Salt is an indispensable part of the human body. We cannot lack salt in our life. The Chinese Nutrition Society recommends that the daily salt intake of adults should be less than 10 grams. Medical experts confirmed that too much salt is harmful to human body. So what harm will it bring if you eat too much salt?
Too much salt is easy to get gastritis and stomach cancer
After ingesting excessive high-salt food, the high osmotic pressure of salt will cause direct damage to the gastric mucosa. High salt food will reduce the secretion of gastric acid and inhibit the synthesis of prostaglandin E2, which has the effect of improving the resistance of gastric mucosa, thus making the gastric mucosa vulnerable to damage and causing gastritis or gastric ulcer. At the same time, high-salt and salted foods contain a large amount of nitrate, which is converted into nitrite by bacteria in the stomach, and then combined with the amine in the food to form ammonium nitrite, which has a strong carcinogenicity.
Too much salt leads to high blood pressure
Medical experts have found that salt is easy to accumulate in the blood vessel wall. The greater the resistance of blood vessels, the higher the blood pressure, the heavier the load of viscera such as heart and kidney, the disruption of normal metabolic function of the body, edema will occur, and the risk of cerebrovascular accident or heart failure will increase significantly.
When you eat too salty, because you ingest a large amount of salt in your body, it first enters the blood circulation through the intestinal mucosa. The salt in the blood is high, and you must absorb water to dilute it, so people will feel dry mouth, and then drink a lot of water. This water enters the blood, which makes the volume of blood expand, and the blood pressure will rise. This is not to say that people with high blood pressure cannot drink water, but because if there is no excessive salt in the blood, the water cannot be retained in it, and it will soon be excreted through the kidney as urine, while the situation is different when the salt in the blood is too high. Salt will retain the water in the blood, which will increase blood pressure.
Excessive salt leads to osteoporosis
If there is too much sodium in the diet, there will be too much sodium ions competing with calcium ions in the reabsorption of renal tubules, which will increase the excretion of calcium. At the same time, sodium salt will also stimulate the parathyroid gland, increase the secretion of parathyroid hormone, activate the adenylate cyclase on the osteoclast membrane, destroy the dynamic balance of bone metabolism, and easily lead to osteoporosis and even fracture..
