Salt, also known as Table Salt, is one of the most important substances for human survival and is the most commonly used seasoning in cooking. Potassium chloride is added to the salt produced in some regions to reduce the Sodium Chloride content and reduce the incidence of hypertension. At present, there is a common problem of excessive salt intake in the country, with an average of more than 10 grams per day, and some provinces have reached 15 grams. China's food culture is said to be "Southern sweet salty salty," and this eating habit is an important cause of the higher incidence of hypertension in the northern region than in the southern region. Since it is difficult for many people to change their dietary habits, it is difficult to achieve an effect only by limiting the amount of salt, and controlling sodium in salt is a good idea. Low sodium salt is 40% potassium chloride instead of sodium chloride, reducing the sodium content, suitable for people with diabetes, nephritis, gastritis, hypertension and familial hypertension. However, the effect of low-sodium salt in large-scale use in the population and other health problems that may be caused has not yet been scientifically verified. There is no definite evidence for its application. In order to avoid the risk of excessive potassium intake, patients with renal failure, fever and other diseases in the acute phase, acidosis, taking certain anti-cancer drugs, massive bleeding, before and after surgery and severe trauma, should be cautious with low sodium salt, or Eat under the guidance of a doctor. Long-term low blood pressure, diarrhea patients, sweating during high-intensity exercise, hot summer conditions, the body should increase sodium intake, it should not use low sodium. Iodine salt tips Iodine salt iodine easily evaporates when exposed to high temperatures, humid environments, or acidic substances such as vinegar. Therefore, families should pay attention to the purchase, preservation, and use of iodized salt: Purchase small plastic bag packaging, designated trademark, iodized salt with iodized salt, and do not buy salt or salt without salt.
