Ordinary people eat turnip and cabbage after washing and cutting, this will produce isothiocyanate, isothiocyanate this component will hinder the thyroid gland to absorb iodine, prevent the synthesis of T3, T4. This is an aggravating factor for patients with thyroid disorders. However, instead of not eating this or that, this part of isothiocyanate is nothing compared to consuming less of many nutrients.

Not only turnip and cabbage, but also cruciferous vegetables such as cauliflower, broccoli, bok choy, chard, kale, and so on, all contain this substance. However, if you don't cut or chew them, you won't damage the cell walls of cruciferous vegetables, and you won't produce isothiocyanates. However, by cutting and chewing, the cell wall of cruciferous vegetables will be damaged, and the mustard oleoresin in the cell will react with a special enzyme, glucosidase and black mustard enzyme, outside the cell, and then isothiocyanate will be generated, which will hinder the absorption of iodine by the thyroid gland.

If the whole plant was scalded, the enzyme inactivated, then how to cut how to chew will be no problem. This can solve the problem of blocking the absorption of iodine by the thyroid gland, but it is not enjoy the anti-cancer effect of isothiocyanates, so we should not boil vegetables at high temperatures for too long, which will destroy the beneficial components contained in the human body. So for people suffering from thyroid disease, must be very good control of their dietary life. Thyroid patients' absorption and metabolic function are lower than ordinary people, dyslipidemia, heart rate and other aspects will also be weak, so more attention should be paid to nutrition, on the one hand, to avoid under-absorption of nutrients, and on the other hand, to avoid excessive energy.

As we all know, the thyroid gland is our endocrine organ. It is relatively small, but it plays a different role in our body, especially in the regulation of hormones. If the thyroid gland loses its function and we don't have timely medical help, it is obvious that it is difficult for us to continue to survive.

Therefore, in real life, the vast majority of patients with thyroid disease do not dare to eat and drink, and attach great importance to the health of the thyroid gland. At the same time, people also pay extra attention to the various taboos of thyroid disease diet. This is, as the subject asked, "Why should I eat less radish and cabbage for thyroid disease?" Next, I will use this article to talk about this question in detail.

What are thyroid disorders?

● The thyroid is a small butterfly-shaped gland located at the base of the neck in the shape of a butterfly, and it is an important part of the complex gland called the endocrine system, which is responsible for coordinating many of the body's activities, such as the manufacture of proteins, the rate of appetite for energy, and even the hormones that regulate the body's metabolism.

● Hyperthyroidism occurs when the thyroid gland is overactive and produces too much hormone. Hyperthyroidism affects about 1% of women, but is less common in men. Toxic diffuse goiter is the most common cause of hyperthyroidism, affecting about 70% of people with hyperthyroidism. In addition, thyroid nodules can cause the gland to produce too much hormone. Regardless of the type of disease, most people who have an overproduction of thyroid hormones experience symptoms such as emotional agitation, increased sweating, nervousness, and difficulty sleeping.

● Hypothyroidism is the opposite of hyperthyroidism. That is, the thyroid gland is not active enough to produce enough hormones. Hypothyroidism is usually caused by Hashimoto's thyroiditis, surgical removal of the thyroid gland, or radiation therapy. In our country, it affects about 4.6% of the population in the age group of 12 years and above, but most hypothyroid patients are mild and produce symptoms that are relatively mild, such as easy fatigue, dry skin, slow heart rate, and so on.

Is it true that you should eat less radishes and cabbage for thyroid disease?

1, thyroid disease patients eat less or can not eat cabbage and radish, mainly stems from an effect called isothiocyanate. Isothiocyanates are found in abundance in almost all cruciferous vegetables such as cabbage, bok choy, turnips and so on. According to available studies, isothiocyanates prevent the uptake of iodine by the thyroid gland, thus causing goiter. In this respect, patients with thyroid disorders should indeed avoid cabbage and radish.

2, in fact, isothiocyanate on the thyroid, there is a basic requirement, that is, the effect will only occur in isothiocyanate in the blood has a higher concentration, the concentration of the value of 4.8-6.4mg / L. To achieve this value, you have to eat a large number of turnip cabbage in a short period of time 500-1,000g. I think that in the life of the people, there is not that one will have such a weird I don't think anyone would have such a strange way of eating. Besides, heavy smoking can lead to a more drastic increase of isothiocyanates in the blood, which is also a problem for people with thyroid diseases.

