In vertebrate biology, iodine's primary function is as a constituent of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3). These molecules are made from addition-condensation products of the amino acid tyrosine, and are stored prior to release in an iodine-containing protein called thyroglobulin.
Natural food sources of iodine include seafood which contains fish, seaweeds, kelp, shellfish and other foods which contain dairy products, eggs, meats, vegetables, so long as the animals ate iodine richly, and the plants are grown on iodine-rich soil. [114] [115] Iodised salt is fortified with potassium iodate, a salt of iodine, potassium, oxygen.
Many plants have adapted to iodine-deficient terrestrial environment by removing iodine from their metabolism, in fact iodine is essential only for animal cells. [7] An important antiparasitic action is caused by the block of the transport of iodide of animal cells inhibiting sodium-iodide symporter (NIS).
If you are following a low iodine diet, always verify on the label that the salt does not contain iodine. Simply Recipes / Getty Images When To Use Kosher Salt vs. Table Salt
Iodine rarely occurs naturally in mineral form, so it comprises a very small portion of rocks by mass. [2] Sedimentary rocks have higher concentrations of iodine compared to metamorphic and igneous rocks. [4] Due to the low concentration of iodine in rocks, weathering is a minor flux of iodine to soils and the freshwater hydrosphere. [1]
Plant-based milks are also lower in calories and saturated fat compared to animal milk; the brand of oat milk that we looked at had 0 grams of saturated fat (and just 1.5 grams of total fat) and ...
Typically made by mining underground salt deposits, this type of salt is processed and refined to remove minerals and impurities, then fortified with anti-caking agents (such as silicon dioxide ...
Vegan diets typically require special attention for iodine, for which the only substantial and reliable vegan sources are sea vegetables, iodized salt and supplements. The iodine content of sea vegetables varies widely and may provide more than the recommended upper limit of iodine intake. [1]
