Less Sodium, more Iodine, and other things brands claim
Iodised salt is common edible salt to which a very small quantity of an iodine compound has been added. Iodised salt is used to prevent a health problem now known as iodine deficiency disorder (IDD). Iodine is a natural element that is essential to human life. Some of the most vital functions of the human body – such as proper development of brain and body and maintenance of body temperature – depend upon a steady supply of iodine. With regard to India, regulations require the iodine content to be not less than a certain amount in food-grade iodised salt. The techniques for iodisation are simple and well established. The added iodine does not affect the appearance or taste of salt, which happens to be one of the oldest, most ubiquitous food seasonings in the world. However, as the results of Consumer Voice’s tests on 14 brands of iodised salt show, adherence to the national standards on quality and acceptability parameters is not uniform. As is mostly the case, the tests threw up mixed results. For instance, while two ISI-marked brands failed to meet the requirement for moisture, two proprietary brands did not match up to their claims for less sodium. The detailed findings and analysis follow. A Consumer Voice Report
As per our standard procedure, we undertook market research to identify the popular and regular-selling brands of iodised salt across the country. All the brands selected for testing were evaluated and graded as per their overall performance based on the comprehensive laboratory results. The grading has been done based on the international grading system. Two brands, Saffola (Less Sodium) and Tata Salt Lite (Low Sodium), claim to be proprietary – this means FSS Regulations and relevant Indian Standards are not applicable. There are no specifications for low-sodium salt in the national standards. The key parameters for which the samples were tested included sodium and iodine content, water insoluble matter, moisture, alkalinity and particle size. We also conducted tests for presence of heavy metals (lead and arsenic).
The ‘Iodine’ in Salt
Iodine is a trace mineral that makes thyroid hormones, which are essential for normal growth and development of human body. About 70–80 per cent of iodine is found in the thyroid gland in the neck and the rest is distributed throughout the body, particularly in the muscles and blood. If our body does not have enough iodine, hypothyroidism – low thyroid hormone levels – can develop. Symptoms of hypothyroidism include sluggishness or fatigue, weight gain, dry skin, and sensitivity to temperature changes. In infants and children, hypothyroidism can affect physical and mental development. Some people with hypothyroidism develop an extremely large thyroid, known as goitre. Deficiency of iodine can cause diseases like mental retardation, goitre and cretinism. In fact, without enough iodine a newborn’s brain and body can become permanently retarded and stunted. Iodine is vitally needed during early childhood, puberty, pregnancy and lactation. A woman who is deficient in iodine is likely to produce an abnormal child. If left untreated, the child’s mental and physical condition worsens as s/he grows older.
Too Much Salt?Being the main source of sodium, a small amount of salt is important for good health. It helps in maintaining the correct volume of circulating blood and tissue fluids in the body. But when consumed in large amounts, salt makes this ‘correct volume’ its first victim. When the salt levels are too high in the body, kidneys cannot keep up and let salt enter one’s bloodstream and creates hypertension in the body. Too much salt in the blood also causes water retention as salt draws more water into the blood. This further raises the blood pressure. World Health Organization (WHO) recommends less than five grams (about one teaspoon) of salt per person per day. Remember that many processed and convenience foods, preserved foods, and sun-dried foods as well as canned foods contribute to higher intakes of salt.

Low-sodium salt is a specially formulated salt that provides lower sodium than ordinary salt by partial replacement of sodium chloride with potassium, magnesium and calcium compounds. It is generally consumed by people with symptoms of hypertension and high blood pressure.
