Eating too much salt can easily lead to water and sodium storage, which will increase the burden on the heart and worsen the symptoms of insufficient blood supply.

The safe daily intake of salt for healthy adults is 5 to 6 grams and no more than 8 grams. Excessive intake of salt for a long time can easily induce many diseases.

1. Raise blood pressure:

Many studies have confirmed that high-salt diet can increase blood pressure.

2. Promote atherosclerosis:

Eating too much salt can not only increase blood pressure, but also increase plasma cholesterol, which can promote atherosclerosis.

3. Causing gastritis and gastric cancer:

After ingesting excessive amounts of high-salt food, the high osmotic pressure of salt will cause direct damage to the gastric mucosa. High-salt foods will reduce gastric acid secretion and inhibit the synthesis of prostaglandin E2, which has the effect of improving the resistance of the gastric mucosa, making the gastric mucosa susceptible to damage and causing gastritis or gastric ulcers. 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 combines with amines in the food to form ammonium nitrite, which is highly carcinogenic.

4. Susceptible to colds:

People who eat more salt are more likely to catch colds. Because high-concentration salt can inhibit the activity of respiratory cells and inhibit their disease resistance; it can also reduce saliva, reduce lysozyme in the mouth, and increase the chance of viruses and bacteria in the upper respiratory tract.

5. Accelerate bone calcium loss:

If there is too much sodium in the diet, there will be too much sodium ions competing with calcium ions during renal tubular reabsorption, causing calcium to excretion increases. At the same time, sodium salt will also stimulate the human parathyroid gland, increase the secretion of parathyroid hormone, thereby activating adenylate cyclase on the osteoclast membrane, destroying the dynamic balance of bone metabolism, and easily causing osteoporosis or even fracture.

6. Salt can "hydrate" the human body:

That is to say, salt has a certain adsorption force on water. If there is too much salt in the human body, the water requirement will also increase accordingly, thus This causes excess water to be retained in the body, thus causing high blood pressure. Someone has investigated the eating habits of residents in northern Tokyo, Japan. They eat an average of 25 grams of salt a day, and people with high blood pressure account for 30 to 40% of all residents. In other areas of the world, they only eat 5 to 15 grams of salt a day. Only 8 to 10% suffer from high blood pressure; Eskimos living in the Arctic Circle eat less than 5 grams of salt per day, and almost none suffer from high blood pressure. Therefore, experts recommend that adults should not eat more than 12 grams of salt per day.

7. Excessive salt intake is the first cause of kidney disease

The kidney is a very hard-working organ. It mediates the nutritional balance of the human body. It excretes excess salt from the body and is highly A salt diet directly increases the workload of the kidneys. If a person eats a high-salt diet for a long time, it will eventually cause nephritis, kidney deficiency, kidney failure, edema, atrophy, and the inability to excrete excess salt from the body. In this way, people will get sick, which initially manifests as pain in the waist and back, stiffness, etc.

Salt itself is cold in nature. Excessive consumption will narrow blood vessels and block blood flow. When exposed to external cold stimulation or dehydration, the kidneys will not be able to work normally.

8. Exacerbating the condition of diabetes

Recently, foreign experts have discovered in experiments that the sodium content in food is directly related to starch digestion and absorption speed and blood sugar response. Salt can accelerate the digestion of starch by stimulating the activity of amylase and accelerate the absorption of glucose released by digestion in the small intestine. Therefore, experts remind diabetic patients to limit salt intake as a measure to prevent and treat diabetes.
