Excessive salt restriction It is often believed that “kidney patients must give up salt”, which is misleading. We know that salt is an essential component of the body, and long-term salt deprivation can lead to electrolyte disorders, such as hyponatremia, which is detrimental to the body. From the medical point of view, serious “salt deficiency” will also appear neurological damage, and even cause death, especially in elderly patients, so you can not blindly quit salt. The issue of salt consumption in kidney disease patients should be analyzed specifically, no matter what kind of nephritis, absolute salt withdrawal is wrong. When patients have obvious edema or increased blood pressure, they should consider reducing salt intake to avoid aggravating water and sodium retention. When the patient does not have clinically significant edema or hypertension, there is no need to restrict salt intake more. Indications for salt restriction: If you have kidney disease with low urine, hypertension, or significant edema, you should restrict salt intake, but it is not necessary to abstain from all of them. Also do not advocate eating too salty food, such as salted fish, cured meat, pickles, etc.. Too much salt is not good for health, even for normal people, not to mention the sick. The World Health Organization advocates a low-salt diet, less than 6 grams per day for adults, preferably no salt for children within half a year, no more than 1 gram per day for 6 months to 1 year, no more than 2 grams per day for 1-3 years, and no more than 3 grams for 4-6 years. You should also be aware of “hidden salt” in your daily life. Such as hiding in snacks, fast food, packaged food, seasonings often also contain salt. For example, soy sauce, every 5 ml of soy sauce is equivalent to 1 gram of salt, in addition, like vinegar, monosodium glutamate, sauces, seasoning packages also contain sodium, even many vegetables, such as hollow vegetables, bean sprouts, purple cabbage, also contains a certain amount of salt. Even in the fritters, doughnuts, bread and cookies that we use as staple food, many of them also contain salt, we just don’t realize it.
