"Kidney patients eat less salt," which has become an iron law, all medical staff are patiently admonishing patients and their families: eat as much as a beer bottle cap so much salt every day, or the consequences are serious.
Is eating salt in patients with kidney disease really worse?
In fact, it is to reduce the sodium ion intake.
Because one of the main functions of the kidneys is to balance the electrolytes, after the kidneys have problems, this function is affected.
Once the sodium ion content is too high, sodium ions remain outside the cell, increasing the reabsorbed water in the renal tubules, there will be edema, which is called renal edema.
But the greater harm caused by excessive sodium ions is actually high blood pressure.
The reason why eating more salt to cause high blood pressure is that water and sodium retention cause cells to increase, leading to narrowing of the blood flow channel; second, sodium ions destroy the inner wall of blood vessels and increase blood flow resistance.
Therefore, patients with kidney disease eat less salt, one to prevent edema, and the other is to prevent blood pressure.
Since patients with kidney disease should eat less salt, how much should they eat?
In simple terms, in the case of normal renal function (normal serum creatinine), it can be controlled within 6 grams per day.
Once severe edema or renal insufficiency (increased serum creatinine) occurs, it should be controlled within 3 grams per day.
Some people say that if you do not eat salt, what is the cause of hyponatremia?
This is the idea!
Because other foods also contain sodium ions, for those foods rich in sodium ions, such as bacon, sausage, oats, soy sauce, etc., but also the right amount.
A lot of people's opinions on the diet of the patient make people feel that after reading, they will always come to the illusion that “this can't be eaten, and that can't be eaten”.
In fact, no matter what kind of disease, there are only two dietary principles: one is up to eight points full, and the other is not biased towards a certain type of food.
First, the meaning of eight-point fullness is to control food intake within 80% according to the patient's current standard of appetite;
Second, the meaning of not being biased towards a certain kind of food is not to eat more because certain foods are good, and not to eat completely because certain foods are not so good. The balanced combination of various nutrients is the king.
For example, patients with kidney disease who eat less salt will definitely not allow you to cook boiled cabbage, and even a variety of sauces, seasoning bottles, sodium foods will be abandoned, but instead of salty as usual.
Remember that the bias to a certain type of food is exactly the source of most medical problems.