3. In many of our regions it is not possible to reach this value, unless one grows up in an iodine-deficient region of our country, such as Jiangsu, Xinjiang and other places. However, with the gradual prevalence of iodized salt consumption, the occurrence of iodine deficiency has gradually decreased. In this regard, thyroid disease can be appropriate to eat radish and cabbage.

4. The presence of isothiocyanates in cruciferous vegetables is an established fact that cannot be changed. Moreover, isothiocyanate has health benefits for our organism under the existing research, which can also be said to be a good thing. In real life, no one, whether a healthy person or a person suffering from thyroid disease, is likely to eat radish and cabbage every day. Instead, we focus more on a balanced diet, eating a little of everything and not much of anything.

Which groups of people with thyroid disorders try to avoid turnip cabbage?

I have already mentioned above that the question of whether you can eat turnip cabbage in thyroid disease is closely related to the fact that isothiocyanates affect the uptake of iodine by the thyroid gland. In this regard, there are these categories of people with thyroid disease who should avoid eating turnip cabbage.

• For long-term smokers with thyroid disorders, it is even more important to be aware of the effects of isothiocyanates on the thyroid gland. After all, long-term smokers have a high level of 5-20 mg/L isothiocyanate in their bodies, which is significantly higher than in the general population. Compared to the effect on the thyroid gland is even greater.
• For some patients taking medication for thyroiditis, it is also important to avoid cruciferous vegetables as much as possible. After all, thyroiditis is a disease that involves the thyroid gland, which is more damaging to the thyroid cells, and we need a lot of iodine to participate in the process of taking medication to restore the function of the thyroid gland. If we eat radish greens every day, it is very likely to affect the thyroid's intake of iodine.
• Patients being treated with Iodine 131 should also avoid eating too many cruciferous vegetables. If you are not careful, it can easily cause the effects of Iodine 131 treatment.

To conclude, cruciferous vegetables have superb antioxidant properties and are the most common healthy food in our daily life. For our healthy people, eating more of them is beneficial to our health. The overall aspect is that although they do not affect the thyroid gland, patients with these three thyroid disorders are advised to avoid them as much as possible. Or wait for the treatment period to pass before choosing to eat. This will allow you to reap the maximum benefits for your health.

[2018.01.05 Text of the main body of this title: 735 Liu Xiaohui]

This is because normal people eat radish and cabbage after washing and cutting them. All this does is produce isothiocyanates, which block iodine uptake by the thyroid gland and affect the synthesis of T3 and T4. This undoubtedly adds insult to injury for people with thyroid disease. Therefore, there is the saying that eat less turnip cabbage.

But, in my opinion, that little bit of isothiocyanate is nothing compared to not eating this, not eating that, and consuming less of many nutrients. So, my view is to eat everything.

In fact, not just turnip cabbage, but any cruciferous vegetable such as broccoli, cauliflower, chard, and chard kale will have this substance.

But why do I emphasize cutting and chewing?

There is no isothiocyanate in such cruciferous vegetables without cutting, chewing, or disrupting their cell walls by any mechanical means. It is only when the cell wall is destroyed by cutting or chewing that the mustard oleosin in the cell comes into contact with a special enzyme (glucosidase - black mustard enzyme) outside the same cell and is activated into isothiocyanate by it.

However, if you were to blanch the whole thing in water to inactivate the enzyme, then you would have no problem cutting and chewing it any more. But, while the problem of blocking iodine absorption is solved, you won't enjoy the anti-cancer effects of isothiocyanates anymore.

So what, it's even more important for people with thyroid disease to manage their dietary life well.

For patients with thyroid disease, their absorption and metabolic function will be weaker than normal, and their dyslipidemia, heart rate and other aspects will be weaker, so it is more important to pay attention to nutrition, on the one hand, to prevent under-absorption of nutrients, and on the other hand, also to prevent excess energy.

1. Eat more vegetables and fruits, which contain large amounts of vitamins, minerals, dietary fiber and plant compounds (plant compounds are not only isothiocyanates, but also beta-carotene, anthocyanosides, polyphenols, isoflavones and so on), which are easily deficient due to maldigestion and malabsorption.

2. Moderate consumption of fish, poultry, meat, eggs, milk and soybeans and their products (such as tofu, tofu skin, dried tofu, etc.), which are high-quality proteins, on the one hand, can increase one's own immunity, but also to avoid the lack of protein due to malabsorption resulting in viscous edema.

