food limits the number of used goitrogenic. In addition, you will receive enough vitamins and minerals.
2) Blancherie vegetables
If you like fresh spinach or cabbage, try, blanch the vegetables and then freeze them. This will reduce their negative impact on the thyroid.
3) Cook vegetables
Avoid eating raw vegetables, and cook for at least a couple. This will help to break down the enzyme myrosinase, reducing and goitrogen.
4) quit Smoking
Smoking is an important factor that increases the risk of developing goiter.
5) Iodine and selenium
They reduce the manifestation of the effects of goitrogens. Iodine deficiency is a well – known risk factor for development of thyroid dysfunction. Good food sources of iodine: kelp, kombu, nori and iodized salt. Less than ½ tsp of iodized salt is almost completely covers the daily need.
But, consuming too much iodine, you can also have a negative affect on cancer. This risk is only 1%, so this should not bringing you much anxiety.
Selenium prevents thyroid disease. The biggest sources of selenium: Brazil nuts, tofu, fish, sunflower seeds, meat, baked beans, Portobello mushrooms, cheese.
Should I be concerned about goitrogenic?
No, not worth it. If the function of your thyroid gland is not broken, you do not need to limit the use of products containing goitrogen. Moreover, when these products are cooked properly and eaten in moderation, they are safe for everyone, even with a sick gland.
By the way, you should know that most products that contain goitrogen, it is highly nutritious. Thus, a small risk from goitrogens outweigh the other health benefits.published econet.ru.
