Diet in patients with diabetes is an important component of comprehensive diabetes management and is the basic treatment of diabetes. Patients with poor adherence to dietary control have difficulty achieving the desired level of metabolic control. Poor dietary structure and habits may also lead to the development and exacerbation of hypertension, dyslipidemia and obesity. Both diabetic and pre-diabetic patients need to receive individualized nutritional therapy according to their treatment goals, which is best done under the guidance of a physician familiar with diabetes treatment. The total energy intake should be controlled and various nutrients should be distributed in a reasonable and balanced manner. Total energy intake should be reduced according to body weight, especially in overweight and obese people. The goals of dietary control for diabetic patients are to achieve and maintain ideal blood glucose levels; reduce risk factors for cardiovascular disease, including dyslipidemia and hypertension; provide a balanced nutritious diet; reduce pancreatic β-cell load; and maintain a reasonable body weight (the goal of weight reduction for overweight/obese patients is to lose 5-10% of body weight in 3-6 months. (Lean patients should regain and maintain their ideal weight in the long term through a balanced nutrition program). 1.Can I eat fruits? Of course you can.