These meat, eggs and milk should be consumed as lean and low in fat as possible, after all, these patients will also have less ability to digest fat than normal people.

3. Minimize the consumption of refined white rice and noodles in the choice of staple food and eat more grains and cereals to increase the nutrient content of food and reduce energy intake.

4. Drink plenty of water, exercise and stop smoking and drinking.

Disease is a major thing that catches people off guard, and people's most basic wish is always to be healthy, free of disasters and illnesses, and to live a safe life. But these ideas are ultimately people's good wishes, sometimes the arrival of disease is often unexpected, coupled with the irregular rhythm of modern life, more or less physically there are certain problems, such as thyroid disease.

What is Thyroid Disease

Thyroid disorders, as the name suggests, are diseases that occur when there are problems with the thyroid gland, such as hyperthyroidism, hypothyroidism, etc. In general, thyroid disorders are divided into two main categories: medical and surgical thyroid disorders. Generally speaking, thyroid disorders are divided into two main categories: medical and surgical thyroid disorders. Thyroid disorders treated medically include hyperthyroidism (commonly known as hyperthyroidism) and thyroid inflammation (including acute, subacute and chronic thyroid inflammation); thyroid disorders treated surgically include goiter and thyroid tumor. Although thyroid disorders are divided into medical and surgical conditions, the boundaries between the two are not clear-cut, and sometimes the two are mostly interchangeable. Like many diseases, some thyroid disorders are polygenic, and although they are related to genes, they are also related to the environment. They are not caused by genes alone, but rather by a combination of internal and external factors (genes and environment). （However, it is important to note that some of the causative factors of thyroid disease can be passed on through the genes.)

What factors may trigger thyroid disease?

1. Deficiency of the trace element selenium;

2. Excessive iodine intake, e.g. excessive iodine supplementation, use of large quantities of iodine-containing medicines at one time or multiple times;

3. Mental stimulation or stress;

4. Certain viral and bacterial infections;

5. Smoking;

6. Pregnancy or childbirth;

These are important factors that can easily lead to thyroid disease, and if you can avoid them in your life, you should stay away from them. If you are unfortunate enough to suffer from thyroid disease, you don't need to worry too much, you should go to the hospital for checkups and deal with your condition in time. For thyroid patients, their daily diet is of particular concern, such as what can and cannot be eaten? Especially the daily food - radish and cabbage.

Should I eat less radish and cabbage for thyroid disease?

Both turnips and cabbage belong to the cruciferous family, and other members include cauliflower, cabbage, broccoli, and kale. These are extremely common foods, so why do some people say that you should eat less turnips and cabbage for thyroid disease? In fact, cruciferous plants have a class of antioxidant substances - thioglycosides, under certain conditions, thioglycosides will be hydrolyzed to generate isothiocyanate, and this substance can competitively inhibit the activity of iodine - sodium transporter (NIS), which inhibits iodine uptake by the thyroid gland, and in the long run, it will result in the body's impaired production of thyroid hormones, causing Thyroid enlargement.

In that case does a thyroid patient have to eat less radish and cabbage? This has to be analyzed on a case-by-case basis. If the patient eats a lot of cruciferous vegetables in a short period of time, e.g. 2 pounds of radish or cabbage a day, if he smokes a lot of cigarettes, if he is in a low iodine area and does not have access to seafood and iodized salt, or if he eats fruits that are rich in flavonoids (apples, pears, grapes, oranges), he should eat less radish and cabbage. In these cases, radishes and cabbage should be eaten sparingly, but if these conditions are not present, people with thyroid disease can eat cruciferous vegetables in moderation.

How to deal with thyroid disease

1. Correct understanding

First of all, you need to recognize the disease problem correctly, and it is better to learn more about the disease problem by yourself. You can ask your doctor or educate yourself from the internet to better cooperate with your doctor.

2. Maintaining optimism

Maintaining an optimistic state of mind will help the disease to recover. If the mood is uncertain, frequent tension, depression and anxiety may aggravate the disease.

3. Access to treatment

Thyroid diseases should be treated in a timely manner in a hospital, take medication regularly according to the doctor's instructions, have regular checkups, and do not believe in secret prescriptions.

The thyroid gland is the largest endocrine gland located in the front side of the neck of the human body. Clinically, abnormalities in the form or function of the thyroid gland can be manifested as thyroid diseases. The director of Thyroid Department of Guangzhou Xiejia Hospital pointed out that thyroid diseases can affect various organs and systems of the body and show different symptoms, which are introduced in detail below.

