Salt is an essential condiment in people's daily life. Salt can stimulate their appetite. Without it, they will eat tasteless and feel weak. However, if they eat too much for a long time, it will easily affect their health and induce many diseases. 16 1 Ping Liu, a 45-year-old patient in the hospital, said that his family has a heavy diet, especially after heavy physical labor in recent years, when cooking, they eat more salt, and the average family of five eats nearly 500 grams of salt a week. Later, I went to the hospital for low back pain and was diagnosed with chronic renal failure. Children often catch a cold, father's diabetes is aggravated, wife's bronchitis is frequent, and mother's hypertension is also aggravated. This family is the result of long-term emphasis on salt and salt.

1, eating too salty is easy to catch a cold.

Modern medical research has found that when the concentration of sodium chloride in human body is too high, sodium ions will inhibit the activity of respiratory cells and reduce the cellular immunity. At the same time, due to the decrease of saliva secretion in the oral cavity, the saliva secretion of bacteria in the oral cavity is reduced, which makes the cold virus in the oropharynx easily invade the respiratory tract. At the same time, due to the increase of sodium chloride concentration in blood, interferon in human body can also be reduced, resulting in decreased resistance. The above reasons make people who eat too much salt easy to catch a cold.

Eating too salty can easily lead to high blood pressure.

Clinical research shows that hypertension patients can reduce their blood pressure by10mmhg as long as they limit salt for one week.

3. Too salty diet can easily induce bronchial asthma.

Some foreign scholars have found in experiments that patients with bronchial asthma have increased their responsiveness to histamine after increasing their sodium intake, which makes them prone to illness and aggravate their condition. Therefore, limiting sodium salt can prevent the occurrence and aggravation of bronchial asthma to some extent.

Eating too salty will hurt the stomach and cause gastritis and gastric cancer.

After eating too much high-salt food, due to the high osmotic pressure of salt, it will directly damage the gastric mucosa. Animal experiments show that when rats are fed with high concentration of normal saline (12% or 20%), the gastric mucosa of rats will produce extensive diffuse congestion, edema, erosion, bleeding and necrosis, while low concentration of normal saline will not cause these pathological changes. High-salt food can also reduce gastric acid, easily damage gastric mucosa, and lead to gastritis or gastric ulcer. At the same time, high-salt and pickled foods contain a lot of nitric acid, which is transformed into nitrate by bacteria in the stomach and then combined with amines in food to form ammonium nitrite, which has strong carcinogenicity.

5. Kidney disease caused by salty diet.

Long-term high-salt diet will lead to kidney diseases, cardiovascular and cerebrovascular diseases, diabetes, hypertension and so on. About 80% patients with kidney disease also have high blood pressure. However, 80% of patients with this kind of nephropathy complicated with hypertension are volume-dependent hypertension, that is, the concentration of sodium ion in the body is too high. This is because sodium ions can retain water, which is called "sodium water retention" in medicine. Therefore, the clinical treatment of renal diseases requires that all patients with renal diseases should have a low-salt diet.

6. Eating too salty will aggravate diabetes.

Experts found in the experiment that the sodium content in food is directly related to the digestion and absorption speed of starch and blood sugar reaction. Salt can accelerate the digestion of starch by stimulating the activity of amylase, or accelerate the absorption of glucose by small intestine, so that the plasma glucose concentration of people who eat high-salt food is higher than that of people who eat low-salt food. Therefore, scholars remind diabetic patients to limit their salt intake as an auxiliary measure to prevent and treat diabetes.

So I suggest you eat lightly, and the taste will gradually change. Although beef is good, it is not suitable for these nine kinds of people.
