Patients with kidney disease should pay attention to control salt intake and try not to eat high protein and high fat food. 1. Control salt intake: the glomerular filtration function of patients with kidney disease is abnormal, eating foods with high salt is easy to cause sodium retention in the body, aggravating the burden of glomerular filtration function, which in turn triggers edema, high blood pressure and other undesirable symptoms, so it is required that salt intake is controlled within 4-6 grams per day. 2. High protein: Due to the impaired glomerular filtration function, patients with kidney disease consume too much high protein food, which will easily lead to glomerular filtration of more protein, proteinuria, and may also cause damage to the glomerular filtration membrane, which is not conducive to the health of patients with kidney disease. 3. High fat: high fat food contains high content of cholesterol, patients with kidney disease eat more high fat food is easy to cause arteriosclerosis, triggering cardiovascular and cerebral diseases. In addition, if patients with kidney disease are combined with moderate to severe renal insufficiency, they should also pay attention to limiting the intake of high potassium foods, such as bananas, oranges and so on. Patients with kidney disease should pay attention to light diet, try to eat less or no spicy, stimulating food, adjust the routine of work and rest, pay attention to rest. It is recommended that patients should go to the hospital for regular checkups and follow the doctor’s instructions for treatment.
