Why is it important to include iodized salt in one’s diet? |
Iodized salt provides an adequate supply of iodine in the diet, a necessary element for the production of thyroid hormones. A quarter teaspoon of salt (1.5 grams) provides 67 micrograms of iodine, which is about half of the U.S. Recommended Daily Allowance of 150 micrograms per day for adults.
The thyroid produces the hormones T3 and T4.When these levels are too low, the pituitary gland creates more of the hormone TSH, and when T3 and T4 are too high, the pituitary makes less TSH. Doctors can measure TSH to find out the health of the thyroid. Anatomical Chart Co.
