Diabetes Mellitus is a group of metabolic diseases characterized by hyperglycemia (high blood sugar) resulting from defects in insulin secretion, insulin action or both. Diabetes is divided into type 1 and type 2. There is no one “diabetic” diet. The recommended diet is a nutrition prescription based on assessment and treatment goals and outcomes. Medical Nutrition Therapy for people with diabetes is individualized, with consideration given to usual eating habits and other lifestyle factors.
