The average daily salt intake of urban residents in China is 1 1g, and that of rural residents is 10g. This means that most iodized salt in the market contains 20-50 micrograms of iodine per gram, and the daily iodine intake of China people has reached an astonishing 220-850 micrograms, far exceeding the "safety line" of 200 micrograms per day designated by the World Health Organization. Iodine intake has two sides, and it is not good to supplement iodine too much. In order to control the excessive intake of iodine, we should eat non-iodized salt. ?
Many people have complained that it is getting harder and harder to buy non-iodized salt now, and they have traveled all over the supermarkets and shops in the city, but they just can't buy non-iodized salt. Non-iodized salt has been sold in high iodine areas in China.
Matters needing attention in choosing edible salt
The edible salt in the market is classified according to the quality grade, which is generally divided into excellent grade, first grade and second grade. Choose top-grade and first-grade edible salt when buying. The whiteness and granularity of these grades of salt are better than those of secondary salt, which can add better taste to our dishes. When buying edible salt, you need to pay attention to the production standard number on the packaging bag. Salt without production standard number may be fake and shoddy products, so avoid buying it.
The ingredient list of edible salt is usually very simple, which mainly contains sodium chloride, potassium iodate and water. When buying salt, you can carefully read the ingredient list on the back of the package to ensure that you choose the salt that suits you.
