The less salt you eat, the healthier you are. Eating less salt is actually eating less sodium. Although eating too much salt will increase the burden on the body and is not good for blood pressure, sodium is also an essential nutrient and participates in many physiological functions of the human body. Therefore, we must take a certain amount of salt every day to maintain the balance of sodium in the body.
China has one of the highest salt intake countries in the world. There is no doubt that a long-term high-salt diet is harmful to health, and it is necessary for ordinary people to control the amount of salt in their daily lives. But salt is not a scourge, and sodium is one of the essential nutrients for human body. Pay attention to a balanced diet, no matter what you eat, it is not good, eat big depressions and eat too little, including salt.
Matters needing attention in edible salt
1, buy less and eat in time
Buy a small amount, and then buy it after eating, in case of iodine volatilization. Because potassium iodate will decompose and volatilize under the conditions of heat, light, wind and humidity.
2. Avoid high temperature
Avoid putting iodized salt at high temperature when cooking soup. The edible rate of iodized salt in cooking and frying is only 10%, and the intermediate edible rate is 60%. The edible rate of iodized salt during cooking is 90%; The edible rate of cold iodized salt can reach 100%.
3. Avoid prolonged exposure to containers.
Iodized salt is easy to volatilize if it is exposed to sunlight and air for a long time. It is best to put it in a colored glass bottle and seal it tightly with the back cover.
4, avoid adding vinegar
The combination of iodine with acidic substance will be destroyed. According to the test, if vinegar is added during cooking, the consumption rate of iodine will decrease by 40% ~ 60%. In addition, when iodized salt meets acidic vegetables (such as sauerkraut), the consumption rate will also drop.
