There is a class of nutrient-dense vegetables that, if consumed in excess, can harm our thyroid gland. So what kind of vegetable is this?And how does it affect our thyroid function?How do we know if the thyroid gland is damaged?What is the safest way to consume it?Hello everyone, I am nutritionist Wang Yan, health is our greatest wealth, let's manage it together. 
The reason why we should pay attention to the health of the thyroid gland is because the thyroid gland is a very important endocrine gland in the human body. Its task is to make thyroxine, a hormone secreted into the bloodstream that is transported to tissues and cells throughout the body, helping the body use energy, maintain body temperature, and allow the brain, heart, muscles, and all other organs to function properly. In the human body, too much or too little thyroxine can lead to serious health problems. Therefore, when God created human beings, he arranged an organ that balances the regulation of thyroxine, that is, the pituitary gland, which is located at the base of the brain, and it secretes a hormone that stimulates the thyroid gland to produce thyroxine. This hormone is called thyroid-stimulating hormone. If there is too much thyroxine, it decreases secretion;If thyroxine is too low, it increases secretion to maintain a steady state of thyroxine in the body.
If the thyroid gland is a heater, then the pituitary gland is a thermostat. The hormone secreted by the thyroid gland is called thyroxine, also known as T4, and it contains four iodine atoms. When it removes one iodine atom, it becomes triiodothyroxine, also known as T3. The body has a greater need for T3, especially our brain. Therefore, iodine atoms are a key factor in the formation of thyroxine, which cannot be produced in the body and must be ingested from food.
So which foods are rich in iodine?Read on. About 80% of our body's iodine is used by the thyroid gland. If we are iodine deficient, there will be problems with thyroid function. So how do you know if something is wrong with your thyroid gland?
Thyroxine regulates our body temperature, metabolism and body energy**. If you have symptoms such as chronic fatigue, weight gain, cold intolerance, low body temperature, thinning and brittle hair, constipation, etc., regardless of whether the blood test is within the so-called normal range, you may have a hypothyroid, and some people will have lumps and nodules in their thyroid gland.
When our body temperature is 1 degree higher, it will be very uncomfortable, which is called a low-grade fever. In fact, 1 degree lower is just as uncomfortable, but we often overlook it. More seriously, if iodine deficiency leads to hypothyroidism, it will stimulate the pituitary gland to secrete a large amount of thyroid-stimulating hormone, and it will also stimulate thyroid cell proliferation, produce nodules, and even induce thyroid cancer.
So why do you feel uncomfortable eating vegetables like broccoli that are very healthy? Herein lies the problem, cruciferous vegetables all contain glucosinolated glucosinolate, which is metabolized into thiocyanate. These compounds affect iodine transport and the binding of iodide to thyroid proteins. Hypothyroidism increases the secretion of thyroid-stimulating hormone and stimulates thyroid cell proliferation, which has been found in animal experiments to induce thyroid cancer.
Studies have found that women in Melalicia are generally deficient in iodine, they have a particularly high consumption of cruciferous vegetables, and the incidence of thyroid cancer is also high. So what are the cruciferous vegetables? In addition to broccoli, there are also cauliflower, cabbage, broccoli, mustard greens, turnips, and kale, among others. These are very nutritious vegetables, and they contain a lot of fiber, various vitamins, and minerals.
So can't we eat these vegetables? Of course not, how can we use these nutritious vegetables safely and effectively? There are three things to do: First, make sure your body has enough iodine. What foods can provide us with this protection? Cheese, milk, yogurt, eggs, iodine-containing multivitamins, iodized salt, saltwater fish, seaweed, kelp, seaweed, etc., and shellfish.
Second, don't eat it raw, cook it or steam it, so that the damage to iodine utilization will be much less. Third, don't eat too much. A study from Oregon State University found that consuming 150 grams of cooked Brussels sprouts daily for four weeks had no adverse effects on thyroid function. Therefore, everyone should not eat more than a small bowl of cooked cruciferous vegetables every day.
Speaking of which, do you feel tired of living? There are many things that cannot be eaten less, nor can they be eaten more, let alone eaten in the wrong way. If you like my channel, please like, ** and subscribe, I am nutritionist Wang Yan, guarding health, we will see you in the next episode.
