1. Rock salt in the mine hasn't iodine. 2. Iodized table salt has 20+/-5 mg iodine/kg of salt, as potassium iodide or iodate.
Himalayan salt contains very small amounts of iodine, significantly less than iodized table salt. It is not a reliable source of iodine and should not be used as the sole source of this essential nutrient in the diet. It is recommended to consume other iodine-rich foods, or use iodized salt for adequate iodine intake.
Pink Himalayan salt typically contains very small amounts of iodine, much lower than what is found in iodized table salt. If you rely on salt as your main source of iodine, it is advisable to choose iodized table salt or ensure you get iodine from other sources in your diet.
It is difficult to provide an exact conversion as the iodine content in iodized salt varies. However, as a general estimate, you would need around 1 tablespoon of iodized salt to match the iodine content of 1 cup of rock salt.
I am not sure how much, but they DO contain iodine and you should avoid them if you are liable to retain water .
Iodized salt is good for the health only of persons who would otherwise have a deficiency of salt or of iodine in the their diet. Iodine deficiency can lead to the disease named "goiter". Some salt is necessary to life, but American diets often include so much salt that health is adversely affected by most of it.
You can't really get too much iodide from iodized salt, if that's what you're getting at. The only thing you can get is too much sodium. The advantage is that we all need a little iodide in our diets, and there are few sources to get it, and table salt is used so much that it's a handy place to get it from. Iodide prevents goiter. The other disadvantage is that it's terrible for canning and pickling. You need pure salt for that (check the label, even non-iodized salt has an agent to make it pour freely in humid climates, called prussiate of sodium, and a tiny tiny amount of sugar, .004%, about 1 tablespoon per bushel, to keep the potassium iodide stable and not turn into iodine). For canning and pickling, you need salt that contains nothing but salt. Anything else will make the final product cloudy. "Potassium iodide Potassium iodide is added as a nutrient, to prevent goiter, a thyroid gland problem caused by lack of iodine, and to prevent mental retardation associated with iodine deficiency. A project started by the Michigan State Medical Society in 1924 promoted the addition of iodine to table salt, and by the mid 1950's, three quarters of U.S. households used only iodized salt. Potassium iodide makes up 0.06% to 0.01% of table salt by weight. Sometimes cuprous iodide (iodide of copper) is used as the source of iodine.
Spirulina can contain large amounts of iodine. Iodine is fuel for the thyroid. Eating too much iodine is similar to pouring gasoline on a fire.
There is no iodine present in sodium. Iodine and sodium are different elements with distinct chemical properties.
Table salt typically contains iodine in the form of iodide at a concentration of about 0.006%-0.01% by weight. This is done to help prevent iodine deficiency, which can lead to thyroid issues.
If you have a hyperthyroid condition such as Graves Disease you must be mindful of how much iodine you ingest. As most salt used to cook or made available to you restaurants will be iodized it is best to avoid salty foods.
An enlargement of the thyroid gland that results from a deficiency of dietary iodine is called a goiter. A goiter is inflammation of the thyroid gland. Worldwide, the most common cause of a goiter is due to a lack of iodine in our daily diet.
