How low the salt content is considered a severe salt deficiency

Plasma salt Na 115 mEq L is severe salt deficiency.

Management of mild, asymptomatic hyponatremia (i.e., plasma NA 120mEq L) is clear, especially if primary** can be detected and ruled out. Therefore, in patients with thiazide-induced hyponatremia, diuretics should be discontinued and sodium and/or potassium deficiencies should be supplemented. Similarly, if mild hyponatremia is due to inappropriate parenteral hydration in patients with renal drainage disorders, it is sufficient to stop hypotonic fluids**;

The presence of hyposodium, hyperkalemia, and hypotension should indicate adrenal insufficiency and may require glucocorticoids (hydrocortisone 100 200 mg instilled for 4 hours in 5% glucose and saline 1 L for the purpose of **acute adrenal insufficiency). When adrenal function is normal, but hyponatremia is associated with ECF volume loss and hypotension, administration of saline usually corrects hyponatremia and hypotension. If the underlying disease improves slowly or the serum sodium is significantly low (i.e., plasma NA 120mEq L), water restriction of 500 to 1000 mL for 24 hours is very effective.

Most patients with dilutive hyponatremia due to renal sodium retention (heart failure, cirrhosis, or nephrotic syndrome) ECF volume expansion with dilutive hyponatremia rarely have symptoms due to hyponatremia. In this case, water restriction is often successful in binding to the underlying disorder**, and prescribing plain (ACE inhibitors) in combination with loop diuretics can correct refractory hyponatremia in patients with heart failure. Administration of prescribe and other ACE inhibitors can be equally effective against other ECF volume increases characterized by increased renin-angiotensin-aldosterone activity, especially for nephrotic syndrome.

If SIADH is present, a strict restriction of 25% to 50% of water volume is required. Durable correction is dependent on the success of the underlying disease**.

If the human body lacks salt, the nervous system will be very weak and the whole body will be weak.

At the same time, the lack of salt will make the secretion of digestive juices uncoordinated, which in turn will reduce appetite; At the same time, it will also reduce the pH necessary for the action of pepsin, leading to an imbalance in the body's pH and abnormal circulation of body fluids.

Eating too little salt will also cause the sodium content in the body to be too low, and dizziness and other phenomena will occur; In severe cases, symptoms such as anorexia, nausea, vomiting, rapid heart rate, weak pulse, muscle spasms, blurred vision, and decreased reflexes may occur.

Not.

Although eating more salt will increase the burden on the body and is not good for blood pressure, sodium is also an essential nutrient element for the human body and participates in many physiological functions of the human body. Therefore, we must consume a certain amount of table salt every day to maintain the balance of sodium in the body.

Our country has one of the highest salt intakes in the world. There is no doubt that a long-term high-salt diet will harm the body, and it is necessary for ordinary people to control the amount of salt in their daily lives. But salt is not a beast, sodium is one of the essential nutrients for the human body.

Eat a balanced and moderate diet, no matter what is best eaten in moderation, it is not good to eat too much and too little, including salt.

Precautions for edible salt

1. Buy less and eat in time.

Buy in small quantities and buy again after eating, with the aim of preventing the volatilization of iodine. Because potassium iodate will decompose and volatilize under heat, light, wind and humidity conditions.

2. Avoid high temperatures.

When stir-frying vegetables and making soup, avoid putting iodized salt at high temperatures. When stir-frying and stir-frying, iodized salt is put in the pot, the consumption rate of iodine is only 10%, and the consumption rate of iodized salt in the middle is 60%; When out of the pot, the consumption rate of iodized salt is 90%; The consumption rate of iodized salt can reach 100% when cold dishes.

3. Do not store it in the container for a long time.

If iodized salt is in contact with sunlight and air for a long time, iodine is easy to volatilize. It is best to put it in a colored glass bottle, and after use, the cap is tightly closed and stored.

4. Do not add vinegar.

Iodine is destroyed when it binds to acids. According to tests, if vinegar is added at the same time when stir-frying, the consumption rate of iodine will be reduced by 40% to 60%. In addition, when iodized salt encounters sour vegetables (such as sauerkraut), the consumption rate will also decrease.

The main component of table salt is sodium chloride, of which 39% is sodium and 61% is chloride. Table salt can be broken down into sodium ions and chloride ions in the human body, which play different roles. Sodium ions can maintain the body's blood volume and cell osmotic pressure, maintain the normal excitation and stress of nerves and muscles, and activate human muscle contraction.

Chloride ions help regulate the body's acid-base balance, produce stomach acid and activate amylase. These are extremely important for life activities. Many people in life know that a high-salt diet is not good for health, so they one-sidedly think that eating less salt is better, or even not eating salt, which is actually a misunderstanding.

As we all know, high salt can increase blood pressure, low salt can lower blood pressure, northerners eat more salt than southerners, so northerners generally have higher blood pressure than southerners. Doctors also often advise patients with high blood pressure not to eat too salty and to eat a lighter diet to help control blood pressure. In fact, not all people who eat a lot of salt will develop high blood pressure.

