Is it OK to eat too much salt? Is it okay to eat too much salt

Eating too much salt can lead to kidney disease.

Of course it's not good, it's not good to eat too much.

I copied the World Health Organization's recommendation: the general population should consume 6-8 grams of salt per day. The dietary guidelines for Chinese residents advocate that the daily amount of salt per person should be less than 6 grams.

For people with mild hypertension, the U.S. Committee on Nutrition and Human Needs recommends that it should be controlled at 4 grams, which is also appropriate for patients with cardiovascular and cerebrovascular diseases in China. So how is the daily salt intake calculated? Here's how a rough estimate is calculated.

After you buy 500 grams of salt, 1 has the date of buying salt, when the 500 grams of salt is eaten, and then write down the date, then you know how many days the 500 grams of salt have been eaten, divide the amount of salt eaten by the number of days you eat salt, and then divide by the number of people in the family to get a rough salt intake per capita. Another issue to note is that soy sauce is also another major part of our diets. Therefore, when calculating the amount of salt, the amount of salt ingested through soy sauce should also be added, and the calculation method is the same as above.

However, it should be noted that the salt content of soy sauce is about 18%, and you only need to multiply the amount of soy sauce by 18% to get the amount of salt per capita consumed by eating soy sauce. Add this amount to the amount of salt and you'll get the average amount of salt per person in your household per day.

Excessive salt intake can affect physical health, and the most direct result is high blood pressure. Since the osmotic pressure of human body fluids is constant, for every 1 gram of salt ingested, an extra 111 grams of water is needed to match it to form the osmotic pressure of "normal saline", which is stored in the tissues. This leads to an increase in the amount of water in the blood vessels, which increases the pressure on the blood vessel walls, inducing high blood pressure.

The dietary style of Chinese residents is very different from that of the West, mainly manifested as high salt and low potassium, especially in the diet of northerners and the elderly, the high salt load, and the incidence of hypertension is also increased, and most of them are volumetric hypertension and high blood pressure with low renin levels.

The American Heart Association (AHA) pointed out at the 2013 "Epidemic and Prevention and Nutrition, Physical Activity and Metabolism Science Congress" that in 2010, there were 23 million deaths from heart disease, stroke and other cardiovascular and cerebrovascular related diseases worldwide, which may be related to excessive sodium intake, accounting for 15% of deaths from such diseases. About 1 million people (40%) of cardiovascular deaths associated with excessive sodium intake died before the age of 69.

In addition to high blood pressure, eating too much salt can also lead to the following diseases: high blood pressure, low blood flow to the liver and kidneys, which increases the metabolic pressure on the liver and kidneys and impairs their normal function; Eating too much salt will also reduce saliva secretion, which will reduce lysozyme in the mouth, making it difficult to fight viral infections; The nitrite contained in pickles will be converted into nitrosamines under the action of gastric acid and bacteria, which is easy to cause stomach cancer; An increase in sodium ions in the body can lead to dehydration of facial cells and increase wrinkles; For every 1 gram of sodium excreted by the human body, about 26 mg of calcium will be depleted, so eating too much salt can easily lead to osteoporosis.

Eating too much salt can be harmful to the body. First, some studies have confirmed that the occurrence of hypertension is positively correlated with salt intake, and the more salt intake, the higher the incidence of hypertension;

Second, eating too much salt will cause nutrients to be lost, for example, excessive salt intake will cause the body's calcium loss is more obvious, and when stir-frying, too much salt will destroy the cell structure of vegetables, so that some beneficial nutrients in the cells, such as potassium and calcium, will be lost;

Third, eating too much salt will induce the occurrence of tumors, especially gastric cancer, many studies have shown that smoked meat and pickled products have a certain promotion and inducing effect on gastric cancer, and these pickled products are because of the many ingredients in salt.

Eat salt in moderation in your life to protect your health.

Too much salt can increase the burden on the kidneys and cause edema. Although everyone's taste is different, and each meal may be salty, the salt concentration in the human body is always stable within a certain range under the regulation of the kidneys. If the intake of salt exceeds the required amount for a long time, especially when the kidney function is reduced, the kidneys will not be able to excrete salt according to the body's needs, and the excess salt will accumulate in the tissues, and the tissues will absorb water to dilute in order to maintain osmotic balance, resulting in the retention of water and sodium salts, and the patient will have edema symptoms.

Therefore, people with kidney disease need to severely limit their salt intake.

Eating too much salt can cause high blood pressure. Comparing Japanese and Eskimos, the prevalence of hypertension is low among Eskimos who eat less salt, while the prevalence of hypertension is high among residents of northern Japan who consume up to 20 grams of salt per day. Studies have shown a linear relationship between sodium intake and the prevalence of hypertension, meaning that the more salt you eat, the higher your blood pressure is likely to be.

This is due to the retention of water and sodium salts in the body, which leads to swelling of vascular smooth muscles, thinning of the lumen, and increased vascular resistance, thereby increasing blood pressure; At the same time, the increase in blood volume and the increase in the amount and output of blood return to the heart increase the burden on the heart and kidneys, which can further cause an increase in blood pressure.

In addition to kidney disease and high blood pressure, arteriosclerosis, coronary heart disease, gastritis, and stomach cancer may all be associated with eating too much salt. Because sodium can promote blood circulation, increase cardiac output, and directly increase the burden on the heart, a high-salt diet is not good for coronary patients with insufficient cardiac blood flow**. Due to the high osmotic pressure of table salt, excessive high-salt food can also cause direct damage to the gastric mucosa, leading to gastritis, gastric ulcer, and even inducing cancer.

In life, there is a seasoning that each of us cannot live without, and that is salt. However, due to long-term heavy diets, most people actually have excessive salt intake. Long-term high-salt diet has many effects on the body and also increases the risk of many diseases.

1. Raise blood pressure: Many studies have confirmed that a high-salt diet has the effect of raising blood pressure. 2. Promote atherosclerosis

Eating more salt can not only increase blood pressure, but also increase plasma cholesterol and promote atherosclerosis. 3. Gastric cancer: high concentration of salt can damage the gastric mucosa and induce gastric cancer.

4. Prone to colds: People who eat more salt are prone to colds. Because high concentration of table salt can inhibit the activity of respiratory tract cells and inhibit their ability to resist disease; At the same time, it can also reduce saliva, reduce the lysozyme in the mouth, and increase the chance of viral and bacterial infection in the upper respiratory tract.

5. Accelerate bone calcium loss: eating more salt is easy to suffer from osteoporosis.

Not good. When you get older, you tend to get high blood pressure.

It's not good, if you eat too much and drink water, your family's water bill will cost more!

Bad hurts a lot to **.

It is not good to eat too much salt under any circumstances.
