Current medical wisdom does not impose any ban on any particular foodstuff for diabetics. On the contrary, it calls for a diet perfectly balanced in terms of calorie and nutritional constituents which should be uniformly distributed throughout the day. Nowadays we also allow diabetics to have simple sugar to the extent of 30g per day. But mind it that the sugar should not be consumed at a time and should be taken with complex carbohydrates like chapatti, breads, rice and so on. You can have sweet drinks and artificial sweeteners. In addition physical exercise like daily brisque walks can keep your calorie count under control.
