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.
There are 16 Tablespoons in a cup regarless of what is being measured.
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.
None, sodium does not contain iodine or any other element apart from itself..
Omega-3 are a group of unsaturated fatty acids; they don't contain iodine.
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.
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.
Iodine is an important part of our daily diet. This element is essential for good thyroid health because it is needed for the production of thyroid hormone. Iodine is found in various foods such as cheese, fish, cows milk, yogurt, and without it can cause enlargement of the thyroid gland or hypothyroidism.In the United States, the recommendations are as follows courtesy of the American Thyroid Association:"The Institute of Medicine has set the Recommended Dietary Allowance (RDA) for iodine in adult men and women at 150 μg per day. Individuals who add tablet salt to their food regularly should use iodized salt. One teaspoon of iodized salt contains approximately 400 μg iodine. Most iodine-containing multivitamins have at least 150 μg iodine, but only about half of the types of multivitamins in the U.S. contain iodine.The RDA is 220 μg iodine per day for pregnant women and 290 μg iodine per day for breastfeeding women. Because the effects of iodine deficiency are most severe in pregnant women and their babies, the American Thyroid Association has recommended that all pregnant and breastfeeding women in the U.S. and Canada take a prenatal multivitamin containing 150 μg iodine per day."
iodine got its name because when bernard courtois was making saltpeter he added too much acid and a violet puff went into the air and iodine came from the latin word ioeides which means violet in english.
