Yes! The fruit sugars are what will help anyone with diabetes, as confusing as that may sound.
Every one of our trillions of cells require carbon and oxygen (from simple carbohydrates) to produce the cellular energy known as ATP. Without this energy source our cells will eventually weaken.
Simple sugars from fruit (fructose) do not require the use of insulin to diffuse into the cells, so eating a high fruit diet will not tax your pancreas in the way that even eating vegetables or complex carbohydrates would.
The key is to strengthen the cells (by providing readily available ATP) and opening your eliminative pathways (kidneys, liver, colon, skin) to allow acidic wastes to leave the body.
When initially increasing your fruit intake as a diabetic, there will always be an initial loading of blood glucose levels but it will eventually balance itself out.
Good luck and good health to you and your family!
