Man has used salt for many years for a variety of things, including preserving food for a longer period of time. But in recent decades, its excessive intake has led to a number of diseases, including kidney and hypertension issues. 

Even a novel salt for hypertensives was developed with the intention of lessening this harm. Since the meal is manufactured with a high concentration of iodine, regular salt consumption is also essential for health. 

As a result, a frequently asked question is whether salt devoid of iodine is dangerous and why it is used for.

Why is it important to consume iodine?

Iodine is a micronutrient important for the growth and operation of the body. It is used to create the hormones thyroxine (T3) and triiodothyronine in the thyroid gland, which is located near the front of the neck (T4). 

These hormones, in turn, are in charge of sustaining the flow of energy, which is necessary for the proper operation of important organs and the preservation of body heat, as well as for physical development and neurological growth. 

The maximum permitted iodine level for salt intended for human consumption is 45 milligrammes per kilogramme, with a requirement that it be at least 15 milligrammes high. 

The National Health Surveillance Agency also states that the World Health Organization’s (WHO) guidelines are followed by the countries government’s control of salt iodization.

What conditions might an iodine deficiency lead to?

Table salt must be iodinated, even though iodine deficiency illnesses are uncommon. But in some nations, the number of people experiencing irreversible harm from a shortage of iodine in the body is alarmingly high.

Infantile cretinism, characterised by severe and irreversible mental retardation, congenital abnormalities, deaf-muteness, and goitre are a few of the diseases brought on by a lack of this micronutrient.

Goitre is one of the most visibly apparent clinical manifestations of DDI, where the thyroid gland enlarges and forms a kind of nodule at the front base of the neck that can cause coughing spells and, less frequently, a

Adults who are not pregnant should consume about 150 micrograms daily. 90 mcg must be consumed daily by children ages 1 to 8, 120 mcg from ages 9 to 13, and 150 mcg after the age of 14.
