What are the hazards of salt to the human body

Do you still remember the stories our elders told us when we were young? When there is no food to eat, they rely on salt to sustain their lives. This is enough to illustrate the importance of salt. Well in our real life, as people's material living standards continue to improve, there are more and more types of salt, and salt is indispensable in people's daily food. So many people have questions, what are the harms of salt to the human body? Let’s find out together.

1. Eating too much salt can cause freckles. Eating too much salt may cause freckles on the cheeks; if the diet only consumes animal fat and protein, it will affect the normal function of the liver and make the freckles more noticeable. Therefore, people with freckles must eat plenty of fruits and vegetables. In addition, drugs are the enemy of the skin, especially sleeping pills, which can cause excessive acidity in the body, hormone imbalance, and freckles on the face.

2. Osteoporosis. If there is too much sodium salt in the diet, there will be too many sodium ions competing with calcium ions during renal tubular reabsorption, increasing calcium excretion. At the same time, sodium salt will stimulate the human parathyroid glands, increase the secretion of parathyroid hormone, thereby activating adenylate cyclase on the osteoclast membrane, destroying the dynamic balance of bone metabolism, and making osteoporosis and even fractures more likely to occur.

3. Cold. Modern medical research has found that when the sodium chloride concentration in the human body is too high, sodium ions can inhibit the activity of respiratory cells and reduce cellular immunity. At the same time, due to the reduced saliva secretion in the mouth, the lysozyme in the mouth is reduced, making it easier for the cold virus to invade the respiratory tract. In addition, due to the increased concentration of sodium chloride in the blood, the interferon in the body can be reduced, thereby reducing resistance. All of the above reasons will increase the chance of catching a cold.

4. Gastritis and gastric cancer. After consuming excessive high-salt food, the high osmotic pressure of salt will cause direct damage to the gastric mucosa. High-salt food will reduce gastric acid secretion and inhibit the synthesis of prostaglandin E2. Prostaglandin E2 has the effect of increasing the resistance of gastric mucosa, thus making the gastric mucosa susceptible to damage and causing gastritis or gastric ulcer. At the same time, high-salt and salted foods contain large amounts of nitrates, which are converted into nitrites by bacteria in the stomach, and then combined with amines in food to form ammonium nitrite, which is highly carcinogenic.

Through the above understanding and our common sense, we can see that a moderate amount of salt is good for the human body, but when we consume too much salt, there will be adverse effects of one kind or another. The harm of salt to the human body mainly includes easy growth of freckles, osteoporosis, colds, and easy to get gastritis, etc. This reminds us that we should add a proper amount of salt to the dishes in our daily life, and remember not to overdo it to avoid causing harm to the body.
