Question

Iodine supplied by 10 g of iodized salt should be approximately__________ ?​

Answer 1

Answer:

Iodine supplied by 10 g of iodized salt should be approximately 150 micrograms.

Explanation:

Since 1984, government of India decided to iodize all forms of edible salts as per the universal salt iodization. Based on studies a generally accepted desirable dietary iodine intake by an adult is 100-300 micrograms/day. The average 10 g salt is consumed daily in India. Consumption levels are varied within the 5-15 g/day depending on children and adults. As per Government of India recommendations, a minimum of 150 micrograms of iodine per day should be consumed. Approximately 30% of iodine is lost during cooking from the average daily intake of 10 g iodine fortified salt containing 150 microgram of iodine. The remaining 105 micrograms is ingested and from this about 70% is absorbed by the body. This means approximately only 73.5 microgram is absorbed per day from iodine fortified salt. This daily consumed quantity of iodine when added and consumed through food will be broadly comparable to the daily physiological need of the body.

Answer 2

Answer:

Iodine is often added to table salt for preventing iodine deficiency. As, lack of iodine leads to problems in the thyroid gland. The common proportion is 15 parts per million, out which 10 g of salt should approximately have 150 mcg of iodine. When iodized salt is  consumed, it gets quickly absorbed by the duodenum and stomach.