1, hyperthyroidism: hyper appetite, thinness, fear of heat, excessive sweating, panic, tachycardia, fatigue, agitation, insomnia, inattention and so on;.

2, hypothyroidism: fear of cold, fatigue, low sweat, loss of appetite, constipation, weight gain, forgetfulness, slow reaction, cold, dry and rough skin, calf muscle spasmodic pain and other systemic performance;

Thyroid nodules: the main manifestation is the appearance of nodules of different sizes and numbers on the anterior side of the neck, some of which can be felt, some of which can be seen, and which may even cause compression; and

Thyroiditis: Symptoms of thyroiditis vary from cause to cause. Acute cases may present as a sore throat and may be accompanied by symptoms of hyperthyroidism or hypothyroidism.

How can I prevent it?

Thyroid nodule patients can not eat radish because radish food contains thiourea goiter-causing substances, he can prevent the synthesis of thyroid hormones, causing goiter, so if there is a thyroid nodule, eating radish can aggravate the condition, forbidden to eat radish. Thyroid nodule is a common disease, if all the tests (blood test) are normal, then observe first, no need to rush treatment. It is suggested that you can check your blood if there is no hyperthyroidism or hypothyroidism, etc. You can eat non-iodized salt and reduce the intake of seafood and have regular checkups every year.

More attention should be paid to diet: three high, one avoidance and one moderation, referring to high-calorie, high-protein and high-vitamin diets, avoiding iodine diets, and moderately supplementing calcium and phosphorus.

1. Recommended food: According to your usual diet, you can choose all kinds of starch-containing food, such as rice, noodles, steamed buns, vermicelli, potatoes, pumpkin, etc.; all kinds of animal food, such as beef, pork, mutton, all kinds of fish, etc.; all kinds of fresh fruits and calcium-rich, phosphorus-rich food, such as milk, nuts, fresh fish. When low in potassium, you can choose more oranges, apples and so on.

2. Avoid choosing food: Avoid using iodine-containing food, such as kelp, seaweed, hairy vegetables, iodized salt and so on. Chinese medicines such as oysters, kombu, seaweed, Xiaku Cao, danshen, yuan ginseng, fragrant herbs, zhebei, etc. are also contraindicated.

3. pay attention to the sex of the food obscurantist function, from the point of view of Chinese medicine, food straight to choose to have nourishing Yin effect, such as turtles, soft-shelled turtle, water duck mother, etc., eat less warm, spicy and stimulating food.

The thyroid gland is located in the front side of the neck of the body's largest endocrine gland, clinically, regardless of the shape or function of the thyroid gland abnormalities are collectively referred to as thyroid disease, hyperthyroidism hypothyroidism thyroid nodules, if you go to the hospital after checking to confirm the condition of the doctor will be the first time to urge you not to eat radish and cabbage, this is why?

Any vegetable belonging to the cruciferous family is prohibited for thyroid patients, except for turnips and cabbages, which we eat most often. This is because cruciferous vegetables contain luteinizing hormone-like substances that have a pronounced enlarging effect on the thyroid gland, and turnips and cabbage also contain a substance called thiocyanic acid, which in many cases is associated with excessive intake of thyroid disease.

Therefore, if you have thyroid disease, you should reduce or even avoid foods containing thiocyanate. However, if people who live by the sea often consume foods containing high iodine content, they can eat more cruciferous vegetables to reduce the stimulation of the thyroid gland by high iodine content.

A: Some studies have shown that cruciferous vegetables, such as turnips and cabbage, should be avoided appropriately for thyroid disease

Remarks Description:

Cruciferous vegetables are a group of vegetables rich in thioglycosides, which under certain conditions can be hydrolyzed to produce isothiocyanates, which can impede the absorption and utilization of dietary iodine, affect thyroid precursor substances, and inhibit thyroid secretion. Cruciferous vegetables are a group of foods that includes, in addition to turnips, cabbage, kale, chard, and others. Depending on the type of thyroid disease, you can consult your primary care physician for specific questions.

Remind every friend: reasonable diet and good lifestyle can better help us to promote health enhancement, but any food and nutritional interventions can not replace the regular doctor's diagnosis and treatment and prescription recommendations, in order to ensure your health, remind all friends in any disease-related treatment and intervention, please go to the hospital to consult a professional doctor and dietitian! Wish you all good health!

