In sea water there are large reserves of iodine, so its inhabitants in their bodies accumulate a large amount of it.Shrimp, squid, crabs, mussels, oysters and scallops are not only tasty, but extremely useful.100 g of these specialties contain from 300 to 100 mcg of iodine.But, unfortunately, so replenish stocks of iodine can not everyone.

More iodine has sea fish stocks (from 190 to 50 micrograms), and freshwater, but also prone to heat treatment, is poor in this trace element – 5-10 mcg.

Iodine is found in foods that every day we include in their menu – it’s milk, eggs, butter, pork and beef, bread, cereals.

Also kelp, rich in iodine and salt-water fish. Heck, pollack, haddock, cod, bass, capelin, salmon, tuna and flounder contain from 160 to 50 micrograms of the trace element. Just 150 grams of hake able to meet the daily requirement of iodine.
