Many people overlook the supplementation of trace elements in the human body, such as iodine, which has a very direct and significant impact on human intelligence. Although in daily life, we mainly rely on consuming iodized salt to absorb iodine, we can also consciously obtain it from some foods. So, what foods contain iodine?
1. Seafood products
Marine organisms have a high iodine content. The food with the highest iodine content is seafood, such as seaweed, fresh hairtail, dried clams, dried clams, scallops, mussels, sea cucumbers, jellyfish, lobsters, etc.
Kelp has the highest iodine content, reaching over 240 milligrams per kilogram in dry kelp; The second highest concentration is around 800 micrograms per kilogram for shellfish and fresh sea fish. However, the iodine content in salt is extremely low, and the more refined the salt, the less iodine it contains. The iodine content in sea salt is about 20 micrograms per kilogram.
2. Land based food
Land based foods have the highest iodine content of 40 to 90 micrograms per kilogram in eggs and milk, followed by meat. Freshwater fish have lower iodine content than meat, while plants have the lowest iodine content, especially fruits and vegetables.
80% -90% of human iodine comes from food, 10% -20% is obtained through drinking water, and 5% of iodine comes from the air. Therefore, iodine in food is the main source of human iodine. Iodides in food can only be absorbed after being reduced to iodide ions, while iodine bound to amino acids can be directly absorbed.
3. Fruit
Fruits with extremely high iodine content include cherries, etc; Fruits with high iodine content include oranges, bananas (high in potassium), tomatoes, pineapples, peaches, apple sauce, and pickled/pickled fruits; Fruits with moderate iodine content include apples, lemons, watermelons, guavas, etc.
However, it should be noted that a lack of iodine is inevitably very harmful to the human body. However, excessive intake of iodine is also harmful and can cause diseases such as hyperthyroidism. So what we are doing is scientific iodine supplementation. If iodine deficiency is severe, we cannot blindly supplement iodine. We must supplement iodine under the guidance of a doctor.
