Therefore, in daily life, when we buy edible salt, we should pay attention to the product's name, place of production, production date, formula and shelf life, food or use methods. You should purchase the edible salt produced by the regular merchants, because the salt is made by advanced salt making process, refined through the process of dissolution, brine clarification, evaporation and drying, reducing the magnesium, tungsten and sulfate that are not beneficial to human health. The content of ions and other chemical substances, but also reduce the sediment and other impurities, with high content of sodium chloride, white, dry, sanitary, long release is not easy to dissolve and so on.

At present, there are many health-care salts on the market, such as low-sodium, high-potassium, selenium-enriched, and iodine-enriched salt. Because potassium maintains the body's water balance, maintains osmotic pressure and acid-base balance in the body, and counteracts the effects of salt increase and damage to blood vessels, it can prevent stroke attacks. Selenium has significant resistance to the toxicity of metallic cadmium, mercury and arsenic. It can prevent blood pressure and thrombosis in cardiovascular disease and has a certain health effect on the heart. Iodine exerts biological effects through the formation of thyroxine, which affects growth and development, maintains the structure of the central nervous system, maintains normal mental state and metabolism, and other important functions. Potassium deficiency can cause decreased and enlarged thyroid function, and the basal metabolic rate and vitality decrease. Endemic goiter disease, excessive iodine can also cause goiter, symptoms of poisoning.

In daily life, you should develop good eating habits, eat lighter meals, eat less or eat less salted foods, change cooking methods, reduce the intake of salt-flavored foods, and control the amount of salt you eat to be less than 6 grams per day. . If conditions are available, low-sodium, high-potassium, selenium-enriched, and iodine-enriched salts may be used. Persistence in the long term can be beneficial to health.
