It is the better whether the diet of less salt is the lower?
Reader Mr. Zhao electricity consult recently most, he the intersection of hypertension and patient in itself, should propagate a hypertension patient diet of less salt during these years, not merely until salt that spend originally all replace into low sodium salt in the house Mr. Zhao for this reason, and the consumption of cooking and all paying attention to the salt very much each time, insist that will come down in one year, Mr. Zhao finds what improvement hypertension and symptom have not got. Mr. Zhao is a person fond of salty food on ordinary days, the diet of less salt always lets him think have no appetite for food, it is not fragrant to have a meal, does he want to find out whether the diet of less salt is really so necessary? The principal ingredients of the salt are sodium chloride, 39% among them are sodium, 61% are chloride. The salt can resolve into sodium ion and chlorine ion in the human body, is playing a different role respectively. Sodium ion can keep blood capacity and cell of human whole body permeating and pressing, maintain normal excitement and irritability of nerve and muscle, activate human muscles to shrink etc.. Chlorine ion can help to regulate the acid-base balance of the human body, produce the gastric acid and activate the amylase. These are extremely important to life activity. A lot of people know in life the diet of high salt is disadvantageous to health, think one-sidedly it is the better that it is the less to eat salt, not even eating the salt, in fact this is a mistaken idea. As everyone knows, the high salt can make blood pressure rise, the less salt can make blood pressure reduce, the northerner eats and has more salt more than the southerner, so the northerner's blood pressure is generally higher than that of the southerner. The doctor often tries to persuade the patient who suffers from hypertension too " Don't eat too saltily " ,The diet should be a bit lighter, beneficial to controlling blood pressure. In fact, not all eats salt hypertension will take place to a lot of people. Studies have suggested, about 1/5 of the people are sensitive to the salt. Hypertension will take place when the people have too much salt, such as already having hypertension that will make blood pressure higher. Carry on the 4 -year long observation to 1900 hypertension patients abroad, analyze the salt content in their urine regularly, find the myocardium infarction morbidity of the person more normal than the content of the patient of the salt with lowest content is 4 times higher in the urine. So, even a hypertension patient, it is not the salt that is eaten the less well. Medical science still can't tell crowds sensitive to salt at present, so World Health Organization proposes, the salt amount of every solar eclipse should be limited to 5 grams. Less salt diet to say, take salt to be little and kind, take salt. If the excessive limit salt will have certain side effects. Sodium salt is taken in insufficiently, will permeate and press to overbalance inside and outside collective cells, impel the moisture to enter in cells, produce the brain edema of different degrees, the lighter presents the consciousness obstacle, including having a liking for and sleeping, weak, mind is in a trance, the serious one can go into a coma. If excessively limit the absorption of the salt for a long time, will lead to the fact serum sodium content is too low, thus cause the nerve, spiritual symptom and present losing the appetite, myasthenia of limbs, dizzy, etc, will also present apocleisis, nausea, vomit when being serious, accelerating, pulse of heart rate is thin and delicate, muscle convulsion, eyesight are fuzzy, reflect symptom of weakening etc., called on medical science " Low sodium syndrome " . Extreme the intersection of limit and salt can make humoral capacity drop, renin - the intersection of angiotensin and systematic sympathetic the intersection of nervous system and active increase, can cause some patients' blood pressure to rise instead.
