Iodized salt is just a solution to prevent iodine deficiency. If you take the daily iodine intake sufficient from food, you might not need iodized salt. What are the benefits of iodized salt? Iodized salt:. Both iodized salt and non-iodized salt look the same, taste the same, and feel the same.
Then, what is non iodized salt? Non-iodized salt is salt without the addition of iodine. It consists of sodium and chloride. Still, table salt is processed after being harvested. During this process, some additives and anti-caking agents such as sodium aluminosilicate, silicon dioxide, and magnesium carbonate can be added to the table salt.
So, even if iodine is not added to it, other agents that enhance the taste and elongate shelf life might be included in the production.
Do you know how to identify salt? Iodized salt consists of iodate in it as well as some anti-caking agents and some dextrose.
These additives are necessary for iodized salt because they prevent the potassium iodide from evaporating and clumping. You can use one instead of another and achieve the same flavor. However, when we talk about non-iodized salts, there is a wide range of salt types we can include such as pink Himalayan salt, pickling salt, and kosher salt.
Table salt is commonly fortified with iodine, which is important for thyroid health. Sea salt is a general term for salt produced by evaporation of ocean water or water from saltwater lakes. It is less processed than table salt and retains trace minerals. These minerals add flavor and color. Sea salt is available as fine grains or crystals. Sea salt is often promoted as being healthier than table salt. But sea salt and table salt have the same basic nutritional value.
Sea salt and table salt contain comparable amounts of sodium by weight. Whichever type of salt you enjoy, do so in moderation. The Dietary Guidelines for Americans recommend limiting sodium to less than 2, milligrams a day. That's roughly how much sodium is in 1 teaspoon of table salt. Katherine Zeratsky, R.

It is a universal foodstuff, intake is seasonally consistent, costs are relatively small, and it is easily distributed [ 18 ]. Approximately countries, including Canada and some parts of Mexico, have adopted mandatory iodization of all food-grade salt [ 5 ], although the extent of implementation efforts in individual countries is unknown.
In contrast, fortification of salt with iodine in the U. Furthermore, it is assumed that the majority of salt consumption in the U. Although iodized salt in the U. Iodine is required for normal brain myelination in utero and during the early post-partum period.
As such, the developing fetus and infant are particularly vulnerable to the effects of inadequate iodine nutrition. Prenatal and other multivitamins marketed in the U. Data from the U.
National Health and Nutrition Examination Survey — demonstrated that only A recent survey of prenatal multivitamins available in the U. Levels of urinary iodine cannot be used to determine iodine status in an individual, given the day-to-day variation in dietary iodine intake. Median urinary iodine levels are used instead and reflect dietary iodine sufficiency across populations [ 5 ]. Subsequent studies have shown that this decrease has stabilized [ 25 , 26 , 27 ], although some subsets of the population, in particular pregnant women and women of childbearing age, may be at risk for mild to moderate iodine deficiency.
Iodine deficiency remains one of the most important public health issues globally, and an estimated 2. In , the United Nations World Summit for Children set forth the goal of eliminating iodine deficiency worldwide [ 29 ], and considerable progress has since been achieved.
Other groups which have been instrumental in advocating for improved iodine nutrition have been Kiwanis International and the U. Center for Disease Control [ 16 ]. A public health approach has been used to help ensure adequate iodine intake in U. The U. National Academy of Sciences also advocates that iodine be included in all prenatal multivitamins [ 33 ]. Following the successful implementation of salt iodization program in Switzerland, the introduction of iodized table salt in the U.
However, although recent national studies demonstrate that the general population is overall iodine sufficient, salt iodization in the U. National Center for Biotechnology Information , U.

Keywords: history, iodine, supplementation. Importance of Adequate Iodine Nutrition Adequate levels of iodine, a trace element variably distributed on the earth and found mostly in the soil and water of coastal areas, are required for the synthesis of the thyroid hormones, thyroxine T4 and triiodothyronine T3 , which play key roles in the metabolic processes of vertebrate life.