We all know that thyroid disease and iodine intake have a strong relationship, but we don't realize that some of the vegetables that people see as healthy can also contribute to thyroid disease. Radish and cabbage are two of them, and for thyroid patients, eating radish and cabbage sparingly is a good idea.

Radish and cabbage both belong to the cruciferous family of plants, cruciferous, flavonoid food co-eating can lead to goiter, mainly because both cruciferous vegetables contain a common substance, that is, thiocyanic acid. Radish thiosulfin, found in radishes, also belongs to the isothiocyanate group. Some thyroid diseases are related to excessive intake of thiocyanate, and the mechanism is that the thioglucoside in food is metabolized to isothiocyanic acid and thiocyanate under the catalytic action of gastrointestinal bacteria, and thiocyanate and other substances. Thiocyanate-rich and flavonoid foods may directly affect the ultrastructure of the thyroid gland, thus affecting the thyroid's intake of iodine, and ultimately leading to abnormalities in the thyroid gland; these vegetables also have the potential to influence the metabolism and absorption of iodine in the intestinal tract These vegetables may also affect the metabolism and absorption of iodine in the intestines, making the amount of iodine in the thyroid gland to play an effective role is not enough, leading to the synthesis of the relevant hormones abnormally, resulting in abnormalities in the thyroid generation. In recent years, due to the thiocyanate, isothiocyanate, flavonoids phytochemicals with antioxidant, anti-aging, anti-tumor effects are widely used in food additives, pharmaceuticals and health care products and other industries, which are closely related to the high incidence of thyroid disease. And the consumption of radish and cabbage can aggravate the disease. To put it plainly, radish and cabbage contain a substance called thiocyanic acid, and this substance has an effect on the thyroid gland's iodine intake, and abnormal iodine absorption leads to thyroid disease. Therefore, thyroid patients should consume radish and cabbage sparingly.

I did some digging for this question and found out that there are some reasons for this.

Radishes and cabbage share a common characteristic, which is botanically known as "cruciferous".

What does it mean? It means that the blooms look like this:

And then there's this:

Guess you can see it already - the flowers that bloom are cross-shaped!

So are there any other crucifers besides turnips and cabbages? There are, too.

For example, cabbage and cauliflower and cabbage, greens and bok choy and broccoli, white radishes and carrots and green radishes, mustard and horseradish and blueberries, all of these.

So why does thyroid disease have to die with the cruciferous family of plants? What kind of spirit is that? The spirit of national security?

Not really ...... The real reason is:They have thioglycosides。

Thioglycosides are an antioxidant substance unique to the Cruciferae family, and this can be hydrolyzed into isothiocyanate, which is a chemical that can lead to goiter because it inhibits iodine uptake by the thyroid gland, leading to lower concentrations of thyroxine (T4), and as a final result, goiter.

This effect only occurs at relatively high plasma thiocyanate concentrations (concentrations of 4.8-6.4 mg/L are required), and in fact most regional populations have thiocyanate concentrations well below this range. Some populations in iodine-deficient areas (iodine intake less than 100ug/day) have low thiocyanate/iodine (SCN/I) excretion, and such low excretion ratios can lead to higher thyroid-stimulating hormone (TSH) levels and lower thyroxine (T4) concentrations.

That's why they say, "Eat fewer turnips and cabbages".

The world is full of delicious food, why do you have to stick to cruciferous flowers? Each has his own favorite turnip and cabbage, but in addition to turnips and cabbages, there are still large areas waiting for you to eat ah right!

Thanks for the invite.

Curious as to why someone would ask this question, I checked the relevant information, which probably means that vegetables such as turnip and cabbage produce a kind of thiocyanic acid after entering the human body, which inhibits the function of the thyroid gland to synthesize thyroxine, thus causing goiter.

The Internal Medicine book originally stated that common goiter-causing foods are cabbage, soybeans, bok choy, radishes, millet, and water containing too much calcium or fluoride. The goiter is caused by the presence of substances that cause goiter or block TH synthesis.

However, it is also said that long-term consumption of these foods in large quantities may develop thyroid disorders, exactly how much is considered a large quantity is not known. But from the results of the inverse, daily diet should not be a big problem, you think so many people eat so many years of turnip cabbage, get thyroid problems or a minority of people, is a combination of factors. The average person has nothing to worry about, and even those with thyroid problems have no problem consuming it in moderation, and to paraphrase, talking about side effects without talking about dosage is all hooliganism.

Likes are an encouragement
