Patients with kidney disease can eat grapes. The principles of dietary treatment for kidney disease patients are low protein diet, high quality protein diet and low salt diet. First of all, low protein and high quality protein diet is needed, because too much protein intake every day will increase the burden on the kidneys, the glomerulus will sclerosis and the kidney function will decrease, so the protein diet should be limited. Secondly, a low-salt diet is needed, which means limiting sodium intake, because too much sodium intake will cause patients’ edema to worsen and blood pressure to rise. Also note that if the patient has a long course of kidney disease, there may be a decline in kidney function, and at this time, attention should also be paid to a low potassium diet. Grapes belong to the fruit food, mainly rich in some minerals, containing vitamins, the content of sodium and potassium is not very high, so you can eat. However, it should be noted that if the patient’s kidney disease is caused by diabetes, that is, diabetic nephropathy, grapes are not recommended to be eaten at this time, because the sugar content of grapes is high, too much intake of grapes will make the patient’s blood sugar rise, so it is not recommended to eat.
