Patients with lupus nephritis can eat eggplant. The principles of dietary treatment for patients with lupus nephritis are basically the same as the principles of dietary treatment for nephritis, which are low protein, high quality protein and low salt diet. A low salt diet also means limiting sodium intake, because too much sodium intake will cause the patient’s edema to worsen and blood pressure to rise. Second, eat high quality protein and low protein, because excessive protein intake will aggravate glomerular sclerosis, and also pay attention to the fact that kidney function will decline with the prolongation of lupus nephritis disease, and this time we should pay attention to low potassium diet. Eggplant is a vegetable food, mainly rich in some minerals, potassium, calcium, iron and vitamins, but the content of sodium and potassium are not very high, so it is possible to eat. However, it should be noted that from the perspective of Chinese medicine, eggplant is cold in nature, so if a patient with a cold body has diarrhea, it is not advisable to eat more eggplant at this time.
