Diabetic patients try to eat as little lard as possible. Lard is rich in fat and also high in calories, which is likely to cause fluctuations in blood glucose and blood lipids after consumption by diabetic patients, resulting in adverse consequences. Diabetes is a metabolic disease characterized by chronic hyperglycemia, in the case of abnormal glucose metabolism, can cause lipid metabolism, protein metabolism abnormalities, so diabetic patients are prone to combined lipid metabolism disorders as well as symptoms of wasting. Diabetic patients should pay attention to a low-salt, low-fat, low-sugar diet, and consume high-quality protein, such as lean meat, fish, shrimp and so on. Diabetic patients can consult a professional doctor to develop an individualized diet plan.
