Children’s nephritis diet should first pay attention to low-salt diet. Eating too much salt may aggravate edema, cause high blood pressure and aggravate the burden on the kidneys, and at the same time, we should eat less of all kinds of high oil and high fat foods, which can cause hyperlipidemia. Other dietary contraindications for different types of nephritis are also different, for example, patients with a large amount of proteinuria, if the urine protein quantification is greater than 3.5g/day, you also need to pay attention to the high-quality low-protein diet, the daily protein intake is controlled at about 0.8g per kilogram of body weight, and high-quality proteins are the mainstays of the diet, such as fish, chicken, skimmed milk, eggs and so on. If there is a high degree of edema and oliguria, it is also necessary to strictly control the intake of water. If there is hyperkalemia, it is necessary to limit the intake of potassium-rich foods, such as vegetable soup, bananas, cherries, strawberries and so on.
