Diabetic patients can eat hard-boiled eggs because they contain high quality protein and are healthy food with low oil content and low calorie content, so diabetic patients can eat 1-2 hard-boiled eggs per day. For patients with poor nutritional status and stressful infections, they often need additional protein, so they can eat hard-boiled eggs, but they should not eat too many egg yolks and can increase the intake of egg whites. For diabetic patients with diabetes combined with hypercholesterolemia, it is not recommended to consume too many hard-boiled eggs, but one hard-boiled egg per day. For patients with diabetic nephropathy, because of the loss of protein in the urine, protein intake is controlled to less than 0.8g/kg/d per day, so one hard-boiled egg per day for patients with diabetic nephropathy is sufficient to supplement nutritional protein.
