The intake of salt should not exceed 6 grams per person per day. Although seemingly inconspicuous, it can turn food into infinite flavor, which is an essential part of the seven things to open the door. However, you should know that the more salt, the better! According to a study by the French National Institute of Health Medicine, at least 75,000 people in France suffer from cardiovascular diseases every year due to excessive salt consumption, of which 25,000 people die of serious illness, which is four times the death toll from traffic accidents in France. Sodium is the culprit. The main component of salt is sodium chloride, and chlorine, sodium and potassium are the main components of human electrolyte. And sodium and potassium, just like two equal and balanced comrades. Sodium is outside the cell and potassium is inside the cell. Both of them maintain the balance of osmotic pressure, moisture and pH value inside and outside the body cells. Once the balance is broken and the sodium content increases, it will do harm to the human body! Salt-loving makes people osteoporosis: Eating more salt will not only make people salty, but if you indulge in strong food, the "devil" in salt will exhaust the calcium in people's bones, and finally people will lose their health and even their lives because of osteoporosis. The devil in salt is sodium, which accounts for about 40% of the main components of salt and is the killer of bone loss in human body. Nutritionists say that sodium usually causes women to lose about 1% of their bones every year, and women with hypertension lose their bones much faster than women with normal blood pressure. In addition, according to the statistics of the American Osteoporosis Foundation, about 8 million women in the United States suffer from osteoporosis, and the number of people who die from diseases such as osteoporosis is as high as 72,000 every year. Strictly speaking, sodium itself is not useless. The human body needs this mineral for nerve information transmission and muscle contraction. If it is not properly supplemented, there will be some functional problems. But the bad thing is that too much sodium is harmful; Generally speaking, human kidneys excrete used sodium with urine every day, but every time 1000 mg of sodium is excreted, about 26 mg of calcium will be consumed at the same time. It seems to have no effect, but the more sodium the human body needs to excrete, the greater the consumption of calcium, which will eventually affect the calcium necessary for bone health. Salty cold: Many experts at home and abroad believe that bad eating habits are closely related to colds. Eating too much high-salt food will lead to decreased saliva secretion, edema, congestion and virus increase of oral mucosa, which will easily cause upper respiratory tract infection and eventually lead to a cold. Eating too much high-sugar food will consume water, vitamins and other nutrients in the body, cause dry mouth, make immunity low, and then induce a cold. Eating too much high-fat diet, such as cream, meat, broth, etc. It will reduce the antiviral ability of immune cells in the body and easily cause a cold. In order to prevent colds, we should stay away from the "three highs" diet with high salt, high sugar and high fat. Strong taste, easy to get stomach trouble: gastric mucosa will secrete a layer of mucus to protect itself, but mucus is afraid of salt. If you eat too salty, the protective layer of gastric mucosa will disappear over time. How can a delicate stomach stand ups and downs? It will cause gastric ulcer, gastritis and even gastric cancer for a long time. There are more wrinkles when there is more salt: there is a French saying that "a beautiful woman is born on the mountain, not by the sea." According to French beauticians, because women who live by the sea usually consume more salt, their skin is prone to wrinkles, which naturally affects their appearance. Women in mountainous areas eat less salt, and their skin is often smooth and delicate. Why is it easy to get wrinkles when you eat too much salt? Experts on the website of the French National Medical College explained that salt exists in human blood and body fluids in the form of sodium ions and chloride ions, which plays a very important role in maintaining osmotic pressure, acid-base balance and water balance. If you eat too much salt, sodium ions in your body will increase, leading to dehydration of facial cells, which will cause skin aging, which will increase wrinkles over time. Medical experts remind everyone that eating too much salt will not only cause high blood pressure, but also directly affect people's appearance. If you want good skin, the more scientific way is to drink plenty of water to help your skin detoxify.
