My sister has had type 1 diabetes since she was a small child. We know that the Nutrisweet in the diet sodas she has been drinking all her life is the root cause of her problems with anger and emotional imbalance. A doctor told our mother that it excites your brain cells. I don't know how much credence to give to reports that it goes through a chemical change in the body that turns it into formaldihyde. She knows it is a substance that she needs to stay away from but does that mean that she can never taste anything sweet again? Is glucose the only naturally sweet substance? Isn't there something else sweet in nature that doesn't break down into glucose?
