How can I get thyroid nodules if I never eat seafood?

As we all know, iodine and the thyroid gland have a special relationship. Therefore, many patients with thyroid diseases are afraid of the word "iodine". When many people are diagnosed with thyroid nodules, their first reaction is that they eat too much seafood. In fact, this may "wrongly" blame seafood. The causes of thyroid nodules are very complicated, and the influence of diet is only part of it. On the other hand, the influence of food on the thyroid gland mainly refers to the influence of "iodine-rich food" on the thyroid gland, not just seafood, so this pot cannot be simply thrown to seafood.

Some seasonings, pickled processed foods, and eggs also contain a lot of iodine. The following foods are high in iodine:

Algae - Highest iodine content

Including kelp, laver, wakame, hair algae, etc. It is the food with the highest iodine content in the seafood family. For example, every 100 grams of dried kelp contains up to 36240μg of iodine, ranking first among iodine-containing foods.

Iodized salt and chicken stock - seasonings containing iodine

The average iodine content of iodized salt in my country is about 2000-3000 μg per 100 grams. The iodine content in chicken essence is also very high, about 766 μg per 100 grams.

Fish, shrimp, crab and shellfish - higher iodine content after drying

Fish, shrimp, crab and shellfish, such as dried shrimp 983g/100g, ark shell 162g/100g, flower crab 45.4g/100g and hairtail 40.8g/100g.

Pickled foods - the content will increase after adding iodized salt

Ham, salted fish, bacon, Chinese sausage, dried bean curd or canned food... these things are indeed delicious, but they are generally added with a lot of iodized salt, so the iodine content is certainly not low. For example, shrimp paste contains about 166.6μg of iodine per 100g; Cantonese sausage contains about 91.6μg of iodine per 100g; and dried bean curd contains 46.2μg/100g of iodine.

Eggs —An Unexpected Food Containing Iodine

Unexpectedly, the eggs we love also contain a lot of iodine (mainly concentrated in the yolk). Among them, quail eggs have the highest iodine content (233μg/100g), followed by goose eggs (59.7μg/100g). Duck eggs contain 34.2μg/100g, and chicken eggs are relatively low, at about 22.5μg/100g.

In addition, there are many factors that cause thyroid nodules. Clinical studies believe that they may be related to individual differences in patients, environmental factors, autoimmunity, genetic factors, iodine intake, abnormal glucose metabolism, emotional state, work pressure, etc. It is more important for patients with thyroid nodules to maintain a reasonable diet, a good mood, and ensure sleep.
