Is Iodised salt harmful to body?

Answer 1

No Iodised salt is produced so that there is a source of iodine to the body, in places like Australia and New Zealand where there is a lack of iodine in the natural surroundings where they would otherwise be taken up with fruit and vegetables.

Iodised salt (also spelled iodized salt) is table salt mixed with a minute amount of various iodine-containing salts. The ingestion of iodide prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of mental retardation.[1] It also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by iodisation of salt.

Iodine is a micronutrient that is naturally present in the food supply in many regions. However, where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables, iodine added to salt provides the small but essential amount needed by humans.(source wikipedia)
