It is okay for diabetics to eat sweets such as ice cream, but with caution, as these foods are usually very high in calories and can wreak havoc on your blood glucose control. They add empty calories to your diet and provide very little nutritional benefit. There are NO foods which must be completely excluded from diabetic diet. It is also NOT necessary to avoid sugar competely. It IS necessary to follow the advice of your medical team and follow a diet that achieves a healthy weight.
