People with diabetes should not eat foods high in fat, sugar or salt and avoid alcohol. Diabetics should keep their diet light. Avoid eating foods high in fat such as animal offal and fried foods, foods high in salt such as pickles, squash and salami, and foods high in sugar such as chocolate, cookies and milk tea. Because the above foods will cause large fluctuations in blood sugar after eating, and also prone to hypertension, high blood pressure, high blood fat and other comorbidities. In addition, diabetic patients should not drink alcohol, because long-term alcohol consumption can cause an increase in blood glucose, and a large amount of alcohol can cause fatty liver, which is not conducive to blood glucose control. Patients diagnosed with diabetes should actively cooperate with doctors for treatment.
