Nephrologists talk about diet: how to eat a reasonable diet for patients with kidney disease
In addition to treatment, there is no dietary problem that can cause entanglement for patients with kidney disease. This is because the Internet is filled with articles such as “Eating ** leading to kidney failure” or “×× eating uremia”, which makes everyone feel at a loss .
How to solve the diet problem of patients with kidney disease? Today we talk about it.
A light diet is almost a pet phrase for all doctors, but the question is, what is "light"?
The so-called "light" actually refers to the intake of sodium ions, which is simply not easy to grasp accurately, and the specific situation of each patient is not the same (such as whether edema, hypertension, etc.), so the general statement Yes, patients with normal renal function have daily salt control below 6 grams, and patients with renal insufficiency have daily salt control below 3 grams.
People who have actually performed it all know that this is just a taste! (Although I don't know what the wax tastes like...)
To solve this problem, first of all we need to find out: Why do doctors need to reduce sodium intake in patients with kidney disease?
There are two reasons: First, sodium ions are prone to cause sodium retention, which is the common edema in patients with kidney disease; Second, sodium ions may cause high blood pressure, and high blood pressure has a relatively large injury to patients with kidney disease. (Note: The issue of elevated blood pressure caused by sodium ions is currently controversial.)
From these two arguments, we can see that the reason why doctors restrict salt to patients with kidney disease is only to fear edema and high blood pressure, which aggravates kidney disease.
We also know that one of the main functions of the kidneys is to regulate the electrolytes, and the metabolism of sodium ions is also within its scope of regulation. Therefore, if the kidneys regulate the normal electrolyte function, there is actually no reason to limit the salt.
From this we can draw the following conclusions:
The limit is not limited to salt, depending on whether the patient has developed edema, high blood pressure, or electrolyte imbalance. If not, there is no need to limit salt.
This also makes everyone very confused, what is "high-quality protein"? Why "low protein"? What is the "high quality" and "low" protein diet?
First, talk about high-quality protein, which is actually the most easily absorbed protein, that is, the protein whose amino acid pattern is closest to the human body.
Why "low protein"? Because most patients with kidney disease have urinary protein-positive symptoms, that is, proteins leak out, this leakage process can damage kidney cells, especially glomerular podocytes, and cause more protein to leak out. If there are a lot of protein in the body, whether it is good or not, if the kidneys are unable to prevent it, it will increase leakage and cause kidney damage. Therefore, to control protein intake, it is the “low-protein diet”.
In summary, a high-quality, low-protein diet is to ensure that the body's normal protein needs, but also ensure that there will not be too much protein to destroy the kidney cells.
High quality protein is represented by fish, meat, eggs, milk, etc.
Although each kidney patient has a different situation, there is a more general principle: the daily intake of protein is 0.6-1 g/kg body weight.
What are the things that kidney patients can't eat?
not at all.
The so-called dietary taboo, but some people deliberately exaggerated the impact of food on the human body. In fact, if we think about it, we can understand that highly purified drugs are still difficult to produce immediate effects on the human body. What is food?
As long as people can eat normally, people with kidney disease can eat, but some need to eat less.
Some people say that crayfish can cause rhabdomyolysis, which in turn causes acute renal failure, so people with kidney disease cannot eat crayfish.
I want to say how much crayfish I have to eat! If you really eat so much, not to mention kidney patients, normal people can not stand it?
Can kidney patients eat chili?
Eating half a bottle of Laoganma for a meal is definitely not a good thing, but if it's only a little bit as a seasoning, it won't happen.
what? Pepper can cause inflammation, aggravate the condition?
Do you think that the powerful stomach acid and endocrine system are furnishings?
Therefore, unless the kidney disease seriously affects the digestive function, it is not necessary "this can not eat, it can not eat."
After all, the depression caused by the isolation of food is the real killer of aggravating illness!
