Is it better for people to eat salty food or light food? It's better to tell the reason.

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

Su Shi, a great writer in the Song Dynasty, wrote in his poem, "Is it that Wen Shao forgets the taste, and you will eat salt in March?" If you don't put some salt in your dishes when you eat, even 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. It regulates the balanced distribution of water in human body, maintains the osmotic pressure inside and outside cells, participates in the formation of gastric acid, promotes the secretion of digestive juice and can 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 can't do without salt. Eating too little salt will also lead to low sodium content in the body, loss of appetite, weakness of limbs and dizziness. In severe cases, there will be symptoms such as anorexia, nausea, vomiting, accelerated heart rate, weak pulse, muscle spasm, blurred vision and weakened reflex. In ancient times, the Netherlands, Sweden and other countries stipulated that people who violated the criminal law were not allowed to eat salt for a period of time as punishment.

2. Disadvantages

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

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

Animal experiments show that after feeding rabbits with high-salt feed for 12 months, their bone density is reduced by 5%.

The China Nutrition Society suggests that the daily salt intake of adults should be less than 1 grams, and the World Health Organization suggests it is even lower, 3 to 5 grams per person per day.

Specifically, the following salt restriction methods can be adopted: 1. Drink milk or soybean milk for breakfast, and eat some pasta such as bread or steamed bread without salt at all. 2. Eating some sweet potatoes for lunch or dinner can not only reduce the salt intake, but also increase the potassium intake. 3, food processing and cooking, try to add less salt, in order to improve the taste, you can add less sugar, vinegar or spicy. 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 higher; Taro, bamboo shoots, potatoes, water chestnuts, rape, celery, Chinese cabbage, tomatoes, etc. can be selected in vegetables, and jujube, hawthorn, bananas and apples can be selected in fruits. In addition, lean meat, fish and milk also contain more potassium.

Eating too much salt makes you sick

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

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

Left ventricular hypertrophy is a risk factor for premature cardiovascular disease. In the past, people recognized that hypertension was the main cause. In recent years, experts have found that salt intake is an important independent factor of left ventricular hypertrophy, regardless of blood pressure, even more important than hypertension itself, thus indicating that salt control is a measure to prevent and treat cardiovascular disease.

High dietary salt intake in kidney disease will promote pathological changes in renal blood vessels, increase the burden on the kidney and affect renal function. Experts found that high salt intake can accelerate the decline of renal function in patients with kidney disease. Therefore, experts warn 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 intake and high salt intake is an important reason for the decrease of calcium in bones and osteoporosis.

Asthma experts found that after moderate reduction of salt intake in men, asthma symptoms were alleviated, the dosage of tracheal dilators was reduced, and the maximum expiratory volume was increased, but this phenomenon was not found in women. Therefore, experts also strongly advocate that asthma patients should also 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 1 grams to 5 grams, and use vinegar as a seasoning in their daily lives, so as to be beneficial to health.
