Iodine is one of the essential elements for our human body. Although its content is very low, if it is lacking, it may cause other diseases. The impact of iodine on human intelligence is very direct and has significant effects. In daily life, we mainly rely on consuming iodized salt to absorb iodine, in addition to also absorbing it from food. So, what are the foods that contain iodine?
What are the foods containing 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.
