Therefore, the quality of the kidney determines the detoxification function of our body. In diet, how to maintain the kidneys? What are the signs of kidney problems? How should nutritional support for kidney diseases be done?
Eating too much of these three foods is very harmful to the kidneys! Remember, everyone
People cannot live without salt for a day. Salt is what we eat every day. For the kidney, filtering body water is its most important function. If the salt is too high, the burden on the kidneys will be heavy, and in the long run, it will damage the kidneys.
Human blood is weakly alkaline, and the kidney maintains acid-base balance, that is, electrolyte balance. Na+ in salt will affect the balance of body fluids, and the kidney can't excrete excess Na+ at one time. It needs to be filtered several times to maintain the electrolyte balance in the body.
According to the statistics of the National Bureau of Statistics, Chinese residents eat 9.3g of salt every day on average, and some areas even eat salt 15g every day on average.
People's taste is getting heavier and heavier, which may be related to the pressure of life in modern society. In particular, salt or sodium is now added to processed foods. For example, there is Na+ in potato chips and biscuits. So we eat more and more salt! The damage to the kidneys is getting bigger and bigger!
In 2022, "Dietary Guidelines for China Residents" proposed that the daily salt intake should not exceed 5g, which is about equivalent to a beer bottle cap. And eat less pickled foods, such as pickles, fermented bean curd, sausages, ham and other foods with high salt content. Snacks with high salt content should be eaten less, such as spicy strips and instant noodles.
2. Water
Water has a great influence on health. The correct drinking method can protect the body, and the wrong drinking method will damage the body.
The main function of the kidney is to filter body fluids. If you drink too much water a day, the kidneys frequently filter body fluids, and the pressure is too high, which will cause certain damage and even water poisoning.
The kidney can filter 1L of water at most one hour. If we drink more than 1L at a time, the kidneys can't drain water in time, and there will be headaches, irritability and drowsiness.
It is reported that in Shenzhen, a person who had a B-ultrasound had vomiting, convulsions and other symptoms after drinking 3.2l Fortunately, he was treated in time in the hospital. This is an acute water poisoning incident.
How much water a person drinks every day is determined by his own situation, such as height, weight, amount of exercise, and even the environment will affect the water needed by the body. Eight glasses of water is not enough.
According to the recommendation of the World Health Organization, the total intake of adult males is 2900 ml/day, and that of adult females is 2200 ml/day ... Teenagers and pregnant women can drink more. Old people need to drink water regularly and quantitatively because of their slow response to thirst, and increase or decrease the amount of water according to the amount of exercise.
3. seafood
Seafood is rich in purine, which is converted into uric acid after entering the body, and uric acid is excreted with urine.
If you eat too much seafood, uric acid will accumulate in the body and cannot be excreted by the kidneys. Uric acid will gather in the kidney, bladder and joints to form stones.
If uric acid continues to accumulate, it will be converted into high uric acid, which will damage the metabolism of the kidney and cause great harm. The dietary guidelines for China residents recommend that the intake of seafood should be about twice a week, each time 120~200g. Eating seafood every day, and exceeding 100g, will lead to uric acid accumulation.
In addition to seafood, there are many foods with high purine content, so eat less.
Such as animal viscera, beef offal, duck intestines, etc. The purine content of pig liver is relatively high, so it is advisable to eat pig liver once a week, not exceeding 50g. Gravy and old gravy are also high in purine, so don't eat them every day. Some vegetables are also foods with high purine content, such as green beans, peanuts, peas and various mushrooms.
Avoid uric acid accumulation in the body, causing kidney damage.
All the five internal organs of the human body belong to dumb organs. When you are sick, you won't feel pain. Only when it worsens to the late stage of cancer will you have obvious pain. So how do we judge whether our kidneys are healthy? How can we find kidney disease in advance and treat it early?
There are three main manifestations of abnormal urine in kidney disease.
First, the urine volume is reduced. Drink water normally every day, but the urine output is less than 400mL! Or significantly less than the amount of water consumed.
Second, hematuria, urine has obvious red sediment, which is caused by red blood cells.
Third, proteinuria, mainly manifested as urine foam, is easy to attract mosquitoes and flies, which is a nephropathy caused by diabetes.
In the above three cases, you should go to the hospital for a urine test.
1, edema
Face, feet and eyes are prone to edema and often edema. After a week of light diet, it is still edema, and an ultrasound examination of the kidney is needed.
2. Anemia
Mild and moderate anemia may also be caused by the decrease of erythropoietin secretion by the kidney, and it is necessary to go to the hospital for examination to determine the cause of anemia.
It is worth noting that kidney disease can also lead to an increase in blood pressure. Middle-aged and elderly people should also check their kidney health when their blood pressure rises.
3, impaired digestive function
Kidney disease can lead to loss of appetite, nausea and vomiting, and the most obvious feature is the smell of urea in the mouth. The digestive tract is prone to bleeding, bloody stool and gastric ulcer.
4. Abnormal nervous system
Getting up early with kidney disease can lead to lack of energy, fatigue, depression, memory loss, and even hallucinations and mental disorders. I often feel numb and hot in my limbs. Occasionally muscle spasms or weakness.
These are all central nervous system disorders caused by kidney diseases. You should go to the hospital immediately to check five items of renal function.
So you're already a kidney patient. What are the precautions in diet? What to eat? What's not delicious?
