Diet limit potassium (eat less potassium), is it good for health?
If you ask kidney friends, everyone has a "consensus": "low potassium diet, a good way to eat the kidneys"
p ID = "34jdgsq4"> Every time the kidney is online to write a certain kind of good food for the kidney, some people always say, "Its potassium is too high, and patients with kidney disease cannot be eaten!" However, do patients with kidney disease really need potassium?Today, I will discuss this topic with you.01
Potassium, actually unhealthy
Potassium and sodium are very important electrolytes for the human body.
Eat less salt (essentially less sodium) helps to control urine protein, blood pressure, delay the progress of kidney disease, and reduce disease riskEssenceWhether it is early or advanced renal diseases, low -salt diets are controlled to control the disease, including delaying the deterioration of kidney disease, reducing edema, and reducing proteinuria.
However, potassium is the opposite of sodium, and potassium eats too little, but affects health!
Low potassium intake to reduce sodium excretion, high potassium intake increases sodium excretion.
The potassium ion channel in the distant tubular basement film plays a key role in the potassium "perception" of potassium. Potassium It has a regulatory effect on the nephrotic vascular tension system. Low potassium hemorrhage will activate the RAS system and promote the progress of kidney disease. (This is why people who are accustomed to high -salt diet, eating more potassium -containing foods will reduce health damage)
and hypotaldiamia by inducing autophaization andPromote the flat muscle calcification of vascular, lead to calcification of blood vessels and promote arteriosclerosis.
Authoritative evidence-based medicine UTD guidelines clearly point out: low potassium diet and blood pressure, cardiovascular disease diseaseThe increase in risk of chronic kidney disease is related to [1].

PublishedA study shows that potassium intake is too small, which is related to the increase in stroke risk [2]:
Blood potassium in normal range helps maintain the stability of the cell membrane, and a study of the authoritative journal of cardiovascular disease, a study of cardiovascular disease journals.Below is lower than the normal range, it is related to the endless ending (death, end -stage renal disease).
02
Eating potassium is enough to help discharge sodium and lower blood pressure!
Potassium is mainly derived from fresh vegetables and fruits. If you eat rarely in these two categories of food, it basically belongs to people with insufficient potassium intake.
Most potassium will be excreted through the kidney. When the potassium intake is greater than 4000 mg, it can increase the excretion of sodium urine and help control blood pressure [4].The principle is that there is a transit protein on the renal tube. When it perceives that the potassium that people eat are not enough, it will activate and absorb sodium from the original urine to reduce sodium excretion and cause blood pressure to rise.
When eating enough potassium, it will be suppressed, the reducing sodium absorption is reduced, and it will be discharged smoothly from the original urine, resulting in blood pressure, leading to blood pressurereduce.
A survey of the China Centers for Disease Control and Prevention shows [5], only 1547mg of potassium per day per day in Chinese residents, while the sodium intake is as high as 6046mg.Obvious sodium exceeding standards and insufficient potassium!
That is to say, although the diet of low sodium and high potassium is healthier (where can you do it every day, go to the restaurant, where can you do), the current general reality situationBut it is high sodium, low potassium!
So how to ensure sufficient potassium intake?
It is very simple, eat more fresh vegetables (1 catties per day), fresh fruits (half a catty per day)
03
Low potassium diet, there must be it
But why Some kidney doctors will say to some kidney friends, "eat less high potassium food?"
This is mainly related to renal function .
When the patients kidney function drops to below 30 ml/min/1.73㎡ , the ability of the kidney excretion of the kidneys has decreased significantly, and the potassium kidney that can be eaten cannot be discharged. The kidney friends are prone to hypertrophemia, resulting in fatigue and numbness. Severe hyperkalemia can cause arrhythmia or even sudden death. Hypertrophemia is very dangerous.
So in the middle and late stages of kidney friends, you must pay attention to your blood potassium value. If blood potassium often exceeds 5mmol/LThe food is restricted, and the daily potassium camera is reduced by half (within 2000mg).
However, this suggestion is " as a last resort ", only for patients with potassium discharge or hyperkalemia.We!
For most of our kidney friends, their kidney potassium excretion ability is acceptable, and sufficient potassium intake generally does not cause bloodPotassium rises high. These kidney friends with high potassium are hard to follow the wind and potassium, which is harmful to health rather than benefit!
Dont be blindly afraid of high potassium food!
It is recommended that kidney friends pay more attention to their blood potassium value, which itself has hypertrophy, or tend to be hypertrophy.The most important thing for those who are declining and eating Satan/Pribli/奈 omitone/Chinese medicine), the most important thing is the low potassium diet with potassium reduction drugs.
According to the "Suggestions and Management Experts of Hypertrophic Leemia Lessonal Risk Evaluation and Management", the following table can be used to determine the risk of high potassium:
The glomerular filtration rate decreases; taking Salutan/Puli drugs; hypertrophemia, diabetes, heart failure, acid poisoning, are taking Chinese medicine, maintaining sexual hemodialysis kidney friends; ageMore than 70 years old; kidney friends with a score of 4 or more need to strengthen blood potassium monitoring ↓
You can use the kidney program to query eachPlanting foods with potassium high and low. Pay attention to remove the ingredients before cooking, you can also remove some potassium.
04
The limit of this limit is not limited!
Many kidney friends check blood potassium more than 4 oclock, and start to worry about whether the blood potassium is high?
In fact, not! Normal blood potassium is between 3.5-5.0mmol/L . The blood potassium at more than 4 oclock is very perfect. There is no problem.
In short, partners must learn to determine whether potassium is limited to combining renal function, potassium value, and medication history.
PS: If you do n’t understand, go to the kidney to go online (usually software, search kidney online, yellow icon) to consult health coaches!
