Tell me about it.

First of all, talk about the benefits of eating salty:

Su Shi, a great writer in the Song Dynasty, wrote in his poem: "Don't you forget the taste? You can eat without salt in March?" If you don't put some salt in the dish when you eat, even the delicacies are like chewing wax. Salt is not only an important condiment, but also an indispensable substance to maintain the normal development of human body. Adjust the balanced distribution of water in human body, maintain osmotic pressure inside and outside cells, participate in the formation of gastric acid, promote the secretion of digestive juice, and stimulate appetite; At the same time, it also ensures the pH necessary for the action of pepsin, maintains the balance of pH in the body and the normal circulation of body fluids. People cannot live without salt. Eating too little salt can also lead to low sodium content in the body, loss of appetite, weakness of limbs and dizziness. In severe cases, there will be anorexia, nausea, vomiting, increased heart rate, weak pulse, muscle spasm, blurred vision, weakened reflex and other symptoms. In ancient times, the Netherlands, Sweden and other countries stipulated that people who violated the criminal law were not allowed to eat salt as punishment for a period of time.

Two: unfavorable reasons

Everything has two sides, and eating salty food is also harmful;

1, hypertension: Many studies have confirmed that high-salt diet has the effect of hypertension. 2, promote atherosclerosis: eating more salt can not only raise blood pressure, but also raise plasma cholesterol, which has the effect of promoting atherosclerosis. 3. Gastric cancer: High concentration of salt can destroy gastric mucosa and induce gastric cancer. 4, easy to catch a cold: people who eat more salt are easy to catch a cold. Because high concentration of salt will inhibit the activity of respiratory cells and their disease resistance; At the same time, it can also reduce saliva and lysozyme in the mouth, and increase the chance of upper respiratory tract virus and bacterial infection. 5, accelerate the loss of bone calcium: eating too much salt is easy to osteoporosis.

Animal experiments showed that the bone mineral density of rabbits fed with high-salt feed 12 months decreased by 50%.

The Nutrition Society of China suggested that the daily salt intake of adults should be less than 10g, and the World Health Organization suggested that it should be even lower, 3 ~ 5g per person per day.

Specifically, the following salt restriction methods can be adopted: 1, drink milk or soybean milk for breakfast, eat some pasta such as bread or steamed bread, and do not add salt at all. 2. Eating some sweet potatoes for lunch or dinner can not only reduce salt intake, but also increase potassium intake. 3. When food is processed and cooked, try to add less salt. In order to improve the taste, you can add less sugar, vinegar or spicy food. 4. Do not eat or eat less pickles and foods with high salt content, such as cured meat products. 5. Eat more foods containing more potassium, such as beans, vegetables and fruits. Beans and dried beans contain the most potassium; The potassium content of buckwheat and millet in cereals is high; Taro, bamboo shoots, potatoes, water chestnuts, rape, celery, Chinese cabbage, tomatoes, etc. You can choose from vegetables, and jujube, hawthorn, banana and apple can be selected from fruits. In addition, lean meat, fish and milk also contain more potassium.

I ate too much salt and got sick.

It has long been recognized that high salt intake caused by high salt diet is an important factor to induce hypertension. Recently, medical research has found that excessive salt intake can also cause many adverse reactions.

Stroke experts suggest that excessive salt intake will increase the incidence of stroke. Although the mechanism of this relationship between salt and stroke is unclear, reducing salt intake can not only lower blood pressure, but also reduce the degree of arteriosclerosis, thus effectively reducing the incidence of stroke.

Left ventricular hypertrophy is a risk factor for early cardiovascular disease. In the past, people realized that high blood pressure was the main cause. In recent years, experts have found that salt intake is an important independent factor of left ventricular hypertrophy, which has nothing to do with blood pressure and is even more important than hypertension itself, thus indicating that salt control is a measure to prevent and treat cardiovascular diseases.

Excessive intake of salt in the diet of nephropathy will promote the pathological changes of renal blood vessels, increase the burden on the kidney and affect the renal function. Experts have found that high salt intake will accelerate the decline of renal function in patients with kidney disease. Therefore, experts remind people that patients with kidney disease must control the intake of sodium salt.

The dietary salt content of osteoporosis is the main determinant of calcium excretion. The higher the salt intake, the higher the urinary calcium. Studies have shown that high urinary calcium caused by low calcium and high salt intake is an important cause of calcium deficiency and osteoporosis in bones.

Asthma experts found that after men moderately reduced salt intake, asthma symptoms were alleviated, the amount of tracheal dilator was reduced, and the maximum expiratory volume was increased, but women did not find this phenomenon. Therefore, experts also strongly advocate that patients with asthma should strictly control the intake of sodium salt.

In view of the many adverse reactions of the above-mentioned high-salt diet, experts suggest that people should change their daily salt intake from 10g to 5g, and use vinegar as seasoning in their daily life, which is beneficial to their health.
