NO.1: Eat only vegetarian dishes, not non-vegetarian dishes. Due to overemphasis on the diet of children with kidney disease, the staple food and protein intake of the children is much restricted, and the lost protein cannot be replenished in time, resulting in decreased body resistance and hypoalbuminemia, which can easily aggravate the disease. Therefore, in the early stage of kidney disease without renal function damage, it is not necessary to restrict protein intake, and only when renal function declines should we start low protein diet therapy. We advocate a balance of meat and vegetables to meet the body’s various nutritional needs, avoid greasy, limit the intake of high cholesterol foods, such as animal offal, egg yolk, fish roe, pig’s feet, meat skin, chicken skin, etc., it is appropriate to eat chicken “white meat” meat dishes, less consumption of lamb and other “red meat “The intake of protein should be to meet the needs of the body and not increase the burden on the kidneys as a standard. NO.2: do not eat salt, drink less water. We all know that water and salt are directly related to edema, so many patients pay special attention to eating salt and drinking water, resulting in the “fear of salt” and “fear of water” psychology. In order to avoid excessive water and sodium retention, which will aggravate edema and hypertension. If there is no such condition, the intake of water and salt should not be particularly restricted, and a low-salt diet should be adopted to control the intake appropriately, rather than absolutely no salt. Not eating salt can lead to a lack of sodium in the body and weakness, convulsions, and hypotension. And when the urinary tract infection is required to drink more water to maintain sufficient urine volume to ensure sufficient water in the body while not increasing the burden on the kidneys. NO.3: to shape to complement the shape, eat waist to fill the waist. Most people think that “eat waist to make up for the waist”, many people regard pig kidney as the best tonic, which is wrong. Pork kidney contains high uric acid and purine, eat more, these harmful substances in the kidney is not easy to discharge, easy to cause stones and gout. When the kidney function is damaged, eating more will increase the burden on the kidneys, which is not beneficial.
