European nutritionist Most hyperthyroidism patients know to avoid taking too much iodine, and probably know that kelp, various seafood and deep-sea fish are all foods with high iodine content, but if you search for relevant health education materials on the Internet, you will find that milk and dairy products are also among the foods with high iodine content. Why are milk and dairy products high in iodine? Where does iodine come from? Can hyperthyroidism patients really not drink milk? Let the nutritionist answer your questions this time! Where does iodine in food come from? How much iodine do we eat a day? Iodine is a trace element. Non-radioactive iodine is scattered all over nature, and the biggest source is the ocean. After iodine enters the atmospheric circulation, it will combine with water and other particles and further penetrate into soil and surface water, and will also be absorbed by plants growing in it. Therefore, when we eat vegetables and fruits, we can get trace amounts of iodine, among which the best sources are kelp, seaweed and other ingredients, as well as refined salt fortified with iodine. The data show that there is about1.5 ~ 20mg of iodine in healthy adults, of which 80% is in the thyroid gland. When the iodine intake is too high, healthy people can regulate the iodine concentration through urine excretion, but for those patients with autoimmune antibodies or poor tolerance to high iodine, it may cause hyperthyroidism and other problems, and at this time, iodine restriction diet may be adopted. The low iodine diet for hyperthyroidism is less than 50 micrograms per day, which is a very strict amount. However, the treatment of hyperthyroidism is different from the course of disease. Not every patient needs to eat a low iodine diet. Some patients only need to limit iodine for a short time during the treatment. If iodine is limited rashly, hypothyroidism may occur. Therefore, it is recommended to ask the doctor whether it is necessary to limit iodine so strictly.

What is the actual situation in Taiwan Province Province? According to the official website, the Agriculture Committee of the Executive Yuan and other dairy producers, at present, you will still use excellent iodine to clean cattle. Some milk is wiped by agriculture, while others are soaked. Therefore, the difference of contact time and dose is debatable for the actual iodine content in milk. In addition, some books related to livestock products mentioned that in addition to iodine solution, there are bromogeramine (benzyl ammonium bromide), sodium hypochlorite and chlorhexidine, all of which do not contain iodine. Although there is no data of food iodine content in Taiwan Province food nutrition database at present, the Department of Nutrition Science of Fu Jen Catholic University analyzed the iodine content of dairy products in Taiwan Province Province in 20 14. The results show that the iodine content of liquid dairy products in the market is 52 to 125 micrograms per liter of fresh milk (including full fat, low fat and defatted milk), 8 to 67 micrograms of flavored milk, and 36 to 165433. After conversion, the equivalent of a cup of 240 ml of fresh milk contains only 12 to 30 micrograms of iodine. If you take 1.5 to 2 cups according to the daily dietary guidelines, you can only get 60 micrograms at most, which has not reached the recommended intake of iodine 150 micrograms. In addition, the study found that patients with hyperthyroidism may lose bone metabolism because of excessive thyroxine secretion before diagnosis, and the loss of bone mineral density will occur faster and earlier than that of healthy people. If the best sources of calcium are limited in the diet: milk and dairy products, the risk of osteoporosis will increase. Judging from the contents of calcium and iodine, milk is not a completely untouchable food for hyperthyroidism patients. The key point is that patients who are limiting iodine should pay more attention to whether they eat iodized salt, kelp or seaweed. Therefore, nutritionists still suggest that milk and its products can be ingested in moderation to avoid calcium deficiency. Finally, once again remind everyone that if you suspect that you have thyroid function problems, you still need to see a doctor at the first time and receive routine treatment. At the same time, consult with doctors and nutritionists to find out what you need to pay attention to in your diet. Never limit or increase the iodine intake in the diet by yourself, so as not to aggravate the symptoms.