Studies have shown that about 1 in 5 people are sensitive to salt. These people develop high blood pressure when they eat too much salt, and if they already have high blood pressure, it can make their blood pressure even higher.

A study of 1,900 hypertensive patients abroad for 4 years of observation, regular analysis of their urine salt content, found that the patient with the lowest urine salt content is 4 times higher than the normal content of myocardial infarction. So, even if you have high blood pressure, it's not that the less salt you eat, the better. At present, medicine cannot distinguish people who are sensitive to salt, so the World Health Organization recommends that the daily salt consumption should be controlled to less than 5 grams.

A low-salt diet does not mean that eating less salt is better, nor does it mean that you don't eat salt. If the salt restriction is excessive, there will be a certain ***. Insufficient sodium intake will cause the osmotic pressure inside and outside the collective cells to lose balance, promote water into the cells, produce cerebral edema of varying degrees, and disorders of consciousness will occur in mild cases, including drowsiness, fatigue, and confusion, and coma may occur in severe cases.

If the intake of salt is excessively restricted for a long time, it will lead to low serum sodium content, which will cause neurological and psychiatric symptoms, loss of appetite, weakness of limbs, dizziness and other phenomena, and in severe cases, anorexia, nausea, vomiting, rapid heart rate, weak pulse, muscle spasms, blurred vision, decreased reflexes and other symptoms, which is medically called "hyposodium syndrome". Extreme salt restriction can reduce fluid volume and increase the activity of the renin-angiotensin system and sympathetic nervous system, which can lead to an increase in blood pressure in some patients.

Is a low-salt diet a healthier if you consume less salt? I don't know how to solve it, so I will collect and sort out the low-salt rent diet is the less salt intake the healthier? Solution, if you are interested, come and take a look.

a.Not.

b.Of course.

Correct Answer: Not really.

Analysis: Although excessive salt intake increases the risk of many chronic diseases, such as high blood pressure, cardiovascular disease, and kidney disease, an overly restrictive low-salt diet can also lead to health problems.

Salt (i.e., sodium chloride) is essential for maintaining fluid balance, nerve and muscle function, and an overly strict low-salt diet may lead to some health problems, such as:

Low blood pressure: Consuming too little salt can lead to a decrease in blood volume, which can lead to hypotension.

Kidney disease: Eating too little salt may affect the normal function of the kidneys, especially for some people with kidney disease, and an overly restrictive low-salt diet may worsen the disease.

Malnutrition: Consuming too little salt may affect the body's ability to absorb and utilize other important minerals such as calcium, magnesium and iron.

Therefore, a low-salt diet is not about getting healthier with less salt, but needs to be adjusted appropriately according to the individual's health status and nutritional needs.

Medical experts have confirmed that too much salt is harmful to the human body, it can cause high blood pressure and cause damage to important vital organs such as the heart, brain, and kidneys. For example, residents in northern Japan eat 26 grams of salt per day, and the incidence of hypertension is 40; Indigenous people in parts of Africa, who eat 10 grams of salt per day, have an incidence of 8 6; Eskimos eat less than 4 grams of salt per day, and no hypertensive patients have been found in the population. Therefore, developed countries in Europe and the United States launched the "anti-salt movement" in the 50s, asking people to eat less salt.

Now, a variety of medicines** are still promoting the health benefits of low salt consumption. In the ** propaganda with different opinions, people are a little afraid of salt, and some even dare not eat salt. Whether you want to eat salt or not, the answer is yes:

Don't skip it, and don't eat too much. So, how much salt should each person eat?

According to the recommendations of the World Health Organization: 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 patients with mild hypertension, the US Committee on Nutrition and Human Needs recommends a limit of 4 grams.

This standard is also suitable for patients with cardiovascular and cerebrovascular diseases in China. Here's a rough calculation. After you buy 500 grams of table salt, write down the date of the purchase of table salt, and when the 500 grams of table salt are eaten, then you will know the 500 grams of table salt.

The number of days eaten can be roughly derived by dividing the amount of salt eaten by the number of days eaten and then dividing by the number of people in the household. For example, if you have a family of 3 and buy 500 grams of salt and eat it for 20 days, how much salt do you eat on average every day? 500 g 20 3 people.

8 3 grams. If you have more salt than you can use for your health, you should take care to reduce the amount of salt.

Another thing to note is that soy sauce is also another major salt in our diet**. Therefore, the amount of salt ingested through soy sauce should also be added to the calculation of salt intake, 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 consumed by eating soy sauce per capita.

Add this amount to the amount of salt and you'll get the average amount of salt per person in your household per day.

Each person should not exceed 6 grams and not less than 4 grams of salt per day, too much or too little is not good for the body.

Eat no more than 6 grams of salt per day. For people with high blood pressure, it is also relatively safe to consume 10 to 15 grams per day. Salt intake is too low. It also increases the risk of cardiovascular disease and death.

Do not exceed 4 grams, eating too much salt is very harmful to the body, calcium loss is serious, it is taken away, and it is not good for the kidneys.
