Diabetic nephropathy has high blood potassium, so you can choose foods with relatively low potassium and sugar to eat. For example, among vegetables, cucumber, towel gourd, eggplant, onion, Chinese cabbage, zucchini, cabbage, etc., these vegetables can be blanched with boiling water before eating, so that part of the potassium can be removed. Among fruits, apples and pears have relatively low potassium content. However, for diabetics, eating fruit may be harmful to the control of blood sugar. If high blood potassium occurs in diabetic nephropathy, renal function may have been damaged. At this stage, blood potassium can not be controlled at an ideal level only through diet. Therefore, potassium lowering drugs or other measures can also be used to control blood potassium in a safe range, Otherwise, stubborn hyperkalemia may cause cardiac accidents.
