Because iodine, as an important nutrient in the human body, plays an important role in maintaining the health of the body. When iodine deficiency occurs in the body, it can cause a series of serious physiological injuries to people of different ages, some of which can be fatal.

Iodine is found in nature and is mainly ingested by people from drinking water, food, vegetables, and the surrounding environment.

1. Iodized salt has become a national policy, just like family planning. In fact, China should choose between two kinds of salt iodized or non-iodized salt. However, in many areas, there is only iodized salt, and even in the coastal area of Guangdong, there must be a lack of iodine in every place in China, and now there is more seafood, and there is basically no iodine deficiency in people's lives.

2. Safe and effective. The standard of iodine content in salt stipulated in China is not less than 40 mg per kilogram of iodized salt when processed and shipped, not less than 30 mg in the sales department, and not less than 20 mg in the user. Consumption of this iodized salt ensures the daily iodine requirement.

Human beings, regardless of race, ethnicity, age, and gender, must eat an appropriate amount of salt every day, so table salt is the best carrier for iodine supplementation.

By eating iodized salt, you can ensure the life, appropriate amount and durability of iodine supplementation.

The consumption of iodized salt is economical, and it only costs a small amount of money to solve the big problem of disease prevention, even for a very poor area or family. The above advantages determine that iodized salt is the best method among various iodine supplementation methods.
