As we all know, the dietary requirements for kidney disease are very strict and have specific guiding principles. At present, the "five lows and one high" dietary principle is still used, and there are also the sayings of "two highs", namely low salt, low fat, low protein, low potassium, low phosphorus, high vitamins, and high cellulose. If kidney friends have urine protein , high creatinine, kidney failure, etc., you can click →→ here "
adhere to the correct diet principle is part of kidney disease treatment. Taking "right" is more effective than taking more medicine!
Kinetic disease diet Eat less this food can play a long-term role in protecting kidney function, and at the same time help lower protein and blood pressure!
It is sodium salt!
It can be seen that the "low salt" diet is ranked first, followed by "low fat" diet. It is worth noting that these two major dietary principles basically start from the day you diagnosed with kidney disease. What you need to start following is not directly related to the influencing factors and pathological types mentioned above.
From previous studies have shown that a low-salt diet can reduce the renal metabolic filtration function, stabilize urine protein and blood pressure indicators, and thus help delay the progress of renal function.
Top medical journal NEJM has published a study on salt intake and physical health. The research results show that having a long-term high-salt diet will cause direct damage to the kidneys, heart and blood vessels, and it is partially irreversible.
is clearly stated in Dietary Guidelines for my country, , healthy people Dietary requirements are ＜6g of salt per day. It is recommended that patients with kidney disease should not exceed 6g of salt a day (about 6g of a beer bottle cap). Now there is a limited salt spoon, so you can know what you can do when cooking.
. For patients with kidney disease with hypertension , edema, and proteinuria, it is crucial to strictly control the daily salt intake.
Another top nephrology journal JASN published a related study:
randomized double-blind control experiment, which compared the high-salt diet and low-salt diet for proteinuria and blood under different treatment methods. The effect of pressure. results found that low salt alone can reduce urine protein by 26% , thereby reducing damage to the glomerular basement membrane, protecting the glomerulus to avoid sclerosis, and thus delaying the progress of overall renal function.
Therefore, adhere to a low-salt diet, correctly consume salt in daily life, and a light diet can help better protect kidney function.
So the question is, can low sodium salt be replaced with a low-salt diet?
Some patients with a large amount of proteinuria, high edema and high blood pressure often leave messages to ask this question: "It is troublesome to calculate how much salt to eat every day. Sometimes I can't control it when I go out to eat, so can I eat low sodium? "
Let's first look at what is the difference between low sodium salt and ordinary salt?
low sodium salt contains the same iodine salt, but in addition, potassium chloride is added to about 30%. It can help regulate blood potassium in the body and prevent hypertension.
But is it suitable for nephropathy patients? From a long-term perspective, it is not suitable for long-term use as a substitute.
As the patient with kidney function progresses, in addition to encountering proteinuria and hypertension, he will also experience acid and alkaline and electrolyte imbalance, causing hyperkalemia . Low sodium salts contain high potassium chloride, and long-term consumption can easily induce hyperkalemia , which aggravates renal metabolism and causes slow heart rate, sudden stop , as well as stiff limbs, numbness and other spirits The system situation threatens physical health.
Previously, research teams in many countries have also published the impact of low sodium and high potassium on prognosis in nephropathy treatment!
A randomized controlled study analysis showed that for kidney friends in any stage, persists in reducing the intake of sodium chloride 4.2g or 1.7g sodium per day for a long time, which can reduce systolic blood pressure (high pressure) by -6.9mmHg and diastolic blood pressure (low The pressure decreases -3.9 mmHg and proteinuria (-36%) have positive significance for protecting the heart and kidneys.
, but it has no conclusion on increasing potassium intake, and it is currently not confirmed that it has positive benefits for kidney function.
According to the definition of World Health Organization (WHO), the average person's daily potassium intake is between 3.5 and 4.0 g.In fact, I eat a balanced diet every day, consume enough 500g vegetables and 200g fruits, and the potassium intake a day is basically enough.
If you consume low sodium salt for a long time, it may cause the potassium content to exceed the standard. For patients with middle and late stages of renal failure, it is recommended to limit potassium intake to 3 grams per day to prevent and treat hyperkalemia.
. As the glomerular filtration rate of decreases and the blood endotoxin level increases, the renal metabolic filtration capacity decreases, and it will be difficult to consume normally in time. Eating more extra points will undoubtedly increase the difficulty of excretion, and the risk of hyperkalemia increases.
So it is recommended that you follow a good low-salt diet, there is no need to eat low-sodium salt or high-potassium salt, etc. I would like to remind everyone again that the therapeutic significance of a low-salt diet is equivalent to reducing blood pressure drugs. You should take it seriously, but don’t harm your already damaged kidneys just for the sake of greed. If you have kidney friends who need to answer kidney disease questions, you can click "
