Table salt refers to sea salt, well salt, mineral salt, lake salt, earth salt and so on. They are mainly composed of sodium chloride, and the content of sodium chloride in well salt and mineral salt shall not be less than 95% according to the national regulations. Salt contains barium salt, chloride, magnesium, lead, arsenic, zinc, sulfate and other impurities. We stipulate that barium content should not exceed 20mg / kg. Too much magnesium and calcium in salt can make the salt bitter, too high fluoride can also cause poisoning. In recent years, many experiments have confirmed that salt intake is related to the incidence rate of hypertension. Excessive intake of salt in diet can cause hypertension. The World Health Organization (who) suggests that the intake of less than 5g salt per person per day can prevent coronary heart disease and hypertension. In China, it is stipulated that the daily intake of 7 g salt can meet the body's need for sodium.
Salt is essential for every family. People can't help but eat salt. Although we advocate eating less salt, it is for health. However, a large number of industrial salt has been processed and packaged into "edible salt", which is used by illegal traders to make huge profits. This kind of salt is extremely harmful. Iodine deficient salt will affect human metabolism, damage nervous system and intelligence development.
