Dietary precautions for patients with kidney disease include: using less high protein food, using less high salt food and limiting fluid intake. Use less high protein food: eggs, milk and other foods are rich in protein, but patients should strictly follow the doctor’s instructions to limit the dosage when supplementing protein. Because taking too much protein will aggravate kidney damage. Use less high-salt food: Foods with high salt content, such as sausages, salted vegetables, canned food, etc. Kidney disease patients consume too much salt, which will cause the metabolic burden of the kidneys, and water retention in the body is serious. Restriction of fluid intake: Kidney disease patients often combined with edema, at this time need to limit fluid intake according to the edema situation. Kidney disease patients should go to regular hospitals in time, under the guidance of physicians for standardized treatment and reasonable diet.
