The trace element iodine has important functions in the body – and both too little and too much can have unpleasant consequences. Read here how healthy iodine is and which foods are high in iodine.
Info and list: Iodine in food
Trace elements and minerals are involved in numerous vital processes in the body and a permanently inadequate supply often has serious health effects. Iodine, for example, contributes to the normal functioning of the thyroid gland, cognitive function, energy metabolism, the nervous system, and the skin. Five more than good reasons to keep an eye on the iodine content in food. In addition, the diet during pregnancy should contain sufficient amounts of the trace element, because iodine is important for the growth of the child. On the other hand, people who suffer from Hashimoto’s chronic thyroid inflammation must ensure that their food contains little iodine. Either way, it is good to know the suppliers of the trace element.
Ingest iodine: the best foods
Iodine is generally contained in animal and vegetable foods. Good sources include:
- iodized salt
- seafood
- sea fish
- algae
- Cheese
The problem with this: The iodine content in milk and thus also in cheese varies greatly from region to region. Products from mountain regions in particular naturally contain little iodine. Due to the overall insufficient iodine supply in Germany, many products are therefore enriched with the trace element. A look at the list of ingredients provides information. During pregnancy, foods with iodine may not be sufficient to meet the requirement. In this case, supplementation is sometimes useful. Vegans may also consider a supplement in consultation with a doctor.
You should pay close attention to the iodine content of these foods
If you want to find out more about the iodine content in certain products, you will find comprehensive tables of iodine-containing foods in nutrient databases on the Internet. In particular, professional associations for thyroid diseases publish such detailed lists. Healthy people can also use these to fine-tune their care. For example, vegan iodine foods are interesting for people who eat no animal products. Algae, for example, are a rich source. Incidentally, caution is advised with dietary supplements: the iodine content of tablets with Spirulina, Chlorella & Co. is often far too high.
