Salt grid requirements, health benefits
Although the United States to former President Ronald Reagan has passed away, but his emphasis on self-care of people living style has always been difficult to forget. So far, all previous U.S. president Ronald Reagan in the most longevity in the one. So, why he can live longer? » U.S. President Ronald Reagan in office, it is a good thing the reporter asked the secret of his longevity, unthinkingly Reagan said: "eat salt."谁知this "talk" has led to strong opposition from local Salt Merchants, Reagan;s "Salt storm" 1:00 fired in the hubbub.
Salt, also known as the "Xianyan", chemical composition is sodium chloride, potassium salt as the high sodium low. As early as over 5,000 years ago, mankind has been using sea salt. Chinese have always salt can see very precious. Li Shizhen in the "Compendium of Materia Medica", he said: "flavor, Weici indispensable." Why is salt so important? «This is because the human body are not enough salt will be sick. Heart Without it, can not be normal beat; acid salt is the major raw materials, such as in the lack of chlorine, will make acid indigestion caused by the lack of, loss of appetite. Chiyan long-term, people will be every weakness, dizziness, muscle twitching body, medicine called "loss of salt." Osmotic pressure to maintain body fluids with salt and acid-base balance and maintain the nerve and muscle stress, regulation of physiological functions, and other important role. In addition, there are antibacterial salt, sterilization, preservation of the role. Today, the salt face more and more, the market has emerged in many trace elements including the strengthening of health salt, let people have more choice.
1. Low-sodium salt containing sodium chloride, potassium chloride and magnesium sulfate. Low-sodium calcium does not function, but to replace the ordinary low-sodium salt, low-salt diet can be achieved. Scientific experiments show that low-sodium salt can improve the body sodium, potassium, magnesium imbalance of essential hypertension patients have significant blood pressure effects. Low-sodium salt with all ages, the long-term consumption can lower blood pressure in the crowd, to achieve the role of prevention of hypertension.
2. Strengthening calcium in the salt contains a lot of calcium. Calcium do not dissolve in water, but the body after intake, could be released from gastric acid and dissolved calcium for absorption into the body. Calcium needs of the people, strengthen the daily consumption of calcium in the diet was able to achieve the purpose of calcium.
3. Zinc Zinc Salt strengthening of protein as an important component of the human body is essential trace elements. Xinyuan Su will lead to a lack of growth retardation of children, malnutrition, anemia, but will also affect the body;s immune function and intellectual level. Children and the elderly most vulnerable to zinc deficiency, such groups to strengthen long-term consumption of zinc salts, can effectively complement Xinyuan Su, enhance human health.
4. Se Se strengthen the salt is essential trace elements. Large epidemiological survey data indicate that the lack of selenium and cancer, cardiovascular diseases such as a very close relationship. Se strengthen the long-term consumption of salt, will enable people in the intake of salt, selenium be added elements of effective.
Although salt on the human body has an important role, but experts still advise people that salt intake must be strictly controlled. Health experts recommend adults daily intake of salt for the safety of five to six grams, up to more than eight grams, if the long-term excessive intake of salt, it is easy to diseases induced by the following:
1. Bone injury too much salt in the diet, in the tubular reabsorption, there will be excessive sodium and calcium competition, increased excretion of calcium. At the same time, the sodium salt will stimulate the parathyroid hormone, parathyroid hormone secretion increase, thereby activating osteoclasts, the cells adenylyl cyclase, the destruction of bone metabolism in dynamic equilibrium, even prone to osteoporosis Fractures.
2. Cold modern medical study found that people in high concentration of sodium chloride, sodium ions can inhibit the activity of respiratory cells, immune cells decreased. At the same time due to reduced secretion of saliva in the mouth, so that the mouth lysozyme reduced, so the mouth, pharynx the flu virus more easily penetrated respiratory tract. In addition, because of increased blood concentration of sodium chloride, which can reduce the resistance of interferon in lower. The above reasons will lead to the human body increases the odds of suffering from the flu.
3. Gastritis, gastric cancer excessive intake of high-salt food, the osmotic pressure due to high salt, the gastric mucosa will cause direct damage. High-salt food will reduce gastric acid secretion, and inhibit the synthesis of prostaglandin E2, and prostaglandin E2 has increased the role of gastric resistance, so easy to make gastric damage arising from gastritis or gastric ulcer. At the same time high-salt and salted foods contain large quantities of nitrite, it was bacteria in the stomach into nitrite, and then with amines in the food-combining ammonium nitrate, is highly carcinogenic.
