Abstract: Diet plays a vital role in the diabetes incidence and glycemic control.Numerous researches reveal that high-carbohydrate and high-fat（HCHF） diet has an important impact on the incidence of T1DM and T2DM as well as glycemic control.Therefore，the control of HCHF diet can contribute to the control of glycemic level.Blood glucose is influenced directly by the high proportion of carbohydrate intake in the total amount of calories，eating red meat，eating processed meat and drinking soft drink.In contrast，vegetarian diet is conducive to reducing the incidence of diabetes，and Mediterranean diet including milk，olive oil and fish is also beneficial to the prevention and control of diabetes.The studies concerning the relationship between diet and diabetes have been reviewed systematically，in order to guide diabetic patients to have a reasonable diet.
