Research has shown that the use of the simple sugar sucrose, as part of the meal plan, does not impair blood glucose control in individuals with type 1 or type 2 diabetes. However, sucrose and sucrose containing foods must be substituted for other carbohydrates, and not simply added to meals.
In making substitutions, consider that many sucrose-containing foods are prepared foods (baked goods, breakfast cereals, frozen desserts) which are often calorie-dense and may contain added fat.
