IODIZED SALT

           IODIZED SALT 

                 ****

Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting, brining, and pickling are also ancient and important methods of food preservation.

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about 35 g  of solids per liter of sea water,

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. The greatest single use for salt (sodium chloride) is as a feedstock for the production of chemicals.  It is used to produce caustic soda and chlorine; it is also used in the manufacturing processes of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around three hundred million tonnes of salt, only a small percentage is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods.

Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute.Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. The World Health Organization recommends that adults consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

How much IODINE required 

        **********

The amount of iodine and the specific iodine compound added to salt varies.  Food and Drug Administration (FDA) recommends 150 micrograms of iodine per day for both men and women.

Current dietary guidelines recommend that men and women ages 19 and older get 150 micrograms of iodine a day. Women who are pregnant should get 220 micrograms, and women who are breast-feeding an infant should get 290 micrograms.

Table salt is made up of just under 40% sodium by weight, so a 6 g serving (1 teaspoon) contains about 2,400 mg of sodium. Sodium serves a vital purpose in the human body: via its role as an electrolyte, it helps nerves and muscles to function correctly, and it is one factor involved in the osmotic regulation of water content in body organs (fluid balance).

Because consuming too much sodium increases risk of cardiovascular diseases, Health organizations generally recommend that people reduce their dietary intake of salt. High sodium intake is associated with a greater risk of stroke, total cardiovascular disease and kidney disease.  A reduction in sodium intake by 1,000 mg per day may reduce cardiovascular disease.

The Difference Between Iodized Salt and Non-Iodized Salt. ........

Iodized salt is salt that contains small amounts of sodium iodide or potassium iodide. It's normal salt that has been sprayed with potassium iodate. It looks and tastes the same! The majority of table salt used nowadays is iodized, 

 Your body is unable to make iodine, yet it's important for a healthy thyroid and other body functions.

How much IODINE in percentage 

Potassium iodide (KI) is a salt composed of 76% of iodine and 23% of potassium which presents itself as transparent or white hexahedral crystals.

Adults need 140 micrograms (μg) of iodine a day. Most people should be able to get all the iodine they need by eating a varied and balanced diet.

What fruits and vegetables have iodine?.....

Fruits: Few fruits like Strawberries, Cranberries and Pineapple are an excellent and rich source of iodine. Beans: Green beans and navy beans

As a whole, tomato fruits resulted in being able to accumulate high amounts of iodine. 

Potatoes are a great source of iodine that is very commonly found and is cheap. When baked or cooked with its skin on a potato can supply you with 60/mcg of iodine.

 both are called for their high iodine content. Some portion of green beans included 3/mcg of iodine that caters to 2% of the required a quantity in the daily diet

What foods have iodine?

          ********

Iodine is found mainly in animal protein foods and sea vegetables, and to a lesser extent in fortified foods like breads, cereals, and milk.

• Seaweed (nori, kelp, kombu, wakame)

• Fish, shellfish (cod, canned tuna, oysters, shrimp)

• Table salts labeled “iodized”

• Dairy (milk, cheese, yogurt)

• Eggs.

• Beef liver.

• Chicken.

 Naturally high in iodine? .......

You can get recommended amounts of iodine by eating a variety of foods, including the following: Fish (such as cod and tuna), seaweed, shrimp, and other seafood, which are generally rich in iodine. Dairy products (such as milk, yogurt, and cheese) and eggs, which are also good sources of iodine.

High iodine intakes 

        ******

 some people, excess iodine intakes may precipitate hyperthyroidism, hypothyroidism, goiter, and/or thyroid autoimmunity.

find higher iodine levels are associated with lower motile sperm counts and more than 3 years of not achieving pregnancy among males .

Another research suggests that excessive iodine intake may be a potential cause for discontinuous decline in sperm counts

In iodine sufficient individuals, iodine excess causes elevated thyroid-stimulating hormone levels, which inhibits thyroid hormone production leading to hypothyroidism and goiter.

The use of high iodine concentration contrast media has recently been shown to improve conception rates in couples with unexplained infertility.

An increased risk of infertility was also observed if patients consumed too much iodine. During pregnancy, we see that patients who had a deficient intake of iodine were also at a greater risk of developing preeclampsia, preterm birth (before 37 weeks) and poor fetal growth.

Treatment of Iodine Excess .......

People with excess iodine are advised to use salt that is not fortified with iodine and to reduce their consumption of foods that contain iodine, such as seafood, seaweed, yogurt, and milk, and to avoid taking supplements containing iodine.

Which one  salt is good

          *******

Iodized salt contains 4% nutrition.

Rock salt contains 94 percent nutrition.

In India only people living on mountains.There is a deficiency of iodine.

Only 5% of the total population of our country lives in the mountains.

There is no iodine deficiency anywhere in the rest of the country.

Iodine is available in the fruits, vegetables and grains of our country.

which is easily available to us.So there is no question of iodine deficiency.

Then why so much promotion of iodized salt.Iodine excess.Making our youth impotent.Most of our body problems!

Due to excess of iodine in the body.There should not be excess of iodine in our body.We have to take care of ourselves.

         Thanks to all
