Diet is always a important part in the treatment of kidney disease. Eating healthily and scientifically for patients is a prevention of the progression of kidney disease as well as some complications.
1. Limit salt and fat intake
Salt limit: When kidney disease patients have swelling or high blood pressure, they should strictly limit their salt intake. Generally speaking, 2-4g is OK for them. Low salt intake can prevent water-sodium retention so as to prevent swelling and high blood pressure. And low fat intake can prevent glomerular sclerosis, because high level of blood fat will cause ischemia and anoxia of the blood vessels in kidneys. Therefore, it is good for patients to cook with plant oil, and control the intake of fat under 60-70g every day. In that case, sunflower seed oil and olive oil can be your choices. They can be taken as the source od energy because they contain few saturated fatty acids that can increase the cholesterol level.
2. Choose high-quality protein
Too much protein intake will burden the kidneys, while less protein intake may not meet the needs of nutrition of the body. Essential amino-acid that is transformed from protein is a necessary for us. Therefore, in your daily diet, you should avoid foods with plant protein which contains much purine. Milk, fish, lean meat and egg white are all OK for patients with kidney disease.
3. Supply calories
If the calory supply is deficient, the body will break down more protein to provide energy. As a result, more wastes such as creatinine and urea nitrogen will be produced and accumulate in the body. 30-35 kilocalories per kilogram of body weight is recommended. You can choose some foods containing high calory but low protein, such as potatoes, taros, and pumpkins, etc.
Besides, potassium and phosphorous intake should also be limited based on the patient’s specific condition. Vitamins supplements should also be included in the diet list of kidney disease patients.
